midimon

is a small and easy to use MIDI monitor. Once started it will create two virtual MIDI ports. One for reading and one for writing. These ports can be connected to and from any other ALSA MIDI port on Linux systems or — if it works on Mac too — on MAC OS X systems. Internally the MIDI messages are forwarded from the input (RtMidi input) to the output (RtMidi output) port and displayed in clear text on standard output.
