MidiSpy is a MIDI input logging utility. It enables you to capture all incoming MIDI events so that you can discover how your MIDI device is communicating. You can also use it to view the contents of SysEx messages.

This utility can be used by musicians to discover what settings to use for certain hardware in a sequencing application. It is also useful for MIDI software developers to aid in testing their applications.


- Supports real-time capturing of all MIDI events.

- Has a filter function so it can listen only for messages that you are actually interested in.

- Supports addition and removal of MIDI devices while the program is running/capturing. No restart required.

- View the contents of SysEx messages.

Unstable & Unsufficant

It stops working from time to time, making it very unreliable,
Copy paste does not work
Does not check for invalid midi commands.
Use MIDI Monitor instead. It's better and it's free
