INTRODUCTION & HISTORY

The Model 15 is a digital recreation of the Moog Model 15 Analog Modular Synthesizer. As an iOS App, the Model 15 enhances the original functionality with powerful new features, including:

• Programmability
• Four-Voice Polyphony
• Ping-Pong Delay Module
• Arpeggiator Module
• Real time, overdubbing recorder
• Ableton Link compatibility
• Uploading and sharing of data
• Extensive MIDI support

In addition to the traditional Moog 952 keyboard and an on-screen recreation of the original Moog Model 1150 Ribbon Controller, the Model 15 also includes a new iteration of the Animoog keyboard
for extended performance expression possibilities.

The Model 15 is MIDI compatible, and each knob and switch can be assigned a MIDI CC# to allow for external control from any MIDI device. MIDI Bridge allows MIDI values to be sent to and received from
other apps, while Audio Bridge allows the Model 15 to operate as an Inter-App Audio instrument or effect processor, capable of adding dynamic filtering to a track in another application, for example.

MODULAR SYNTHESIS OVERVIEW
Long before there were keyboard workstations, samplers, digital audio, and groove-boxes, the modular synthesizer was the instrument that put electronic audio creation on the map. As the name suggests, these instruments were collection of well-chosen modules. Each task in the creation of electronic music (generating a sound, sculpting the tone, controlling the volume, etc.) required a specific, dedicated module. Groups of modules (Oscillators, Filters, Envelope Generators, etc.) could be installed into a single cabinet sharing a stable power supply to create a synthesizer system such as the original Moog Model 15. With nearly no existing or pre-wired physical connection between each module, external patch cables were used to allow audio, control, and trigger signals to move freely from module to module. This ability to have one module deliver a Control Voltage (CV) signal to another module is the foundation of the Voltage Controlled synthesizer, including Voltage Controlled Oscillators (VCOs), Voltage Controlled Filters (VCFs), and Voltage Controlled Amplifiers (VCAs). The only pre-wired exception were the edge-connectors used to connect the original 921A Oscillator Driver to the two 921B Oscillators. In recent years, the emergence of the Eurorack format and the popularity of compact semi-modular hardware instruments (including the Moog Mother-32) have ushered in a renaissance in the open-ended design of the modular synthesizer.

A BRIEF HISTORY OF THE MOOG MODEL 15

In 1973, Moog released a number of modular synthesizer systems designed for maximum versatility and equipped with the latest 921 Series Oscillators, which were hailed for their stability when compared to the original 901 Series. While the larger System 35 and System 55 came housed in a finished walnut cabinet, the much more portable Model 15 featured a latching cover for the control panel, and came clad in the black vinyl wrap typical of guitar amps and speaker cabinets. The innovative Model 15—along with its matching 952 keyboard—allowed for two-voice operation. The Model 15 went out of production in the early 1980s, but was reintroduced in a highly-limited production of 150 pieces by Moog in 2015. The following year—2016—saw the introduction of this Model 15 App.

INSTALLATION NOTES
COMPATIBLE iOS DEVICES
The Moog Model 15 requires iOS 9.3 or higher and has been designed to run on 64-bit devices only: iPad Pro, iPad Air, iPad Mini 2, iPod Touch 6, and iPhone 5S or newer. The display will automatically adjust to make the best use of the available screen space in both Portrait and Landscape modes.

SETUP NOTES
The Moog Model 15 functions as a standalone application; you can also access extended features and connectivity by using a MIDI and/or audio interface with your iOS device. MIDI, Audio, and other settings can be accessed via the SETTINGS tab.

TIP: To achieve optimum performance with your Model 15, disable the WiFi connection or activate the Airplane Mode. Please also refer to the Minimal iOS Signal Processing option under the SETTINGS section of this manual.

NAVIGATING THE MOOG MODEL 15 APP
NAVIGATING THE FRONT PANEL

The front panel has been designed for intuitive, immediate control. Take a few minutes to get familiar with the features, functions, and operations described in this section.

PINCH ZOOM AND PAN GESTURES
The two-fingered pinch and stretch gesture will allow you to zoom in and out, respectively, on the front panel. You can also use two fingers to pan around and navigate the front panel for focus on specific controls.

TIP: These pan gestures can be “flicked” to move with greater agility.

SCROLL BAR
A two-axis scroll bar is located at the right edge of the display. The highlighted grey area indicates the modules currently on the screen. Touch the grey area and slide your finger to bring the module(s) you want to access into view.

TIP: Double tap on this grey rectangle to zoom all the way in or zoom all the way out, depending on the current view.

MODULE ZOOM
Double-tap on an individual module—using a single finger—to zoom in or out on that particular module.

NOTE: Be sure to tap on an empty area of the module; tapping on a knob, switch, or patch point may cause a value change or initiate a new patch cable.

TURNING A KNOB
To turn a knob, touch the knob and slide your finger up and down, or left and right, to change the value. This is the default Linear mode.

NOTE: In the Settings section, under Configuration/Knobs, you can choose the Circular mode, where touching the knob and moving your finger around it in an arc will change the value.

KNOBS - TOOLTIPS
You can see the current value of any knob or switch by holding your finger on it. The value will appear in place of the Bank and Preset information in the Top Bar.

NOTE: You can turn off Tooltips by going to the Settings>Configuration>Knobs Menu and
deselecting TOOLTIPS.

PRECISE CONTROL USING A SECOND FINGER
When turning a knob, place a second finger on the screen to adjust the value with a finer
resolution. It may be easier to use a second finger from your other hand.

RESTORING A KNOB TO ITS ORIGINAL VALUE
Double-tap any knob to restore it to its originally saved value.

FLIPPING A SWITCH
To change the setting of any switch, tap it with your finger. You can also swipe the switch with a single finger.

PUSHING A BUTTON
Certain modules feature push-button controls. To push a button, tap it with your finger.Colored button caps will light up to show the button’s current state.

CREATING & CONNECTING PATCH CABLES
Patch cables serve three functions:


Audio Jack:
Carrying audio signals from module to module.

Control Jack:
Carrying control signals (also known as Control Voltages) from module to module.

Trigger Jack:
Carrying gate/trigger signals from module to module.
In addition, patch cables can be color coded to help keep track of your patching. If you are new to modular synthesis, don’t worry, the Model 15 makes it easy to use patch cables correctly.

MAKING A CONNECTION
Begin by touching a jack and dragging your finger slightly. A patch cable will appear connected to the jack. Now slide your finger to a new jack and lift your finger to connect the cable. Only the jacks eligible for this patch cable will be highlighted; everything else will be grayed out.

TIP: When patching, you can use a second finger to navigate the front panel at the same
time.

You can also double-tap a jack to initiate a patch cable, and then double-tap the destination jack to complete the patch. Once you have started a patch cable in this manner, you can use easily
pan around the front panel.

CABLE COLOR SELECTION
Patch cables appear with the color randomly selected, but you can also select the cable color yourself. To do this, touch and hold a jack and drag your finger slightly; a multi-color arc will appear around the top of your finger. Choose a color for your patch cable by dragging it to one of the colored areas and holding it there until the new color is selected; then drag your cable to the destination jack.

CHANGING A PATCH CABLE CONNECTION
Once you have created a patch cable connection, you can easily change which jacks it connects to; just place your finger on either end of the patch cable and slide it to a new eligible jack.

DISCONNECTING A PATCH CABLE
To disconnect a patch cable, touch either end of the cable, drag it away from the jack to an empty area, and lift your finger off the display. The patch cable will disappear.

