16 Voice 61 Key Polyphonic Analog Synthesizer

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 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.

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.
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.
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.
