Hi Scott,
I'm having similar issue using Logic Pro X with latest version of Superior Drummer 2.
Isn't it common in real world recording to have mono mic on kick, snare and stereo on overheads?
I watched a presentation on EZ drummer 2 and noticed on its mixer section that kick and snare were mono while overheads were stereo (as expected).
Does SD2 also have a way to do this?
Thanks for the help in this.
Regards,
Eddy
