Design
The CZ-1 utilizes special processing chips designed to support Casio's Phase distortion synthesis architecture. Phase distortion synthesis achieves complex, evolving timbres through the distortion of phase angles in digital waveforms.
Context
The CZ series was launched in 1984, positioning digital synthesis as more accessible and easier to program than Yamaha's FM synthesis, particularly in comparison to the DX7. The CZ-1 was the flagship model of the series.
Market
The CZ-1 is known to develop key contact problems over time. Replacement slider caps are available for the commonly missing CZ series sliders, and parts may be sourced from American Perfit. These machines are normally reliable and remain affordable on the used market.
