Drumstick MIDI Monitor logs MIDI 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.
