    Release Notes: The Style/Section editor has been changed to allow greater flexibility. There is a virtual keyboard for entering notes on the screen. There is now an option within Import MIDI tracks from File to infer chords. The Style Extractor no longer requires a leadsheet file to specify chords; extraction is done only from MIDI files. The grammar formalism contains some new constructs, including the ability to specify relative pitches (rather than just abstract notes), and other built-ins. The roadmap analysis algorithm has been changed to use harmonic tempo.
