PLAY et STOP " Midi Player 1 "

[tsempire]

@tsempire I'll give the solution to those who need it.

1. Copy this code:

// Get a reference to the MIDI processor as MIDI player
const MIDIplayer = Synth.getMidiProcessor("MIDI Player1").asMidiPlayer();

// Get a reference to the transport buttons
const grpTranportBtn = [Content.getComponent("btnPlay"),
Content.getComponent("btnStop")];
for(b in grpTranportBtn)
{
// Make sure the buttons are not saved with the presets
b.set("saveInPreset", false);

// Assign the control callback to the transport buttons
b.setControlCallback(onTransportBtnControl);

}

// Also set the STOP button to be momentary
grpTranportBtn[1].set("isMomentary", true);

inline function onTransportBtnControl(component, value)
{
// get which button triggered the callback
local index = grpTranportBtn.indexOf(component);

// If it's the PLAY button
if(index == 0)
{
	// if the PLAY button is pressed
	if(value)
	{
		// start playing
		MIDIplayer.play(0);
	}
	else
	{
		// keep the button's value to 1 if it's still playing
		grpTranportBtn[0].setValue(1);
	}
}
// if it's the STOP button
else
{
	// only react if the mouse is clicked (not released)
	if(!value)
		return;
	
	// stop playing
	MIDIplayer.stop(0);
	// set the PLAY button's value to 0
	grpTranportBtn[0].setValue(0);
}

};

// on compilation, reset the playhead position to the beginning
// comment it out if not needed
MIDIplayer.setPlaybackPosition(0.0);

2. Create 2 buttons with the ID

btnPlay

btnStop
