You could try the one here http://dsiforum.com/download/file.php?id=1551 worked with the beta so probably fine for the release version. Also make sure to set some delay between sysex messages in whatever tool you are using to send the file.
Thanks Bob. The .syx file doesn't come with any instructions - do I simply fire the data at my Pro12 just like an OS update?
Hi Howard!
Nice to see a Facebook friend here
Yes, as far as I remember (it's five months since I downloaded and installed the AltTunings1-16_17May2015.syx file), you just send it like an OS update.
Before you get TOO excited though, the various tuning options are sadly a global setting, rather than saved with each program, so you have to select the appropriate tuning by hand each time you want to revisit a particular non-equal-tempered program
