Do you train on my music?

No. We never train our models on your uploads. Automix mixes and masters the music you bring, and you keep every right to it.

Read our AI statement
Do I need mixing experience?

No. Automix creates a starting mix from your stems. Use the live Mix Console to adjust it by ear, and Mix Insight to understand the changes.

Can I master a mix or use a reference track?

Yes. Master a stereo mix on its own, or use a reference track to guide its sound. Mastering and reference matching are included in Pro.

Can I keep working in my DAW?

Yes. Export processed stems and editable DAW projects, including Ableton Live sets, from the classic mixing workflow. Mix Console exports a final mix and processed stems. Automix inside Ableton Live is coming soon.
