Your next instrument is a sentence.

You're in Ableton Live, halfway through a song, and you hear a sound no plugin has. Ask Claude for it in one sentence, and it plays right inside your song.

An instrument
An effect
A few effects in a row
Your song stays open
Nothing new to install

Get started How it plays

Musicians call that app a DAW. Par's plugin is an Audio Unit, the kind of add-on Mac music apps load. Playing uses no AI, so it costs nothing to play.

A crayon drawing: a musician at her desk, a small synth keyboard on her lap, looks at her laptop. The yellow star of her AI glows on the screen, and Par's pink brain reaches in with one arm and sets a little tape effect with four knobs onto the top track of her music app. — The ask. Each word lights the part of the plugin it uses. Make my synths sound like the tapes I have on repeat. A little wobble, a little hiss, warm when I push it.

The ask. Each word lights the part of the plugin it uses. Make my synths sound like the tapes I have on repeat. A little wobble, a little hiss, warm when I push it.

How do you make an instrument or effect for your DAW by asking your AI?

Connect Par to Claude and describe the sound the way you would tell a bandmate.
Claude makes it as an app in Par.
In your DAW, put Par's plugin on a track, open the app in its window, and play.

Par Instrument, for sounds you play from the keys
Par FX, for effects on a track
On Mac, as an Audio Unit
No new install for a new sound

From the ask to the track

How one effect goes from a sentence to a track in your DAW, in three steps.

01 Ask like a musician.

No code and no tech talk.

To your AI, connected to Par

Make my synths sound like the tapes I have on repeat. A little wobble, a little hiss, warm when I push it.

Par already knows: On repeat: synthwave, from your Music
02 It lands in your Par.

Your AI makes it as an app in Par: an effect with the knobs you asked for, named the way you said them. Wobble, Hiss, Warmth, Tone.
03 Open it on a track.

Put Par FX on the track and open the app. Every knob shows up in your DAW by name, so you can record Wobble's moves (automation) like any other knob's. Ask for a change tomorrow: the same plugin plays the new version, and knobs that keep their names keep their recorded moves.

Made for one musician.

Example: Inês, a musician, travels a lot. She's making a record about it.
Inês, to her AI

Make my guitars sweep like light across a plane window.

She asks her AI for the sound she hears in her head.
Her AI made it in Par. It opens right inside Ableton.

See how it works

The Window Seat plugin: a flat blue panel with the title Window Seat and the word Flanger, three knobs, Rate, Depth and Feedback, and an airplane window with a coral sun and a white jet trail.

Her effect: Window Seat

A slow, sweeping whoosh over the sound: her guitars move like light across a plane window.

plays today As Par FX, in the Par plugin.

Works on Mac, as an Audio Unit, in Ableton Live, Logic Pro and GarageBand.

How it works

She asked in one sentence.
Her AI built it from parts the plugin already knows: a short echo that slowly moves.
It opens in the Par plugin, on her guitar track. The plugin is installed once.

What she told Par

Her record: psychedelic pop, in A minor, at 96 beats a minute.
Its five songs, by name.
The sounds she recorded on her phone at every stop.

Par does not read the song files in her music app: it knows what she told it.

She asked for two more

The Far Shore plugin: a deep blue panel with the title Far Shore, the words Tape Delay, a shoreline to drag for Time and a knob for Repeats. — **Far Shore** A tape delay: her voice echoes back, a little worn. *plays today*

The Conch plugin: a teal panel with the title Conch and a shell that turns to the notes A to G, with a slider for Ring. — **Conch** A resonator: any sound rings on the notes of her song's key. *plays today*

Can she change it?: Yes, by asking again: "slower, and a little deeper."

You make the music. Par makes what you need to make it.

Inês made hers for her record. You make yours for yours.

A crayon drawing: Inês plays her travel guitar in her plane seat. Her laptop shows the effect Par made for her, a blue window with a red sun and three knobs, and the sound sweeps out of the guitar like light across the window.

Luna di Miele, a synth made in Par: a wall of Italian machines in brass, copper and wood, among them a coffee machine for the filter, a scooter engine for the vibrato and glass discs for the ensemble. — Luna di Miele (Italian for "honeymoon"), a real app made in Par on request. Screenshot from the browser.

Made for one honeymoon.

Luna di Miele is a real instrument made in Par, on request, for a honeymoon in Italy: seventeen Italian machines, each one moving with the sound it makes.

It plays in the browser and inside Par's plugin, in your DAW. Its reverb, vibrato and FM machines come to the plugin in its next version.

