Web MIDI Tab Router by gege

TabMIDI Router is a lightweight, zero-latency browser extension that turns your browser into a virtual MIDI patchbay. Connect your favorite web synthesizers, sequencers, drum machines, and mixers opened in separate tabs or windows—without installing any desktop software, virtual drivers, or external cables.

🎹 KEY FEATURES:
• Seamless Inter-Tab Routing: Send MIDI Note On/Off, Control Change (CC), and MIDI Clock between multiple web applications instantly.
• 100% Browser-Native: Works out of the box with zero external dependencies, drivers, or OS configurations.
• Multi-Tab & Multi-Window: Effortlessly route events between distinct domains running across multiple screens.
• Echo-Free Architecture: Smart routing ensures emitting tabs never receive their own messages.
• Ultra-Lightweight: Runs silently in the background with near-zero CPU overhead and ultra-low latency (<1 ms).

🎛 HOW IT WORKS:
1. Open your compatible web audio apps in different tabs.
2. The TabMIDI Router icon automatically activates and tracks connected tabs.
3. Play a keyboard or sequence notes in Tab A—your synth in Tab B responds immediately!

🛠 FOR DEVELOPERS:
Integrating TabMIDI Router into your web audio projects takes less than 5 lines of standard JavaScript using window.postMessage. Perfect for building modular web-based DAWs, synths, and music tools.
