One major complaint about free sample packs is that the levels are all over the place. Kompany’s official packs are mastered at consistent -6dB to -3dB levels. The phase alignment is tight, meaning you can drag a bass loop into your DAW, pitch it to your key, and it will usually sit in the mix without heavy EQ.
Do not just use the kick as is. Take his Kick_Heavy_01 and layer it with a click from a trap pack. Group them. Apply (Multi-band compression) at 30% mix. This retains the punch while adding the "fizz" on top. kompany sample pack
