The Prophet Rev 2 looks really cool I've been reading the manual. I have two Tetras I use in various ways, and I think the Rev2 can do almost everything that they can do. I use the tetras in different ways, sometimes with my Mopho keyboards to extend the voices to 5. But, you can also layer programs on the tetra, so I will use it with (the mopho) to stack patches. Lately I have had it set up in series in multimode giving me 8 sequencers and a midi looper. I do all percussion and rhthym on one and the other is for melody and harmonies. So, I have been very happy with my setup. But, the Rev 2 can do some thing interesting things that this can not. Even if I don't have sysex I can always start with a Prophet 08/mopho patch and fine tune the NRPN, so it wasn't a huge problem but still, I do use the sysex data when designing sounds. On my moog little phatty, allI can do is randomize the CC controllers as a starting point. I can do that with Mopho/Prophet 08 too, but it's easier if I can just load sysex and then apply meta patch as starting point.
