Just go get the Z1!!!!! Even it's plucked and wind structures sound better than the Prophecies. Yes the factory presets are different but you can much more easily program a Z1 from the front panel and it has so much more in terms of real time control.
Yes the Prophecy has the cool mod log bender but the Z1 had the fantastic XY ribbon controller.

If you only need monophonic sounds, save you bickies and get the Prophecy but REALLY, you can get that and MUCH MORE by simply paying extra and getting the Z1!!!!!

PS- as you can see, I really like my Z1! Cheers. Korgasm.