MAKING THE PATCH CABLES TRANSLUCENT
A two-fingered double-tap on the screen will make all of the patch cables translucent for easier viewing of and access to the front panel. The same action will return the patch cables to their original state.

NAVIGATING NOTES
Certain iOS features will interfere with Model 15 navigation and performance tools. Use the tips below to avoid any conflicts.

DISABLING CONTROL CENTER ACCESS WITHIN APPS
To prevent the iOS Control Center from opening during a performance, go to SETTINGS
on your iOS device, select CONTROL CENTER and disable Access Within Apps.

DISABLING MULTITASKING GESTURES
To prevent four and five-finger multitasking conflicts with iOS, go to SETTINGS on your iOS device, select GENERAL, select MULTITASKING and then disable the Gestures setting.

USING THE TOP BAR TABS
The Moog Model 15 contains additional controls and features that are accessed using the Top Bar Tabs. The Top Bar is divided into five Tabs: Bank & Preset Information Tab, Tempo/BPM, Undo/Redo, Store/Settings, and Battery.


BANK & PRESET INFORMATION
This Tab displays the name of the current Preset, and the Bank that the Preset is assigned to. The ◄ and ► buttons allow you to quickly move between Presets within the current Bank.

TEMPO
Certain features of the Model 15 App (Delay, Arp, etc.) are tempo dependent.

The current tempo is displayed in BPM (Beats Per Minute). To change the tempo, touch the BPM
value and slide your finger left or right to edit the value. You can also repeatedly tap the concentric circles to the right of the BPM to set the tempo through Tap-Tempo.

NOTE: By sliding up or down, you can set the tempo using a finer resolution.

TIP: Tapping the BPM number will open the larger BPM and Tap-Tempo display. Tapping the larger BPM number will allow you to enter an exact BPM manually.

UNDO & REDO
Pressing the UNDO button will undo the most recent change to a sound. Pressing it again will undo
the change made before that, and so-on.

The REDO button will undo the effect of an Undo operation.

NOTE: You can perform many Undo and Redo operations, however, Undo and Redo history is limited by your device’s available memory.

WARNING: The Undo and Redo history is cleared each time the Model 15 App is re-launched

This icon displays the current battery level of your Apple device.

CHOOSING A CONTROLLER FROM THE SIDE BAR

The Side Bar buttons access the various methods available for playing your Model 15 App.

NOTE: Your Model 15 can also be played from an external MIDI keyboard or controller.

Tapping one of these buttons will open the controller window in the lower portion of the screen. Tapping the button a second time will close the controller. You can also swipe-left from the right screen edge of a controller to hide it, and swipe-right from the left screen edge to show it.

KEYBOARD

This button will open a classic Moog 952-style keyboard with added functions.

KEYS & KEY AREA
Not all keys can be displayed at the same time, so directly above the keyboard is a scroll bar with slider for selecting the keyboard’s playable area. Touch and drag the slider left or right to adjust your playing range. You can also tap either side of the scroll bar to move the slider one octave at a time.

PITCH WHEEL
Under the CONTROLLER OUTPUTS section, there are three PITCH outputs that allow you to send information (voltage) from the PITCH wheel to any control voltage input jack you choose. The PITCH wheel information (voltage) is automatically added to the pitch of the Model 15 921A Oscillator Driver when the CONTROLS TO OSCILLATORS switch is On.

MODULATION WHEEL
Under the CONTROLLER OUTPUTS section, there are three MODULATION outputs that allow you to send information (voltage) from the MOD wheel to any control voltage input jack you choose.

VELOCITY
The location where you initially touch a key (from the front edge to the back) will determine the velocity of the note played. Under the CONTROLLER OUTPUTS section, there are three VELOCITY outputs that allow you to send the VELOCITY output signal (voltage) to any control voltage input jack you choose.

AFTERTOUCH
Sliding your finger further back on a key will determine the amount of pressure applied to a note. Under the CONTROLLER OUTPUTS section, there are three AFTERTOUCH outputs that allow you to send the AFTERTOUCH output signal (voltage) to any control voltage input jack you choose.

NOTE: Activating the [VERTICAL SLIDES AS MODULATION] feature under SETTINGS>CONFIGURATION>CONTROLLERS causes this motion to instead be sent out of the MODULATION Controller Outputs.

TIP: iOS users with 3D Touch equipped devices can use 3D Touch as Aftertouch. To enable this functionality, go to the Model 15 SETTINGS>CONFIGURATION>CONTROLLERS. This feature is not visible on devices that do not support 3D Touch.

TIP 2: iOS devices that support the Apple Pencil can use its pressure capabilities as Aftertouch. This doesn't need to be enabled in the settings.

VOLUME
The VOLUME knob on the keyboard will control the overall volume of the Model 15. This control is for the audio Trunk Lines.

NOTE: This control allows you to saturate the output of the instrument—which may or may not be desired.

GLIDE
Glide provides a continuous change in pitch between notes. The GLIDE knob controls the timing of the glide effect. On the Model 15, the timing is relative. This means that it will take longer to glide to a pitch further away than to glide to a nearby pitch.

HOLD
When On, the HOLD switch causes notes to continue to sound even after you’ve removed your fingers from the keyboard. This is useful for drones and working with the Arpeggiator.

ARP (ARPEGGIATOR)
The ARP Switch activates the Arpeggiator, playing through the notes in a rhythmic pattern determined by the current Arpeggiator settings.

ANIMOOG

The Animoog keyboard adds a series of expressive playing features to the Model 15 first introduced in the Animoog App, including custom scales, pitch correction for bending notes, and polyphonic legato.

KEYS & KEY AREA
Not all keys can be displayed at the same time, so directly above the keyboard is a scroll bar with slider for selecting the keyboard’s playable area. Touch and drag the slider left or right to adjust your playing range. You can also touch and drag either end of the slider to adjust key spacing.

TIP: Tap either side of the scroll bar to shift the keyboard up or down one octave at a time.

PITCH WHEEL
Under the CONTROLLER OUTPUTS section, there are three PITCH outputs that allow you to send
information (voltage) from the PITCH wheel to any control voltage input jack you choose. The PITCH wheel information (voltage) is automatically added to the pitch of the Model 15 921A Oscillator Driver when the CONTROLS TO OSCILLATOR switch is On.

MODULATION WHEEL
Under the CONTROLLER OUTPUTS section, there are three MODULATION outputs that allow you to send information (voltage) from the MOD wheel to any control voltage input jack you choose.

CORRECTION KNOB [CORR.]
The Animoog keys can sense the side-to-side motion of your fingertip on the key. The Correction knob determines how much pitch variation can occur on a single key before triggering a new note. It also defines the smoothness between notes when sliding a finger from one key to another.

VELOCITY
The location where you initially touch a key (from the front edge to the back) will determine the velocity of the note played. Under the CONTROLLER OUTPUTS section, there are three VELOCITY outputs that allow you to send the Velocity output signal (voltage) to any control voltage input jack you choose.

AFTERTOUCH
Sliding your finger further back on a key will increase the amount of pressure applied to a note. Under the CONTROLLER OUTPUTS section, there are three AFTERTOUCH outputs that allow you to send the Aftertouch output signal (voltage) to any control voltage input jack you choose.

NOTE: Activating the [VERTICAL SLIDES AS MODULATION] feature under SETTINGS>CONFIGURATION>CONTROLLERS causes this motion to instead be sent out of the MODULATION Controller Outputs.

TIP: iOS users with 3D Touch equipped devices can use 3D Touch as Aftertouch. To enable this
functionality, go to the Model 15 SETTINGS>CONFIGURATION>CONTROLLERS. This feature is not visible on devices that do not support 3D Touch.

