This is a vintage digitally controlled analog synth hybrid keyboard in near perfect condition, and comes with the original hard case and foam inserts. The case has some small dings and tears, but overall is also in good condition. These were manufactured by Korg between 1984-1985, and feature a six note polyphonic hybrid synthesizer with two single-cycle digital waveform oscillators and one analogue lowpass filter per voice. If you are looking at it, you probably know what it is. It's a really sweet little vintage synth, with some really cool settings and voices on it. It has everything from synth lead patches to "helicopter," "jet plane," and even specific patches called "B. Jean" and "Africa"! If you're looking for a budget vintage synth to handle that 80s vibe, look no further.
