Running BIAB Mac 2022(609).
Big Sur 11.7.2

Using the Drum Stem Feature.
Exported 5-10 drum tracks (my term) from biab as .wav files to my daw(Logic).

I noticed some aberrant behavior the other day working with an existing arrangement.
It seemed with certain tracks, the ride for example, I would hear other drum parts.
Not faintly but right up there in the mix.

I did not expect this.

This morning I built a simple blues from scratch, selected a 3 instrument blues style. THen I added a new "stem" drummer, rebuilt the project and exported the .wav files like I've done for years.
Nothing fancy at all.

In my DAW, the track labelled "ride" i can clearly hear the snare, the ride, and the crash.
The track labelled "hiHat, I can clearly hear the snare and the ride.
Clearly, not ghosts.

I've also notice certain parts (snare top, snare bottom ) seem mixed at greatly different levels. That's a minor issue compared to the bleeding.
I do export all my tracks, flat & center

I know its difficult to isolate each drum in a kit 100%. Nevertheless this seems to defeat the purpose of "stems".


Is anyone experiencing anything like this.

THanks in advance
