...you mean, as distinct from the familiar chorus effect using either tapin/out or allpass? I haven't used Reason in a while but I seem to remember finding the rack effects a bit, erm, grungy - apart from the high end reverb though. But then my ears are a bit knackered.
Most of the effects are kinda crappy but the thing about this is I
can't hear it granulating or modulating as much as other choruses when I crank it.
You actually inspired me to run a sine wave through it. I'm thinking
that the taps are all running out of phase. (Ok i should have thought
of that) Usually when I crank a chorus I get that up down roller
coaster effect. Ill try it later.
