How they work together

One progression, three parts

The agents listen to your chords and write over them, so a whole idea starts from one prompt.

  1. Chords

    Type a vibe into Chord Agent 2 and hit GENERATE. The progression comes back with chord names, key and tempo, voiced and played in rhythm.

  2. Bassline and melody

    Bassline Agent and Melody Agent listen to your Chord Agent 2 track, or link straight to it with Agent Link in Chord Agent 2.1, and write a bassline and a melody over it from a prompt.

  3. Change the chords

    Refine or regenerate in Chord Agent 2: the bassline and melody re-fit instantly. Drag each part's MIDI into a clip when it's right.

FAQ

Questions

What do I need to run them?

A Mac with macOS 11 (Big Sur) or later, Apple Silicon or Intel, or a 64-bit PC with Windows 10 or 11. Every agent comes as VST3, Audio Unit and a Standalone app on Mac, and as VST3 and a Standalone app on Windows, so it loads in Ableton Live, Logic Pro, Bitwig Studio, Cubase, Studio One, Reaper, FL Studio and other hosts.

How many computers can I use a licence on?

Two at a time per licence. A bundle key covers all three agents on the same 2 computers.

Do Bassline Agent and Melody Agent need Chord Agent 2?

No. Each works on its own: they listen to any chord track and read any .mid you drop on them. With Chord Agent 2.1 they can also link straight to it with Agent Link.

What if it's not for me?

Email support@sonic-weapons.com within 14 days of purchase for a full refund. You can cancel the yearly renewal any time.

I own Chord Agent v1. Do I pay again?

No. Install Chord Agent 2, open LICENSE, choose “I have a v1 serial instead” and enter the email and serial you already have: you get a Chord Agent 2 key back. How the free upgrade works.

I already have Chord Agent 2. Should I buy the bundle?

No: add Bassline + Melody to your existing key for $19/yr. Your key and your Chord Agent 2 stay exactly as they are.
