This model has 8 note polyphony, as well as one-finger chords. Interesting to note, like other casios of the era, the single-finger chords produce a timbre completely different from whatever is instrument is selected on the main keyboard. Put another way it does not matter if you have selected 'flute' or 'pipe organ', the single-finger chords sound the same for either selection. However, this model has 5 timbre settings for the chords, each one slightly different in character. I do like the sound of the single-finger chords - very electronic.

There are twelve totally crap rhythms, with bass, chord, and arpeggio accompaniment that no one in their right mind would ever use.

Round the back you have 9 volt dc in, headphone socket, line out, sustain and foot pedal sockets.

Though not versatile in any way, it has a full size keyboard (though without velocity) and can be picked up dirt cheap. Though only a few good sounds, compared with fm and pcm keyboards that came after this, this has much more character. It would be ideal for someone looking to add a keyboard to band on very, very tight budget (under £10. Otherwise ignore it.

For the circuit-benders amongst you, there are trimmers located inside the case the effect the analogue drum sounds. There is a tuning trimmer at the back (100R), and I also wonder if the vibrato, reverb, and sustain settings could be manipulated?
