What's new

Start a full multitrack project from a prompt.

Name the genre, BPM, key, mood, instruments, and direction.

Arrangements come with drums, bass, harmony, melody, and effects in place.

Keep iterating on the same project in words. No need to start over.

Tansen is the music model inside Melodex.

It works on the project itself, not on flat audio.

Edits stay aware of the harmony, rhythm, section, and instruments around them.

This is what every later model feature will build on.

Finish an unfinished phrase in the piano roll from what is around it.

Suggestions follow the nearby notes, harmony, and rhythm.

Turn a half idea into something playable without entering every note by hand.

Ask for a melody from a prompt, or from the key, harmony, rhythm, mood, and section you already have.

It lands in the piano roll and stays editable.

Melodies live in the arrangement, not as loose audio clips.

Stretch a melody out from where it ends.

It keeps the feel, shape, and context of the original phrase.

Grow a short motif into a longer line: generate, listen, continue, edit.

Change music in words without replacing the whole project.

Point edits at a section: chorus, drop, verse, or one part.

Say things like:

• Make the chorus punchier.
• Make the melody more emotional.
• Add strings to the chorus.
• Make the drums less busy.
• Raise the energy of the drop.

The model follows key, chords, scale, tempo, meter, section, instruments, energy, and rhythm.

Chord, melody, motif, groove, and orchestration systems got a full pass.

Guitar and tabla now behave like themselves, not generic MIDI.

Multitrack projects with separate instrument tracks and MIDI clips.

Timeline with sections, snapping, zoom, and loop.

Piano roll and drum editing.

Volume, pan, mute, and solo per track.

The project file is what the model reads and writes, so nothing gets lost between you and it.

MIDI timing stays tight across tracks.

SoundFont playback for electronic and Indian classical instruments.

Handles tempo changes and long sessions better, with less memory on big projects.

Effects per track plus a master bus.

Model-assisted mix passes when you want a second opinion.

Lo-fi mode: vinyl crackle, tape warmth, pitch drift.

Nothing is destructive. You can always back out.

Drop WAV and MP3 into a project.

Audio lines up to your project tempo.

BPM and key detection, audio-to-MIDI, and stem split for drums, bass, vocals, and other.

Recorded parts and generated parts can share one session.

Mix down to WAV or MP3.

Stems per track.

Offline render when you want it faster than realtime.

Stems open in any major DAW.

Native `.musicproj` format.

Save, load, undo, redo, and version history.

Timeline settings stick around. Missing assets can be recovered.

OAuth 2.0 with PKCE, plus magic-link fallback.

Stay logged in across devices.

The model checks its actions before touching your project.

Tougher project-file handling and cleaner errors around playback and render.

Electron app for macOS and Windows.

Better multi-monitor and audio-device handling.

Fixed the annoying keyboard clashes. Timeline navigation is quicker.

Faster, more accurate note completion.

Quicker project load and timeline response.

Less memory on large sessions. Generation and render feel tighter.
