Hi ron,
No sweat. I thought I'd try it because I don't use that module so much, anyways, so I didn't mind loosing data. I have been able to reset it, no problem and even upload the original SySex (ah, those 80's memories). I even have some of my own sysex dumps somewhere in the backup CDs.
Anyways, at least the linux community knows now that cat x.mid >/dev/midi doesn't really work. I would assume that editing the dump file (generated via cat /dev/midi >dump) into correct sequences of SySex messages and sending them sequentially (via a script?) might still work.
On a related note, I noticed (a while ago) that I have been unable to record a sysex dump to a MIDI sequencer (I tried MuSe and perhaps seq24) and then play it back into the unit (I mean I can record and play but I always get checksum errors). Other people's SySex in .mid format works for me. It could be that it's my synth sending erroneus SySex. I haven't really looked into it in detail.
This is still with a Roland GR-50. I know that some of the D series models had a bug with checksum calculations. If anyone has any idea about this, let me know. But it's no rush. I would have forgotten all about this if it wasn't for this thread. I guess I can blame Ron for reminding me of my old problems :)
cheers.
