Its been possible to split midi drum tracks into individual tracks for quite a while.
Drum software like BFD2 doesn't even require you to do that, though... you have all the tools to tweak each drum any way you want... from the brand of snare drum, to the mic on the bass drum, how much tension on the heads, etc.


Once plugins already exist to take BIAB output and change it, there's very little incentive for PGMusic to recreate the same functionality.
