...Chords and major/minor keys can be extracted from the MIDI file using a configurable tool that analyses the MIDI file. Chords, keys, and time signatures can also be created or updated manually - this allows you to play along with an audio source without requiring a MIDI file.
The program contains a sequencer-style display that can be used to control the volume, panning, muting, solo'ing and patching of the tracks of the MIDI file.
