MIDI Controller with Analog Multiplexer 4051

That's an MIDI Controller for multiplexed analog input based on the analog multiplexer chip 74HCT4051. In that example I use one with 16 knobs, but that could be easily expandeed. The chip selection (pin E) on the 4051 should be used (it's not implemented in that example).
Additional to the two boards one need the PS202 - MIDI-Duino.
