=====  MIDI Controller with Analog Multiplexer 4051 =====
----
That's an MIDI Controller for multiplexed analog input based on the analog
multiplexer chip [[http://www.ti.com/lit/gpn/CD74HCT4051|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 [[arduino_boards:midi-duino|PS202 - MIDI-Duino]].\\
