Pisound Micro can’t be stacked with another Pisound Micro or Pisound, but it could be stacked with Pimidi’s.
Eurorack audio levels should be good to go for Pisound Micro.
Is it possible to add two more stereo in/out to use as send/return for an fx loop?
Hey, it has multiple output and input ports, but internally, they all mix into a 2 channel stereo mix in the codec.
