Hi all,

I am trying to get multichannel output (to four speakers) using ChucK.

I'm running on a Mac and using a Scarlett 18i8.

I've tried running this test code. SinOsc s0 => dac.chan(0); SinOsc s1 => dac.chan(1); SinOsc s2 => dac.chan(2); SinOsc s3 => dac.chan(3);

3::second => now;

But I get this error.

chuck](VM): NullPointerException: (UGen link) on line[3] in shred[id=1:MULTI]

Any ideas? With thanks, Matthew
