Okayyyyyyy, i think i have something now.
Hearing the cops coming with a loop :wink:

/*
So simple midi
*/

int speed_com = 31250; // the midi speed
int note;

    
void setup(){  
  Serial.begin(speed_com);     // init serial speed
  playMidi (0x90, 0x5A, 0x45); // play on channel 1, never ending pain of my ears !
}

void loop(){

  // NOW, PITCH ME, PLEASE !!!
  for (int i=2000 ; i < 8000 ; i+=5){
    // you're under arrest, cops are singing !
    PitchWheelChange(i);
  }

}

void playMidi (int cmd, int pitch, int velocity) {
  Serial.write(cmd);
  Serial.write(pitch);
  Serial.write(velocity);
}


// johnwasser was here !
// Value is +/- 8192

void PitchWheelChange(int value) {
    unsigned int change = 0x2000 + value;  //  0x2000 == No Change
    unsigned char low = change & 0x7F;  // Low 7 bits
    unsigned char high = (change >> 7) & 0x7F;  // High 7 bits

   playMidi(0xE0, low, high);
}

I'm not sure where i'm going with that, but i'm learning !
I think i'm gonna try adding a potentiomer to drive your function.
If someone looking for me, i'm in the lab !

Thanks for France :smiley:
