I just finished assembling a Pepper kit I bought last year. There’s a rev 2 that has audio outputs with an amplified signal from an added op amp. The nice people at Queen Mary University of London mailed me an adapter board free of charge because I bought a rev 1 before the rev 2 was released.
Anyhoo…I’m into the possibility of at least getting monome serial devices to work on Bela. There’s only a single USB host port but it could be interesting to port some of the code from monome eurorack modules to a Pepper’d Bela. I’ve always been intrigued by the demo videos of Ansible. I think it’d also be a thing to make Bela versions of some Mutable Instruments code.
