Both are free and open source. DubStemMix is a dub console: one tune’s stems on six faders of the Akai MIDImix, stem separation built in, a tape echo and a spring on sends. Mixxx is the community DJ app, for mixing tracks.
Facts about Mixxx come from mixxx.org (Mixxx 2.5.6; stems in the 2.6 beta), checked in October 2026.
Why DubStemMix for a dub version
- Stems from any song: separation built in: drums, bass, instruments and vocals, no other tool needed. Stems and splitting.
- Six faders for the parts: with three dub sends each: The board.
- The dub moves: throw, drop, hold, crash, pull-up.
- Ready on the MIDImix: factory mapping, press SEND ALL, play.
