Eurorack rig intelligence
PatchHive
A deterministic Eurorack rig-intelligence and patch-book publishing system — without synthesizing audio or controlling hardware.
v0.3.0-alpha.2 · not production · payments test-mode only
What it is
PatchHive turns a verified modular rig into clear, publishable patch libraries.
Every published patch is complete and readable on a single page — a compiler and publishing system, not a synth or hardware controller.
In short
Turn a verified modular rig into clear, publishable patch books — complete on one page, without pretending to be a synth or hardware controller.
Canonical MVP and PatchBook Design Engine land on main; design engine flags default off. Visual System Intelligence P0 covers photo evidence, inventory gate, and multi-photo fusion with mock vision. Production deploy has not been performed; live payments stay disabled.

Changelog
Milestones in plain English, newest first, to Nov 7, 2026
- Exported patch-book pages now draw each patch's diagram, name its modules and list its steps.
- Hundreds more catalog modules confirmed against makers' own pages; duplicate entries retired.
- Redesigned the rig workspace: drag, tap or keyboard to place modules, with Undo and a light theme.
- Added a plain privacy notice and a delete-account control that anonymizes the account.
- Moved the app and its service onto Cloudflare staging for testing. This page still records that production deploy has not been performed.
- Module catalog grew by about 2,700 entries gathered from manufacturers' own websites.
- Catalog data re-checked against manufacturer pages; values that could not be confirmed were blanked.
- v0.3.0-alpha.2 pre-release, the first with aligned version numbers and an automated release process.
- Began an optional helper for settling uncertain photo matches; it stays off by default and advisory.
- v0.3.0-alpha.1: upload several rig photos, review suggested module matches and confirm each yourself.
- Patch-book design engine added for styled one-page layouts and ZIP export, switched off by default.
- Visual rack builder with a size map, power-rail meters and a preview before placing modules.
- Public module explorer added, with module sizes and power draw filled in for most modules.
- Generate and validate a patch library from a defined rig, with diagrams and descriptive patch names.
- Repeatable patch-book exports, where the same rig always produces the same files.
- Rack-based recommendations and a twelve-patch reference library for a sample system.
- First working PatchHive: module and case catalog, rack builder with size and power checks, PDF patch books.

What comes next. Plans, not promises, and no dates.
- In progressRun a closed staging beta that proves the whole product on a dedicated test environment.
- PlannedFreeze a release candidate on one version and prove every export format and performance budget.
- PlannedHarden for public use with monitoring, recovery drills, abuse controls and customer-facing help.
