MIDI Channel Picker:
By @xorome


A JSFX from our very own AS fellow member, @xorome. It was one of those "ask and you shall receive" moments. I was looking for a plugin which could route MIDI signal to a selected channel, so i made a post here, and dude stepped in and was kind enough to share his skills for free, and made me the script. You can read the complete process in here, just wonderful.

Here are some things that are probably more likely to be categorised as "simple and boring", but are absolutely indispensable for me in my day-to-day work.


SWS: ReaConsole

It's not sexy but,

• Sometimes you just reach your goal faster with the keyboard than with the mouse.
• And in combination with the Cycle Action Editor, you can use the Console to create quite complex actions.

rodilab_Color palette

• A very simple color palette - despite many customization options - but the fact that I can dock it vertically next to my TCP makes it very handy for me.

ReaNamer (track-item-region renaming utility) [amagalma & gianfini]

• Seriously, this tool saves me A LOT of time.

SWS: Auto Color/Icon/Layout & Default_7.0_theme_adjuster

• I mainly use Auto Color/Icon/Layout to load layouts based on prefixes in the name. Or to automatically color children based on their folder color.
• The new Theme Adjuster is just great.

"View: Toggle to alternate TCP area width (alternate is zero by default)"

• Need more screen space for arranging and editing? This is your action!

 

MIDI Razor Edits
Original Post: https://forum.cockos.com/showthread.php?p=2839310

(from Forum)

What does MIDI Razor Edits do?

MIDI Razor Edits adds the ability to:

• Select, copy, and manipulate MIDI notes and CC data with the precision of Razor Edits.
• Use workflows similar to REAPER’s native Razor Edits but designed specifically for MIDI editing.
• Stretch, scale, invert, duplicate, copy your MIDI data quickly and conveniently.
• You don't need to change event selection to work with notes and CC data.
• Save time and make MIDI editing more flexible and intuitive.

How does it work?

When the script is active (I recommend assigning it to a key command or a toolbar icon), you can left-drag to create areas over notes and CC lane events. Cmd/Ctrl+drag will let you create several at a time. The script reads your grid-snapping settings out and uses them as the default, press Shift to reverse that setting (to turn snapping off or on). Adding the Option/Alt key will cause your lane to extend to the full lane height (in the piano roll), or to _not_ extend to the full lane height (in a CC lane).

Or you can double-click on some empty space and get a new area encompassing all the data in that lane (full-lane in a CC lane (use Option/Alt to get a free area), only surrounding the notes in the piano roll).

Once you've got an area, you can drag to move it (and whatever is under it) to a new location. Cmd/Ctrl+drag will make a copy. Again, Shift will reverse your snapping setting. Or delete the area (and whatever is under it).

Or you can press Option/Alt and drag on the edges of the area to stretch the contents in time, or scale the contents in value. This doesn't work for all stuff -- velocities and notes are special --, but you'll figure it out.

Or you could double-click on an area to reveal The Widget©™, which will let you scale and tilt stuff along a linear ramp.

Or you can use some keyboard commands to do stuff like invert the contents, delete the area contents, duplicate all selected areas to the right. It's documented in this PDF.

There's a preferences app which lets you assign keyboard commands, change scale/tilt behaviors, etc.

i've using this for a while now, its not complete i beleive, little bit buggy. But the dude has done a good job, its very much needed and much requested feature.

There was another one just like it called FX Device: https://forum.cockos.com/showthread.php?t=263622 but it was bit too much i never used it. But anyway u ca try it https://raw.githubusercontent.com/BryanChi/BryanChi-FX-Devices/main/index.xml
it requires Ultraschall, it will be prompted when u try to open dont worry,

 

This action(s) might be overlooked for most, well atleast for me,
Open Fx on last touched track, there are other actions but they dont float the fx window.

Action: "Track: Open/close UI for FX #1 on last touched track"
"Track: Open/close UI for FX #2 on last touched track"...... so on untill #8 mapped from 1 to 8

To close all the fx windows i always used
"SWS/S&M: Close all floating FX windows" mapped to 0

 

Copy Paste Plugin data by MPL : https://forums.cockos.com/showthread.php?p=2831701 Just like the previous one, much overlooked..

 

Play item or track under mouse until shortcut released:

Action/Script: " az_Play item or track under mouse until shortcut released.lua "

Just does what it says, if u r hovering over a track solos the track and starts playing from the mouse cursor if u r in the empty space or on top in timeline region area it will play everything. U need to set a shortcut, for me alt+n was empty so i assigned to it, if u have Reateam scripts u might have it.

Reateam script repository: https://github.com/ReaTeam/ReaScripts/raw/master/index.xml

Reapack: https://reapack.com/repos

 

Only Daw that you can setup across rooms and channel audio directly through Reastream.
I use this all the time to send Audio over to the Main master Reaper PC with the heaviest plugins to route audio and midi back an fourth.
I control that machine from my laptop with TightVNC so I can change the settings on the plugins if I wish, on the laptop I have Reastream Tracks that match the receiving tracks on the Master Reaper PC. This allows you to not need to install tons of plugins they are only needed on the master Reaper PC ( Main Daw machine).

Another thing you can do is run 2 Reapers at the same time in order to do parallel recording and mixing using the Subnet address as the broadcast so the other Reaper picks it up on the same machine.

I know this is silly to some people but you can not deny the genius of allowing these type of weird setup scenarios.

No other Daw out there is even near this.

