An earlier version of the SX-240, it's very similar in design and construction but doesn't have a sequencer or MIDI. It was manufactured only from 80 to 82 was the first Kawai synth sold in North America. It's oscillators are digitially controlled, but the rest of it is pure analog. Among its drawbacks: oscillators (saw, square and pulse) cannot be mixed but are either on or off, though the noise source is mixable. Sine waves can only be attained by making the VCF feed back on itself. The synth has no sliders, everything is controlled by a single large knob which increments parameters from 0 to 99, except those which are either on/ off. This allows a great deal of fine tuning, but limits editing to one parameter at a time. The LFO can be linked through virtually every component (DCO, VCF, VCA, EGs) and can be disabled / enabled in all components simultaneously. Patches can be downloaded and uploaded to and from a tape. The sounds are impressive, warm, fat very analogue. Though I may buy other synths I wouldn't trade this for anything and its the centerpiece of all my work.
Comments About the Sounds:
