I see, however, that all organ patches run through the rotor MFX. when you select a patch that is on slow, and you hit the mod wheel, it changes to fast in the MFX edit screen. This would indicate to me that the MFX "Rotor" has control. Hence, when I make adjustments there, it seems to be straightforward with no wierd effects. I have noticed the percussion improved over stock sounds.
