For Ableton Live · Coming to macOS

Stems that sound exactly like your master.

Leave every plugin on: master, group and track. Hit print and StemShip does the rest: it exports, names, groups, matches and packages your stems so they add back up to your main mix. Set it and forget it.

The problem

Printing stems can eat hours per song.

Everybody's workflow is different, and a lot of sessions have wild routing. Stems get printed, but they rarely sound like the record the client approved.

1

Your master chain changes everything

Layers of limiting, saturation and bus glue shape the Main. Print the stems without them and they don't sound like the record.

2

Turning it down and hoping

Most people pull the master down or drive the stems softer so the processing bites less. Either way it's a compromise.

3

Re-leveling by ear

Drag the stems into a blank session and re-mix them to match the Main. It never gets exactly there.

4

Hours per song

Organize, group, print, check. If anything goes wrong, you do it all again or troubleshoot for an hour or two.

"Part of exporting stems in my life is waiting around hoping I've done it right, then opening a blank session, dragging all the stems in and re-leveling them by ear back to the main mix. It never gets exactly close."
StemShip co-founder, working producer

No AI

Nothing separated. Nothing generated.

StemShip only works with what your own session prints. It doesn't pull sounds apart or invent audio. It adjusts levels until the math adds up, and the null test proves it.

What you get

Everything between "approved" and "sent", automated.

Built with a working producer's real delivery process, not a guess at one.

Stems that match the Main

Tracks, groups and the Instrumental all carry the master and bus processing, so they add back up to the approved mix.

Null-tested every time

Every delivery is checked against the Main. You see the result before the client does.

Tracks, groups or both

Main, Instrumental, group stems and individual tracks, in one print.

Your naming, every time

Save a spec per label or library: artist, title, version, BPM, key and stem names.

The client's format

48 kHz / 24-bit for sync, or whatever the label asks for, converted cleanly.

Packaged to send

Folders, a delivery sheet and one zip, ready for Dropbox, DISCO or Drive.

Built by working producers. Every step of StemShip is modeled on how stems actually get printed for labels, sync libraries and mixers.

FAQ

Questions

Do I need to turn my master or bus plugins off?

No. That's the whole point. Print with everything on, exactly as approved. StemShip matches the stems to your Main so they carry that processing and add back up to it.

Is this AI stem separation?

No. StemShip never separates or generates audio. Your stems come straight from your Ableton session. StemShip only adjusts each stem's level, band by band and moment by moment, so they sum to the Main, and the null test shows you the result.

Does it work with my routing?

That's the goal: groups, sends, returns, sidechains and heavy master chains. Everybody works differently, so the beta is about testing it on as many real sessions as possible.

Which Ableton and Mac do I need?

StemShip is built for Ableton Live on macOS. Apple Silicon Macs are supported at launch, with an Intel build to follow.

How many computers can I use it on?

Each licence works on two Macs, like your studio machine and your laptop. You can move it to a new Mac any time.

Is there a free trial?

Yes. The free demo does everything the full version does on songs up to 30 seconds long, so you can test it on your own sessions before you buy.
