Built for working mix engineers

Mix revisions without the mess

Send one link. Your client clicks the waveform to leave notes. You get a checklist with timestamps that are actually right — and work it from inside your DAW.

The current workflow

The current workflow

You're mixing. A client emails notes. You copy them into a list. You work through them. You bounce. You upload. You email the link. You wait. They reply with more notes — against the wrong version. You do it all again.

How Mix Revision works

Three steps.
One tool.

01
Upload the bounce.
Drag it in, or let Relay watch your bounce folder and upload new passes automatically.
02
Send one link.
No client accounts, no downloads, no expired links. They click the waveform to comment — on their phone if they want.
03
Work the notes.
Every note becomes a checklist item with the exact timestamp. Click a note and your playhead jumps to the spot in Pro Tools, Reaper, or Logic Pro.

Inside your session

The notes come
to you.

See notes inside your session.
The plugin puts the task list right in your DAW — Pro Tools, Logic, Cubase, Studio One, and anything else that loads AAX, AU, or VST3. In Pro Tools, Reaper, and Logic Pro, clicking a note jumps the playhead to it. Check it off without touching your browser.
Bounce. It uploads itself.
Relay watches your bounce folder. New pass lands, it uploads, your client gets the link. You never leave the session.

AAX · AU · VST3 — macOS 11+. Windows support coming.

What your client sees

A link. A waveform.
Nothing to install.

A clean player, the waveform, and nothing to install. They click, they type, you get the note — timestamped.

No account, no download, no app to open.
Works on their phone with zero setup.
The timestamp is wherever they clicked — always right.

Why this exists

From the co-founder

We built this because I was sick of switching between five apps every time a client sent notes. I wanted one place where the note lands and the checklist is already waiting for me.

FAQ

Before you start.

Does my client need an account?
No. You send one link — they click the waveform and leave notes with no login, no download, and nothing to install. It works on their phone.
What audio formats can I upload?
WAV, AIFF, MP3, FLAC, and MP4, up to 2 GB per file through Relay or 500 MB in the browser. Every upload is checked by its actual file header, not just its extension, so a mislabeled file gets rejected.
Can I stop clients from downloading the mix?
Yes. Download is off by default. Flip “Allow client download” per song when you want to hand off the file — until you do, the review page never generates a download link for the client.
What DAWs does the plugin support?
Any DAW that loads AAX, AU, or VST3 plugins — Pro Tools, Logic Pro, Cubase, Studio One, Reaper, Ableton Live, and more. Clicking a note moves the playhead in Pro Tools, Reaper, and Logic Pro; elsewhere the task list works and the playhead stays put. macOS 11 or later; Windows support is coming.
What happens after the 14-day trial?
Nothing is charged automatically — there is no card on file. Your account becomes read-only, and read-only means: your songs, notes, and files stay put, you can download everything, and existing client links keep playing. The first time you open Mix Revision after the trial, a 30-day countdown starts. Subscribe at $29/mo before it ends and it’s all exactly where you left it. If you don’t, your projects and audio are deleted, and we email you a week before. After a paid subscription ends, your audio is kept for 12 months.
Is my audio secure?
Your files live in a private bucket and are only ever served through short-lived signed links — never a public URL. Review links use unguessable tokens, every table is locked to its own engineer, and every listen, view, and download is logged so you can spot a leaked link.
