Six capabilities that change everything.

These aren't just features — they're the foundation of a new way to make music.

01

Natural Language Composition

Describe what you want in plain English. "Upbeat lo-fi beat at 85 BPM with jazzy chords and a mellow vibe." Melodex understands context, mood, tempo, and genre.

02

Full Multitrack Generation

Get a complete project instantly. Drums, bass, piano, pads, melody — all tracks generated and arranged. Not just a loop, but a full song structure.

03

Section-Aware Editing

Tell Melodex to "make the chorus punchier" and only the chorus changes. The verse, intro, and outro stay exactly as they were. Surgical edits, no rewrites.

04

Interactive Piano Roll

Every generated note is editable. Open any track in the piano roll — drag notes, draw new ones, delete, quantize. AI is your starting point, not your cage.

05

Stem Export

Export individual tracks as WAV files. Drums, bass, chords, melody — separate stems for mixing in your favorite DAW or for use in videos and games.

06

Chat Copilot

Full conversation with your project. Ask "add a bridge after the second verse" or "change tempo to 120 BPM" and watch the timeline update in real-time.
