Well, I use 2 channels, so I can keep the dry signal, but it's still in unison playing the same notes.
Now, if the Future Impact can add in some randomness, then that's no bad thing.
But if you are having to do a dance on the pedal you might as well go for a Taurus or something; The Keith McMillen 12-Step allows you to assign 5 notes to each pedal.
