70s synthesizer that works fine but I haven't been playing. It has a lot of constructed in beats and synthesizes a bunch of instruments. The various instruments sound truly cool, however they are fairly pure tones that do not seem like the real instrument. A couple of the higher secrets do not work. Not the world's most serious instrument, however absolutely a lot of enjoyable. It sounds something like the organs you hear in the background in a lot of 70s stuff.
