How does this tool work?
This tool allows you to visualize incoming MIDI signals from your connected devices directly in the browser.
Connect a MIDI keyboard or controller to your computer. Once the browser detects the device, all transmitted commands (such as note presses, control changes, or pitch bend) will be listed in the log with timestamps and precise data values. You can clear the log at any time to keep things organized.
