Hear it together.

Leave notes on the exact second of a track, and everyone on the project sees them.

Start free

Free plan, no card needed

Most feedback on music still arrives as voice notes in a group chat. Half of it is someone asking which bit you mean.

01Notes on the waveform

Put the note where the problem is

Click the waveform and your comment is pinned to that moment, down to the millisecond. Nobody has to work out what “around two minutes in” means.

02Live sessions

Listen together from anywhere

You can see who's in the project, and new notes appear while they're being written. Reply while the idea is still fresh instead of waiting for a call back.

03Full-quality files

The real session files

Full WAVs with no compression, ready to play a few seconds after they finish uploading.

04Revisions

Every version keeps its notes

Each bounce gets its own revision, so the latest one is always obvious. Comments stay on the version they were written about.

iPhone and iPad

On your phone too

Hold your finger on the waveform and slide to the exact spot before you comment. Handy at rehearsal, or on the way home from one.

Who uses it?

  • 01

    Producers and beat makers

    Send a rough mix and get comments on the actual bars. Every version and every note stays in one project, not spread across five chats.

  • 02

    Artists and bands

    Play your part on its own or in the full mix, and flag anything that needs another take. Works on a laptop or a phone.

  • 03

    Musical directors

    Share the arrangement once and the band's notes come back on the bars they're about, so rehearsal starts with the fixes already sorted.

  • 04

    Composers

    Film, TV, games or the stage: send the cues, get notes on the exact bar, and keep every version of the score with its comments.

  • 05

    Engineers and post-production

    Mixing, mastering, broadcast or post: you get notes with a timestamp instead of an email you have to decode.

Common questions

Got a track that needs another pair of ears?

Start a project, upload a stem and send the link to whoever you'd normally ask.

The free plan gives you 5 stems per revision and 2 GB of storage. When your sessions get bigger, Pro and Elite raise those limits and keep your version history.
