SynthHub - Behringer synth control over WebUSB / WebMIDI

Live at synth-hub.elevatech.xyz - runs entirely in your browser.

The Web App that manages every Behringer synthesizer over USB - an alternative to Behringer's SynthTribe desktop editor. Edit device settings, run the step sequencer, record MIDI, and check firmware status for 71 Behringer models directly in your browser, with no install and no drivers.

Supported synths include: Behringer 2600 (Blue Marvin / Gray Meanie), TD-3, TD-3-MO, RD-8, RD-9, RD-6, Model D, Poly D, Pro-1, Pro-800, MS-1, MS-5, Model 15, UB-Xa, Odyssey, Crave, K-2, Kobol Expander, MonoPoly, Wasp Deluxe, Edge, Spice, Proton, JT-4000, JT-2, CAT, Solina, Vocoder VC340 and many more.

• Device discovery over WebUSB (Behringer vendor id 0x1397).
• Device control over WebMIDI SysEx (USB-MIDI) - settings, sequencer.
• 71 device models, 130 USB product IDs.
• Per-device settings UI (dropdowns / toggles / spin boxes / radios / sliders), a full sequencer editor (ratchets, per-step velocity / gate / probability, directions, live MIDI-in recording), CV calibration references and poly-chain.
• Installable, offline-capable PWA. Everything runs locally in the browser; no server, no telemetry.

Quick start

cd app
npm install
npm run dev        # http://localhost:4321

Open in a Chromium-based browser (Chrome / Edge / Brave / Opera) over localhost or HTTPS - WebUSB and WebMIDI require a secure context. Click CONNECT USB, pick your Behringer synth, and its controls appear.

If SynthHub saves you a desktop install (or a stuck note), you can buy me a coffee. It keeps the device coverage growing.
