A Web-Based MIDI 2.0 Monitor

This paper presents a publicly available MIDI monitor. The application provides a web interface to list both MIDI 1.0 and MIDI 2.0 messages and aims to offer an easy-to-read interpretation of standardized message parts. In this sense, particular attention is paid to the SysEx messages that implement MIDI-CI communication in the context of MIDI 2.0. The tool was developed through the Web MIDI API, a standard proposal by the W3C Audio Group currently supported by most web browsers, in particular the Chromium-based ones and Mozilla Firefox. Possible uses range from diagnosing issues with MIDI devices and connections to investigating MIDI 2.0 concepts in educational scenarios.