TIP 2: iOS devices that support the Apple Pencil can use its pressure capabilities as Aftertouch. This doesn't need to be enabled in the settings.

VOLUME
The VOLUME knob on the keyboard will control the overall volume of the Model 15. This control is for the audio TRUNK LINES.

NOTE: This control allows you to saturate the output of the instrument—which may or may not be desired.

GLIDE
Glide provides a continuous change in pitch between notes. The GLIDE knob controls the timing of the glide effect. On the Model 15, the timing is relativeOn the Model 15, the timing is relative. This means that it will take longer to glide to a pitch further away than to glide to a nearby pitch.

KB SCALE
The Animoog keyboard allows you to choose from a number of scales and then play them in any key. Pressing the KB SCALE button toggles the SCALES page where the SCALE and ROOT NOTE can be selected. Individual notes in a scale can be turned On or Off here as well.

HOLD
When On, the HOLD switch causes notes to continue to sound even after you’ve removed your fingers from the keyboard. This is useful for drones and working with the Arpeggiator.

ARP (ARPEGGIATOR)
The ARP Switch activates the Arpeggiator, playing through the notes in a rhythmic pattern determined by the current Arpeggiator settings.

ARP (ARPEGGIATOR)

An Arpeggiator is a way of automatically playing the notes held on a keyboard in a rhythmic pattern. Patterns can be saved and loaded independently from a Preset, so that you can use the same pattern with different sounds.

Touch the [+/-] box to open or close the additional ARP parameters.

TIP: The Arp iterates through all voices when the Model 15 is in Polyphonic mode. This causes
patterns to sound very different from Monophonic mode. Experiment with both.

MASTER CONTROLS
The Master controls for the Arp include an On/Off switch, a LATCH button, a RETRIGGER button, and the Master GATE LENGTH knob.

On/Off Switch
You can turn the Arpeggiator On or Off using this switch which replicates the function of the ARP On/Off switch found on the Keyboard and Animoog controllers.

LATCH Button
The LATCH button provides a separate function from the HOLD switch on the controller. When the HOLD switch is engaged, each new note will be continually added to the pattern. By contrast, the LATCH button will also allow you to add new notes to the pattern, but will reset the notes in the pattern once you have removed all fingers from the controller and touched it once again. This makes it simple to arpeggiate changing chords.

RETRIGGER Button
Normally, the Arpeggiator will continue to cycle through the entire length of the Arp Pattern (see Pattern Length below). When the RETRIGGER button is On, the Arp Pattern will reset to the first step if play a new note after first removing all your fingers from the controller.

GATE LENGTH Knob
The Master GATE LENGTH knob determines the articulation, or note length, of each step. Setting the GATE LENGTH to a lower value will create a more staccato effect; setting the GATE LENGTH to a very high value will create a legato transition, preventing envelopes from being re-triggered.

LOAD
Tapping the Load icon will open a list of available Arpeggiator patterns. Tap the name of a pattern to load it. Tap outside the Load Dialogue box or press DONE to cancel. Swiping left on any Arpeggio pattern reveals three icons:

Share/Send
Tap to share the selected Arpeggio with other users via Airdrop, Mail, Message, etc.

Edit/Rename
Tap to edit or rename the selected Arpeggio.

Delete
Tap to delete the selected Arpeggio. If you accidentally delete an Arpeggio, simply press UNDO to restore it.

SAVE
Tapping the Save icon will allow you to name and save a current Arpeggio. Once you are finished, tap to SAVE or CANCEL the operation.

LOCK
Tapping the Lock icon will retain the current Arpeggiator settings as you move from Preset to Preset..

PATTERN LENGTH
Tapping the PATTERN LENGTH box will allow you to select the number of steps (1-8) your Arpeggiator will produce.

OCTAVE RANGE
Tapping the OCTAVE RANGE box will allow you to select the number of octaves your Arpeggiator will play above or below a held note. Octave Ranges: 0, 0..1, 0..1..2, 0..1..2..3 and -1..

STEP SIZE
Tapping the STEP SIZE box will allow you to determine which division of the master Tempo (BPM) the Arpeggiator will use. Step Sizes: 1/4., 1/4, 1/8., 1/4T, 1/8, 1/16., 1/8T, 1/16, 1/16T and 1/32

DIRECTION
Tapping the DIRECTION box will allow you to select the direction in which held notes are played back by the arpeggiator.

Direction Options: UP, DOWN, UP/DOWN, UP/DOWN 2, DOWN/UP, DOWN/UP 2, and RANDOM.

NOTE: When UP/DOWN 2 or DOWN/UP 2 is selected, the notes at the extreme ends of the pattern are repeated as the pattern changes direction. For example, holding down C, E, F, and G on the keyboard with UP/DOWN 2 selected will play the notes as: C E F G G F E C C E etc.

VELOCITY MODE
Tapping the VELOCITY MODE box allows you to specify a velocity level for each note in a pattern. The velocity level for individual notes can be preserved (EACH NOTE), or the overall Velocity of all notes can be determined by one of the following;
• FIRST NOTE or LAST NOTE played.
• MAXIMUM, MINIMUM or AVERAGE velocity of all notes played.
• ZERO Velocity (Velocity is based only on the Arpeggiator’s VELOCITY OFFSET knob positions)
• RANDOM Velocity (Useful creating Sample & Hold-like effects.)

SORT ORDER
Tapping the SORT ORDER box allows you to specify the order in which held notes are played by the Arpeggiator. The Arpeggiator can sort notes in the order that they were played (or the reverse order); from the lowest note to the highest note (or from high to low); and by the velocity at which each key was played—either from lowest velocity to the highest, or from the highest velocity to the lowest.

INDIVIDUAL STEP CONTROLS
In order to achieve greater rhythmic diversity, each step in the Arpeggiator may be individually turned On or Off. Press the individual step button to change its status. Only illuminated steps will sound.

GATE OFFSET
The Individual GATE OFFSET knobs can either lengthen or shorten the note-length of each step in a pattern. The offset is based on the position of Master GATE LENGTH control knob.

VELOCITY OFFSET
The Individual VELOCITY knobs allow specific notes to be played more strongly or more softly in relation to other notes in the pattern.

TIP: Patching out of a VELOCITY CONTROLLER OUTPUT into a CONTROL INPUT on the 904 FILTER will allow you to adjust the position of the Cutoff with the Arpeggiator per-step.

RIBBON

This is a recreation of a vintage Moog Model 1150 Ribbon Controller. Unlike a traditional keyboard with discreet pitches, a Ribbon is more akin to a fretless bass, providing a playing surface that can swoop and slide between pitches.

NOTE: The 1150 Ribbon is the only Model 15 controller that MUST be patched in order to work

PATCHING IN THE RIBBON FOR USE
To use the Ribbon as a basic controller in a preset, simply create a patch cable at the MAIN RIBBON output in the CONTROLLER OUTPUTS section and connect it to the Control input of any module. The most common are the Frequency input of the 921A and the Control Inputs on the 904A.

ON/OFF SWITCH
The Control Voltage section of the Ribbon controller is activated by the On/Off switch at the left end of the playing surface. The Trigger strip of the Ribbon controller is always active

PLAYING THE RIBBON
Touch the Trigger strip in the middle of the 1150 controller to generate a sound (trigger signal). While holding the Trigger strip, take another finger and slide it left or right on the ribbon itself to change the pitch (or output voltage) of the Ribbon controller.

NOTE: When multiple fingers are held on the ribbon, the finger furthest to the right takes priority.

