Editing the Config

Each button is capable of a short and long presses on each page.

To customize the MIDI note or control change transmitted, the midi-stomptroller.ino file must be edited and flashed to the Arduino.

To change the function edit the MIDI.sendControlChange(); or MIDI.sendNoteOn(); lines for each button and page.

MIDI CC's for the Helix Stomp are listed here on page 49.

Example

Below we change the long press for Page 1 Button 2 so that it recalls Snapshot 3.

Diff

//Page 1
    case 1:
      Serial.write("Button 2 Page 1 Long \n");
-     // FS5
-     MIDI.sendControlChange(72, 127, MIDI_Base);
+     // Snapshot 3
+     MIDI.sendControlChange(69, 2, MIDI_Base);
      break;

Before

void button2LongPressStart() {
  switch (page) {
    
    //Page 0
    case 0:
      Serial.write("Button 2 Page 0 Long \n");
      
      // FS5
      MIDI.sendControlChange(72, 127, MIDI_Base);
      break;

    //Page 1
    case 1:
      Serial.write("Button 2 Page 1 Long \n");
      
      // FS5
      MIDI.sendControlChange(72, 127, MIDI_Base);
      break;
  }
  setBlink(neoButton2,2);
}

After

void button2LongPressStart() {
  switch (page) {
    
    //Page 0
    case 0:
      Serial.write("Button 2 Page 0 Long \n");
      
      // FS5
      MIDI.sendControlChange(72, 127, MIDI_Base);
      break;

    //Page 1
    case 1:
      Serial.write("Button 2 Page 1 Long \n");
      
      // Snapshot 3
      MIDI.sendControlChange(69, 2, MIDI_Base);
      break;
  }
  setBlink(neoButton2,2);
}
