# SynthHub — where synths, AI and musicians meet: sounds, alternative firmwares and the MIDI implementation of 973 synthesizers, drum machines and DAWs, for people and their AI

> SynthHub opens a catalogue of 973 devices (1573 driver files) to people and AI agents: each device's CC, NRPN and SysEx parameters and drum sounds under readable OSC addresses (e.g. `/minilab3/pad/0/color 127 0 0`, `/drm1_mkiv/drum/kick 110`). It runs a hosted MCP server (no install, no sign-up), a browser relay that lets an agent play the user's own hardware, and trust built from real-device reports per firmware. Its engine is osc-bridge, an open-source (AGPL-3.0) OSC ↔ MIDI/SysEx bridge and MCP server written in Rust: free, single binary for Linux, macOS and Windows.

This is the entry point for language models (Claude, ChatGPT, Perplexity, Gemini) reading about SynthHub and osc-bridge. Engine source: https://github.com/roomi-fields/osc-bridge — npm: `@roomi-fields/osc-bridge` — MCP registry: `io.github.roomi-fields/osc-bridge`.

Catalogue: 973 devices from 218 vendors. Each driver states its source: ✅ tested on the device (5), 📘 manufacturer documentation (3), 📡 software OSC API (7: Ableton Live via AbletonOSC, Bitwig, Reaper, Sonic Pi, SuperCollider, Pure Data, TouchDesigner, VCV Rack), 🎛️ Electra One community presets (588), 📦 MIDI Guide community data, CC BY-SA 4.0 (376). Most drivers are not yet tested on hardware.

Commands: `osc-bridge detect` (find connected devices with the MIDI Identity Request and match drivers), `run` (bridge one device; OSC on 127.0.0.1:7777; `--osc-client` for MIDI-in → OSC; `--ws-bind` for browser clients over WebSocket), `orchestrate` (several devices, inter-device routes), `backup` / `restore` (SysEx preset librarian, .syx files), `inspect`, `lint`, `osc-send`, `osc-listen`, `mcp`.

Hosted MCP server (no sign-up): a personal address that keeps the account, https://mcp.synthhub.roomi-fields.com/u/<id>/mcp (the install box at https://synthhub.roomi-fields.com/#install gives it, with ready-made settings) — catalogue tools plus report_result (works / fails / partial, per firmware, with the device's Identity Reply) and get_trust (usage-verified, firmware-dependent, disputed…); every driver's trust at https://mcp.synthhub.roomi-fields.com/v1/trust.

MCP tools on your machine: list_devices (filters: query, vendor, kind, limit), get_device_docs, list_routes, send, get_status, detect_hardware, backup_presets, restore_presets (refuses without confirm_overwrite: true).

## Sounds and creators

- [Sounds](https://synthhub.roomi-fields.com/presets/): free sounds, kits and patterns for synthesizers and drum machines, each crediting its author with its licence (CC BY-SA 4.0 for sounds shared here; an imported sound keeps its source's, e.g. CC0, MIT, GPL-3.0). One page per sound at https://synthhub.roomi-fields.com/presets/<id>/; it loads into the device from the browser over Web MIDI. Search: https://synthhub.roomi-fields.com/presets/?query=<words>&device=<driver id>&category=<bass|lead|pad|…>
- [Creators](https://synthhub.roomi-fields.com/authors/): the sound designers and firmware authors, one page each with their sounds; an imported author can claim their page
- [M-VAVE FM-1](https://synthhub.roomi-fields.com/fm-1/): the FM-1 and its community firmwares playable in the browser (a patched fm1-emu), with every firmware's author, licence, installer and MIDI driver; their factory sounds are on SynthHub, credited to whoever made each
- [Full index for language models](https://synthhub.roomi-fields.com/llms-full.txt): every device with its parameter and sound counts, and every creator
- Agents: find_presets, get_preset and load_preset (MCP) search the sounds and load one into the user's synth through the relay

## Documentation

- [Home](https://synthhub.roomi-fields.com/): what SynthHub and osc-bridge do
- [Install osc-bridge](https://synthhub.roomi-fields.com/getting-started/): install, detect, run, send
- [Device catalogue](https://synthhub.roomi-fields.com/catalogue/): search every driver; one page per device at https://synthhub.roomi-fields.com/devices/<vendor>/<driver>/ with its OSC, CC and NRPN map
- [Connect your synth](https://synthhub.roomi-fields.com/connect/): no-install relay — open in Chrome or Edge, give the pairing code to the agent; relay_status, relay_detect, relay_send, relay_listen reach the user's hardware through the hosted MCP server
- [Build with AI](https://synthhub.roomi-fields.com/build/): add SynthHub to an AI app and ask it for an editor, a script or a MIDNAM file of any device; it reads the real MIDI implementation instead of guessing
- [Open Synth Descriptors](https://synthhub.roomi-fields.com/osd/): the open format (CC0, JSON Schema) the catalogue is written in: devices, maker profiles, shared sounds and firmwares, complementary to the MIDI standards
- [API for agents](https://synthhub.roomi-fields.com/api/): static JSON API — [index of every driver](https://synthhub.roomi-fields.com/api/v1/index.json) (source tier, firmware, coverage) and each driver file at https://synthhub.roomi-fields.com/api/v1/devices/<vendor>/<driver>.json; hosted MCP server at a personal address (no sign-up: the install box at https://synthhub.roomi-fields.com/#install gives it)
- [MCP server](https://synthhub.roomi-fields.com/MCP/): configuration and the eight tools
- [Device JSON schema](https://synthhub.roomi-fields.com/DEVICE_JSON_SCHEMA/): CC/NRPN params, SysEx commands, drum triggers, replies, OSC transport
- [Your first device JSON](https://synthhub.roomi-fields.com/TUTORIAL_FIRST_DEVICE/): write a driver in about 30 minutes
- [Changelog](https://synthhub.roomi-fields.com/changelog/): every release
