APPENDIX C
SYSTEM EXCLUSIVE MESSAGES
In addition to the MIDI program and controller change messages described earlier in this
manual, the X-15 also sends and responds to MIDI system exclusive (SysEx) messages.
This section requires an basic understanding of MIDI protocols and the hexadecimal
numbering system. How you actually send and receive SysEx messages is beyond the
scope of this manual.
The X-15 SysEx messages are used to set/get operating parameters, determine the
presence of the X-15 in a MIDI network, and to verify reads and writes to the X-15’s EEPROM.
The general form of an X-15 SysEx message is:
The <func> byte defines the SysEx message type. For the X-15, there are six possible <func> bytes,
as expressed in the following table.
