Visualize on a virtual piano how to play a chord. You select it in choice lists and keys are highlighted in order to show you where to put your fingers. All the chords are here: from Cm to D#(-5)add9 !Inversions are also displayed. They can be scored, played and MIDI saved. The scales (major,Blues...) can be played as well. Another module is the chord analyser: It tells you which chord is played according to the keys pressed on the virtual piano or a MIDI keyboard connected. The third module is the chord sequencer: Create and save your own patterns with chords. Export you creations as MIDI files ! A great utility for pianists.
