Bounce Audio Sample

[oskarsh]

Hey, I would like to Bounce a audio sample from my AudioLoop Player with all the effects.

I think I need to use Engine.renderAudio(eventList, callback); however I am not so sure how I can create a single MIDI Player.

How can I trigger a single midi note and render the Audio?

@oskarsh create an array with two message holders, one note on and one note off and pass that into the function as eventList.

@Christoph-Hart I got the Audio to render however I am still wondering how someone would go about dragging this audio to a DAW? Can you share a minimal example or guide me into the correct direction with this?

inline function createEventList()
	{
		local events = [];
		
		local on = Engine.createMessageHolder();
		on.setType(1);
		on.setChannel(1);
		on.setVelocity(127);
		
		on.setNoteNumber(60);
		on.setTimestamp(0);
		
		local off = Engine.createMessageHolder();
		off.setType(2);
		off.setChannel(1);
		off.setNoteNumber(60);
		
		local numSamples = 24516;
		
		off.setTimestamp(numSamples/8);
		
		events.push(on);
		events.push(off);
	
		return events;
	}
	
	inline function onRender(obj)
	{
		local isFinished = obj.finished;
		
		if (isFinished) {
			Console.print('DRAG TO DAW NOW');
		}
	}
	
	inline function renderAudio()
	{
		Engine.renderAudio(createEventList(), onRender);
	}

@oskarsh in the render finished callback, pass on the rendered buffer to a scriptpanel (save it in its data object). Then in the mouse callback on click, write the buffer to a temp file, then use this method:

(docs.hise.audio)

(You might have to write the file in the render finished callback because it might start lagging the drag, but you‘ll see).
