What is it?
KNOCK by producer DECAP collapses the classic drum processing chain into one plugin: Punch (transient shaping), Saturate (three harmonic modes), Sub (tunable sub-bass reinforcement), Air (high-frequency sweetening) and Clip (hard/soft clipping). Five stages, one interface, total recall.
How can it help you?
Stop building five-plugin drum chains. Punch makes kicks cut and snares snap; Saturate adds density with loudness compensation; Sub reinforces weak kick low-end tuned to your track’s key; Air keeps highs smooth; Clip glues and adds loudness. Factory presets from DECAP get you started fast.
