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?

Well, can't find any mention of a CyberTwin PS-393.

I do find a CyberTwin PR-393, this is a Guitar Amplifier, and yes, it does have some midi functions, incl a data dump There are details in the manual for the format of the Preset, although while you say this is 55 bytes, the detail I see shows 12 bytes only, although the doc I've seen has the full details for those 12 bytes, namely what each of the items is, and what all the options for each are, and there is a clear example of the SYSEX command to implement the settings.

So, there's some sort of mix up somewhere. Are there other varieties of CyberTwin, is the PS-393 something quite different?

Oh, the device I was looking at is specifically a CyberTwin SE. The 'PR-393' is not mentioned. I just happened to see on the pic of the rean panel hat it said PR-393.

Yes, it probably WAS too difficult for you to understand. Probably too difficult for ANYONE to understand, unless you were a computer scientist working for Roland! They are better now, they're discovered the value of a few examples of real world use of SYSEX, although sometimes they aren't perfect.

If you have the manual for your whatsit, this OUGHT to have the midi map, so if you have a spare weekend you might try to make sense of it. I have enough of my own whatsits, so I've not bothered with your Fender thingie, which may well be even more complicated than the midi map. Otherwise I'll have to try and find the midi manual on the web, and try and make sense of it via html,

But hopefully, someone here might have such a device, with the manual, and be able to quote you the details ;)

But, being a nosey blighter, I just might check the web abyway.
