setup:
	set the pinModes to INPUT for reading;
	creating the data arrays for storing the values of the pots and buttons;
	begin the Serial transmission for MIDI at 31250 bauds;
	set the CD4051 to 0;

loop:

			val := read the value of the switch or pot;
			if (val != the value stored):
				update the stored value;
				send the Midi Message corresponding the control and value
