This will RESET ALL MEMORY to the factory settings!!! Save all Voice and Performance data BEFORE you try this!!!

Power-up while holding 'UTIL' & 'ENTER'. This will display the version. The latest OS is v1.20.

After checking the version, let the machine 'time-out' and return to a 'normal' operating mode. I've been told that this enters the machine into a diagnostic mode, and that damage could be done to parts of the memory that you DON'T want to mess with.

Check The OS Without Losing User Memory

If you can send a sysex string, you can check the OS version, and not 'clean up' the user memory.

Send the exclusive message:

It enters the machine into a test mode, and after it reveals the OS version, it just sits there looking dumb- you'll have to shut it down, then power back up, and the user memory is still intact.

Should I upgrade to the latest OS?

For the most part, all versions run smooth, and there shouldn't be any need to upgrade. I asked YAMAHA about what bugs where fixed in each version of the OS, and I got this official reply. If you find any bugs, feel free to tell YAMAHA (if you can get through to someone who knows what an FS1R is ;) or drop me a line and I'll post it on the Bugs - Wish List page.

If you MUST have the latest OS, it can be upgraded by an authorized service center, for a fee.
