The Z3000 MK2 is an analog voltage controlled oscillator with a built-in digital pulse counter. It displays constant pitch data at a refresh rate of one update per second in three different modes. Each mode can be accessed using the Mode Switch. This unique feature puts the Z3000 MK2 into a class of its own as a VCO, bringing new capabilities of complex sound synthesis to the analog realm. In addition, it simplifies the setup of multi-oscillator voices by allowing pitch intervals to be set by sight.