 

Reaper is just amazing... when I update ReaPack, are the extensions you previously mentioned automatically downloaded, or not?
The only thing that displeases me is Musical Notation... dude, I simply hate writing anything there...

 

@Mynock to answer this question, no updating reapack doesn't necessarily update all the packages, because 'Reapack' is an extension just like SWS, updating Reapack only updates it to the latest version.
To update the packages u need to synchronize, thats when new packages gets installed or updated. To do this open manages repositories from menu bar on top as u can see i use a custom menu set i dont remember the wr in the default menu this could be, but im 100% sure that its after the action and before help menu. After u open manage repositories window 1 there is an option button down below click it to see different option make sure u have enabled "install new pacakges when Sync.." this way all new packages u have imported on the repository gets updated or if there is new one available it ll be installed automatically. the only down side is u never know whats actually installed, unless u r a super user and check it very often. To disable this behavior u can simply uncheck the option, and manually (method 1) use refresh by right clicking on the repo name, this usually puts an update que, then u can check browse package 3, Check the pic below



on the first column there is an 'i' if there is an update available it shows 'u' heres the icon meanings


(method 2)

When right clicking the repo name there u can see an option in install new package to manually install,



Here is a user guide for Reapack: https://reapack.com/user-guide

But sometimes this usually dont work i dont know y it happens but ithink its mostly because the script is not a part of reateam or the repo is third party and its not properly updating from github. For ex; The Fx modulator linking that i posted here, it doesnt properly update to its latest version, have to manually check, maybe its fixed now or maybe not. We cannot complain because most of these were created by users who are sharing there work that they spent hours in making, Reapers main strength is the user base, Dev make Reaper customizable in turn users share their scripts which exceeds the functionality that the Daw natively has.

Talking about things i dislike in Reaper

My complaints: Reaper still haven't given us the option to change some of the font size, like the FX browser and media browser, one reason being that reaper uses most windows or the OS native settings to make it light and fast. Many req for a subfolder or folder tree = meh, chord track = nil, Session view = naeh.. But when u talk about session view in Reaper, on Reaper forum or reddit, there is always some dickhead some idiot talk about Playtime for Reaper like no one ever knew its existence. I mean i have playtime but its not perfect, unless its integrated into Reaper (native). If that ever happens i ll only need one DAW for everything.. it will simply be amazing. But i still Love Reaper for what it is, it always gives me an option, a way around for every task to do things my way

 

I understand your frustration regarding requests for visual customization and more modern features like a folder tree structure, chord track, session view, and the native integration of Playtime. These would be great additions, and, just like you, I greatly admire Reaper and the freedom it offers to work in a personalized way.

Since I write music, the notation aspect is very important to me, even though nowadays this is somewhat of a "dinosaur" practice. At first, notation in Reaper seemed extremely promising. However, since I imagine it's not in high demand, there haven't been further developments (in short, remains extremely slow in development and focused on fixes and small improvements within the overall MIDI editor ecosystem). In this regard, Reaper falls short compared to Cubase 14, Studio One Pro 7, as well as Digital Performer 11.

This may be one reason why it is not as widely used in film scoring, but it is remarkably lightweight and is steadily gaining popularity among audio designers.

When ever i read this line

on forum or email or on the phone with technical support, my brain immediately calls for this

I don't know much about notation editing, but i guess u meant writing notation is a nightmare in Reaper,

Now its my turn "I understand Ur Frustration"

I came across a script a couple of yrs ago, as it was not useful for my workflow i completely forgot about it, no idea of the author or even its name, untill sterday as i was working, one of the scripts in the midi editor, i went though other scripts from that author and there it was, i dont know if u r aware of this, but may be its useful to u.

"MIDI Transfer - Use other Softwares to edit MIDI to Reaper!"
"This script enable transfer automatic to reaper, in my view making the other software more or less an MIDI editor for reaper!!

How it work?
Every time you export MID from the other software it will get updated and organized (in the tracks you assign each channel) in REAPER. It is really good for softwares that afford different workflows but are good to use with an DAW, like Notation Editors (Musescore, Sibelius, Dorico. Finale….) or softwares like PureData, MAX/MSP etc etc etc..."

Requirements: Reaper v6, JS extension, Sws and Reapack.

Midi Toolkit by Daniel Lumertz

MIDI Toolkit have, currently, 4 main modules that are independent. All modules are dedicated for manipulating MIDI notes separating in different parameters. Some parameters are related to note pitch like Pitch and Interval*. Some parameters are related with the notes position like Rhythm**, Measure Position*** and Groove****. The parameter Length is related to the note length, which shall only change the note OFF position. The Velocity parameter is related to the MIDI Note ON velocity. The 4 modules are:

1) Copy Paste: For coping and pasting parameters. It also can merge between the original version and the pasted parameters. If you are pasting to more notes than your copy then the values will loop around.





2) Rotator: For Rotating the parameters. Left and Right rotate in the sequence order ( so if a sequence of pitches are C, E, G and you rotate right it will become G, C, E. Up and Down rotate by increasing/decreasing to the next/previous value ( so if a sequence of velocities are 10, 127, 55 and you rotate upwards it will become 55, 10, 127.




3) Mapper: Switch the value of every occurrence of a parameter. E.g. in a rhythm sequence 1/4, 1/2, 1/4, 1/2, 1/4 if you switch all 1/4(0.25) to 1/3 it will become 1/3 1/2 1/3 1/2 1/3.



4) Serializer: Apply a series of parameters values to selected notes. Can get the series of parameters from selected notes and change the order.
