Prologue is a fully-programmable, full-featured, professional synthesizer. Preceded by the 4-voice polyphonic minilogue and the monophonic monologue, this long-awaited debut marks the Prologue as the flagship of the series. Equipped with a full-sized keyboard, prologue is a polyphonic analog synthesizer 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.8/16-Voice Analog SoundThe 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 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 expect from a polyphonic synthesizer.Newly Developed Multi-EngineThe 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 generatorThere 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 oscillatorThe 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, ’ll be intuitively guided through complex sound design. Combine these wave shapes with Prologue’s gorgeous analog filters, and prepare for sounds never thought possible.User oscillatorThe user oscillator section lets load oscillator programs of own creation. Sixteen slots are provided, and one type of morphing wavetable oscillator is built-in as a preset.Digital EffectsThe high-quality digital effects feature pristine 24-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), can choose from a wide variety such as chorus or ensemble, warm tape delay, or diverse reverbs. The user effect slots let load effect programs of own creation.User-CustomizationOpen source means that the prologue’s development is ongoing
