Setmaster Press

KRATEO Setmaster is mastering for recorded DJ sets. It levels a set with one gain per drop and a smooth ramp between drops, and nothing compresses it, so each track keeps its own transients and dynamics. The sound only changes where it goes louder into the clipper, or on a click you marked. Setmaster runs in a desktop browser, with nothing to install and no account, and the first 60 minutes of a set are free.

The tracks in a DJ set are mastered already. What differs between them in a recorded set is their level: the DJ mixed for the room they played in, or set a trim or a channel fader by ear, and the drops come in at different loudness. Setmaster is not a track mastering service. Instead of compressing the whole set again, it leaves the tracks as they are and only evens out the level between drops.

For DJs who record long sets, up to four hours, Setmaster does the job you could do by hand in a DAW: it finds each drop, measures it, lifts the quieter ones toward the loudest, and shows you every number it picked. It levels by volume alone: it proposes one gain per drop, you can change any of them before you render, and your upload stays as it is. Machine learning does one job here. It finds the drops; the gains come from measurement and arithmetic.

For the final level, clean puts your music's true peak at -1 dBTP. Louder goes into the clipper, and Setmaster marks the point where it starts to sound rough. You hear every step before you render. A vinyl recording can carry clicks louder than the music. Setmaster's artefact detection finds them, you review each one, and the clicks you mark come out of the mastering, so they don't hold your level down.

The editor is there for when you want to change something: trim, cut, EQ, pan, and any drop it proposed. The master arrives by email. Setmaster is part of KRATEO, an independent DJ ecosystem created by El Kolbo, a DJ and producer based in Germany.
