ShowMIDI
ShowMIDI is a multi-platform GUI application to effortlessly visualize MIDI activity, filling a void in the available MIDI monitoring solutions.
Instead of wading through logs of MIDI messages to correlate relevant ones and identify what is happening, ShowMIDI visualizes the current activity and hides what you don’t care about anymore. It provides you with a real-time glanceable view of all MIDI activity on your computer.
When something happens that you need to analyze in detail, you can press the spacebar to pause the data and see a real-time static snapshot. Once you’re doing, press the spacebar again and ShowMIDI resumes with the latest activity.
