Andrew,

As musocity suggested above I went to the source files at \biab.

Under \drums\americanaSlow8thsFred_75

check out the _Ride.m4a.
or the _hiHat.m4a

Is that much bleed to be expected?
Sounds like pretty much the full kit less the kick.

If those are correct I'll keep at it.
Possibly something was lost in translation between biab and Logic.
Simple user user error could be at work. Pebcak.
Wouldn't be the first time.

Again, I'm very much interested in trying to use the stems in my backing track projects.

Alternatively If the source is not as its should be, I will stand by.

Thanks,
geeze
