This docking window displays input MIDI events in real time, which can be useful for debugging your MIDI setup. To display output events, use the MIDI Output bar, which works similarly.
By default, the window shows all input received from the MIDI input device. The data can be filtered, so that only a subset of the events are shown, using optional filters which are accessible via context menu. The filtering is non-destructive, i.e. if you remove a filter, any events that were rejected by that filter reappear.
For example, to only see events on channel 10, select 10 in the Channel Filter submenu. To only see Note On messages, select "Note On" in the Message Filter submenu. To remove all filters, use the context menu's Reset Filters command.
To pause the display, select Pause in the window's context menu. Events continue to be captured while you're paused, so you won't miss any. To resume the display, reselect Pause in the context menu. The context menu also allows you to clear the event history, via Clear History.
