onNoteOn || Trigger UI Button with Midi Note?

[d.healey]

@Chazrox Nearly.

References to components (and modules) should only be created in on init and stored in aconst.

Within the MIDI callbacks you should use local instead of var - in general, never use var unless it's the only choice.

Message.ignoreEvent(false);

This isn't needed, Messages are not ignored by default.

You can shorten this too if you want:

n == 60 ? Button1.setValue(1) : Button1.setValue(0);

to

Button1.setValue(n == 60);

@d-healey alllmost! ha. Thanks.

@d-healey said in onNoteOn || Trigger UI Button with Midi Note?:

Button1.setValue(n == 60);

so slick.

[Chazrox]

@d-healey this isnt triggering the button. Is there a step I might be missing somewhere else? This is on the main interface script onNoteOn. Its triggering a sinewave generator right now but I plan to delete the sinwave generator and just use it as a midi player. 1 note/chord player.

[d.healey]

@Chazrox If you want to trigger the button's action you need to call the .changed() function after setting the value

[Chazrox]

@d-healey that works but I get stuck notes. Im trying to achieve a while-key-down effect. Im rewatching your "While Key Pressed" video but I dont think thats exactly what I need. What should I be looking for as far as apis?

[d.healey]

@Chazrox what does your button do?

[Chazrox]

@d-healey my button is triggering a chord. I have everything scripted out and it works fine with mouse clicking the button. Just need the '1-note' part to work.

this is what my buttons callback looks like. ugly...but for some reason this works best for my use.

//! CHORD 2 BUTTON CONTROLS
inline function onButton2Control(component, value)
{
	local Chord2Choice = cmbChord2.getValue();
	local chord2 = ChordLibrary[cmbChordType2.getValue() - 1];
	local Octave2 = Knob2.getValue() * 12;

	
	if (value)	
	{
		eventId3 = Synth.playNote(chord2[0] + 72 + Octave2 + Chord2Choice - 1, 64);
		eventId4 = Synth.playNote(chord2[1] + 72 + Octave2 + Chord2Choice - 1, 64);
		eventId5 = Synth.playNote(chord2[2] + 72 + Octave2 + Chord2Choice - 1, 64);
		eventId14 = Synth.playNote(chord2[3] + 72 + Octave2 + Chord2Choice - 1, 64);
		eventId16 = Synth.playNote(chord2[4] + 72 + Octave2 + Chord2Choice - 1, 64);
		eventId17 = Synth.playNote(chord2[5] + 72 + Octave2 + Chord2Choice - 1, 64);
		eventId18 = Synth.playNote(chord2[6] + 72 + Octave2 + Chord2Choice - 1, 64);
		
		Engine.setKeyColour(chord2[0] + 72 + Octave2 + Chord2Choice - 1, SetKeyColour);
		Engine.setKeyColour(chord2[1] + 72 + Octave2 + Chord2Choice - 1, SetKeyColour);
		Engine.setKeyColour(chord2[2] + 72 + Octave2 + Chord2Choice - 1, SetKeyColour);
		Engine.setKeyColour(chord2[3] + 72 + Octave2 + Chord2Choice - 1, SetKeyColour);
		Engine.setKeyColour(chord2[4] + 72 + Octave2 + Chord2Choice - 1, SetKeyColour);
		Engine.setKeyColour(chord2[5] + 72 + Octave2 + Chord2Choice - 1, SetKeyColour);
		Engine.setKeyColour(chord2[6] + 72 + Octave2 + Chord2Choice - 1, SetKeyColour);
	}
	else
	{
		Synth.noteOffByEventId(eventId3);
		Synth.noteOffByEventId(eventId4);
		Synth.noteOffByEventId(eventId5);
		Synth.noteOffByEventId(eventId14);
		Synth.noteOffByEventId(eventId16);
		Synth.noteOffByEventId(eventId17);
		Synth.noteOffByEventId(eventId18);
		
		Engine.setKeyColour(chord2[0] + 72 + Octave2 + Chord2Choice - 1, NoKeyColour);
		Engine.setKeyColour(chord2[1] + 72 + Octave2 + Chord2Choice - 1, NoKeyColour);

		Engine.setKeyColour(chord2[6] + 72 + Octave2 + Chord2Choice - 1, NoKeyColour);
	}

};

Content.getComponent("Button2").setControlCallback(onButton2Control);

...12 Buttons mapped over 1 octave.

@Chazrox You need to trigger the button in the note off callback in addition to note on

[Chazrox]

@d-healey I must have wrote a funky code because I tried some stuff on onNoteOff but it was not off'ing. lol. Can you give me an example of that line please?

and theres a weird 'Blip' sound upon triggering my chords now.

can I pm you this snippet?

[d.healey]

@Chazrox just the same as you have in the note on yes.

[Chazrox]

@d-healey Sorry I made a mess in your inbox.

[d.healey]

@Chazrox You filthy bugger :p
