SuperCollider AnalogOut not working. Bela Gem Multi

Ricardx_sg

I've been trying to use AnalogOut, but when I run the following code, I get the following error:

AnalogOut Error: the UGen needs BELA analog outputs enabled

But I don't know what that means. Am I using AnalogOut correctly?

s = Server.default;

s.options.numAnalogInChannels = 8;
s.options.numAnalogOutChannels = 8;
s.options.numDigitalChannels = 16;

s.options.blockSize = 16;
s.options.numInputBusChannels = 2;
s.options.numOutputBusChannels = 2;

s.options.postln;

s.waitForBoot({
	
	SynthDef(\writer, {
		AnalogOut.ar(0, 0.5);
	}).add;

	s.sync;

	a = Synth(\writer);
});

ServerQuit.add({ 0.exit }); // quit if the button is pressed

There's no analogOut on the Gem Multi, just 10 audio outs. So you should be able to use those via the normal audio out bus (I didn't test this, but that's how it's meant to be). Note that channels 2 through 9 are DC-coupled with an output voltage range of ±5V, so if you send positive values they will behave similarly to the analog outs of the Bela cape.

Oh, that makes sense, thank you so much for replying.
