Just about everything is modulatable by any CC. The synth also contains 4 LFO's, and 4 envelopes. The filters can be set up in many different configs, the same as the FM routings. I love this synth. Future Music gave it a fairly shit review but after reading it, I have come to the conclusion that the guy who wrote it is a bleedin' fool and never actually tried to learn the synth. He even went so far as to say that it was not trully multitimbral, yet I make it respond to at least 4 channels for every song I write. (It will go to 16, I have tried it.) For the money, $495, and for the upgrade options, (all upgrades are free for download) this synth is WAY worth it.
Comments About the Sounds:
The FM sounds are extremely cool, as you can filter them with 2-8 pole lp, hp, bp (x2), and notch filters.
