Korg DSS-1 on Ebay

The Korg DSS-1 was sort of an odd beast in that it was both a sampler and a synthesizer. You could 'draw' your own waveforms, or you could load in 12-bit samples to use as the oscillator waveforms. Probably the nicest feature on it, however, are the real analog filters which can actually be switched between 12db/oct and 24db/oct slopes (odd for a sampler). It's a beast, too, weighing in at a hefty 40 pounds.
