So my quesion is this: how do send audio to different sound devices from pd? I see in the "Test Audio and Midi" patch that you can send audio to different channels with [dac~ 2] or [dac~ 3] , so is this all i need to do in order to get it to work?
This, and you have to start pd with a list of the soundout devices you want to use like
$ pd -soundoutdev 0,1
starting from 0 as usual.
i did some archive searching and came up with this:
from IOhannes m zmoelnig about "pd-patch for (better) multidevice support"
This is already included in PD 0.35 since at least test17.
I see another problem with your setup, and that is the hardware side. If you use several consumer soundcards without synchronization instead of a decent multichannel card, it might or probably will happen, that your audio will run out of sync. This means: the samples you send synchronized from the PD DSP-chain will come out of the four soundcards at different times, because each of the soundcards has a different understanding of absolute time because of slight differences in their clock chips.
Depending on the things you do, this might be nasty, *especially* if your installation is running for a long time, because your audio data will differ more the longer it can run out of sync. Maybe stopping audio in PD from time to time could help.
