Umm,
Yep,SSD4 to "Construct Kit" and also "mixer page" with each drum piece,then you can just add an Audio Track in Sonar,then change the individual drum pieces in SSD's "out"s to match Sonars Audio track" ins"[sometimes theyr'e different No's. you have to experiment].
What I do is set up a "Project Template" and Save,so it then turns up as an option for a "New Project",with Track "1" in Sonar the standard "Instrument track" for the SSD synth,then add 2 Audio tracks,and route the "in's" of the NEW 2 audio tracks,to the OUT's of the "Kick,and Snare",and then,instead of a track for EVERY piece,track "one" is isolated with the cymbals/overheads/toms/room sound,and I can have totally separate deals for the Kick/Snare.....better than all on track one,less mess than every track,for every piece,anyway that's the way I'm using SSD4 ATM. Hope this makes "some" sense.
