I was wondering if the jv-1010 had leslie effects for the organs? Can You hook up a pedal and control the speeds, or possibly program a button that will do that? Or is this not possible. Also how are the stock organ sounds?

I believe the JV-1010 has a configurable EFX effect called "rotary" that imitates a leslie. In theory, you could assign an external controller to manipulate it. Of course, you'll have to figure out how to do all this, which I've not been able to yet. But it's in the docs.
