Casio CZ-2600S (1985)
A 61-key digital synth from 1985 with phase distortion synthesis, built-in sequencer, and rare stereo speakers — a portable CZ-series oddity
Overview
The Casio CZ-2600S isn't one of the headline acts from Casio's mid-80s synth wave, but it occupies a curious niche in the CZ family tree. Released in 1985, it shares the same phase distortion synthesis engine that defined the line, offering 8-voice polyphony and a built-in sequencer for composing on the fly. What sets it apart — and At 61 keys, it strikes a balance between portability and playability, though the keybed’s weighting, cryptically listed as "O : 5 (61 k )", remains something of a mystery without direct hands-on verification. It runs on both external power ("PSU yes") and batteries ("Bat yes"), reinforcing its design as a self-contained, mobile instrument.
