KMidimon monitors events coming from MIDI external ports or applications via the ALSA sequencer, and from SMF (Standard MIDI files) or WRK (Cakewalk/Sonar) files. It is especially useful if you want to debug MIDI software or your MIDI setup. It features a nice graphical user interface, customizable event filters and sequencer parameters, support for MIDI and ALSA messages, and saving the recorded event list to a SMF or text file.

• Easy to use KDE graphic user interface
• Based on ALSA sequencer. Provides one input port to be connected to other programs and devices using the usual external tools (aconnect, kaconnect, QJackCtl...)
• Customizable event filters and sequencer parameters
• Supports all MIDI messages, including System Exclusive, and some ALSA messages
• MIDI Playback of the recorded session or loaded MIDI file
• Saves to a text file or standard MIDI file the recorded event list
