Just an FYI if you have previously downloaded any of my SNES MIDI Remaster Project MIDI files, particularly any released in the past couple of years, I have just discovered that most of my GS percussion assignment SYSEX commands were written with invalid checksum bytes.  Some software will ignore this, so might not cause any issues.  However, I will be going back through all my files and fixing the checksums at some point, and when I do I will upload the corrected versions of each.  I'll follow up here when I do.
