i layer all my kicks, all the time...and have never run into this. i always use a deep bassy kick for body and a "skin" of a kick from a record for...well, skin. the skin is low volume, the body is high volume/pitched down. their frequencies never overlap this way, and the result is clean and sounds good. later on, i compress this down. the result is a decently accoustic drum hit that bangs harder than just the original skin would have - and the compression melts everything together nicely. roll off the bottom end, boost it around 160 (before compression, of course) and you're damn near good to go.
if only i was as good at layering snares.
see thats the thing... the "skin" is the part of the kick over like 200hz. what if i like the skin of one of my samples but the bottom end phucks with the others? thats where simult and seperate filters come in. it sounds like alot of other producers use this too. yeah, i could do some workaround like hitting a bunch of pads at once or going in and manually putting stuff in in step edit, but why? most people like the mpc for the quick workflow, why take features away?
