Digital i/o two (4067 Mux) 61 keys

[DrewMidi2022]

Hi. is there a version or a sample code that has a digital i/o for multiplexers (4067) goal is to do a basic 61 keys midikeyboard. can't seem to find the matching codes from the codes.

61 keys 8x11 scan matrix 2 (4067 multiplexers)

// Your code here

#include <Control_Surface.h>
#include <Arduino_Helpers.h> // Include the Arduino Helpers library
#include <AH/Hardware/ExtendedInputOutput/AnalogMultiplex.hpp>
