Stem prep is still a manual job.
We’re building the fix.

StemMaster prints stereo stems, Atmos beds, and objects from one plan, with every analog return aligned automatically. No manual sync, no renaming before delivery.

What we’re exploring

Printing stems means routing, resyncing, and renaming song after song, session after session. Add analog outboard to the mix and it gets worse: every return has to land back in time by hand. StemMaster handles the whole print in one pass, in the box or out.

Set a print plan

Stems, outputs, names, tails, and alternates, defined once.

Route through analog if you need to

Outboard passes queued and returned to their original sample position automatically.

Print Atmos in the same pass

Beds, objects, and fold downs alongside your stems, not as a separate stage.

Auto check before delivery

Names, length, sync, and channel count verified before anything goes out.

Get early access.
