ShowMIDI

ShowMIDI is an open-source multi-platform GUI application to effortlessly visualize MIDI activity.

Instead of wading through logs of MIDI messages to correlate relevant ones and identify what is happening, ShowMIDI visualizes the current activity and auto-hides what you don't care about anymore. It provides you with a real-time glanceable view of all MIDI activity on your computer.

ShowMIDI is designed to be always on, using the spacebar or play/pause button you can pause the flow and focus on a data snapshot with the latest state of any MIDI entity.

ShowMIDI can be ran as a standalone application that automatically detects all your MIDI devices, or as an AUv3 plugin in your DAW or host to visualize MIDI data in your sessions.
