Tone.Draw

↳ EXTENDS Tone
SINGLETON

Tone.Draw is useful for synchronizing visuals and audio events. Callbacks from Tone.Transport or any of the Tone.Event classes always happen before the scheduled time and are not synchronized to the animation frame so they are not good for triggering tightly synchronized visuals and sound. Tone.Draw makes it easy to schedule callbacks using the AudioContext time and uses requestAnimationFrame.

CONSTRUCTOR

new Tone.Draw ( )

EXAMPLE

Tone.Transport.schedule(function(time){
	//use the time argument to schedule a callback with Tone.Draw
	Tone.Draw.schedule(function(){
		//do drawing or DOM manipulation here
	}, time)
}, "+0.5")
