Building on the four-voice minilogue and the monophonic monologue, Korg has debuted the flaship of the “logue” lineup, the prologue. The Korg prologue is a fully-programmable, full-featured, analog synthesizer equipped with a full-sized keyboard. With powerful analog circuits that are descended directly from the earlier models of the series, together with a newly developed digital multi engine and onboard DSP-based effects, prologue expands the variety of sonic range for their Logue series.
The prologue comes in two flavors, a 16-voice 61-key prologue-16, and the eight-voice 49-key prologue-8. Both feature a pure analog path, “Logue” sound quality, and the same interface as the minilogue and monologue. The prologue uses a structure of 2VCO + MULTI ENGINE, 1VCF, 2EG, 1VCA, and 1LFO. In addition to distinctive, original circuitry, such as wave shaping to shape the oscillator’s overtones and a sync/ring switch, prologue also features a two-pole low pass filter with enhanced sharpness, drive that adds powerful distortion, and a low cut (high pass) switch.
