Casio CZ-1 Cosmo Synthesizer Keyboard

    Description
    The CZ-1 synthesizer is most advanced in the CZ series. It doubled the memory, was multitimbral, also stored splits and layers as "Operation Memories", added velocity and aftertouch sensitivity to the keyboard, along with programming parameters to control how velocity and aftertouch pressure would affect the sound.

    It features three modes 'normal' (1 tone 16 voice), 'tone mix' and 'key split' (2 tones with 8 voices each). In the 2 tone modes the chorus setting controls which tone goes to which of the left and right output channels.

    With external effects the lack of negative velocity volume control can be circumvented and velocity crossfades between tones can be achieved using the separate output channels. Page 12 of the CZ-1 operation manual explains the tone output channel settings.

    The CZ-1 also featured a back-lit display which is lacking on the rest of the series.
