Can anybody please confirm that the DRIVE effect (the variation of the EFFECTS section to the right, not the VALVE DRIVE to the left) is mono?
I set up a nice effect-laden Rhodes (E.PIANO part, TINE variation 9) which has a built-in tremolo - as all EPs do - that is especially spacey here; it is more of a pan effect than a tremolo. If I engage the DRIVE effect, the stereo collapses into mono, which is not a problem in itself, but the spaciousness of the pan/tremolo is gone, of course.
The other effect types do not seem to exhibit this behaviour.
