#MidiExplorer
Midiexplorer is a tool for analyzing and visualizing the contents of a midi file, exploring a large collection of midi files, and searching for midi files with certain characteristics in your collection. We assume that you are familiar with a midi file, you have a collection of these files on your system, and you have some programs that play those files.
