MidiKit is a MIDI file browser/editor and batch processor. The browser quickly displays the most significant information about MIDI files. The editor allows native SMF editing with unlimited undo/redo capacity. Finally, MidiKit allows you to apply several operations on your MIDI files by batch processing entire disks at a time.
