Marvelous uses an raspberry pi pico 2 (rp2350) in the form offered by Olimex (Bulgaria) This provides all 8 ADC pins since ALL rp2350 pins are broken out. There is a qwiik/stemma port to allow extending the device, as well as unpopulated pins you could hack.

All controls are via 4 encoders, the meta and parameter encoders, though a number do double duty. See the how-to for details.

The DAC used is a PCM5102a module, running at 16 bit, 48kHz. Inexpensive but reliable.
