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,
