What I have tried in the past is run one pd for audio and another one for
GEM stuff, which worked rather well.
I wonder if it would make sense to do the same with 2 pd instances doing
audio, and exchange audio between them.
Maybe I could try that with Jack.
But I think the latency will be doubled, because the buffers of both pd's
would add up...?
