The Prologue-16 is a polyphonic analog synthesizer with 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.
