custom System Exclusive messages - dwhinham/mt32-pi GitHub Wiki
mt32-pi responds to MT-32 SysEx messages as you would expect, but it can also respond to its own commands. mt32-pi listens for manufacturer ID 0x7D, or the "non-commercial/educational use" special ID. Therefore, a complete mt32-pi SysEx message looks like:
F0 7D { command } { parameters } F7
Take a look at the System Exclusive utilities page for examples of utilities you can use for sending these messages.
⚠️ Note: These commands are subject to change until the project reaches a mature state.
