If you like romplers you'll like ravity. The style of editing feels very much like sitting with a JV1080 and an editor/librarian app. The UI appeared a bit fiddley and imprecise at first, but after reading the manual I found out that there are several ways to enter data, and then everything was all right. Though its not a tricky synth to use, giving the manual a quick look is recommended. (There are some grammatical errors in there though.)
I gave the presets an 8. They are quite good, but a bit limited in their range, and I dont think they demonstrate the full capabillities of ravity.
The selection of waveforms is great and so is the sound quality. I havent spent more than about 8 hrs actually editing yet, but so far I am 100% happy with what Ive heard.
You can use 2 oscilators per layer, and a maximum of four layers so there is definatly room for complex sounds. The arpeggiatior is like they usually are, but since you can use different arp settings on each layer you can create pretty nice stuff.
Its easy to lose track of time playing with this baby. Its intuitive and inspiring to use.
Bang for the buck.. well, its pricey no doubt but it also has the potential to be a real workhorse(its very easy on the cpu). Personally I feel that I got more than my moneys worth, but I also feel that its exactly what I have been waiting for so I am clearly biased.
