Hello,

I'd like to upgrade the EEPROM content in my GEM PRO2 to the latest version 1.07 (550635/G). Mine dates back to 1998. It would be awesome if someone could share the BIN or HEX.

Sometimes the original version it sends something funky via MIDI if not in the LOCAL OFF mode. It seems that some MIDI problems and key release were fixed in the latest version.

Thank you !

Latest release? Didn't GEM go bankrupt?

Well, the latest release that they did before going bankrupt. 😄

I have no idea where to find a one.

(One company did eventually buy all their IPR but I don't know what's their status at the moment. It's been quiet...)

Hello,

Actually the last version 1.07 dates back to year 2000. It seems quite rare. I.e. there are plenty of instruments, but they don't fall into the hands of engineers with EEPROM programmers often wink

To be more precise, the content of EEPROM 27C4001 ver 1.07 (550635/G) from week (or month) 10 year 2000 is badly needed. This is the only EEPROM in this instrument.
