co-song

The AI that works inside your DAW.

A VST3 and Audio Unit plugin for Ableton Live, Logic Pro, FL Studio — anything that loads a plugin. It writes parts in your key, designs sounds from a description, sings in your voice, and turns a finished record back into MIDI.

Download the free DAW

The first 24 hours are free. Install the plugin, link it to a song.money account, and the day starts then — not when you downloaded it. No card to start.

Parts, in your key

Melodies, basslines and drums written against the key and tempo of the session you are already in. Not a loop library — MIDI you can open and change.

A patch from a sentence

Describe a sound and get a synth patch. “Warm analogue pad, slow attack, a bit of drift”, and it arrives on the track ready to play.

Your own voice

Record yourself once and sing anything in your own voice — or convert a take you already have. Acapella or full instrumental.

A whole mix, back as MIDI

Play a record into it and get the parts out as notes. Separate the stems first and transcribe them one at a time.

Mixing advice that measured something

It listens to the section you are on and tells you what is wrong with it in words. Your audio never leaves the machine — it sends about a dozen numbers.

Your catalogue, from the DAW

What you have released, what it is earning, and what key that track from March was in — without leaving the session to go and look.

Questions

Which DAWs does it run in?

Anything that loads a VST3 or an Audio Unit: Ableton Live, Logic Pro, FL Studio, Bitwig, Reaper, Cubase, Studio One, and the free song.money DAW. It installs into your own plugin folder — no password, no system changes.

Do I need a song.money subscription?

No. co-song is sold on its own. You do need a free song.money account, which is what the plugin links to and what carries your subscription across machines.

What happens to my audio?

Mixing advice never sends it — the plugin measures about a dozen numbers on your machine and sends those. Turning a recording into MIDI does send audio, because there is no way to transcribe a recording without it, and the plugin says so on that screen rather than in a policy.

How does the free day work?

It starts when you link the plugin to an account, in whichever DAW you use — not when you downloaded it, so a trial cannot expire before you have installed the thing. One day per account.
