Prompt · MIDI DNA · Templates

Structured prompts & coherent multi-track MIDI

Turn a genre or idea into a ready Suno-style prompt plus aligned Chords, Bass, Melody and Drums — built for producers who finish in a DAW.

A phrase becomes a melody
Syllables become the rhythm, letters become the notes. The same words always give the same melody — try your track title.

No musical theory required for prompts — full control when you open the MIDI studio.

Free web app · tracks you generate with AI stay distinct from each other.

Hear the difference

Same genre, same model, two prompts. On the left, what most people type. On the right, what this tool writes.

Both sides were generated in Suno on default settings. Nothing was edited afterwards.

How it works

Four workspaces in one file. Start anywhere — a genre, your own melody, or a whole DJ set.

Pick a genre and get a Suno prompt. Open Musical DNA when you want the arrangement behind it.

01

Choose a mode

One genre, a weighted hybrid of two, or a bridge that connects genres too far apart to blend — like ambient and peak-time techno.

02

Read the prompt

Style of Music and a bracketed structure map, ready to paste. BPM, key, instruments and era references come from the genre profile.

03

Open the DNA

One click builds up to eleven roles on a shared progression — drums, bass, pads, chords, arp, melody — with intro, build, drop, breakdown and outro.

04

Export

Play the whole thing in the browser, regenerate any role you don't like, then take multi-track MIDI into your DAW and a mix WAV into Suno as reference.

Your melody goes in, variations come out. Or type a phrase and let the words become the theme.

01

Bring a melody

Drop a MIDI file, send one over from Gen, or type a phrase — syllables become rhythm, letters become notes, and the same words always give the same melody.

02

See what it is

Key detection, tempo, bar count, range and a piano roll you can play. Nothing is guessed silently.

03

Mutate

Eight strategies — transposition, inversion, retrograde, ornamentation, sparsification, doubling, augmentation, rhythm shift. Lock the key, the rhythm or the contour.

04

Add accompaniment

Chords and bass built in any genre you choose, in the variation's own key — harmony inferred from the actual notes, not from a preset bank.

A DJ set is a sequence, not a pile of tracks. This plans the sequence before you make anything.

01

Pick an arc

Classic build, peak in the middle, double peak, warm-up, closing set or waves — the shape decides where the energy goes.

02

Set the harmony

Choose a starting Camelot key. Every step moves by a legal DJ transition — a semitone up the wheel, a mode switch, or one dramatic jump.

03

Read the plan

Energy bars, BPM per track, genre roles, and bridge tracks inserted where two genres sit too far apart. Copy the tracklist as text.

04

Build the tracks

Each track has its own prompt at the planned key and tempo. Open its DNA, or download MIDI for the whole set in one go.

Everything you keep stays on your machine. Nothing is uploaded anywhere.

01

Save as you go

Prompts, planned sets and motifs go into the browser's own storage with one click.

02

Come back later

Reopen a set in the planner, load a motif back into the Lab, or copy a prompt straight to the clipboard.

03

Export a backup

The whole library becomes one JSON file — keep it next to your project folder or move it to another machine.

04

Stay offline

No account, no server, no telemetry. The file works with the network switched off.

Built for producers

Not a toy sequencer — a workflow bridge between AI prompts and real arrangement work.

Suno-ready prompts

Style and Structure blocks tuned per genre — pure, hybrid or bridge — ready to paste.

Coherent MIDI

Sections, chord-aware melody, call-and-response bass and FPC drum maps in one pass.

Mix set planner

Camelot Wheel harmony, energy arcs and BPM curves — every track in the set gets its own prompt.

Motif Lab

Drop a MIDI or type a phrase, get variations through eight mutation strategies, add accompaniment.

Play before you export

Fourteen synth voices, piano roll per role, play the whole arrangement in the browser.

Local library

Prompts, sets and motifs saved in the browser. Export the whole library as one JSON file.

Musical DNA, not random loops

Chord progressions come from functional harmony rules, melodies from contour and rhythm generation — not from a bank of presets. Every generation is new, and every genre keeps its own character.

  • Intro, build, drop, breakdown, outro with real density curves
  • FPC and GM drum mapping for FL Studio
  • Regenerate any role, keep ★ takes, export multi-track

FAQ

Is this an AI music generator?

No. Track Generator does not create the final audio track. It builds Style and Structure prompts plus MIDI/WAV references so Suno, Mureka and similar AI tools produce music that is less generic than a default prompt — then you finish in a DAW if you want.

Do I need music theory?

Not for prompts. For MIDI you can stay on auto key/BPM or lock everything manually.

Where does the app run?

Entirely in your browser — one HTML file, no server, works offline. Export MIDI and WAV, finish in FL Studio or any DAW.

Can I use my own melody?

Yes — drop a MIDI into Motif Lab for variations, or send a generated melody there. Chords and bass can be derived from its actual notes.

Will my AI tracks all sound the same?

No. This free web app builds each run from genre DNA, harmony and fresh variations — so generated tracks stay distinct instead of cloning one template.
