Thank you for the kind words and inspiration!!! using the last channel for CV would be great in this combo!

I cite from the squarp website:

4 dedicated audio outputs (mono, DC-coupled = can play CV signals) [-5V to +5V]

I'll need a nice way to create DC wav files now! I've played with PD but I'm not super efficient with it (if one can be, who's not autechre)

I'll keep you updated.