SWITCH 1/2
Switch position 1 is the wide setting, providing a pitch range of over ten octaves. Switch position 2 is the narrow setting, which provides 25% of the range available when using setting 1.

AUX CONTROL
This slider provides a second continuously variable control voltage signal that is made available for patching at the RIBBON AUX output in the CONTROLLER OUTPUTS section.

NOTE: When the Main Ribbon or Aux Controller is released, each can retain its current value, or reset to zero. To set this behavior, go to SETTINGS>CONFIGURATION>CONTROLLERS.

PRESETS
OVERVIEW
The Model 15 can quickly change sounds without the need to re-patch any cables or change any knob settings. There are a number of Presets available to get you started. Each Preset can be edited to your liking, or you can create new sounds from scratch.

Tap the SETTINGS tab in the Top Bar to open the Settings menu. Here, you can set global parameters for the Model 15 including Audio and MIDI settings, knob control preferences, manual, tutorials, and more. Tap the X to exit the SETTINGS Tab.

AUDIO
You may need to adjust these parameters in order for your Model 15 to work with other audio equipment or to achieve peak performance.

BACKGROUND AUDIO
When On, the Model 15 will continue to make sound, and consume battery power while it is running in the background

RECORDER BEEP
When using the RECORDER module, this feature will produce an audible beep on each beat of the initial recording. A four-count will be heard before recording begins.

NOTE: There is no beep when recording overdubs.

MINIMAL iOS SIGNAL PROCESSING
This option improves the audio quality of your Model 15 by minimizing the amount of signal processing in the host device, such as the automatic gain control (AGC). This may cause the App to sound much quieter on your device.

NOTE: This setting is also known as Measurement Mode in other iOS applications.

ECO MODE
Using the ECO MODE reduces the CPU load and improves battery life by only processing the modules that are active in the current Preset. With Eco mode off, the Model 15 generates a constant CPU load and avoids iOS lags.

NOTE: When in the ECO MODE, switching from a Preset with few active modules to a new Preset with many active modules, the CPU may take a moment to come up to speed, and audio crackling may occur briefly.

ABLETON LINK DISABLE/ENABLE
Ableton Link allows the Model 15 to match the Beat and Tempo of Ableton Live or other Ableton Link enabled apps. Ableton Link enabled programs can adjust the tempo on one device, and the other linked applications will follow. Players can drop out, stop their performance, restart and fall back in—and still be in sync.

These commands determine how you and your Model 15 will interact.

CABLE MOTION
When selected, the patch cables will move slightly as your iOS device is moved. When this feature is not selected, the cables will remain static at all times.

LEFT HANDED
Selecting LEFT HANDED operation moves the Side Bar navigation and controller tabs from the right edge of the screen to the left edge of the screen. This mode also reverses the swipe to show/hide behavior for all controllers.

KNOBS
This section allows you to specify how knobs on the Model 15 behave, and what information is displayed when a knob or switch is touched.

TOOLTIPS
When Tooltips is activated, operating any knob or switch causes the parameter name and value to be displayed momentarily in the Bank / Preset Tab.

LINEAR
In LINEAR mode (default), the value of a knob is changed by touching it and dragging your finger up and down or left and right.

CIRCULAR
In CIRCULAR mode, the value of a knob is changed by touching it and dragging your finger around the knob in a circular motion.

CONTROLLERS
These functions determine the behavior of the Model 1150 Ribbon Controller and the Animoog keyboard.

RIBBON MAIN RETURNS TO ZERO
When selected, the value of the Ribbon Controller will return to zero when released. When not selected, the Ribbon Controller will latch to its last held value after the ribbon is released.

RIBBON AUX RETURNS TO ZERO
When selected, the value of the Aux Ribbon Controller will return to zero when released. When not selected, the Aux Ribbon Controller will latch to its last held value after the ribbon is released.

VERTICAL SLIDES AS MODULATION
When this feature is active, moving your finger vertically on a key produces a control voltage, available via the MODULATION jacks in CONTROLLER OUTPUTS.

3D TOUCH AS AFTERTOUCH
3D Touch-equipped iOS devices can use 3D Touch to create an aftertouch signal. This can free up the Vertical Slides motion for sending other modulation information.

NOTE: This option is only visible 3D Touch enabled devices.

MIDI
In addition to simple tasks such as MIDI channel selection, advanced MIDI CC mapping provides extensive real-time control of various Model 15 features and controls.

MIDI INPUT
The INPUT CHANNEL Tab allows you to set the MIDI input channel for your Model 15. You can also select the MIDI device(s) being used to control it in the window below it. In OMNI mode, the Model 15 will respond to all incoming MIDI channels at once. In MPE mode, the Model 15 will properly receive per-note pitch bend, pressure and modulation signals from advanced MIDI Voice-Per-Channel controllers.

BLUETOOTH MIDI
Selecting this option will initiate a search for available Bluetooth MIDI devices. When located, available devices will appear in the MIDI INPUT and OUTPUT list.

PITCH BEND
The amount of Pitch Bend Range up or down is specified here. This can be saved as a global value, or recalled per-Preset.

TIP: When operating the Model 15 from a Voice-Per-Channel controller, it is important to have the Pitch Bend range of the Model 15 set equal to the Pitch Bend range of the controller for musical applications such as polyphonic Glissandi, etc.

RANGE
Tap the Pitch Bend RANGE box, and scroll up or down to specify a Global Pitch Bend value.

LOAD FROM PRESET
When set to On, the Pitch Bend RANGE global value is ignored, and the Pitch Bend value saved with the active Preset will be used instead. When set to Off, the Global Pitch Bend Value is used for every Preset.

SEND NOTES
By default, MIDI note data is transmitted when the Model 15 is in use. To prevent note data from being transmitted, simply turn this feature Off. All other MIDI data will be transmitted normally.

SEND POLY PRESSURE, CHANNEL PRESSURE, & KNOBS/SWITCHES
Selecting this option will initiate a search for available Bluetooth MIDI devices. When located, available devices will appear in the MIDI INPUT and OUTPUT list.

NOTE: These options do not affect the internal sounds.

CC MAPPING
MIDI CC Mapping is useful when using a MIDI controller to play the Model 15. By creating and saving a MIDI CC (Continuous Controller) Map, you can specify which MIDI CC numbers will affect which knobs and features on the Model 15. These maps are recalled independently of Presets.

MAP CC'S
Selecting this option will show a panel map of MIDI CC assignments. If no MIDI CC is assigned, the value displayed will be [ - - ]. To make a MIDI CC assignment, tap a knob or switch, and then operate the corresponding knob or switch on your MIDI controller. The first MIDI CC number that the Model 15 detects will be assigned to that parameter. Repeat this process for other knobs and switches. To manually enter a MIDI CC while in this mode, double-tap any knob or switch. Now enter a MIDI CC and press Set to assign the MIDI CC.

NOTE: The Model 15 needs to see two incoming MIDI CC messages to correctly detect 7-bit or 14-bit MIDI CC operation. The word “14-bit” will appear above the CC number; the LSB value will be equal to the MIDI CC number, and the MSB value will be 32 numbers higher. The Make 14-bit option provides compatibility with devices using 14-bit MIDI control.


SAVE/LOAD CC MAP
There are five options available in the SAVE/LOAD CC MAP menu.

• Clear: Tap the Clear button to remove all current MIDI CC assignments.

• Load: To Load an existing CC Map, select it from the MIDI CC MAPS list and press Load.

• Save: Once you have made all of the necessary MIDI CC assignments, tap SAVE. You will be prompted to name your CC Map. Once you are finished, tap Save to save your CC Map, or choose Cancel.

