DFHS has a slight problem, they didn't edit the samples sharp. The drummer I work with at the moment complained that the timing of the samples wasn't ok, so I took a look inside the wavefiles. Turned out the variation from datastart to actual sound can be as much as 9 Milliseconds, ask any drummer how much that is and he won't like it when that's added to his performance, expecially when it's random. This was on a hihat, but some cymbals also have this problem (toms, kick & snare are -ofcourse- DFA). And it's not a constant delay. Right now I'm busy converting some cymbals to a Kontak2 file, so I know they will start exactly on time. K2 has a nice cyclefunction so there won't be a machineguneffect.
But it's a lot of extra work..
