I also spent a few days troubleshooting this new circuit, since the solenoid was always activated. After some tests, it turned out to be a bad MOSFET (and a bad replacement one, too). They were failing the most basic test and passing current between the gate and source.

Now that I’m back in business, it’s time to switch from an Arduino Uno to a Teensy, which can function as a USB MIDI instrument!
