I upgraded to lion, installed new apogee duet s/w and drivers. When I load a logic project, I uncheck the s/w monitor button, but the maestro 2 mixer screen does not have the button under the s/w return faders to enable low level mixing. No mic audio is being sent to the headphones when the logic s/w monitor button is unchecked. System press and logic press show duet enabled for in and out. Anyone know why that button is missing from my maestro mixer screen or in general how to get low latency mixing enabled using maestro 2. My maestro 2 panel also does not show headphone controls like it shows in the manual. I suspect a WH or driver problem because I also can't get my acoustic guitar into instrument 2 connection on the duet. I hope I'm instead having a senior moment and I am just forgetting to do something easy. Frustrating.
