BPM-001 OWNER'S MANUAL
Building the tools that should already exist. Mostly in a browser. Mostly on purpose.
One flagship product, and the ecosystem that built it.
Sheet Music · Notation · Browser-Native
Browser-native score writing and sheet music rendering. Professional notation in any tab — no plugins, no Sibelius, no installation. The product everything else here was building toward.
Claude · ElevenLabs · Kie.ai — all in the browser, no install required.
ElevenLabs V3 · Kie.ai
Multi-speaker voiced dialogue with emotional direction. Assign voices, write lines, drop in emotion tags — [excitedly], [whispering], [sighing] — and generate expressive audio from the ElevenLabs Text-to-Dialogue V3 model. 80+ voice characters. 70+ languages. Built for game audio prototyping, podcast intros, and scenes that need a soul.
AI Music Generation · Kie.ai
Full AI music generation from text prompts. Generate complete tracks, extend sections, replace parts, remove vocals, upload and remix your own audio. Style descriptors, custom lyrics, negative prompts, and full production workflow — not just a simple generator.
Claude Sonnet · Anthropic
Describe a mood, a reference, a feeling — get production-ready prompts for AI music generators, voice tools, and sound designers. Claude reasons like a composer and speaks the language of the models. Powered by the same frameworks behind Songwright, now directly in the browser.
A polyphonic synthesizer built for audio designers. Web Audio API + Tone.js + Web MIDI. No installation. No server.
All tools run in the browser. No installation. No account. No waiting.

Sep 2025
A back catalog of released instrumentals, always feeling incomplete. Fed them to an AI remix engine as professional-quality source material. The principle: garbage in, garbage out. The results: genuinely startling. Every track presented raw, no DAW.
2025 — Ongoing
Extending sweetened tuning beyond standard guitar. Browser tools that calculate optimal cent offsets for DADGAD, Open G, Nashville — any system. Because equal temperament is a compromise and you're not a compromiser.
2024–2025
The research behind Songwright. Systematic experimentation with source-first production methods, translating the vocabulary of professional composition into descriptors these models can act on. The patterns that emerged became a product.
I've spent 17 years designing music systems for games at PlayStation Studios — scores for The Last of Us Part II, Ghost of Tsushima, Marvel's Spider-Man 2, Journey. Grammy-nominated, BAFTA-recognized work that taught me one thing above all else: the best music happens when you build the right system and then get out of its way.
Back Pocket Music is where that philosophy lives outside the studio. I build tools at the intersection of music theory, acoustics, and AI — not to replace the composer, but to remove the friction between the idea and the sound.
Browser instruments that make complex musical concepts playable. Prompt engines that translate feeling into production-ready direction. Score notation that lives where you already work. Everything here is built with the same conviction: if a tool should exist and doesn't, build it.
The best creative technology is the kind that disappears — leaving nothing between you and the music except the decision to press play.

Caution
Back Pocket Music L.L.C. is not responsible for: decisions made while listening to generative ambient at 2AM, the realization that all music is just air vibrating, or the sudden urge to buy a modular synth you cannot afford. No refunds. No returns. No equal temperament.
