*Engineer included.
**Spider-Man is not.
Tell it how you want to sound. It measures every plugin on the way in and out, catches what you’d miss, and plays you the plan before anything changes, with your own plugins. One undo takes it all back.
FIG. 01 — “MAKE ME A HARMONIZER THAT TURNS ONE VOICE INTO A CHOIR”
TURN THE REVERB’S KNOBS ↘
It hears your mix
before and after every plugin
A plan you hear first
one undo step per change
— it listens in numbers
— the first sessionOvrtone started with an AI mixing a vocal in another DAW by looking at screenshots. Two hours in, it had still missed five things. So we built a DAW it can measure.
Meters read −15, then −45, on the same audio.
Reads every plugin’s input and output as numbers.
An armed track played the live mic into the mix.
Warns you when a track is passing live input.
One loud spike fooled Normalize, and the take came out too quiet.
Reads the singing and the spike separately.
Demo-mode plugins went unnoticed.
Flags demo-mode plugins and swaps in stock ones.
The master clipped at +3.1 dB, with no alert.
A safety limiter on the master, and a clipping alert.
Before and after every plugin: level, loudness, true peak, and how hard each compressor is working. The engineer gain stages by those numbers, and you see the same ones.
It tells you when it finds one, and what it did about it.
Bigger changes come as a plan. Play A, your mix as it is, and B, the engineer’s version, at the same loudness, so louder can’t fool you. Then apply it, or don’t. Every change is one undo step.
Plug in, hit record, sing. A raw take, nothing on it yet.
In the chat: “make my vocal warm, close and a little dark, with a big wet reverb.”
The engineer picks from your own plugins, sets each one and gets the levels right by measuring every plugin, not guessing. You watch it happen in your mixer.
Hear it before it’s applied. A/B the before and after, then apply. One undo takes it all back.
Don’t have the plugin? Ask. “Make me a harmonizer that turns one voice into a choir.” It writes it, builds it and drops it into your chain.
“Make me a harmonizer plugin that turns one voice into a choir.”
Don’t own the plugin? Describe it. The engineer writes it, builds it, checks that it works, puts it in your chain and sets it up. Then you play. That’s the conversation in the window at the top of this page.
Plugin building comes with Pro, Studio and the license.
Ask for chords and it offers three, from safe to unexpected. You pick; it learns what you like, whichever AI is behind it. You still write the song.
Your projects, recordings and plugins stay on your Mac, in your project folder. Nothing is locked in our cloud.
The engineer uses the same controls you do, and you can see everything it did.
Before and after every plugin: level, loudness, true peak, how hard a compressor is working. Never a screenshot.
Use our engineer on a plan, or your own AI with the license: Claude Code, an Anthropic or Moonshot key, any OpenAI-compatible service, or any AI agent that speaks MCP.
Bigger changes come as a plan: you can hear it first and A/B it at matched loudness. Every change is one undo step. Big volume jumps are capped and a safety limiter keeps the master from clipping. It asks before destructive steps, such as removing a track or a plugin.
It works with the AU and VST3 plugins you already own, knows what their controls do, and tells you when one looks like a demo.
— for developersEverything in the window is also a command, so the engineer can do anything you can, and you can see exactly what it did. Every change is one undo step. AI agents can drive a session over MCP.
