POLYPHONIC  |  BACK

Korg PolysixThe Korg Polysix is a six voice programmable polyphonic synthesizer released by Korg in 1981.

The synthesizer's main features are six-voice polyphony (with unison and chord memory voice assignment modes), 32 memory slots for patches and cassette port for backing up patches, and an arpeggiator.

On its release it was, along with the Roland Juno 6 released around the same time, one of the first times a polyphonic analog synthesizer was available at a cost effective price 'for the masses'. It cost about twice as much as the competing Juno 6 but had far more features and 'real' VCOs in place of the Juno's DCOs. It also had on-board patch storage and back up which the cheaper Juno lacked until the upgraded Juno 60 model.

Korg developed the Polysix with an eye on the Sequential Circuits Prophet 5, trying to provide some of the features found on the more expensive synth in a compact, reliable and much cheaper design. While not as powerful, it used SSM2044 4-pole voltage-controlled , giving the Polysix a warm, rounded and organic sound.

Although the Polysix only had one oscillator per voice, it also featured built chorus, phaser and 'ensemble' effects (using a 'bucket brigade' analog delay line design), to provide a fuller sound

The Polysix had a straightforward synthesis architecture. Each voice had one oscillator with sawtooth wave, variable pulse wave, or PWM outputs. The PWM section had its own LFO. In addition, there is a sub-oscillator that allows the addition of a square wave either one or two octaves below the main VCO pitch.

The filter has controls for cutoff frequency, resonance, envelope amount and keyboard tracking. The envelope control has a center zero, letting the user select either a normal or an inverted envelope. The envelope is an ADSR type. The VCA can be operated from either the envelope or a gate signal.

The mixed sound of all the voices can be sent to an effects section, which offers three modulated delay-based effects (Chorus, Phase or Ensemble setting). This acts to fatten the sound considerably, and was a key feature at the time of release.

The LFO (known here as a 'modulation generator') is a simple triangle wave that can be routed to the VCO, VCF or VCA. It has a variable delay before it is triggered.

Although built into a substantial (and heavy) chipboard case, the Polysix has some reliability problems. Like other programmable synthesizers of the era, it had a rechargeable nickel-cadmium battery that powered the memory when the unit was switched off. The original batteries are now well past their designed lifespan and thus prone to failure, leaving the instrument unable to recall user designed patches from its memory. If the battery is not replaced, it can leak and corrode the circuits. Unfortunately for the Polysix, this battery is mounted on the main processor board and corrosion here can be fatally damaging to the circuitry of the instrument.

Some instruments of its era had begun the move towards digital technology by using DCOs or microprocessor-generated envelopes. The Polysix, however, used a separate analog VCO, VCF and envelope generator for each voice. Whilst this might have benefits for the richness of the sound, the extra complexity also brings greater tuning problems and more possibilities for failure.

The Polysix keyboard used a light plastic keyboard with conductive rubber contacts. These contacts are often the source of 'dead' keys on the keyboard. This is probably the most common problem on old Polysix units, and one shared with some other Korg instruments that used the same keyboard, such as the Poly-61 and Mono/Poly.
