Simple Envelope - release not working

[Lindon]

OK I have a drum sound in a sampler - with a simple envelope attached to manage GainModulation - the Attack works fine - but the release doesnt work at all.

I suspect this has something to do with the fact I am triggering note playback in my Samplers midi processor - on note call back thus:

function onNoteOn()
{
    Message.ignoreEvent(true);
    Synth.playNote(Globals.triggerNote, Message.getVelocity());
    Console.print("playing trigger note:" + Globals.triggerNote);
}

I suspect here that this is because there is no corresponding note off event for my script triggered play_note. Do I need to keep the play_note noteID in some Global(again) spot and issue a note off for it? Or is there some other way in the note off I can get to the id of my internally triggered note?

I guess I'm thinking of KSP play_note(some note, some velo, some offset, -1)

Where "-1" means "releasing the note which started the callback stops the sample"

@Lindon I don't see a need to use a global to create the note off (unless you need to turn if off in another script) just a reg variable should be fine. If you want 1 ID per note then use a MIDIList instead.

function onInit()
{
    reg noteId;
}

function onNoteOn()
{
    Message.ignoreEvent(true);
    noteId = Synth.playNote(Globals.triggerNote, Message.getVelocity());
    Console.print("playing trigger note:" + Globals.triggerNote);
}

function onNoteOff()
{
    Synth.noteOffByEventId(noteId);
}

Another option
