The Mix Management feature allows users to save, retrieve, update, and delete custom audio mix states for individual tracks. A “mix state” captures the specific playback settings—namely the volume levels and mute statuses—for the individual stems (files) comprising a track.
This enables several key user experiences:
Listeners can save their progress or preferred mix and return to it later.
Producers/Owners can save different preset mixes for their tracks.
Platform Integrations can manage mix states on behalf of their own end-users transparently.
⚠️ We will discontinue Mix That on 1 September 2026.
Unfortunately interest has not been strong enough for it to be feasible
for us to continue. We apologise for any disruption this may cause.
Stemplayer.js
will continue to be freely available on GitHub and we recommend using that
to host your own player.
