So I am thinking about buying a Dave Smith Instruments Evolver, which is an analog synth module. I don't have a lot of experience with analog stuff, but i really need some super fat sounds for what I am working on. Has anyone ever used one of these, or any other DSI synth? The only analog synth ive played was a moog little phatty, which was awesome but a little out of my price range. Also, I don't need another keyboard because my current setup already requires 3. Any other advice/ information about analogs that would help me out?
