Control velocity from each incoming midi note with a Knob / Slider?

[Rognvald]

I know it is possible to link a button to incoming each midi note.
Can the same be accomplished with a Knob for each note?
( controlling the velocity while the note is being pressed )
I often do this in Max/Msp, PureData.

Thanks I hope :)

@Rognvald Do you want the knob to set the velocity or the velocity to set the knob value?

[Rognvald]

@d-healey Ahh, the Knob to control the Velocity

@Rognvald

Ok let's say your knob is called knbVelocity and you have a reference to it in onInit

const knbVelocity = Content.getComponent("knbVelocity");

In the onNoteOn callback you can use the knob's value to set the Message's velocity.

Message.setVelocity(knbVelocity.getValue());

Ideally this should be done using two MIDI processors. The Interface script should be deferred - which means you won't be able to use setVelocity there. A second MIDI processor should be used for setting the velocity, and the knob on the GUI should be connected the knob of the second MIDI processor.

@d-healey Ok thanks for all this info, I will have a blast and see what comes out :)

@d-healey I am currently using this code for buttons to midi. Is there any way to insert this velocity function or would I also need to put this code on the second Midi Processor? Little confused but I am sure it can work.

onInt

const Buttons = Content.getAllComponents("Button");

//	this list will save the played note eventIds
reg eventIds = Engine.createMidiList();

//	this played keys will trigger the buttons
reg keysThatTrigger = [48, 49, 50, 51];

//	this notes will sound 
reg triggeredNotes = [48, 49, 50, 51];

inline function onButtonsControl(component, value)
{
	local index = Buttons.indexOf(component);
	
	if (value)
		eventIds.setValue(triggeredNotes[index], Synth.playNote(triggeredNotes[index], 60));
	else
		Synth.noteOffByEventId(eventIds.getValue(triggeredNotes[index]));
};

for (b in Buttons)
	b.setControlCallback(onButtonsControl);

onNoteOn

function onNoteOn()
{
	Message.ignoreEvent(true);
	
	if (keysThatTrigger.contains(Message.getNoteNumber()))
	{
		local index = keysThatTrigger.indexOf(Message.getNoteNumber());
		Buttons[index].setValue(true);
		Buttons[index].changed();
	}
}

onNoteOff

function onNoteOff()
{
	if (keysThatTrigger.contains(Message.getNoteNumber()))
	{
		local index = keysThatTrigger.indexOf(Message.getNoteNumber());
		Buttons[index].setValue(false);
		Buttons[index].changed();
	}
}