• Delete: Press Delete to remove the selected MIDI CC MAP from the list.

• Cancel: To Exit the SAVE/LOAD CC MAP panel without making any changes, press CANCEL.

TIP: If you select a MIDI CC MAP from the list and swipe left, you can choose [Share/Send] {icon} to share the selected CC Map with other users via Airdrop, Mail, Message, etc.; choose [Edit icon] to rename your MIDI CC Map; or choose the Delete {icon} to remove it from the list.

BUILT-IN MIDI CCs
Model 15 has a number of MIDI CCs that have fixed behaviors. These can also be used for MIDI CC mapping, but will always continue to trigger their built-in functionality.
This table list all the built-in MIDI CCs.

CONTROL PARAMETER MIDI CC# CC VALUE RANGE

SHARE
The parameters for sharing Audio data are located in this section, as well as the commands for sharing the currently active data in the Model 15—whether it has been saved or not.

AUDIO TRANSFER
These settings affect the Share feature in the Recorder module. When choosing USE AUDIOSHARE or USE AUDIOCOPY, CD QUALITY (44.1 kHz/16-bit) can be selected. USE AUDIOSHARE also allows you to select Highest Quality. This option allows AudioShare to use the currently active sample rate of the device.

PRESETS
From here you can share Preset information via Airdrop, Mail, iMessage, etc.

• Share Current Patch: Tap to share the currently selected Preset.

• Share Current Bank: Tap to share the currently selected Bank.

• Share Current Arpeggio: Tap to share the currently selected Arpeggio.

• Share Current CC Map: Tap to share the currently selected MIDI CC Map.

NOTE: The information shared here is the current data, whether saved or not. For example, if you load a Preset and tweak the filter a bit, it will be the unsaved version that is shared.

SCALES
The Animoog keyboard can be set to play in any of 22 musical scales, and in any musical key. Individual keys can be muted or removed from any scale to create custom scales that can be saved as part of a Preset.

SCALE
There are 22 Musical Scales to choose from. Tap your finger on the Scale box and scroll to select a scale from the list.

ROOT NOTE (KEY)
Any of the 12 musical notes can be chosen as the Root Note for a scale. Tap the Root Note box and select a Key from the list.

When On, the Scale Lock function allows you to retain the currently selected SCALE and ROOT NOTE when changing Presets, regardless of the Scale saved within a Preset.

MANUAL
Select this option to view the Model 15 MANUAL and QUICKSTART GUIDE.

ABOUT
Select this option to view the current software version and information regarding the Model 15 App.

MODULES
CONTROL PANEL CP-15B
The CP-15B Control panel contains a modified version of the original CP-15 found on the original Moog Model 15 Modular Synthesizer.

POWER
When you launch the Model 15, the red lamp indicates that the power is On. Turn the power switch to Off if you wish to temporarily mute the output of the application without having to change any knobs or connections

TRUNK LINES
In the Model 15 App, Trunk Lines carry audio signals from your Model 15 to the audio
output of your iOS device.

NOTE: The Delay and Recorder module are located after the Trunk Line connections in the audio chain.

NOTE 2: If only one Trunk Line is connected, the signal will be sent to both channels. If both Trunk Lines are connected, Trunk Line 1 will carry the Left signal, and Trunk Line 2 will carry the Right signal.

CONTROLS TO OSCILLATORS & CONTROLS TO ENVELOPES
These switches have been added to minimize patching between a keyboard controller and the Model 15 itself.

Controls To Oscillator [Red switch]: When On, this switch patches the keyboard’s Pitch Control Voltage Output to the Frequency Control Input of the 921A Oscillator Driver. This allows both 921B oscillators to be played in pitch without patching.

Controls To Envelopes [Blue switch]: When On, this switch automatically patches the keyboard’s Trigger signals from the TRIGGER Outputs on the panel to the Trigger inputs on both 911 Envelope Generators.

To bypass these internal connections, simply turn the corresponding switch to Off.

NOTE: The Model 1150 Ribbon Controller does not feature any hard-wired connections, and must be patched from the RIBBON MAIN and RIBBON AUX CONTROLLER OUTPUTS in order
to function

CONTROLLER OUTPUTS
Traditionally, pressing a key (or touching the ribbon) on a modular synthesizer creates a Control Voltage that can be used to determine the pitch of a note played, plus a Trigger signal that can be used to trigger envelope generators. This section has been updated to provide Control Voltage and Trigger outputs from the Keyboard, Animoog Keyboard, and Ribbon controller. Multiple outputs are provided, so you can send the same control signal to multiple locations.

NOTE: For more information on how the Moog Keyboard, Animoog Keyboard, and Model 1150 Ribbon Controller generate the various signals listed below, please refer to the Controllers Section of this manual.

PITCH CONTROL VOLTAGE
These three PITCH CONTROL VOLTAGE jacks each output a Control Voltage based on a note held on the keyboard. This voltage can be used to control the Pitch of Oscillators, or it can be patched to other modules. This allows the key being played to adjust things such as filter frequency, rectangular wave pulse-width, and more. In addition, three TRIGGER jacks are provided which allow you to trigger envelopes when new notes are played.

MODULATION CONTROL VOLTAGE
While the Pitch wheel is permanently assigned to Pitch Bend, the Modulation Wheel can be used to control nearly any module. These three MODULATION jacks each output a Control Voltage based on the position of the Mod Wheel. This signal can be used to open the filter, change the delay time, or change the speed of a modulation oscillator, etc.

NOTE: Incoming MIDI CC 1 messages also appear here.

VELOCITY CONTROL VOLTAGE
These three VELOCITY jacks each output a control voltage based on Key Velocity. This signal can be used to add emphasis to the VCA and VCF, or to change other parameters including DELAY FEEDBACK, etc.

NOTE: Incoming MIDI Velocity messages also appear here.

AFTERTOUCH CONTROL VOLTAGE
These three AFTERTOUCH jacks each output a Control Voltage based on Aftertouch (pressure). Depending on the module this signal is patched to, Aftertouch can be used to control filter brightness, oscillator pitch, etc.

NOTE: Incoming MIDI Channel Aftertouch and Poly Aftertouch messages also appear here.

POLYPHONIC SWITCH
The original Model 15 was by and large a monophonic instrument with duophonic capabilities. With the Polyphonic switch set to On, the Model 15 Application provides four-voice polyphony—essentially allowing you to play four Model 15 synthesizers from one controller. When set to Off, the Model 15 performs monophonically, just as the original.

NOTE: A single voice played in monophonic mode will always be louder than an individual voice played in polyphonic mode. In polyphonic mode, all four voices are summed together, and the volume of each individual voice is lowered to prevent clipping of the audio signal.

RIBBON MAIN
The Ribbon Controller features two independent controllers. The Ribbon itself features a continuous Control Voltage output determined by finger position on the beige colored upper strip, and a light grey lower strip, which sends a Trigger when pressed.

RIBBON AUX
The Ribbon Controller also features an AUX CONTROL slider that sends a second Control Voltage signal available at the Ribbon Aux output.

NOTE: The Ribbon Main and Ribbon Aux Trigger output are both derived from the lower trigger strip on the Ribbon Controller

MIXER
This 4-channel Mixer can be used with audio or control signals. When using audio signals, the mixer can be placed anywhere in the signal chain. Mixing control signals allows you to use different levels of control from multiple sources to provide precise control of any module. There are two sets of outputs. The primary outputs [ + ] are normal; the second set [ – ] is phase reversed, or inverted by 180 degrees.

