"WALDORF MICROWAVE 1 AND WAVESLAVE - WAVETABLE SYNTHESIZER WITH 8 VOICE EXPANDER AND ANALOG FILTERS
The WaveSlave adds 8 extra voices, doubling the polyphony!! 16 Curtis analog filters !!!! Makes the Multi programs insane!!! 16 voice true Wavetable synth!! Both units use CEM-3389 Curtis chips for the filters, the same ones used in the Prophet VS!! Both units are 110V, made for use in the US, so a power converter will be needed for world wide use. I am also including a KORG RAM CARD that adds banks C & D for programs and multis, 64 more programs and multis"
