Casio Cosmo Synthesizer ZZ-1 Workstation

   (0 reviews)

in the 1980s, the Casio Electronics company embarked on a project to produce a high-end audio work station that could compete with the Fairlight CMI and other systems coming to market. The Casio Cosmo system featured a combination of their ZZ-1 Phase Distortion (PD) synthesis, SK-1 audio sampling and the Casio FP-6000S computer to program the different sound modules and sequencer.

The Cosmo ZZ-1 synthesizers units, called a PDU. Are said to have been the original version of the CZ-101 synthesizer. Each PDU featured 2 oscillators and filtering, that was left off of the 101. The four note sampling units, called a SPU. Featured 12bit sampling resolution at 40 khz. With a maximum of 3 seconds sampling time. The system was also designed to include digital delay and other effects upgrades. All of these options could be ordered ala cart to be configured to the customers needs. As shown in the official literature. The debut system appears with six of the PDU synthesizers and two of the SPU sampler units along side the FP-6000S computer with a remote keyboard for MIDI control. Shown with the Casiotone CT-6000 remote keyboard.
