A free native macOS utility for monitoring MIDI messages, sending notes and controls, and routing inputs to outputs.

Landing page captured for the 2026-10-29 issue.

For: Mac musicians, MIDI tinkerers, and hardware-software setup testers
Worth noticing: Routing supports channel and message-type filters, transpose and velocity scaling, saved presets, and loop protection.

Field notes

The site shows a keyboard demo whose readout displays the three bytes the app would send, and describes shortcuts for changing octave and sending all-notes-off. A menu-bar mode is presented for checking recent messages, pausing monitoring, and switching presets; a pinned mini monitor is also described. The site states that routing continues with the main window closed while the app remains open.
