REDLINE — Arcade-Racing BGM Generator for RPG Maker MZ & MV

REDLINE forges original arcade-racing music — pounding four-on-the-floor electro, neon synthwave, breakbeat pursuits and metal-electro showdowns — entirely from scratch in your browser.

Point it at a mode, shape three dials, and it composes and synthesizes a loop with no samples and no repetition. It's a dev tool: make a track, export it, and drop it into your game. Your loops are original and yours to ship.

What makes it different

• Eight modes across the electronic spectrum — from hypnotic techno to distorted metal-electro, each with its own beat, bassline and lead.
• Built to drive — kick-locked grooves, rolling synth arps, riser-and-impact fills at every phrase, and lead riffs that escalate with Aggression.
• Pure synthesis — saws, subs and distortion generated live — no samples, no loops off a disc.

8 modes

• Sprint — four-on-the-floor electro
• Drift — neon synthwave
• Pursuit — breakbeat chase
• Nitro — peak-time rush
• Circuit — hypnotic techno
• Underground — dark garage
• Highway — uplifting drive
• Showdown — metal-electro hybrid

You're in control

• Aggression — smooth → brutal (distortion & density)
• Speed — cruise → redline (tempo)
• Neon — noir & dark → blazing & bright (mode & filter)
• Plus Key, Beat (Auto / Four-Floor / Breakbeat — the drum engine), and Length (8 / 16 / 32 bars).
• Reshuffle rolls a fresh seed — new mode, tempo, instrumentation and line every time. The seed + sliders reproduce any track exactly.

The instruments

Every sound is synthesized from scratch — detuned saw-synth leads, distorted electric guitar, driving synth bass, glass/dark/bright pads, 16th-note arps, four-on-floor & breakbeat kits (kick, clap, electronic snare, hats), risers, impacts and crashes. Harmony draws on minor, dorian, phrygian, phrygian-dominant, minor pentatonic, lydian and major, at 110–168 BPM.

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.

REDLINE emulates the style and techniques of racing scores; it does not contain or reproduce any existing music, and is not affiliated with or endorsed by EA or Criterion Games or any other rights holder.

FAQ

Is the music royalty-free? Can I use it commercially? Yes. Everything REDLINE exports is original and yours to use in commercial or free projects, no attribution required. A credit ("Music forged with REDLINE") 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 track — it emulates a style.

Will the loops loop seamlessly in RPG Maker? Yes — export the .ogg. It carries LOOPSTART/LOOPLENGTH tags that 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/.

Can I use these outside RPG Maker — for another engine, a video, or a stream? Yes. The .ogg/.wav are ordinary audio files usable anywhere; the loop tags are simply ignored by tools that don't read them.

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 track back later? Note the seed shown 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.
