Features

Everything you need.
Nothing you don't.

Built by engineers, for engineers. Every feature exists because someone in a real session needed it.

Live

Instant A/B switching

Gapless switching between Demo, Mix, Master and Reference with keyboard shortcuts. Switch mid-bar without losing the groove — loudness is matched, so you compare quality and not volume.

Client

Share & approve

One link for your client. They listen, leave notes and hit approve — no account, no download, nothing to install. You see it land in your dashboard.

MASTER APPROVED
Notes

Feedback on the second

Timestamped notes that pop up while the track plays, a full log per revision, and the approval history that goes with it. No more "somewhere in the second chorus".

Blind

Blind test

Labels and waveforms disappear and the order is shuffled, so you judge on sound alone. The truth comes out when you cannot see which version is which.

VERSION 1

Three steps. Zero friction.
