I can see why that would make sense in effort to best mimic a rotary device. For the most part I am switching from 1 type of modulation with a slow speed in bank X:1 to a fast square wave trem in bank X:2. In the first bank preset (1:1) it is chorus, then flange, phase, trem and rotary, respectively, in the next banks.
I set this up because I heard a cool clip of using a square wave trem in solos for sustained notes and wanted to try to mimic that, but the time it takes the modfactor to 'catchup' is making that impossible.
I plan on updating the software as soon as I get the device registration transfered to my account (and track down the correct USB).
