Err... what?

Battery doesn't come with FL... or did you add the VST?

Panning in Piano Roll is as simple as changing the drop-down box in the bottom left to Pan and then adjusting the graphs. Maybe I misunderstand the question though.

look above, Ive changed something. hope its clear now coz english isnt my primary language

as far as i know, the parameters in the bottom of the piano roll (vel, pan, pitch ,etc.) only work with the fruity plugins...unless of course, you assign one of those parameters to control whatever you want. (like with z3ta+ you can assign the vel to control the main output or whatever you wish)

Battery 3 reportedly doesn't work well with FL 6. I haven't heard about the panning problem in the piano roll, but I have heard that if you have more than one instance of battery, the samples will start canceling each other out.

I dont have fruity, but it sounds like what your altering with that dropdown menu might be midi messages, I think you need to add an automation track or something like that. Hope that clears it up...
