Korg Prologue Polyphonic Analog Synthesizer 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.
Features
16/8-voice analog sound
The prologue is a polyphonic analog synthesizer with 8 or 16 multitimbral voices. 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.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.User-customization
The prologue provides 16 user oscillator slots and 16 user effect slots, and users can use the prologue Librarian software to load into their prologue new oscillators and effect programs created by developers with the prologue SDK (Software Development Kit).Analog comp/booster
The exclusive VU meter is available only on the prologue-16, and indicates the newly developed master effect L.F. COMP. It’s a low end booster/compressor using an analog circuit, delivering a solid sense of presence that cannot be obtained from a simple EQ.Japanese-made natural touch keyboard
The keyboard is a high-quality Japanese-made natural touch keyboard, providing the same superb touch and feel as on KORG’s high-end workstations, and allowing a high degree of expressive power.Newly developed multi-engine
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.
