Hi

Im developing a USB-MIDI musical project using the Teensy 3.2. I have wrote a very basic program that plays a middle C in Musescore when I press a button on my electronic circuit that is connected to the Teensy board.

My question is, when I send a ubMIDI send program change to musescore, to change the instrument type, this has no effect and Musescore continues to use the Default piano instrument.

Could you explain if this is in fact possible, or am I doing something incorrect with my code, see below code:

include // Bounce library makes button change detection easy

include // MIDI Library

const int channel = 1;

Bounce button1 = Bounce(1, 5); // 5 = 5 ms debounce time, which is appropriate for good quality mechanical pushbuttons

void setup() {
pinMode(1, INPUT_PULLUP);
}

void loop() {
button1.update();

// Note On messages when each button is pressed
if (button1.fallingEdge()) {
usbMIDI.sendNoteOn(72, 99, channel); // 60 = C4 //usbMIDI.sendNoteOn(note, velocity, channel)
usbMIDI.sendProgramChange(65, channel);
usbMIDI.sendPitchBend(50, channel);
}

// Note Off messages when each button is released
if (button1.risingEdge()) {
usbMIDI.sendNoteOff(72, 0, channel); // 60 = C4
}

// MIDI Controllers should discard incoming MIDI messages.
while (usbMIDI.read()) {
}
}
