Midi Router Client

Midi Router Client is a cross‑platform application that lets users route and transform MIDI data in real time. It creates virtual MIDI ports, monitors incoming streams, and can remap events such as converting control‑change messages to pitch‑wheel data or vice versa. The software supports routing between any combination of sources and destinations, including server‑to‑server connections, while maintaining minimal latency.

Advanced users can build custom controls, including program‑change dropdowns, NRPN‑to‑CC mappings, and transpose or harmonize functions. Presets can be triggered by any MIDI event, enabling complex, repeatable setups without manual reconfiguration. The interface is built with Electron and Qt, and the core logic is implemented in C++ and TypeScript.

The tool runs on Linux, macOS, and Windows and is distributed under the MIT License. Documentation, installation guides, and source code are available online, and the project is maintained as stable, targeting users who need flexible, low‑latency MIDI routing and manipulation.
