I write down my miditrack for Addictive Drums, than I take all the kick hits for example.
create a few new tracks (for kick, 4-5, i think that's enough for fast metal) and than put
the kick midi track in their, than I delete a few hits, so if i have a bar with 4 kick hits, I
delete hit 2,3 and 4, so that on track one, I only have the first hit, than on track 2, I delete
hit 1,3 and 4, and so on, I do this through out the song, changing it from time to time.
Than I use ReaSample on every track with a different sample (same kit and stuff, just
another hit) to get more diversity in there.
It takes some time, but it works for me
and it's free, still have no clue how to load samples
in Drumreaplacer.
I only do this with the kick at the moment, because I dig the other sounds I get out of
Addictive Drums, I just think that only one kick sample sounds a bit strange, 4 or 5 different
sound more natural.
In the end, I send all my drums to the drumbus, put a little bit reverb and compression on them
to glue them together, that's it.
edit: short version, I use different miditracks
