JD-990: Using MIDI Messages to Select Modes

Tags: jd-990
At times, it may be desirable to change between Performance, Patch, and Rhythm
modes through MIDI. This can be done using system exclusive messages. Use the
following messages to select each mode:

For Patch Mode:
F0 41 10 57 12 00 00 00 00 00 00 F7

For Performance Mode:
F0 41 10 57 12 00 00 00 00 01 7F F7

For Rhythm Mode:
F0 41 10 57 12 00 00 00 00 02 7E F7

NOTE: These messages require that the unit number of the JD-990 be set to #17.
