    You're right, I checked the circuit board that I soldered and it was wired to GND instead of VCC. I adjusted the schematic. Adjusting the source code to pull pin 10 to LOW also works of course.

    Check the 'Source code for MIDI to USB adapter with "all notes off" filter', it implements a callback for channel messages:

    note on:
    cm.header == 0x90

    note off
    cm.header == 0x80
    or
    cm.header == 0x90 && cm.data2 == 0x00

    cm.data2 is the velocity, 0 equals to off

    ATmega32u4 based boards are able to present itself as different types of USB devices, such as a USB MIDI device. The UNO does not have this ability, unless you change the firmware of the USB controller or use sth like Hairless Midi. It should be possible I guess, but to my idea not worth the effort because you can pick up an ATmega32u4 based Leonardo or Micro from ebay for just a few US$.
