Hi DKLAK,
On the 2000 you can only have 1 voice for the lower split> you can have layered voices for right. BTW do you like your 2000 other than that? I had one but returned it because it was not saving any of my settings also some of the LED`s would "flicker" when they were turned off. And I had a "hiss" comming from the speakers, even at min. volume.
