i added a line in the code and its working properly now i think, is there any other way of implementing this in your code?
void MyHandleNoteOn(byte channel, byte pitch, byte velocity) {
if(pitch == 62)
note62playing = true;
else
otherNotesPlaying++;
if (note62playing && otherNotesPlaying == 0)
MIDI.sendPitchBend(-2949,channel);
else
MIDI.sendPitchBend(0,channel);
if (pitch == 62)
MIDI.sendPitchBend(-2949,channel);
}
