Editor: Chord Studio is a musical program all about chords, from simple triads to complex jazz voicings.
It is:
Educational, telling you the name of a given combination of notes, or letting you hear how a chord with a given name sounds
Practical, for printing out professional looking charts for yourself or others to play
Creative, letting you experiment with chord sounds in a unique way that would be cumbersome to do in a normal sequencer
Chord Studio can play through a sequence of chords, or save one as a MIDI file. It will also open a MIDI file, presenting it as a new chord chart.
