Hello guys! first post here.
I am working on a simple midi controller with one button. Everything is perfect sending the cc message to Ableton (on/off).
Now I am using this function to receive the value from Ableton (0/127) every time that I press the button in Ableton.

void cc_message(byte channel, byte control, byte value) {
  switch (control) {
case 21:
Serial.print("button feedback: ");

As far I know, Teensy only receives the value if I press the button in Ableton. Is there any way to receive the value automatically when I connect Teensy to USB?
