2022-01-26 (W) EWC_Panel A few small tasks

Even though I watched it function before, my SOLO port wasn't working with the synthesizer. I grabbed a USB↔MIDI converter and plugged it into the same synth, which worked, so I will not worry about this issue for now. The next time I build a circuit like this, I will include a diode to reduce reverse-polarity noise. I improved my note playing function to stop old sounds without starting new ones. Ceasing notes needs to happen if I switch chords, octave, channel, melody, length, or generate a new prandom arrangement. This isn't an issue in many instruments, but it could "hang" sometimes and play something continuously. Next, I made it possible to change instruments from the panel, so when I see "Acoustic guitar" on the screen, the synth will play that instrument.
