So a real drawback of AD2 is that you're forced to do your sound design for the cymbals within AD2, as you can't export each cymbal as a separate stem and do it in SONAR.
Seems to be trying to force you to do ALL of your work within AD2 and just export the 2-track stereo.
Since I haven't yet attempted to adjust the stereo field of XLN's kits and presets, I hadn't noticed this as a workflow issue.
Strikes me as a real PITA. Best I can do is offer my sympathy.
