Casio VZ-1 Synopsis

Keyboard version (a.k.a. Hohner HS-2)

Voice Architecture consists of up to eight oscillators, divided into pairs. The output of each pair of oscillators is either phase or ring modulated or mixed. Each pair of oscillators can then phase modulate the next pair or be mixed to the main output.

eBay Description

The VZ-1 is a sixteen voice, multitimbral digital synthesizer with velocity/aftertouch. It sounds similar to Yamaha FM based synths, but offers 8 oscillators per voice (with many routing options), 8 waveforms and 8 stage envelopes per oscillator. Patch memory contains 64 user locations and supports RAM/ROM cards. Performance features include sustain, volume and programable pedal inputs, along with pitch bend and two programable mod wheels, LFO and portamento.
