Big in Japan… and everywhere
Before releasing the famous MS line of monosynths, Keio Electronic Laboratories (under the KORG brand) introduced the Polyphonic Series of analog synthesizers. The largest and most expensive was the massive PS-3300, a legendary synthesizer produced from 1977 to 1981. It is considered one of the rarest analog synthesizers, with only about 50 pieces produced. Thanks to its semi-modular design, flexible architecture, and penchant for rich, sonic tones, the PS-3300 is often considered the holy grail of polyphonic analog synthesizers.
The PS-3300’s unique architecture set it apart from the few polyphonic synthesizers of its time. It had three independent “signal generator” panels, each of which was essentially a full-fledged polyphonic synthesizer. Each of these panels included 12 independently configurable oscillator banks with a divider, as well as independent discrete VCFs, envelope generators and VCAs for each note. This made it possible to simultaneously play all 48 keys of an external keyboard with independent articulation. Dual LFOs and triple voltage-controlled resonators for each oscillator further shape its signature tone. The dedicated master panel contains a mixer with a VCA for each of the three voice panels, a sample and hold, an additional envelope generator and two control voltage processors. In addition, it provides extensive modulation capabilities through 67 front panel input/output connectors. Overall, the PS-3300 was so powerful and revolutionary that even Bob Moog was impressed, declaring it “the ultimate synthesizer for fat sounds.”
The high production cost of the PS-3300 meant that only the wealthiest musicians could afford it, adding to its rarity and mystique. Its wide and bold sound, described as an orchestra of synthesizers, has made it a sought-after instrument among professional musicians and collectors alike. Its use by pioneering artists such as Vangelis, Jean-Michel Jarre, Aphex Twin, Kraftwerk, Klaus Schulze, Keith Emerson and Space has further cemented its popularity over the decades. Korg introduced the PS-3300 for $7,500 in 1977, and it’s now so rare and desirable that one example has sold for nearly $100,000 in 2021.
