The Rev2 can definitely get experimental…It’s really up to you. 4 LFOS, 8 mod slots, a third assignable envelope, two different kinds of sequencers, arp…You can kind of just go wherever you want.
Guess it depends how you define experimental. One of my first synths I learned synthesis on was a Novation Bass Station II and I made some fairly experimental sounds that my friends complained hurt their ears. I was quite proud of them lol. Most synths these days are probably more capable than a BSII.
No, it doesn’t have FM or AM or wavetable. If you want newer kind of sounds I would look at the Hydrasynth desktop. Actually, for my money, a Hydrasynth desktop costs about $400 less than a Prophet Rev2 desktop and personally I would go that route. Like if I had to decide between the two. I was actually deciding between the two keyboard versions a few months back and went with Rev2 because they’re comparable in price and I decided I wanted an analog synth–not wavetable–just because I’ve never actually owned an analog synth. Not that I care about that whole debate! I love all synths! But I still wanted my very own analog with a nice keyboard for myself.
EDIT: I’m going through sold listings of the ASM Hydrasynth desktop and a used one can go from $600 to $700 which is an insanely good price…That comes out to almost half the cost of a Rev2 8-voice desktop. I know you said you wanted something knobby, but from what I’ve heard about the Hydra, everything you want to reach is just a click away.
