The ALSA MIDI Filter application consists of a main script, named midifilter, and supporting Perl modules, configuration files, and documentation. It runs as an ALSA MIDI client that can receive input from a source (such as a MIDI keyboard connected to the computer), perform various filtering and other functionality based on the type and content of the MIDI input, and send the result to one or more other MIDI clients.
