Stemline

The song is never really finished.

Keep every version of it. Stemline splits any bounce into vocals, drums, bass and other right on your laptop, then lets you hear exactly what changed between two takes. Not a waveform that looks different. The actual reverb you added, on its own.

From a rough bounce to a history you can send.

  • Hear what changedJust the new part — the reverb you added, on its own.
    01

    Hear what changed

    Play v3 against v5 and Stemline cancels out everything they share, so all you hear is what you actually added. The new take. The brighter top end. The reverb tail.

  • Every version, keptOnly uploads what actually changed.
    02

    Every version, kept

    Drop a new bounce and it stacks on top of the last one. Nothing gets overwritten, and Stemline only uploads the stems that actually changed, so a new vocal take doesn't re-upload the whole song.

  • Split without uploadingSplits on your laptop — nothing gets uploaded to separate.
    03

    Split without uploading

    Vocals, drums, bass, other. The split runs on your machine, so an unreleased track never touches a server just to get taken apart.

  • Try a direction, share it safelyNobody can play your files but you and whoever you send them to.

    Try a direction, share it safely

    Start an alt when you want to chase an idea without touching the main version. When you send a link, only the people you send it to can play it. We can't.
