Looking at this spec, should Tune Request be handled the same way as
these system real time messages? I also noticed Reset is still handled
as a SysEx after your patch. Should it be?

Aside from that, I also noticed an old patch that unfortunately never
got merged:

If you understand this MIDI stuff a little bit, you might be a good
person to review and re-submit that patch :)

Thanks,
