I take an empty project and create a Drummer track to which I assign a Designer Drum Kit SoCal+. I observe that when I expand the kit in the mixer (with the small triangle) then it correctly displays all the kit component mixer channels, about 17 of them. So far so good.
What I want to do next to simplify my human drummer’s life as a less sophisticated Logic user is to create a new software instrument track and also assign it SoCal+ instrument as a separate instance. That also works with the following quirk: when I look at the expanded kit component tracks in the mixer, there is only one set, not two. If I collapse the Drummer track, the kit component tracks are still showing, and they do react to either the Drummer track (Kyle) or the human drummer software instrument track.
This is certainly peculiar behavior, but is it normal for Logic? It’s a bit limiting because I cannot have two separate mixwas for each respective drummers upon playback.
