no, you're not understanding what i'm talking about. not a hardware synth, like a keyboard or something. a software synth, reason's Maelstrom or FL's Sytrus. ok, sytrus would be easier than maelstrom, but you get the picture. the whole point is doing everything - drums, bass, pads, everything - using different instances of the same synth.
edit: yeah, zircon, that's what i'm talking about. like Blue v1.01, for example - that kind of stuff.
