Kawai SX-240

Released in 1984

The SX-240 (first made by Teisco, then branded by Kawai) is a 61-note 8-voice analog synth with two DCOs and a sub-oscillator per voice. It can also be switched to 4-voice mode, with 4 DCOs per voice, or to unison mode. It has a built-in chorus ('Ensemble'), and uses analog SSM filter chips. Like the SX-210 - and the Yamaha CS-80 - the SX-240 has both portamento (glide) and glissando (chromatically steps through notes).
