The only way of getting the new software (rev 2) on the FR1 is by sending the FR1 back to Roland after receiving a returns number. They will do the update for no money I believe. The only cost is you sending the FR1 to them. Unless you live next to the Roland returns shop, this may be expensive - they will return it free of charge, but check to be sure - I'm in the UK and this is the situation.
I've not found the sounds yuck yet, with such a variety to choose from. Using the manual you can tweak with a number of settings so the FR1 suits your own personal style - to a limit.
