A groove-aware ducking effect. It listens for the kick and the clap, makes a little room for them in whatever it is inserted on, and gives that room back in time with the beat: the recovery follows a note division and a feel rather than a fixed release in milliseconds.
The idea
Classic sidechain ducking works best when it is subtle. Pushing past two or three decibels per hit starts to sound like pumping, and around six decibels the effect becomes obvious. Pocket is built around that: you set a reduction budget and it never exceeds it, even when several hits land at once.
Pocket is not a generic unmasker that compares spectra. It assumes the drums matter, detects when they hit, and schedules the recovery musically. Below a crossover point the low end is ducked as one mono band, so a bass stays full and centred between kicks. Higher up, with Glue raised, the reduction is shaped into a few narrow cuts instead of a broadband dip, so a pad keeps its density.
