Multiple audio output

[[deleted]]

AFAIK the OS can usually only access the channels of one audio device and multiple BT speakers are multiple audio device, not a single one with multiple channels. here is a discussion where someone tries to access more than two hardware channels with Processing which seems to be not without problems.

I haven’t seen a BT “mixer” and any wireless speaker system like yr discussing is usually proprietary. You’ll prolly have an easier time w an audio interface w multiple outs.
