I dug back into the data transmission issues and set the data to known values. Most of the time, MIDI resources will display commands in hex. I referenced an ASCII chart and changed my code to send capital letters. They didn't transmit correctly. I changed the example code to send even more characters, but that didn't work.
I checked my results with a MIDI ↔ USB adapter reading the data port and PuTTY checking the data off the USB ↔ serial converter connected to the Arduino, but it was all garbage coming out. When I changed the baud rate from 31250 to 9600, I received what I expected, and I could even crank it up to 115200bps with no fidelity loss. When I swapped out the USB converter, I finally got good data at the MIDI standard baud rate, which solves one problem and confirms that the hardware can transmit at the unusual rate.
