Stem Studio

Stem Studio pulls a track apart into four separate lanes: Vocals, Harmonic, Bass, and Drums. Mute a lane to hear the track without it, scratch a lane on its own, or bounce a combination out to a new file. The separation happens on your Mac, and nothing is uploaded.

Open it and drop a track

Pick Stem Studio from the view button in the header, or from the View menu. It isn't in the V cycle, so those are the two ways in.

Stem Studio works on deck A only. Drag a track onto it and separation starts on its own, no button to press.

While it runs

The header counts up, Separating stems, and the lanes fill in from the left as the audio comes through. Everything past the point it has reached is dimmed. When it's done, the header reads Stems ready.

You don't have to wait it out:

• Playback starts early. After about five seconds of finished audio you can hit play, and the separation keeps running ahead of the playhead.
• It keeps going in the background. Open Settings or go elsewhere in the app and the job carries on. Come back and it's where you left it.
• Cancel with the button beside the status. That throws away the partial files.

Loading a different track stops the current job.

A whole track takes roughly a fifth of its own length, so a five minute track is done in about a minute. Library analysis pauses while a separation runs, then picks back up.

Playing with the stems

• Mute a lane with the speaker button next to its name. A muted lane fades back so you can see at a glance what's off. There's no solo and no per lane volume: mute is the control.
• Scratch a lane by dragging on it, the same as scratching the deck, but only that stem moves.
• Space plays and pauses.

Bouncing stems to a file

Click Export in the header once the stems are ready. In Export stems, tick the stems you want, pick a format, and choose where it goes.

• Stems to include starts with all four ticked. What you pick is mixed down into one file, not four separate ones.
• Format is FLAC, WAV, or MP3. FLAC is the default and is lossless.
• Keep tags and comments carries the original's metadata across. It's on by default.

Ora DJ names the file after what you picked: all four stems is a Stems Mix, everything except the vocals is an Instrumental, and a single stem takes its own name, so you get something like Track Title (Instrumental).flac.

A limiter is applied on the way out, so the bounced file never clips. If you save it into one of your library folders, it's imported and analyzed like any other track.

Limits

• Tracks longer than ten minutes can't be separated.
• Separation is deck A only, and there's one job at a time.
