The Casio FZ-1 is an impressive sampler/synthesizer keyboard from 1987. Its offerings at the time were very professional features. In an 8-voice polyphonic full 61-note keyboard synthesizer you get a 16-bit digital sampler with variable 9kHz to 36kHz sampling rates. 1MB of memory expandable to 2MB could provide a maximum time of almost 2 minutes sample time at 9kHz. Up to 64 samples can be held in memory and placed across the keyboard. Graphic editing on the big LCD screen provides intuitive and easier editing of your samples with tuning, truncating, looping and much more. It also has eight outputs and analog-like 8-stage filters (DCF) and envelopes (DCA).
