Hi, I'm a KSP newbie and probably I'm doing something really stupid... I'm using Kontakt 5.8 engine, full version, trying to develope a simple instrument.

Every time I play a note (on note event) I'd like to have a custom knob that can visually display the current velocity value in order to give the user a visual feedback of the intensity of the played note (just for fun and aesthetics )

It might be a custom knob that represents a speaker, so by playing a keystroke hard (high velocity) I could show a beautiful kind of animated speaker icon with different image size and aspect in accordance with the velocity value. It should be nice effect to look at, especially when you play along with rhythm, IMO.

what I can't understand is why I can make it work if I write

$VelocityStandardKnob := $EVENT_VELOCITY where $VelocityStadardKnob is the simple built-in standard knob that Kontakt offers, in that scenario when I play a note I can see the knob reflect the velocity value but if I switch from the built-in knob type and use a custom knob with custom graphics instead (you know, it's a slider in reality), then that custom knob does not reflect the velocity value when I play a note.

I have put a message instruction after the assignment and I can see that the $VElocityCustomKnob value contains the same current value of the $VelocityStandardKnob value so I am really stucked ... what I am doing wrong ?

Thanks a lot guys, for you support.

 

Users already have an integrated sensor for detecting velocity… it's called ears… focus on sound, not on gimmicks!

 

Example code for a three-state slider:

File structure:

Code:

Instrument.nki
res.nkc
res.nkr
Resources\pictures\button0.png
Resources\pictures\button0.txt

button0.txt (notice the empty line at the end, the file should be 10 lines exactly):

Code:

Has Alpha Channel: no
Number of Animations: 3
Horizontal Animation:  yes
Vertical Resizable: no
Horizontal Resizable: no
Fixed Top: 0
Fixed Bottom: 0
Fixed Left: 0
Fixed Right:  0

KSP:

Code:

on init
    set_ui_height_px(150)

    declare ui_slider $slider0(1, 127)
    set_control_par_str(get_ui_id($slider0), $CONTROL_PAR_PICTURE, "button0")
    move_control_px($slider0, 250, 0)

    declare $vel
    message (" ")
end on

on note
    ignore_event ($EVENT_ID)
    $vel := $EVENT_VELOCITY

    if ($vel >= 100)
        $slider0 := 100
    else
        if ($vel >= 50)
            $slider0 := 50
        else
            $slider0 := 1
        end if
    end if
end on

Dude, relax. He's not a user in this, he's the developer, a beginner one. His question is totally legit. At least read what the thread is about.

Edited:

Almost forgot: great answer. Bravo
