The PT-80 consists of a 2 octave monophonic keyboard with the sounds: piano, harpsichord, organ, violin, flute, clarinet, trumpet and celeste. The small keys on the left side is an auto chord section that is synchronized to the rhytm section. The rhytms are: Rock, disco, 16-beat, 2-beat swing, 4-beat swing, samba, bossanova, beguine, slow-rock, march, tango, waltz.

The rhythms are good and a useful thing is the ability to make fill-ins. If you, for instance, have choosen a disco rhythm and it is running, then press the disco button again and the fill-in comes.

Another feature of this model is the changeable ROM-pack that contains 4 melodies. These melodies can be played by the instrument alone or as a two way act: The instrument supplies the accompaniment, you do the melody.
