hi,

does anybody know how i can use the internal emu fx (not rfx) as an effect on a mono-output on my e6400 ultra?
i.e.:
i got my kick on sub 1 panned to left, my snare on sub 1 panned to right, and want an effect only on the snare.
i think it should be possible if i used an extra preset for the snare, but i think this is a bit complicated...

is there any possibility to use the fx on single groups or voices in a preset?

thanks in advance! :)
