The SX-400 is a solid 4-voice analog synth. It is most comparable to the Roland Juno 6, but has a better expression-section. The aftertouch and handwheel can trigger vibrato, cutoff and pitch at the same time, variable in speed and sensitivity. Available effects include an Ensemble (chorus) and a Portamento glide-effect. The sub & noise OSC and ensemble-switch are cool and make the SX-400 good for techno and acid too. Unfortunately there are no arpeggiators or sequencers.
