Korg Wavestation A/D

Unit has tested in great working condition with a bit of cosmetic wear and missing knob  cap. Backlight it out on the display, however it's still legible. Includes extra RAM cart and AC power cable.

From VSE:

The Wavestation A/D is essentially a compact rackmount module of the Wavestation EX. It has the 4MB of advanced Vector Synthesis and Wave Sequencing synthesis and editing capabilities. The A/D also has a joystick controller to aid editing the Vectors. A new feature is a stereo analog input for filtering and modulating any external audio sources. They can even be used as part of the vector wave shaping, vocoder and more to incorporate it into your sound. The Wavestation A/D also has a wealth of on-board digital multi-effects for sweet synth sounds and pads!
