[chuck-users] Multichannel Mono Output using ChucK (Matthew.Noone)

[Nunn, Douglas]

Note that in v1.3.4.0 here's a bug in parsing the --dac flag. I don't know if this has been fixed in a later version. (I have to use this version as there's an ASIO build.)

Use --dac_1 or --dac01 to fix this.

The trick here is you also have to tell ChucK to be 4 channels.
>From the command line:

chuck -c8 YourFile.ck

depending on what your —probe shows, you might even have to
specify which dac (and adc) to use, especially if they’re different
device numbers or channel numbers.  Also, might need to up the
buffer size to avoid clicking, especially for lots of channels.  Examp:

chuck -c8 -bufsize2048 -in2 --dac1 --adc0 YourFile.ck

Hope this helps,

PRC

PS:  If you’re using MiniAudicle, then you need to do some menu stuff to
pick output/input devices, and numchannels as well.
