Projects / KMidimon


KMidimon monitors events coming from a MIDI external port or application via the ALSA sequencer, or Standard MIDI 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 all MIDI messages and some ALSA messages, MIDI playback, and saving the recorded event list to a text file or SMF.

      Release Notes: The main feature in this release is loading and playing OVE files (Overture). New options have been added to request real-time priority on a MIDI input thread, and to (not) automatically resize columns while recording, which was mandatory formerly and caused some people to complain because of the amount of CPU power required. Among other fixes, there is better reporting of file loading errors and revised universal sysex messages translation.
