@ritsaert - in case you didn’t see them (I didn’t until just now), @Daisuk shared some sweet kits in these threads:
One particularly nice technique I noticed in these is to have some of the samples have a slightly delayed copy or slap back sound in them as well. At different tempos this gives all kinds of shuffly rhythmic goodness.
Inspiring stuff. If I find some time I’d like to make another kit or two this weekend, and I will share here for sure - the kit I shared above is ok, but I can do better.
