and i'm sorry, try holding down alt, not ctrl...and then move the mouse up and down, that should increase/decrease the amount of 'virtual' outputs....which you can then route to actual audio channels....whatnot. this seems to work for me, despite what settings you enter in the options menu where you seem to be getting that error. (by the way, i'm using battery in a vst environment...not sure if it's the same in sonar). also, i've found that when i change output #'s, it prompts me to restart the battery plug-in, and then those extra outputs show up.
