Casio

Casio is a Japanese multinational corporation that is known for its wide range of consumer electronics products, including calculators, watches, and digital pianos. They also have a history of producing synthesizers, starting in the 1980s.

Casio first introduced synthesizers in 1980, with the release of the Casiotone series, which were portable, affordable and aimed at home users. These early synthesizers were simple, often featuring preset sounds and basic sequencing capabilities.

In 1983, Casio released the VL-Tone, which was the first synthesizer to feature a digital signal processing (DSP) chip, which allowed for more complex and realistic sounds. This was followed by the release of the Casio CZ series in 1985, which were more advanced synthesizers that featured phase distortion synthesis and multiple waveforms.

In the late 1980s and early 1990s, Casio released a series of digital synthesizers, including the FZ-1, FZ-10M, and FZ-20M, which were known for their high-quality sounds and powerful sequencing capabilities. These synthesizers became popular among electronic musicians and producers and were used by several famous artists.

In the late 1990s, Casio discontinued its line of synthesizers, focusing instead on other consumer electronic products. However, the company has recently re-entered the synthesizer market with a new line of portable and affordable synthesizers, such as the Casio XW-P1 and the Casio XW-G1, aimed at home users and performers

Overall, Casio has a long history of producing synthesizers, starting with simple and affordable models in the 1980s, evolving to more advanced and professional models in the 1990s. While they stopped producing synthesizers for a period of time, they have recently returned to the market with new portable and affordable models.
