Also, it depends which keyboard the registrations are from?
Murray is quite correct (obviously, since he made YRM!), as all CVP's are backwards compatible, as long as you convert to 709/609/509 etc it will work on 809. In other words, if you change a registration to target CVP309, that registration *will* work on all subsequent CVP's. With 1 weird exception (CGP1000). For some reason, while CVP409 and earlier can be read on CGP1000, CGP1000 reg's *cannot* be read by any other CVP (which is odd since it's the same chipset as CVP409... why change the reg file?)
*However* not all sources are available (DGX670, PSRA5000, and while Genos registrations work up to 2.02, I don't know if anyone has checked to see if there are any differences in the header of a reg file from Genos 2.10, so that might also not be compatible)
