MIDI USB Control Change not working

[Grumpy_Mike]

@scumzilla

Wire.begin(SLAVE_ADDR);
  Wire.onReceive(receiveEvent);

What is this all about? And why does to comment above it say

@scumzilla

// Initialize all the pins as a pull-up input.

When clearly it does nothing of the sort.

@scumzilla

I've used the "controlChange(byte channel, byte control, byte value)" function from the documents, but it seems whatever values I put in here, my different software and devices can't recognize them.

This is because although while you have a controlChange function you never call it so you never send anything. Which is why nothing is ever received.

@Deva_Rishi

Have you enabled CC reception in your host

What host ever requires this to be enabled? This does not make sense.
