Spec
Your idea captured clearly: what the scaffold will do, what you’ll build next, and what’s out of scope—so you and your AI helper stay aligned.

Build the audio plugin
you keep imagining
Describe your plugin idea in plain English. Spec → Scaffold gives you a scoped plugin spec, a playable browser prototype built around it (the fast first step), AI prompts to vibe-code it further, and a JUCE learning path for taking it native (VST/AU) when you're ready.

Spec → Scaffold — $49
What it is
Not a finished product. Not a blank tutorial. A personalized starting point that already makes sound.
Scaffold
A browser zip with Web Audio already wired. Double-click, click Start, hear sound. Then open the folder in Cursor and follow the prompt chain.
Prompt chain
Copy-paste prompts in order: understand the code, extend your main feature, polish the UI. Small steps. One feature at a time.
How it works
Three steps from idea to a scaffold you can hear and extend.
Describe your tool
Tell us what you want in plain English—pad machine, click track, sampler toy, whatever you’re imagining. No jargon required.
Get Spec → Scaffold
We turn your idea into a scoped spec and a runnable starter zip (target ~48h after intake). Open src/index.html and listen.
Vibe-code the rest
Use the included prompts with an AI coding tool. Grow the scaffold into your music tool—at your pace.
Who it’s for
If you’ve ever wished a tiny custom music tool existed—and you’re curious about AI coding—this is your on-ramp.
- Producers who think in sound, not syntax You know what you want to hear. You’re ready to steer an AI helper instead of starting from an empty repo.
- Musicians exploring vibe coding You’ve seen demos of AI writing code. You want a music-shaped project that’s already making noise.
- Tinkerers who outgrew presets Stock tools almost get there. You want a small browser music tool built around your workflow—starting from a scaffold, not zero.
Try a free sample first
A 5-minute win: hear Web Audio in Chrome, then change it with one AI prompt — before you buy.
- Download & unzip the free ambient pad starter, open
START-HERE.txt. - Hear it: double-click
src/index.html(Chrome works best) and click ▶ Start. - Change it with AI: open the folder in Cursor, paste the one prompt from START-HERE, refresh, listen.
Spec → Scaffold matches your idea to one of four engines: pad / drone, drum machine, click track, or sampler. Not sure how to describe your idea? Read Writing a good tool idea (Will / Won't / Build-next).
FAQ
Straight answers before you buy.
What is Spec → Scaffold?
You describe a music tool in plain English. Vibepatch returns a personalized spec and a playable browser prototype of your plugin idea as a zip, plus AI prompts, a mini ebook, success checklist, prompt cheat sheet, and resources sheet so you can grow it in Cursor or a similar assistant. $49 — buy on Gumroad.
Do I need to know how to code?
No. The scaffold already makes sound. You open it in an AI coding tool, follow the prompt chain, and extend one feature at a time. Curiosity helps; a CS degree does not.
Is this a finished VST / AU plugin?
No. You get a browser-based Web Audio starter—not a compiled DAW plugin. It’s a working start you can run, hear, and extend.
How fast is delivery?
Target turnaround is about 48 hours after intake answers are received.
What’s included in the zip?
Runnable src/ (HTML/JS/CSS + Web Audio), SCOPE.md and SCOPING.md, a README written for you, ordered prompts, Cursor rules so the AI stays on track, and a guides/ folder with the mini ebook, success checklist, prompt cheat sheet, resources sheet, and idea-writing guide.
