Yes. You load the melody in ABC format, create the chords, and it will then play a complete MIDI. There are different chord options, and if you don't like the chords it suggests, you can replace them and regenerate the notes for the chords. The manual give details of the more complex chords you can use, and also on ways to adjust the range of the notes used for the chords. One of my longer term aims is to make the chords appropriate to the instrument selected, e.g. real Guitar chords.
