Expression pedal ( Boss FV500H ) in Performance Mode

[volante]

I've got a Boss FV500H and I can't find a way to have the right control.
Anyone with this pedal? How do I set lateral volume?

First thing: you can assign the channel to the control pedal in system menu. Standard setting is cc11, could be nice changing it on some other channel to have a stand alone control.
Sysctrl1 how do you use that?

In patch mode it's quite simple, you assign parameter control in matrix and you're ok.

I've got some problem in Performance Mode, I'm trying to set MFX control, but I can't find any way to do that.
For example, you've got 2 part one with a tremolo organ, one with a rocky organ, and you would like to have control on the rocky organ ROTARY volume or speed.
How do you do that?

I think there's something very wrong in the pedal expression control, because you can't really control.
It would be nice and simple having a simple parameter, where you can choose what control pedal do.

Thanks for your help and excuse my poor English...

Anyone??
If you don't understand what I wrote because of my bad English, please can you tell me HOW do you control a Leslie speed effect with an hammond patch (or, better, with a performance)?

thanks
