Ok... it seems that ChucK support for multiple outputs varies depending out what audio interface you use. I'm on a Mac too by the way. The only thing i can think of is to try out various settings, for both --in --out and --adc/--dac (it's possible that there is some other number you need to use for --adc, since 7 didn't seem to work). Perhaps someone here with some insight in the ChucK implementation and audio drivers in general can offer some insight. I know that I had to do a bit of trial-and-error until I found the sweetspots where my outputs actually work.<div>

Yes. For my MOTU soundcard it took a bit of tinkering to get it right. Here's an example of a command line:<div><br></div><div>chuck --adc4 --in4 --out8</div><div><br></div><div>This means that I'm using device number 4 (adc), with 4 inputs and 8 outputs.</div>
<div><br></div><div>After that you can write like this in you ChucK app:</div><div><br></div><div>SinOsc s => dac.chan(3); // send sine wave to the fourth mono output</div><div><br></div><div>Note that you'll have to take care of stereo if you want it:</div>
<div><br></div><div>adc.chan(0) => LPF filterLeft => dac.chan(0);</div><div>adc.chan(1) => LPF filterRight => dac.chan(1);<br><br></div><div>The tinkering bit with MOTU is that all combinations of numbers of inputs and outputs don't work. For instance --in3 --out8 will have the whole thing go bananas, with weird sound being outputted. If you don't use a MOTU card there's a good chance you won't have this problem.</div>

Hi, I've a sound card with 8 outputs (4 left and 4 right) and I want to send different audio signals to each output.<div><br></div><div>Is this possible with chuck?</div><div><br></div><div>Thanks<br clear="all"><br>
