Music Controller with 126 Knobs





Nine multiplexers with fourteen pots per multiplexer. Data sent over 126 MIDI CCs. The code is easily expandable to 256 pots (i.e. 16 x 16).

Sorry if you've mentioned this elsewhere, what are the 16-channel analog multiplexer boards you are using here? I'd like to do a 16- or 32-step sequencer with pots, computer keyboard toggle switches, and LEDs.

Hi there!
This is the type of multiplexer with breakout board:

However, I grabbed some for about $2.60 per unit, FYI!