Play a pocket version of it, and one made for Tokyo Made with your browser's built-in sound, without the app's recorded sounds.

Chiedi al Par (Ask Par), the AI panel of Luna di Miele: beside a marble Mouth of Truth, someone typed more Capri sun, and the display now reads Capri. — **Chiedi al Par ("Ask Par").** Describe a sound in your own words and Par shapes it. Coming soon, with Par's own AI.

Play two of them here.

Tokyo Rain and Luna di Miele, two pocket synths made in Par on request: one for a trip to Tokyo, one for a honeymoon in Italy. Tap the keys, or play A to K on your keyboard.

Made with your browser's built-in sound, without the app's recorded sounds. Sound starts when you play. Open full screen

Your phone plays it too.

Open the instrument in your DAW on the computer, and your phone becomes its controller: the keys and every knob.

Press a key on the phone and the computer plays it with almost no delay: the two talk directly over your home network. The phone stays silent; the computer is the instrument.

A crayon drawing: someone at a desk plays the synth from a phone held sideways. The laptop shows the whole synth open as a plugin; the phone shows only its controller. The key pressed on the phone lights up on the synth's keyboard on the laptop at the same moment, and a dotted line joins the two keys.

The phone controller of Luna di Miele, in its own style: brass Bend and Mod wheels, a glowing waveform, a split-flap display reading Roma, a marble keyboard with one key lit, and the status Connected to your Mac.

This phone controller is built into Luna di Miele and one other synth made in Par. It works with Luna di Miele in Ableton Live and Logic Pro.

It's like making your own plugin.

For people who know plugins: Par's plugin is an Audio Unit (AU) you install once, and every instrument or effect your AI makes plays inside it. No code, no compiling.

From Claude, connected to Par

Ask Claude through Par. What it makes stays in your Par, next to what Par knows about you: what you have on repeat, the recordings from your trip, what you told it last time. The same instrument opens in your browser, on your phone and inside your DAW.

Software is abundant now. Welcome to the new Renaissance.

For decades, software was scarce, and everyone picked from a shelf. Now it's abundant and practically free: make one in a sentence, or take an idea you love and make it yours.

Hear an effect you love? Describe it to your AI, add “more psychedelic, more like me,” and you get your own version, on your own track. Share it with your friends, and they can play it too.

Coming soon: publish yours for anyone to use, with revenue sharing, and a curated store of professional instruments and effects.

A wide crayon drawing, like a fresco: a musician sings and holds up a sketch of a sound; Par's pink brain listens and takes it, surrounded by cards of her life; a dotted blue line runs from the brain through her apps, a tape effect, a keyboard, a phone, a laptop, a chat and a cloud; and out of them flowers, vines and instruments bloom in a great arch over the whole scene, where three friends play a guitar, a keyboard and a drum.

Why make your sound with Par.

Par makes the instrument you describe, for your record, and changes it when you ask.

	Par	A plugin you buy	Your DAW's own instruments	An AI music generator
Made by asking	Ask in a sentence, and Par makes it.	You choose from what exists.	You use what came with it.	It makes a song, not an instrument you play.
To change it	Ask again. The same plugin plays the new version.	Wait for its maker's next update.	Only the settings it has.	It makes a new version of the song.
What it knows	Your record: what you told Par about it.	Nothing about your record.	The project you have open.	Only what you type in.
In your DAW	On a track, as an Audio Unit on Mac. It plays as you play.	Yes, once you install it.	Yes, already there.	Mostly no. You download the finished audio.
Knobs	Every knob shows up in your DAW by name. Ask for a change and the same knob keeps its recorded moves.	Yes, as its maker designed them.	Yes.	No knobs. It's a finished song.
Where it lives	In your Par. Your other apps and your AI can read it and change it.	In the maker's plugin. Your settings stay in the project.	Inside your DAW's projects.	In the generator's account.

Where the others win: a plugin you buy has years of tuned sound behind it, your DAW's own instruments are already there and tested in your setup, and an AI music generator makes a whole finished song in seconds.

Questions

What format is it?

Audio Unit, the plugin type Mac music apps use, so Mac only. No VST3 version (the other common type) and no Windows version today.

Which DAWs?

Ableton Live, Logic Pro and GarageBand, on Mac.

Do I reinstall the plugin for each new instrument?

No. You install the plugin once. Each new instrument or effect is an app in your Par, and the plugin plays what it describes. A new kind of sound part, such as reverb, comes with a new version of the plugin.

Which AI can I ask?

Claude, connected to Par. Get started shows how.

Connect Par to Claude, and ask for the sound you hear in your head.
