Critic Reviews

Casio CZ-230S (IM Jul 86)

muzines.co.uk

The Casio CZ-230S is a versatile yet somewhat unfocused synth. Its Phase Distortion synthesis offers impressive sound creation, with 100 preset sounds that range from rich orchestral to unique effects. The PCM drum section adds a programmable touch, but lacks the individual equalization of dedicated drum machines. While it's a good option for portable composition, its mini keys, absence of auto-accompaniment, and lack of multi-timbral MIDI control limit its potential. As a jack of all trades, the CZ-230S provides diverse features but doesn’t excel in any particular area, making it suitable for casual users rather than serious musicians.
