Hi uzi_hs
The input / output ranges of Pepper are as follows:
- 2 audio in (AC-coupled, 10V pk-to-pk (-5 - 5V), 44.1kHz, 16bit)
- 2 audio out (DC-coupled, 10V pk-to-pk (-5 - 5V), 44.1kHz, 16bit)
- 8x CV in (DC-coupled, 0-10V with pots attenuating, 22.05kHz, 16bit, 12V safe). Optionally, up to 4x of the CV in sockets can be swapped for trigger ins, leaving the pots connected directly to Bela's analog inputs.
- 8x CV out (DC-coupled, 0-5V, 22.05kHz, 16bit)
There's also a bit more info on the voltage divider and matching resistor values for the perfect input range here: https://github.com/BelaPlatform/bela-pepper/wiki/Notes-on-choosing-resistor-values
Add to that that these are mapped to the full range from the Bela inputs / outputs 0.0 - 1.0
