LoZ Ocarina of Time-like BGM Generator — RPG Maker MZ

LARKSONG writes actual tunes — recurring melodies, call-and-response, and ocarina-style ornaments — for a whole overworld, from scratch in your browser.

Where most generators produce ambient wallpaper, LARKSONG is melody-forward: memorable motifs that come back, phrases that answer each other, and grace notes, trills and turns on top. Point it at an area, shape three dials, and it composes and synthesizes a singable loop with no samples. It’s a dev tool — make a track, export it, drop it into your game.

What makes it different

• Real melodies. A motif is written per section and recurs across the form (AABA, ABAC…), so the A-tune is genuinely recognizable — with antecedent/consequent “question and answer” phrasing.
• Twelve areas, twelve genres. Variety you can hear, not just re-shades of one mood:
  • Woodland — playful pentatonic marimba & ocarina
  • Field — heroic march, horns + timpani
  • Hamlet — pastoral folk plucks
  • Ranch — gentle 3/4 waltz
  • Grotto — aquatic harp & celesta
  • Bazaar — bustling ragtime oom-pah
  • Dunes — flamenco: nylon guitar, Phrygian, castanets
  • Sanctum — sacred choral hymn (organ + choir)
  • Fount — twinkling fairy celesta
  • Tempest — whirling fast waltz
  • Cinders — tribal hand-drums
  • Dread — ominous pipe organ
• A from-scratch melodic orchestra: ocarina, flute, horn, nylon guitar, harp, celesta, glockenspiel, marimba, harpsichord, accordion, pipe organ, wordless choir, strings, pizzicato — plus timpani, castanets, tambourine, triangle and woodblock.

You’re in control

• Brightness — from dusky minor modes to radiant lydian/major.
• Liveliness — from still and calm to spirited and bouncy.
• Ornament — from plain to virtuosic (grace notes, trills, turns, pentatonic runs).
• Plus Key, Tempo (Auto / Gentle / Lively), and Length.
• New tune rolls a fresh seed — new mode, tempo, meter, key, lead instrument, form and melody every time. The seed + sliders reproduce any tune exactly.

Export & drop in

• .ogg — game-ready, with LOOPSTART / LOOPLENGTH loop tags baked in. Drop it into audio/bgm/ and RPG Maker (MZ and MV) loops it seamlessly.
• .wav — uncompressed, for editing in a DAW.

Good to know

Runs offline in any modern browser — nothing installs, nothing uploads. A short README with full instructions is included.

LARKSONG emulates the style and techniques of 64-bit adventure scores; it does not contain or reproduce any existing music, and is not affiliated with or endorsed by Nintendo or any other rights holder.

FAQ

Is the music royalty-free? Can I use it commercially? Yes. Everything LARKSONG exports is original and yours to use in commercial or free projects, no attribution required. A credit (“Music forged with LARKSONG”) is appreciated but optional.

Does it use samples or copyrighted audio? No. Every sound is synthesized from scratch with the Web Audio API. It never reproduces any existing melody — it emulates a style.

Will the loops loop seamlessly in RPG Maker? Yes — export the .ogg. It carries LOOPSTART/LOOPLENGTH tags MZ and MV read to loop with no gap. (The .wav has no loop tags; use it only for DAW editing.)

MZ only, or MV too? Both. They both read .ogg for BGM. Put the file in audio/bgm/.

Do I need to install anything or be online? No. It’s one .html file — download it, open it in a browser, work offline.

How do I get the exact same tune back later? Note the seed on screen and keep your slider values; re-enter them for an identical render.

No sound when I open it? Click Play once. Browsers block audio until you interact with the page.

The OGG button says the encoder didn’t load. Refresh and retry. Fallback: export the .wav and run ffmpeg -i track.wav -c:a libvorbis track.ogg (no loop tags that way; prefer the built-in OGG export).

Is this “AI music”? The composition and sound come from hand-written procedural DSP code — not a generative-audio AI model. The tool’s code was developed with LLM assistance, which is disclosed above.
