Melodex is your studio for turning ideas into music you can edit.

The best way to produce with an agent

Built to produce a real session

Start with a hook, loop, or reference and get drums, bass, chords, and melody arranged on an editable timeline — not a flattened audio file.

Keeps the song in context

Every pass understands tempo, key, section energy, and the parts already playing, so a new bassline or hook still belongs in the same record.

Adapts to how you produce

Set your defaults for feel, groove, loudness, genre, and arrangement density, then let Melodex apply that taste across future sessions.

Finish inside the idea

Keep shaping the song in Melodex with editable parts, arrangement-aware changes, and clean exports when the track is ready to share or finish.

Prompts turn into sessions

Describe a song and get drums, bass, chords, and melody on a real timeline — not a dead MP3.

Copilot generating a first arrangement

Works on the session, not a file

Copilot writes into tracks you can mute, swap, and rewrite. Every pass stays aware of tempo, key, and the parts around it.

In every DAW, at every step

Bounce a mix, stems, or MIDI and open it in Ableton, Logic, FL Studio, Cubase, or Pro Tools.

Keep iterating in words

Ask for a second verse, a drier kit, or a longer outro without starting over. Copilot changes the session in place.

I mostly use it to get unstuck. If the first idea is boring, I ask for another direction instead of staring at the same loop for an hour.
Tristan RheeBeat maker
It still lands in a session I can edit, which is the important part. I don't want a finished MP3. I want something I can mess with.
Sayan BanerjeeProducer
The useful part is speed. I can try three versions of a cue before lunch and keep the one that actually feels like a scene.
Tiffany FongProducer
I don't keep everything it makes. That's kind of the point. It gives me enough to react to, then I replace what sounds too obvious.
Ryan KennedyBeat maker
For quick sketches it's just faster than opening a template and pretending I know where the track is going.
Alex OlimBeat maker
I like that I can say 'less busy' or 'make the hook lift' and stay in the same idea instead of starting a new file.
Daniel KwonProducer
