<![CDATA[Transposing MIDI Player Based On Incoming Notes]]>So i have just figured out the simple way to have a single key trigger the midi player, however i would like to devote an area of the keybed to the midi loop and have the coinciding note transpose the midi player. Ex. Range Note 0-24 Root =Note 12. Giving the ability to transpose the midi melody up or down one octave.

This works fine with corresponding noteoff message to make it stop..i have it at 36 for testing. but want it 0-24 with 12 root and up and down transposing based on the pressed key

function onNoteOn()
{
	if(Message.getNoteNumber() == 36)
    {
        var timeStamp = Message.getTimestamp();
        MIDIPlayer1.play(timeStamp);
        Message.ignoreEvent(true);
    }
}

What do i need to do to achieve this? I would also be connecting a button to enable and disable this processing and behave like a normal keybed

declaring the midi modules in oninit

const var MIDIPlayer1 = Synth.getMidiPlayer("MIDI Player1"); 
const var Transposer1 = Synth.getMidiProcessor("Transposer1");

then i have to manually add the note range i want to trigger with transpose

function onNoteOn()
{
	if(Message.getNoteNumber() == 36)
    {
        var timeStamp = Message.getTimestamp();
        MIDIPlayer1.play(timeStamp);
        Message.ignoreEvent(true);
        Transposer1.setAttribute(Transposer1.TransposeAmount, -1);
    }
    if(Message.getNoteNumber() == 37)
        {
            var timeStamp = Message.getTimestamp();
            MIDIPlayer1.play(timeStamp);
            Message.ignoreEvent(true);
            Transposer1.setAttribute(Transposer1.TransposeAmount, 1);
        }
}

then the noteoff messages

{
	if(Message.getNoteNumber() == 36)
    {
        var timeStamp = Message.getTimestamp();
        MIDIPlayer1.stop(timeStamp);
        Message.ignoreEvent(true);
    }
    if(Message.getNoteNumber() == 37)
        {
            var timeStamp = Message.getTimestamp();
            MIDIPlayer1.stop(timeStamp);
            Message.ignoreEvent(true);
        }
}

i KNOW there is a much more efficient way to achieve this...however im not good with arrays and indexes. and i wouldnt be mad if someone optimized this code for 0-24 with note 12 root :) but as of now it works lol
