Synth.sendController() crash

[d.healey]

This code causes a crash. I'm not sure if I'm meant to have called something like getSampler() first and used the sampler variable instead of Synth. if so how should I send a controller message to all samplers - would it be another use case for the new helper function perhaps?

Content.setHeight(150);

const var Knob = Content.addKnob("Knob", 277, 34);
// [JSON Knob]
Content.setPropertiesFromJSON("Knob", {
  "text": "Mod-Wheel",
  "max": 127,
  "stepSize": "1",
  "middlePosition": 64
});
// [/JSON Knob]

function onNoteOn()
{
	
}
function onNoteOff()
{
	
}
function onController()
{
	
}
function onTimer()
{
	
}
function onControl(number, value)
{
	if (number == Knob)
	{
		Synth.sendController(1, value);
	}
}

Ah yes, I forgot a safe check... It's fixed now (Synth.addVolumeFade() was also crashing).
