If you're looking for a synthesizer capable of recreating awesome vintage analogue sounds, then you must check out the Tarkus. The Tarkus features four sixteen step Sequencers, Arpeggiator and Multi-Effects which include Chorus, Phaser, Delay, Distortion and EQ. If you're lucky enough to own a Korg MS2000, then you can use the MS2000's control surface to edit most of the Tarkus's common control parameters.
