NATIVE APP PREVIEW

A look at the native app.

These native features are separate from StemDeck Online. The current online studio and its learning workspace are described above.

01

Work across decks

Inspect waveforms and shape transitions with deck transport, cues, loops and mixer controls.

02

Shape loaded stem lanes

Adjust drums, bass, music and vocals separately when stems are available. Separation quality depends on the engine and source.

03

Capture the performance

Use recording and arrangement-capture tools to revisit a performed mix. Long-session reliability remains an early-access qualification item.

YOUR BROWSER EDITION

Start here.
Know what’s here.

Use Library, Perform, Arrange and Mixer views in StemDeck Online. Mix decks, arrange audio and MIDI, add built-in effects, capture input and save a portable project.

Current limitations

Arrangement playback is marked as a preview in the current Sattari studio. Browser effects are distinct from native plugin hosting. Track-stem export is not AI stem separation. Save a portable .sattari backup to keep your source audio with your session.

  1. 01Open the current Sattari studio and import audio.
  2. 02Explore Perform, then Arrange and the built-in effects.
  3. 03Save a portable .sattari project and export your mix.
