if you reverse the polarity of a switch you get... the same switch!!!
so no change...

Walter,
The VK-8M responds to MIDI messages from 0-127 on CC80, where 0=slow
and 127=fast. If you use a regular sustain pedal, when the pedal is
up, it looks like a 127 to the VK-8M, so you get fast leslie. When
you step on the pedal, you send a 0, which slows the leslie -- but
only as long as you've got the pedal depressed. If you reverse the
wiring on the pedal, all you did is reverse the effect -- normally
slow, fast when you step on it.

Instead of a sustain pedal, use an expression pedal, such as the EV-5
or EV-7. That'll give you a continuous sweep from 0-127... Which is
actually kinda cool, because you can vary the leslie speed anywhere
between the fast and slow speeds...

Hope that makes sense...
