Korg Prologue 8 Polyphonic Analogue Synthesizer

Product Information:

A new-generation of flagship analog synthesizer.
The ultimate multi-voice, multi-timbre, multi-engine.
prologue is a fully-programmable, full-featured, professional synthesizer. Preceded by the four-voice polyphonic minilogue and the monophonic monologue, it’s the long awaited debut of the flagship: the prologue.

prologue is a polyphonic 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 gorgeous DSP-based effects, prologue expands the variety of sounds and the possibilities for user customization.

The lineup is comprised of two models that cover musicians’ needs for not only stage use, but also studio, home, or touring use: 16-voice 61-key prologue-16, and the eight-voice 49-key prologue-8. These instruments are capable of sounds that go beyond existing analog synthesizers.

16/8-voice analog sound

The prologue is a polyphonic analog synthesizer with 8 or 16 multitimbral voices. KORG’s analog synthesizer development in recent years has culminated in the prologue, which was designed using 11,000 discrete electronic components. Although the prologue is a flagship instrument, it still retains the inviting feel and accessibility of its predecessors. It features a pure analog path, impeccable sound quality, stunning presence unlike any other poly synth, and the same intuitive interface as the minilogue and monologue, granting you intuitive access to a vast world of analog synthesis.

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. Every detail has been improved on from minilogue and monologue. Its sound covers every sonic possibility: fat basses, powerful leads, and the beautiful pads that you expect from a polyphonic synthesizer.

Newly developed multi-engine

The ingenuity of prologue goes beyond its analog design. The newly developed multi engine is provided as VCO3, adding digital waveforms and FM. This multi engine, which is equipped with three different sound engines, can be combined with the analog VCOs to expand prologue’s sonic potential far beyond that of a traditional analog synthesizer.

Noise generator
There are four types of noise generator, indispensable for percussive sounds or sound effects. Experience how digital filtering can produce direct changes in the color of the noise.

VPM oscillator
The VPM (Variable Phase Modulation) / FM oscillator was newly developed for prologue. Its metallic and sharp sounds with their complex overtones could never be obtained by analog means. With 16 types of oscillator and the SHAPE knob, you’ll be intuitively guided through complex sound design. Combine these wave shapes with prologue’s gorgeous analog filters, and prepare for sounds you never thought possible.

User oscillator
The user oscillator section lets you load oscillator programs of your own creation. Sixteen slots are provided, and one type of morphing wavetable oscillator is built-in as a preset.

Digital effects

The high-quality digital effects feature pristine 32-bit floating-point processing, and add a further polish to the sound of the prologue. With two effect units provided (a modulation effect and delay/reverb), you can choose from a wide variety such as chorus or ensemble, warm tape delay, or diverse reverbs. The user effect slots let you load effect programs of your own creation.
