Critic Reviews

Casio CT310 (12T Feb 84)

muzines.co.uk

The Casio CT-310 is a budget-friendly keyboard that balances fun and functionality with its auto-accompaniment features and a dozen polyphonic voice selections. While it offers inspiring bass lines and a decent range of sounds, its built-in speaker lacks the strength of an external setup, and the sound effects are basic. The absence of individual section control is a downside, limiting customization. Despite these limitations, the CT-310 provides a worthwhile experience for those seeking an economical, entertaining keyboard.

Great Preset Keyboard.

Lovely keyboard made relatively famous by Mild High Club with their song Window Pane. It's a Standard Casio Keyboard affair a few preset sounds and drum rhythms, auto chord bass and arpeggio. Its quite a hefty keyboard featuring full sized keys, the action feels quite nice for a "toy" keyboard. The sounds are nothing special, pretty standard for a Casio, but for some reason they just sound extremely good coming out of the speaker or DI, better then most Casios I've tried out. You get 8 note polyphony and 4 note when you are using the auto chord function so thankfully you are not too limited. I quite like the included vibrato and "reverb" which is just a longer sustain with a much different envelope, and usually always have them on.

The drums are nice, the kick drum is surprisingly punchy and worthy of being sampled. I'm always a big sucker for the high hat and cymbal sounds on old Casio and Yamaha keyboards, something about the metallic tinged white noise just speaks to me. The only thing I could wish for was a better snare, it is not that snappy and just feels a little loose. The preprogrammed beats are nothing to write home about, but if you had to use them they are not that bad. I really would recommend sampling the drums to use on your own, they are quite nice.
