Can a multiplexer handle more than one type of input<control surface.h>

You can have multiple muxes, but putting them through a single channel would probably invoke more complexity than you want - especially if you’re asking this at the outset.

It’s quite easy to implement a mux for each type of input signal, and will make it much easier to check parameter limits, and otherwise filter and control the various sources.

Thanks for your time, what you said, was my experience so far. Putting one signal type per mux worked without a hitch, but when I assigned the different functions of button and potentiometer, neither worked.

#include <Control_Surface.h>

USBMIDI_Interface midi;

// Instantiate an analog multiplexer
CD74HC4051 mux = {
  A3,       // Analog input pin
  {2, 3, 4} // Address pins S0, S1, S2
};
CCPotentiometer volumePotentiometers[] = {
  {mux.pin(0), {MIDI_CC::Channel_Volume, CHANNEL_1}},
  {mux.pin(1), {MIDI_CC::Channel_Volume, CHANNEL_2}},
  {mux.pin(2), {MIDI_CC::Channel_Volume, CHANNEL_3}},
  {mux.pin(3), {MIDI_CC::Channel_Volume, CHANNEL_4}},
};
  CCButton button1 [] =  { 
  {mux.pin(4), {MIDI_CC::General_Purpose_Controller_5, CHANNEL_4}},
  {mux.pin(5), {MIDI_CC::General_Purpose_Controller_5, CHANNEL_5}},
  {mux.pin(6), {MIDI_CC::General_Purpose_Controller_5, CHANNEL_6}}
   };
