MIDI Host: Router & Patchbay turns your iPhone or iPad into a zero-latency MIDI routing center built on Apple’s native CoreMIDI engine. Instead of relying on hardware patchbays, you route signals from USB or Bluetooth MIDI controllers to multiple synthesizers simultaneously in a visual interface. The app supports major hardware brands including Teenage Engineering, Roland, Korg, Akai, and Yamaha, making it practical for both compact iPad Pro USB-C setups and larger stage rigs.
The interface is deliberately brutalist and minimal — large, clear switches and no hidden menus keep routing adjustments fast and readable under stage conditions. A dedicated MIDI Panic button sends CC reset commands to all connected devices with a single tap, stopping stuck notes without requiring you to touch individual instruments. The app runs as a standalone utility rather than an AUv3 audio plugin. Alongside hosts like Loopy Pro, it handles the external MIDI hardware routing layer while the host manages audio. It does not introduce audio processing of any kind — the signal path is purely MIDI data.
