drum kit arduino mega 2560

Hello, my name is Sylvain, I am in the objective to create an drum kit midi wicht arduino mega 2560.
I need you, because I try to use my pedal of sustain, to close my hi-hat. I have to find on your forum a code, but I try to add it the swicht.
Could you help me?
Exemple: (A0, is my hi-hat...)

Thank you!

#define MAX_PIEZO 9

uint8_t piezo[MAX_PIEZO] = { A0, A1, A2, A3, A4, A5, A6, A7, A8 };
uint8_t drumType[MAX_PIEZO] = { 9, 8, 7, 6, 5, 4, 3, 2, 1 };

const int threshold = 500;

void setup()
{
for (uint8_t i=0; i<MAX_PIEZO; i++)
pinMode(piezo*, INPUT);*

  • Serial.begin(57600); *
    }
    void MidiTX(unsigned char StatusByte, unsigned char Note, unsigned char Val)
    {

  • Serial.write(StatusByte);*

  • Serial.write(Note);*

  • Serial.write(Val);*
    }
    void ProcessPiezo(uint8_t p)
    {

  • uint16_t sensorReading = analogRead(piezo[p]);*

  • uint16_t val;*

  • if (sensorReading > threshold)*

  • {*

  • uint32_t oldcas = millis() + 5;*

  • // this part of the code looks complex*

  • // explain what you are trying to do?*

  • while (analogRead(piezo[p]) > threshold)*

  • {*

  • if (millis() >= oldcas)*

  • {*

  • val = analogRead(piezo[p]) / 9;*

  • }*

  • }*

  • MidiTX(144, drumType[p], val);*

  • MidiTX(128, drumType[p], val);*

  • }*
    }
    void loop()
    {

  • for (uint8_t i=0; i<MAX_PIEZO; i++)*

  • ProcessPiezo(i);*
