Thanks for the info John. I've set up SD2 and EZ2 for the last few years that way, just wasn't sure about the bus thing. I will check that out.
Do you have any issues where if you first load a SD3 preset with lots of effects on the preset, switch to the 'stereo' mixer right away and all those busses aren't working anymore in the SD3 mixer, even if everything is set to output 1/2? Not touching anything, but load a preset and then switch the mixer to 'stereo' and every buss doesn't work all of the sudden?
Thanks!
