Excellent condition, includes original power supply, though no box. Previous owner was a fellow synth technician/enthusiast, so everything works as when it walked off the showroom floor. $450.

From Vintage Synth Explorer:

This beauty from Korg combines state of the art analog physical modeling synth sounds with a very vintage Korg appearance. Yes, this sounds as good as it looks! Remember Korg’s MS-series (the MS-10, MS-20 and MS-50)? That’s right, the MS or MonoSynth series are some of Korg’s most sought after analog synths. They were some of the only compact Patchable monosynths of their time, and had a great Korg sound too. While the MS2000 is somewhat “hard-wired”, it offers just as much and more flexibility while maintaining a straight forward and hands-on approach towards old-fashioned editing via dedicated knobs, buttons and flashy lights. In place of actual patch cables and input jacks, the MS2000 features a cool “Virtual Patch” mode in which signal can be routed to various sections of the synth (ie: LFO, Filter or Keyboard Velocity) using the LCD display and paging through various screens.

The MS2000 actually comes up against the similar Roland JP-8000 and Novation SuperNova & Nova synths. Despite its amazing look, the MS2000 has some surprising limitations. It has only 4-voice polyphony so you won’t be creating very lush or complex pads and sounds with it. In spite of this, its sound is clean, crisp and very flexible. It can easily conjure up beefy basslines, sub-basses, wonderful sweeping leads, pads and hits. Classic features include a 6 pattern arpeggiator, a very flexible LFO with sample and hold and even vintage wood side-panels and printed block diagrams and programming data on the face.

Programming seems just about as classic as its look. The two oscillators offer up to eight waveforms plus noise. A great self-oscillating filter section provides 12dB high and band pass filtering and switchable 12 or 24dB low pass filtering. A typical set of Envelopes modulate the filter and amplifier. Extensive modulation is provided by the two LFOs. A 16-band Vocoder section (a la VC-10) is also on-board and it does an excellent job! There are also on-board effects which include chorus, flange, phaser, delay, distortion and EQ. It also features a “Modulation Sequence” mode which is a 16-step pattern or sequence you create in either step- or real-time and any tweaking or editing can also be recorded into the pattern to add movement to it. The MS2000 is a very well designed and flexible synth with a look and functionality that not only honors but transcends its classic predecessors. It is used by BT, Depeche Mode, Apollo 440, The Crystal Method, Placebo, the Faint, Royksopp, Adrian Belew, Jean-Jacques Perrey, Saga, Klaus Schulze, Rick Wakeman, Yes, Yesterdays, Keith Emerson and Snoop Dogg.

The MS2000R is, of course, the rackmount version of this beast. Although there is no keyboard and no real need for one, the 16 function buttons on the front of the unit can be switched into “Keyboard” mode in which they function as keys, mainly for demoing sounds while you’re programming it. This is a really great feature since most rackmount synths either don’t allow you to hear your progress from the actual unit or they only feature a one-note demo button to hear your sounds. The MS2000 is truly a well thought out instrument for musicians of any level looking for classic and new sounds within a quality digital synth with a sleek vintage look that’ll turn a few heads!
