Chord memory function with basspedal and midi-shield

Using Arduino Audio

Hello, perhaps it's the right thing!

What is to do? Combine ?

Like this or is something to change?

#include <Button.h>
#include <MIDI.h>

#define DEBOUNCE 1500

struct key
{
int pin;
int midiKey;
int debounce;
};

struct key keys[] =
{
{ 22, 25, 0 }, // Db red
{ 24, 26, 0 }, // D red
{ 26, 27, 0 }, // Eb orange
{ 28, 28, 0 }, // E orange
{ 30, 29, 0 }, // F yellow
{ 32, 30, 0 }, // Gb green
{ 34, 31, 0 }, // G green
{ 36, 32, 0 }, // Ab blue
{ 38, 33, 0 }, // A blue
{ 40, 34, 0 }, // Bb violet
{ 42, 35, 0 }, // B violet
{ 44, 36, 0 }, // C brown
{ 48, 24, 0 }, // C brown
{ 0, 0, 0 } // end of list marker
};

    noteOff(keys.midiKey);
    }
    else // Key has not gone off*
    keys*.debounce = DEBOUNCE; // Reset debounce counter in case we got*
    * // a small number of key off scans*
    * }
    }
    }*_
