Can anyone here recommend one that they have actually used? I am thinking of trying Drumtracker as I already have Superior Drummer and Metal Foundry... Any recommendations or tips are appreciated. Thanks!

I own Drumagog and it's amazing but it's not free though. They are also coming out with version 5 soon that looks promising. cam

Why? Use the tools you already have! D

I like DrumReaPlacer

+1 for DrumReaplacer, but it obviously won't work if your samples are in .gog or something similar. Works damn well though.
