I think Prism is oen of my favorite reactor instruments. I tried the free version for player and it caused me to upgrade. Nothing sounds like it. It makes these organ pluck and hammer sounds, strange digeridoo drones and such and it all sounds like a real acoustic instrument from another planet! Like moon men playing their moon xylophones or something. Its such a cool instrument. Just nothing else like it. I could try to talk about the features and how it works but I don't even get it entirely. its one of those few pieces of gear I just fiddle with at random until magic happens.... like programming a DX7 from scratch. A lot of unpredictability because of the bizzare architecture. There's probably a manual for it but whatever.
