Casio made a significant impact on the world of synthesizers in the 1980s with its introduction of the CZ Series, which featured a unique form of digital synthesis called Phase Distortion (PD). The Casio CZ-101, launched in 1984, became an affordable and accessible alternative to more complex and expensive synthesizers, offering versatile digital sounds that were particularly well-suited to pop, new wave, and experimental music. The CZ-101’s compact size and distinctive digital tones earned it a cult following and made it a mainstay in home studios and professional setups alike. Casio’s pioneering work in digital synthesis during this era helped democratise music-making, putting powerful tools in the hands of musicians at a fraction of the cost of many contemporaries.

In addition to the CZ Series, Casio introduced the VL-Tone Series, which blended calculator-like features with basic synthesis, becoming iconic for its quirky charm and memorable sounds. The Casio Casiotone keyboards also became ubiquitous, catering to hobbyists and beginners with user-friendly features and built-in rhythms. While not always seen as high-end synthesizers, Casio’s instruments played a crucial role in shaping the landscape of affordable digital music gear, making it possible for countless musicians to explore synthesis without breaking the bank. In recent years, Casio has focused on compact and portable instruments like the Casio XW Series, which offer modern synthesis features in accessible, portable packages.
