Any reason that CVPal can't be reprogrammed as a dual channel 12-bit DC coupled soundard for use with the likes of M4L and Bitwig CV tools? It'd be a lot cheaper than the Expert Sleepers solution.
It uses a cheap MCU with no USB support. USB is bit-banged, takes almost all of the CPU, and only supports low-speed transfers.
Thanks Olivier. Thought there'd be a good reason.
Bit-banging. Nice. Old Skool.
