When I have session drummer open and am selecting sounds to put in all the kit pieces, I will go through the Media Browser in Sonar until I find a sound I like (such as "Tight Kit Dry Snare 01.flac"), and then I'll drag that sound from the Media Browser right onto the drum itself in Session Drummer. Pretty slick. What I don't understand is that when I right click on the drum I see a drop down with (in the case of the snare) four sounds associated with four midi notes. 37, 38, 39 and 40 (side stick, snare, hand clap, electric snare). This is good, I can put a side stick on 37 as it indicates, and a full snare on 38, etc. But when I drag the sound to the drum, that single sound replaces all four midi notes. How do I get so that I can audition sounds in the Media Browser, and then apply one of those sounds to only a single midi note, so that I am building the snare with different sounds selected for side stick, snare, etc.?
