MIDI system exclusive message
A dump of all memory and current settings.
Initiated from the front panel UTIL screen.
The archiving device must be ready to receive data
when the dump is initiated.
The front panel and MIDI input is inactive during the
duration of the dump.
Replaying a dumped file over a MIDI link to an icon
with the same MIDI channel number as in the file
will cause the data to be restored.
A successful restore will overwrite the current
settings and all memories including those ‘locked’.
The icon will reboot after a successful restore.
Any detected error in the MIDI message stream or the
data will cause the restore to be aborted and leave the
icon unchanged. An error message is displayed.
Message format:
Sysex header:
F0, 00, 00, 1A, 50, 07, MV, Mv, 0c
MV = major version number 0…127
Mv = minor version number 0…127
0c = current MIDI channel number 0…15
The header is then followed by a Sysex ID byte:
Sysex ID = 00 (dump header)
followed by F7 (end of Sysex)
Sysex ID = 01 (data packet)
Followed by:
<Packet #> …0 …127 (wraps around)
<Byte Count> …encoded data bytes – 1
<Data> 7 bit encoded data
<ChkSum> One byte (XOR of all bytes
following F0 to the checksum byte)
F7 (end of Sysex)
Sysex ID = 02 (dump end)
Followed by F7 (end of Sysex)
Further details of the way the data is encoded is
available in the MIDI 1.0 Detailed Specification
Version 4.2.