NOTE: The gain controls on the Mixer can be used to overdrive the input of the mixer itself, or to overdrive other modules like the 904A Filter.

REVERSIBLE ATTENUATOR
The Reversible Attenuator can decrease and/or phase invert signal level. With the knob at center position, no attenuation is being provided. Right of center, attenuation is applied to a signal all until the knob is placed at +10. Left of center, the phase of a signal is reversed and attenuation is applied to a signal until the knob is placed at -10.

MULTIPLES
Two clusters of Multiple jacks are provided. Each one consists of four jacks wired together. These Multiples allow you to insert a signal into any one jack and have it output at the other three. In addition, each multiple can allow signals to be “summed” together into one, although there is no individual gain control for each input.

TIP: Use a Multiple to double a control signal, by splitting it and then sending it twice to the same destination.

OSCILLATORS (VCOs)
Oscillators are the primary sound source of the Model 15. The octave range, semitone, and tuning controls will determine the frequency of the oscillator, while the waveform is responsible for the overall harmonic content of the oscillator output. Oscillators can also be used as modulation sources, especially for other oscillators.

TIP: Changing the pulse width (duty-cycle) of the Rectangular wave from narrow to wide can dramatically change its harmonic content. Control inputs allow the pulse width to be modulated by a control signal, creating PWM (Pulse Width Modulation) effects.

921 OSCILLATOR
SCALE SWITCH
The Scale switch determines the range of the Frequency knob. With the Scale switch in the [±6 OCT.] position, the Frequency knob sweeps the Oscillator’s pitch ± 6 Octaves. With the switch in the [± 12 SEMI.] position, the Frequency knob sweeps the Oscillator’s pitch ± 12 Semitones.

COURSE RANGE SWITCH
This switch selects between SUB-AUDIO and AUDIO settings, making the 921 ideal as either an audio oscillator (VCO) or a low-frequency oscillator (LFO). In addition to the Frequency knob setting, the pitch of the 921 Oscillator is further controlled by the six-position Range dial.

FREQUENCY CONTROL INPUTS
Control signals connected to these three inputs will determine the pitch of the Oscillator in response to a key being played or from a modulation source. The inputs are internally summed into one signal.

WIDTH CONTROL INPUTS
Control signals connected to these two WIDTH CONTROL IN inputs will affect the width of the Rectangular wave, and can create PWM (Pulse Width Modulation) oscillator effects. The Rectangular Width knob manually sets the default width of the Rectangular Wave.

CLAMP TRIG INPUT
The Clamping Point knob is used to determine the retrigger point of the wave cycle, in the presence of a trigger input, which can provide many interesting and exotic effects.

AUXILIARY OUT SECTION
The Auxiliary output section features a six-position AUX OUT WAVEFORM selection dial, with a dedicated Aux Out Level knob, making it easy to use the 921 as a modulation source. Although the two Auxiliary outputs look identical, they’re not; the waveform of the + jack is normal, while the – output is inverted by 180 degrees.

WAVE OUTPUTS
The 921 has dedicated SINE, TRIANGULAR, SAWTOOTH, and RECTANGULAR output jacks, with all of the waves available simultaneously.

921A OSCILLATOR DRIVER
The 921A has no output jacks. Instead, it is internally connected to the two 921B Oscillators, providing master tuning and pulse-width control.

SEMITONE / OCTAVE SWITCH
This switch directly affects the range of the Frequency knob. With the switch in the Semitone position, the Frequency knob sweeps ± 12 Semitones. With the switch in the Octave position, the Frequency knob sweeps ± 6 Octaves.

FREQUENCY KNOB
This knob functions as a master Frequency control for both 921B oscillators. It’s range is determined by the Semitone / Octave switch.

WIDTH KNOB
This knob functions as a master pulse width control for both 921B oscillators.

WIDTH (CONTROL INPUT)
Control signals connected to these two WIDTH inputs will affect the pulse width of the Rectangular wave, and can create PWM (Pulse Width Modulation) effects. The WIDTH OF RECTANGULAR WAVE knob manually sets the default width of the Rectangular Wave.

FREQUENCY (CONTROL INPUT)
Control signals connected to these three FREQUENCY inputs will determine the pitch of the Oscillators in response to a key being played, or from a modulation source. The inputs are internally summed into one signal, but preserve the relative strength of each signal.

921B OSCILLATOR
Each of the 921B oscillators feature four individual outputs, one for each Waveform.

FREQUENCY KNOB
This control is used to offset the pitch of an oscillator by up to ± 12 semitones from the 921A Oscillator Driver setting.

RANGE DIAL
This is a five-octave selector switch with a sixth position (LO) for using the 921B as a Low Frequency Oscillator (LFO).

SYNCH WEAK-STRONG SWITCH
Because Pitch stability is not an issue in the Model 15 app, two new synch algorithms have been added. SYNCH WEAK is inspired by the original Phase Locked Loop behavior. Every difference in phase from the SYNCH IN jack will cause the Oscillator to try to gradually match up to its own phase, thus preserving its own original waveform. SYNCH STRONG implements a traditional hard synch, such that the Oscillator waveforms are reset at each zero-crossing of the input synch signal. The result is a complex, hard-edged sound with a shifting harmonic content.

NOTE: In order for the SYNCH WEAK-STRONG switch to have an effect, you will need to patch any waveshape output from one 921B oscillator into the SYNCH IN jack on another 921B.

A.C. MODULATE & D.C. MODULATE INPUTS
These inputs allow for oscillator Frequency Modulation. Both inputs behave similarly, however the effect of modulation on the D.C. MODULATE input is far greater.

FILTERS
There are two types of filters in the Model 15. The first is a Voltage Controlled Filter (VCF), where the Cutoff Frequency can be controlled by another modulating source. The second type is a static filter that uses settings that remain constant throughout the duration of a sound.

904A Voltage Controlled Low Pass Filter (VCF)
This is the legendary 24dB-per-octave, 4-pole “Ladder” filter, developed by Dr. Robert Moog, that helped to give the original Model 15 its classic sound.

FIXED CONTROL VOLTAGE KNOB
This control is used to determine the Cutoff Frequency of the Low Pass filter.

FREQUENCY RANGE KNOB
This knob specifies the frequency range of the FIXED CONTROL VOLTAGE knob:
1 = (1 Hz ~ 5 kHz)
2 = (4 Hz ~ 20 kHz)
3= (16 Hz ~ 80 kHz)

REGENERATION (RESONANCE) KNOB
This control re-introduces a portion of the filtered sound back into the Filter to create an emphasis peak at the Filter’s Cutoff Frequency. Set high enough, REGENERATION can cause the Filter to self-oscillate, producing a usable sine wave sound source.

FIXED CONTROL VOLTAGE KNOB
These three internally-summed CONTROL INPUT jacks allow the manual setting of the FIXED CONTROL VOLTAGE (Cutoff Frequency) knob to be modulated or controlled by other modules, often one of the 911 Envelope Generators.

923 FILTERS
The 923 features two independent filters; a LOWPASS filter and a HIGHPASS filter. Each filter is equipped with a frequency cutoff knob offering a 10 Hz to 10 kHz range. Both filters provide a 6dB/Octave roll-off either above (HIGHPASS) or below (LOWPASS) the cutoff frequency.

Located at the bottom of the 923 Filter Module are the Noise Source outputs. Noise is useful both as an audio or modulation source. WHITE Noise is bright and ideal for creating wind and pitched percussion effects, while PINK Noise is darker and ideal for creating waterfalls, thunder, and deep percussion effects.

