2018 NAMM Show: Korg today officially introduced the Prologue, a multi-voice, multi-timbre, multi-engine polyphonic analogue synthesizer.
The company positions the Korg Prologue as a professional-level analog ‘flagship’ synth. It offers full-size keys, discrete circuitry, a newly developed open-source multi engine, and DSP-based effects.
The Prologue is available in either 8 voice (49 key) or 16 voice (61 key) models with multi-timbral zoning options, with Korg’s best full-size synth action, also found in the Kronos workstation.
The Prologue uses a structure of 2VCO + MULTI ENGINE, 1VCF, 2EG, 1VCA, and 1LFO. The Prologue features a two-pole low pass filter with enhanced sharpness, drive that adds powerful distortion, and a low cut (high pass) switch.
A 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 beyond that of a traditional analog synthesizer:
- Noise – There are four types of noise generators, for percussive sounds or sound effects. Experience how
- VPM oscillator – The VPM (Variable Phase Modulation) / FM oscillator was newly developed for prologue. It can create metallic and sharp sounds with complex overtones.
- 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.
The digital effects feature 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.
The Prologue offers an SDK (Software Development Kit) that allows developers to program, customize and extend the capabilities of the multi-engine and digital effects. The SDK is expected to be available for download in the spring of 2018.
The Prologue provides 16 user oscillator slots and 16 user effect slots, and users can use the Librarian software (also expected to be available for download in the spring of 2018) to load new oscillators and effect programs created by developers with the SDK (Software Development Kit).
The 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.
Here’s the official video intro:
The Korg Prologue is a two-timbre synth that allows two different programs to be played simultaneously. In addition to layer and split, the Prologue provides four voice modes: Poly, Mono, Unison or Chord, allowing the user to freely combine the 16 or 8 voices for performances.
The dual effects section includes Mod and Delay/Reverb, each with areas for user-created algorithms.
One of the most unique aspects of the Prologue is its support for user-creatable oscillators and effects. Users can program their own oscillators and effects or download code created by others to use on their own Prologue.
