Hi John
I have an early US version and I managed to get in contact with the software designer Michel Doidic but he could not help me with this issue. I have made some hardware changes that Michel suggested (Replaced some resistors) but that did not change anything. My Xpander is at my techie guy now and I really hope he can fix it.
I did find some other website with the latest OS (ROM files) but the checksum was wrong.
I wonder if anyone here has successfully upgraded their Xpander with (ROM files) found on the Internet ?
Cheers / Tobbe

Hi Tobbe,
The Europa upgrade is for your Roland Jupiter 6: http://www.synthcom.com/Europa/europaFaq.html
As for your strange (but cool) tuning sounds, I'd call that a feature rather than a bug. ;) I don't know why it started doing that, but it does raise the issue of OS versions matching/requiring specific circuit board revisions. Perhaps you have a particularly early/late board version? Other than that, some slight corruption of the EPROM containing the firmware is the only other possibility I can think of offhand.
Cheers,
John :^P> 2012/4/3 John Pallister <john@... (mailto:john@...)>

If not, could he be persuaded to donate the source code to the Xpander user community (i.e. this mailing list)?
