Absolutely -
1. Go to the last right button marked global
2. press it
3. use the pages button to get to global # 19
4. It should read load single factory preset ?, scroll that with the + & - button until it reads load all factory presets ?.
5. press 'enter'
There you go - now I'm doing these instructions by memory so I may have missed something like 'memory protect on' which is also in the global section.
Also, there is a quirk with the prophecy, the arp doesn't always sync to other devices, and certainly won't if it is not on (activated).
Sometimes on ebay you can buy a manual.
I hope this helps - PA
