A desktop MIDI monitor that decodes MIDI 1.0 and MIDI 2.0 messages into Universal MIDI Packets for inspection.

Landing page captured for the 2026-10-16 issue.

For: MIDI 2.0 hardware and software developers
Worth noticing: The RAW view identifies each field’s spec name, purpose, bit position, and value, and flags non-zero reserved bits.

Field notes

Listed decoding coverage includes MIDI 1.0 and 2.0 channel voice, System Common and Real Time, SysEx7/8, MIDI-CI, mixed data sets, Flex Data, and UMP utility messages. The platform table marks Windows 11 with Windows MIDI Services as verified; Windows without that service is untested, while macOS and Linux backends are labeled developing. The Windows installer is described as supporting current-user or all-user installation without a .NET runtime.
