Hello. My name is Josie Hill and I've been involved in MIDI since the mid 1980s when I wondered what those sockets were on the back of of my Roland JX3P. Roland Japan would not supply me the format of the MIDI memory map dump from a Roland TR707 drum machine because they opined it would be too hard for me to understand! However, I managed to reverse engineer it.

Now, 30 years on, I have a similar problem with the first version 1.1 Fender Cyber Twin PS-393. Can anyone please supply me with the format of the 55 byte data block per preset?

So my interpretation, so far, of the SYSEX dump data:
00007D8C 1 -- F0 Buffer: 6 Bytes System Exclusive
SYSX: F0 08 21 11 02 F7
00007E76 1 -- F0 Buffer: 55 Bytes System Exclusive
SYSX: F0 08 21 11 02 00 01 2A 00 43 68 61 6D 70 20 27 00 34
SYSX: 39 20 20 20 20 20 05 20 20 24 0C 40 42 71 0B 40 7F 7C
SYSX: 48 28 73 68 00 00 00 7F 7F 7F 7F 00 00 00 00 00 00 01
SYSX: F7
00007EC4 1 -- F0 Buffer: 7 Bytes System Exclusive
SYSX: F0 08 21 11 02 7B F7


is:

File start: {F0 08 21 11 02 F7}
Data header: {F0 08(<- start of checksum) 21 11 02 00}
Data Checksum: OK
Data trailer: F7
File end: {F0 08 21 11 02 7B F7}

Hi Josie,

I'm trying to convert some parameters of a single preset to CC using StreamByter.
I only have a basic knowledge of this Midi Magic and I'm trying to identify the description and values for the dial readings in the "dump"

Your posts here have given me some hope and a starting point. Where did you end up with this?

Cheers,

Greg
