Features
Everything you need to ship a track.
Prompt-driven
Describe the song in plain English. Melodex builds the project, sections and all.
Section-aware edits
Say "make the chorus punchier." Verse and intro stay untouched.
Fully editable
Open any clip in the piano roll. Drag, draw, delete. AI is a starting point, not a cage.
Stem export
Drums, bass, piano, FX. Each track its own WAV. Mix in your own tools if you want.
Local fallback
No API key? No internet? A deterministic interpreter keeps you working.
Native desktop
Electron + Tone.js. Sub-5-second multitrack playback. Same patch, same sound, every time.
How it works
From idea to arrangement in four steps.
Type your prompt
"Chill lo-fi beat at 85 BPM with rhodes piano."
AI builds the project
LLM returns a Zod-validated patch. Tracks, sections, MIDI.
Hear it instantly
Tone.js loads the project. Multitrack playback in under 5 seconds.
Iterate with words
Surgical edits to one section at a time. Or open the piano roll.
The Cursor analogy
If Cursor edits code, Melodex edits sound.
| Cursor (code) | Melodex (music) | |
| Input | Natural language prompt | Natural language prompt |
| Context | Entire codebase | Entire music project |
| AI output | Code diff / patch | Track edit / section patch |
| User works at | Idea level | Idea level |
| Result | Working software | Produced music |
Prompt copilot
Talk to your DAW. It listens.
The chat copilot has full context of your project. Ask for a new section, a tempo change, a mood shift — and watch the timeline update in real time.
Editable everything
Open the piano roll. Make it yours.
Every note Melodex generates is fully editable. Drag, draw, delete. The AI gives you a starting point — you keep total control.
How it works
Create music like you write ideas.
Describe what you hear. Melodex turns it into a fully editable project — drums, bass, chords, melody — instantly.
Your next song is one prompt away.
Free during private beta. macOS, Windows, Linux.
