I'm the happy owner of a JV-1010 and I've got one problem: how can I choose the the type of effect for my EFX without using sysex? Or is that impossible without using sysex? Or does someone know where to find sysex-messages for changing the effect?
Someone told me that it should be possible to change the effect by using the controllers.

I would be very happy if someone could find me a solution.