907A FIXED FILTER BANK
The Fixed Filter Bank provides the ability to sculpt the tonal signature of a sound across the entire audio range. In an analog 907A module, each of the eight bands are tied to an individually-wound inductor coil, providing each band with a unique tone. The addition of a LOW PASS and HIGH PASS filter provides additional tone control.

NOTE: If all of the controls are turned down, NO SOUND will pass through the 907A.

TIP: The Fixed Filter Bank cannot be Voltage Controlled in the same way as the 904A Voltage Controlled Filter. However, using the two filters together—either in series or in parallel—can produce outstanding results.

NOTE: ALL of the FIXED FILTER BANK knobs can be assigned to unique MIDI CC numbers.

AMPLIFIERS
Amplifiers are used to boost or attenuate the level of an audio or control signal.

902 VOLTAGE CONTROLLED AMPLIFIER (VCA)
The Voltage Controlled Amplifier (VCA) is a differential (non-summing) amplifier used to boost or attenuate the level of a sound before it exits the synthesizer.

FIXED CONTROL VOLTAGE KNOB
This knob determines the amount of gain applied by the amplifier to a signal.

CONTROL MODE SWITCH
This switch chooses whether the voltage control curve of the amplifier is Linear or Exponential. The setting applies both to the control inputs, and to the FIXED CONTROL VOLTAGE after they have been summed.

CONTROL INPUTS
These internally summed CONTROL INPUTS allow the gain level of the 902 to be dynamically controlled by another module, most often one of the 911 Envelope Generators.

TIP: VCA modules can be used to provide a changing level for any signal passing through them. Try patching the SINE wave output from an Oscillator in LFO mode (LO or SUB AUDIO) into the Control Input of a 902 to create tremolo effects.

NOTE: The signal connected to the upper Signal Input jack will appear 180 degrees out of phase on the upper Signal Output jack, and normal on the lower Signal Output jack. The opposite is true for the lower Signal Input Jack—the upper Signal Output jack is normal, and the lower Signal Output jack will be out of phase by 180 degrees.

AMPLIFIERS (EXTENSION CABINET)
This bonus module contains two summing amplifiers designed to boost the level of an audio or control signal by up to 6 times (much higher than the 902 output). Each amplifier is equipped with two SIGNAL INPUTS, two SIGNAL OUTPUTS, and a level knob.

NOTE: Contrary to the 902 VCAs, the same processed signal is present on both SIGNAL OUTPUT jacks, making these amplifiers useful as Multiples when the level knob is set to 1.

911 ENVELOPE GENERATORS
Reacting to a Trigger from the keyboard or other source, the Envelope Generator creates a control signal whose contour or shape is defined by four controls

T1 (ATTACK KNOB)
The first Envelope stage determines the amount of time it takes for a signal to go from zero to its maximum value after a note is pressed

T2 (DECAY KNOB)
The second Envelope stage determines the amount of time it takes for a signal to go from its maximum value to the Sustain level when a note is held.

T3 (RELEASE KNOB)
This final Envelope stage determines the amount of time it takes for a signal to return to zero after a note is released.

Esus (SUSTAIN KNOB)
Unlike the other three Envelope stages, which are time based, {they're not depending on time, they're based on time} this control sets the constant signal level output of the envelope while a note is held.

Envelope Generators are often used to provide a changing control
signal to the VCA and/or the VCF to add articulation to a sound being played.

ATTENUATORS
Attenuators allow you to lower the level of any audio or control signal. By lowering the knob value, you can apply the right amount of control change to any module or function—or limit the level of any audio source.

955 ATTENUATORS
This module contains three individual attenuators, each with an IN and an OUT. Setting the Attenuation knob to 10 will allow signal to pass at full strength. Rotate the Attenuation knob to the left to attenuate the signal. NOTE: If an Attenuator is set to 0, NO SIGNAL will pass.

TIP: The three attenuators in this module are “normalized” in a descending order. For example, the signal arriving at the IN jack of the first (top) attenuator is sent to the OUT jacks of all remaining attenuators—unless it is blocked by a signal connected to the IN jack of one of the other Attenuators.

REVERSIBLE ATTENUATOR (CP-15B)
This module contains three individual attenuators, each with an IN and an OUT. Setting the Attenuation knob to 10 will allow signal to pass at full strength. Rotate the Attenuation knob to the left to attenuate the signal. NOTE: If an Attenuator is set to 0, NO SIGNAL will pass.

TIP: The three attenuators in this module are “normalized” in a descending order. For example, the signal arriving at the IN jack of the first (top) attenuator is sent to the OUT jacks of all remaining attenuators—unless it is blocked by a signal connected to the IN jack of one of the other Attenuators.

VOLTAGE CONTROLLED REVERSING ATTENUATORS (IN EXTENSION CABINET)
This bonus module is similar to a standard Reversible Attenuator (described above), but with the addition of a Control input jack allowing modulation of the Attenuation amount.

TIP: By connecting audio rate signals to the Control input, interesting effects like Ring Modulation can be achieved.

AUDIO BRIDGE & MIDI BRIDGE

OVERVIEW
The Audio Bridge and MIDI Bridge modules provide patch points that allow the Model 15 to interact with other iOS apps or external devices.

NOTE: The Audio Bridge and MIDI Bridge paths are not interchangeable.

AUDIO BRIDGE
Audio Bridge allows the Model 15 to access—and be accessed by—other audio apps on your iOS device. The From jacks receive audio from other iOS apps or the outside world, allowing the Model 15 to appear as an effect processor in these other Apps. The To jacks send audio to other iOS apps allowing the Model 15 to appear as an audio generator, or sound source. The Inter-App Audio unit labeled Model 15 provides the same audio information that is delivered to the speakers via the Trunk Lines.

The To and From jacks are arranged in pairs. Bus 1 contains Channels 1 and 2. Bus 2 contains Channels 3 and 4. Each Bus features a Mono/Stereo switch. These busses will appear as options when using other Inter-App Audio enabled apps, or through Audiobus.

NOTE: When the BUS CHANNEL switch is set to Stereo, each From port will carry the stereo signal of the Bus over a single Model 15 wire by using two of the internal synth voices. The corresponding TO port will split the signals back out to the left and right audio channels of the Bus. This allows an external stereo signal to be easily connected through a module, like the 904A filter, while preserving the stereo image.

In the MONO mode, each From port carries an independent Mono signal on one voice.

As an instrument or audio source, the Model 15 will appear as Model 15, Model 15 AudioBridge To 1/2 and Model 15 AudioBridge To 3/4.

As an external effect or audio processor, the Model 15 will appear as Model 15 AudioBridge From 1/2 and Model 15 AudioBridge From 3/4.

NOTE: The separate "Using AudioBridge" manual contains more details and will help you get the most out of AudioBridge.

MIDI BRIDGE
The MIDI Bridge module provides six MIDI outputs and six corresponding MIDI inputs. Signals connected to the MIDI To outputs will be sent as MIDI CC Messages. Incoming MIDI CC Messages—will automatically be available at the corresponding MIDI From inputs. Refer to Section 8.3 of this manual for information on how to set the correct MIDI channel and how to choose the appropriate MIDI device(s).

To MIDI outputs:
CC #: 16 – 21
LSB/MSB = Base CC#, Base CC# +32 (16/48; 17/29; 18/50; etc.)
Format: 14-bit MIDI Switch (On/Off)

From MIDI inputs:
CC #: 16 – 21
LSB/MSB = Base CC#, Base CC# +32 (16/48; 17/29; 18/50; etc.)
Format: 14-bit MIDI Switch (On/Off)

DELAY EFFECT MODULE
OVERVIEW
The Model 15 is equipped with a Ping-Pong DELAY EFFECT. Positioned after the TRUNK LINES, the DELAY EFFECT Module processes the entire output of the Model 15.

