@Lindon Not when I made the plugin. I installed ipp with the export wizard after.

tried to export to VST from HISE standalone and all I got was

Press any key to continue . . .

@David-Healey An issue I run into now is when

function onNoteOn()
{
	
for (note in track) {
	if (note.isNoteOn()) {
		Console.print(note.dump());
	    Console.print("Note: " + note.getNoteNumber()); 	
	    //Synth.playNote(note.getNoteNumber(), note.getVelocity()+1);
	    //Synth.playNote(note.getNoteNumber()+12, note.getVelocity()+1);
	    //Synth.playNote(note.getNoteNumber()-12, note.getVelocity()+1);
	}	    				      
		//Synth.noteOffByEventId(note.getEventId());
	}    	
}

function getNoteOn(list, noteOn)
{
    for(note in track)
    {
        if(note.isNoteOn() && note.getEventId() == noteOn.getEventId())
            return note;
    }
}
MIDIPlayer1.flushMessageList(track); 

I uncomment any of the synth.playNote function calls, it plays very distorted, notes playing for far longer than they are supposed to, like I mentioned earlier.

@David-Healey

As an aside: I plan on exporting this to Ableton, so eventually the plugin will load MIDIs from DAW tracks.

@David-Healey

Content.makeFrontInterface(600, 600);
const lookAndFeel = Engine.createGlobalScriptLookAndFeel();
const var MIDIPlayer1 = Synth.getMidiPlayer("MIDI Player1");
const var track = MIDIPlayer1.getEventList(); // The notes to be transposed up 1 octave


/* Grab note, create second harmonic of note
playing at same time of it
O(n) complexity
*/
Console.print("-------------------------------------");
for(note in track)
{
    if(note.isNoteOn()) {
	    
    
	    Console.print(note.dump());
    	Console.print("Before: " + note.getNoteNumber()); 
   
    	//note.setNoteNumber(note.getNoteNumber() + 12);
    	Synth.playNote(note.getNoteNumber(), note.getVelocity());
    	Synth.playNote(note.getNoteNumber()+12, note.getVelocity());
    	Synth.playNote(note.getNoteNumber()-12, note.getVelocity());	    				      


	    Console.print("After: " + note.getNoteNumber()); 
	     
    }  
}
// 3. Flush the processed list back to the MIDI file
MIDIPlayer1.flushMessageList(track);

@David-Healey Ok, so

    if(note.isNoteOn()) {
	    
    
	    Console.print(note.dump());
    	Console.print("Before: " + note.getNoteNumber()); 
   
    	//note.setNoteNumber(note.getNoteNumber() + 12);
    	Synth.playNote(note.getNoteNumber(), note.getVelocity());
    	Synth.playNote(note.getNoteNumber()+12, note.getVelocity());
    	Synth.playNote(note.getNoteNumber()-12, note.getVelocity());	    				      


	    Console.print("After: " + note.getNoteNumber()); 
	     
    } 

The issue now is whenever I click Compile, it always hangs on the first note, never going to the second. I have to turn off the synth module to get it to stop. What's the fix? I'm a beginner here, so I'm in need of help with this lol

@David-Healey Got it. Would it be possible to play the note in the track, plus the 2nd harmonic at the same time?

Like, it would play the note's 2nd harmonic at the same time without writing it to the track?

Given a MIDI track, I want to write a function such that it takes the note at a given position, creates its 2nd harmonic note at the same position, and places the note at the same position in the track.

How would I go about doing this?

Here's a basic transposer I have written so far. It doesn't copy the notes, it just moves them up an octave.

for(note in track)
{
    if(note.isNoteOn()) {
	    
    
	    Console.print(note.dump());
    	Console.print("Before: " + note.getNoteNumber()); 
   
    	note.setNoteNumber(note.getNoteNumber() + 12);	    				      


	    Console.print("After: " + note.getNoteNumber()); 
	     
    }  
}

@d-healey Fixed, thanks!

I'm new to HISE so I'm bound to do beginner mistakes lol

When I create a script reference, I get the errors:

Script FX1:! Line 1, column 38: Unknown function 'getEffect' {U2NyaXB0IEZYMXxvbkluaXQoKXwzN3wxfDM4}
Prototype:! Line 1, column 38: Unknown function 'getEffect'!!!!
