Poly-61

Korg Poly-61

Released: 1982

MSRP: Y179,000 ($995US)

Synopsis:

Upgrades the PolySix to dual digitally controlled oscillators and doubles program memory, while losing the dedicated PWM LFO and noise generator. This model introduces DCOs and parameter based editing approach that continues through the DW family. Architecture Class: Conventional (subtractive).

Ebay Description:

The Korg Poly-61 is a 61 key (6 voice polyphonic) synthesizer, featuring dual oscillators (saw|pulse waveform), resonant low pass analog filter, ADSR envelope (routed to filter and volume), LFO (routed to PWM, pitch, filter, volume), arpeggiator (up/down), tape interface, and 64 editable presets.