DELAY PARAMETERS
TIME KNOB
The Time knob determines the amount of delay time applied to the output of the Model 15. There is also a dedicated Control Input for Time allowing it to be modulated.

MIX KNOB
This knob sets the blend between the dry input signal and the effected signal. There is also a dedicated Control Input for Mix allowing it to be modulated.

FEEDBACK KNOB
This knob determines the amount of delay signal fed back into itself. This can result in both longer delay trails and self-oscillation. There is also a dedicated Control Input for Feedback allowing it to be modulated.

CLOCK SYNC SWITCH
When ON, the Delay TIME control is used to determine the BPM subdivision for the Delay Effect. When Off, the Delay TIME is fully variable.

RECORDER MODULE
OVERVIEW
This is a real-time audio recorder with overdub capabilities. Unlimited overdubs can be performed using different Presets to create intricate patterns and performances. These performances are saved to the Buffer Clipboard that can be shared via AudioShare, AudioCopy/AudioPaste, Email or even Text Message as a .wav file.

NOTE: The recorder follows the Model 15 tempo, and is also compatible with Ableton Link.

RECORD BUTTON
This is a real-time audio recorder with overdub capabilities. Unlimited overdubs can be performed Tap the Record button to begin recording. The Model 15 will provide a four-count at the current tempo before recording begins.

NOTE: The white ring around the Record button shows elapsed and remaining recording time.
Touch the Record button again and the recorder will seamlessly switch to Overdub mode. The recorder will continue to loop-record when in Overdub mode until the Overdub or Play/Stop button is pressed.

WARNING: Pressing the Record button will clear anything in the Buffer.

PLAY / STOP BUTTON
Press the Play/Stop button at any time to play back a performance, or to end the recording process. During playback, a white ring will form around the Play/Stop button showing the elapsed/remaining playback time.

TIP: Pressing PLAY/STOP to end an ongoing recording will play it back immediately without activating the Overdub mode.

OVERDUB BUTTON
To manually set the Recorder to Overdub mode, first press the Overdub button (the button will light).

TIP: You can also press the Overdub button at any time during playback.

NOTE: There is no four-count when overdubbing.

BUFFER
The audio recording is temporarily stored in a Buffer. The Model 15 does not save audio data internally, so it must be shared or saved via the Share button.

NOTE: Exiting and restarting the Model 15 will clear the buffer.

COPY BUTTON
Pressing the Copy button will copy the contents of the Recorder and save it to the clipboard as a WAV file. Using AudioShare, AudioCopy / AudioPaste or the General Pasteboard, this file can be saved, renamed, archived, and/or shared.

PASTE BUTTON
Using AudioShare, AudioCopy / AudioPaste or the General Pasteboard, any previously saved audio files in the .wav format and in the general pasteboard can be pasted into the buffer, and played by the Model 15 Recorder by pressing the PLAY/STOP button.

UNDO BUTTON
This button will undo the most recent operation performed in the Recorder module.

NOTE: The global Undo and Redo buttons in the Top Bar cannot be used to undo and redo recording operations.

CLEAR BUTTON
Pressing the Clear button will empty the buffer and erase any content in the Recorder.

SHARE BUTTON
Pressing the Share button allows you to share the audio file currently in the Buffer with other nearby Apple AirDrop users or via Message, Mail, AudioShare and other compatible Apps.

SHARING DATA WITH OTHER USERS
OVERVIEW
Sharing allows you to interact with other Model 15 users, musicians, and friends.


SHARING SAVED DATA
Saved data can be shared directly from a Bank / Preset Tab, by accessing the Save/Load CC Map panel (Settings>Configuration>MIDI), or by accessing the Load tab of the Arpeggiator. In all of these instances, you simply need to swipe left on the name of the Preset, Bank, MIDI CC Map, or Arpeggio pattern and touch the Share icon. Then choose the method you want to use to share the data.

SHARING CURRENT DATA
Tap on the Settings Tab in the Top Bar, and select the Share panel. From the Presets column you can share the current Preset or the current Bank, as well as the current Arpeggio pattern and the current MIDI CC Map. Again, tap the appropriate Share button and select the method of sharing. The file will be sent via the selected method.

SHARING AUDIO DATA FROM THE RECORDER
Pressing the Share button in the Recorder allows you to share the audio file currently in the Buffer with other nearby AirDrop users or via Message, Mail, AudioShare and more.

IMPORTING SHARED DATA
When you receive Model 15 data, the message will contain an icon representing the data.

Click on the icon to show your options. When you copy a Preset, MIDI CC Map or Arpeggio pattern to the Model 15, the data is loaded into the current settings, but not saved. So if someone sends you a Preset and you copy it to the Model 15, you must then save it if you wish to keep it for further use.

KEYBOARD COMMANDS
OVERVIEW
A number of shortcut commands can be accessed from an iOS-compatible QWERTY keyboard. These commands include navigation, Preset selection, zoom, undo and redo, as well as the ability to hide and unhide the current controller.

NOTE COMMANDS
These shortcut commands allow notes to be played on the Model 15 over a six-octave range, and at a variety of different velocity levels. The keyboard buttons can be used to trigger notes on the Model 15. The keys are laid out in a piano-style chromatic scale.


The note duration is fixed at about a half-second. Press the Tab key before playing a note to have it hold. Press the Tab key again to release the note(s).

CHANGING OCTAVES
The available range is six octaves.

Lowering the Octave: Each press of the Z key will lower the pitch by one octave.

Raising the Octave:Each press of the X key will raise the pitch by one octave.

CHANGING THE VELOCITY
In order to audition notes at one of eight different velocity levels, connect a patch cable from the VELOCITY controller outputs to the Control Inputs of the active VCA (and or VCF).

Lowering the Velocity: Each press of the C key will lower the Velocity.

Raising the Velocity: Each press of the V key will raise the Velocity.

 

Yes! An iPad user!
We're very few here.

This app looks really sexy, I just haven't purchased it because I believe to be a lot more flexible at a much lower price with AnalogKit.
I'll likely get it with the next 50% off deal

 

well you certainly broke that one down for us.... post some of your audio sketches with it ?

 

Awesome.
Now you can make a cover of this song,also make sure to get the dance moves right.

 

Sometimes I would like to take a bite out of the apple when I see things like this. I wish Android would GTST and gift us with low/zero latent abilities.

 

This and patterning are my fave apps and yeah studio mux. Ask audio have just uploaded a tutorial series on it. The
Sound quality is insane.

 

A little M15 bass and a Battery kit imported to and banged out on iMPC Pro. Keyword here is "sketch".
Like with a big black marker.

what does that link have anything in common with a moog model 15 besides nothing ?

 

Grasshopper,patience.You have much to learn.

 

so teach me, master

 

I love all these modular style synths .
This one looks very similar to pulsar 900 modular synth which is absolutely amazing at creating sounds with all the cable patching .

 

Agree, it is a great sounding synth for iOS -

 

is there a TL:DR for this?

 

Oh well, a lot of improvements have been promised for years, and low-latency audio on Android is possible today - theoretically.

Who knows, PPG started building their fantastic synths on iOS too and later ported them to Mac by popular demand.
It didn't happen with the other Moog apps though, for years...

 

I haven't seen an official Moog VST plugin for any desktop OS. They have VST editors but those require the actual hardware.

At least I have my Monark.

 

man i hate you guys, i have a 32bit ipad ffs
