8-Voice Analog Synthesizer

The Prologue is the latest flagship synthesizer from Korg, boasting a wide range of premium-grade components and cutting-edge technology, resulting in one of the most exciting synthesizers to date. This 8-voice version of the Prologue features a 49-note keybed, developed using a Japanese-made natural touch keyboard for expressive playability. This ensures optimal performance standards, with its velocity-sensitive notes providing a fluid feel. The polyphonic design features 8 multitimbral voices in total, and features 11,000 discrete electronic components working together to deliver exceptional audio fidelity. Its unique circuitry results in a powerful sound, complete with a two-pole low pass filter for enhancing the sharpness of your sounds.

New Multi-Engine

One of the most unique features of the Prologue is the newly developed multi-engine. This multi-engine is comprised of three different modes including: Noise, VPM and User. The Noise Generator mode provides four selectable settings, which is ideal for percussive sounds as well as sound effects. You can generate everything from metallic like snares to swooshing transitions noises. The VPM (Variable Phase Modulation)/FM oscillator is a new addition to that of its predecessor. It can be used to produce sharp sounds, with complex overtones, producing sounds that cannot be obtained via the analog circuitry. It offers 16 varied oscillator settings, complete with a ‘Shape’ control which you can use to achieve complex sound design. The User Oscillator settings allow you to create your own custom oscillator programs. It provides you with sixteen slots, as well as a morphing wavetable oscillator, built-in as a preset for optimal flexibility.

Bi-Timbral Support

The Prologue is design as a dual-timbre synthesizer, allowing you to play two different programs at the same time. You can also layer and split sounds to achieve unique results, as well as being able to crossfade between the main timbre and sub timbre for maximum versatility. The standard polyphonic mode allows you play chords up to 8-notes. The Mono mode is great for creating bass-orientated sounds using the sub-oscillator. The Unison mode allows you to generate thick tones that are ideal for creating leads. Chord mode allows you to trigger chords with a single note for experimentation and performance use.

Premium-Grade Digital Effects

As well as the different voice modes, the Korg Prologue also boasts a myriad of premium-grade digital effects, utilising pristine 24-bit floating-point processing. This is ideal for sound design applications, allowing you to further shape and sculpt your sounds for intriguing results. The effects section is made up from two effects unit (modulation and delay/reverb), allowing you to choose from a wide range of effects such as: Chorus, Ensemble, Tape Delay, Reverb and more. It also comes complete with user effect slots, for creating your own effect programs. In addition to the built-in effects, the Prologue also features a powerful arpeggiator. The arpeggiator boasts a four-octave range, with six different mode types including manual set.

API (Application Programming Interface)

The Prologue offers a high range of customisable settings and parameters, designed to bring out the best from your creative mind. The open API (Application Programming Interface) allows you to customise and enhance the multi-engine and digital effects section. There are 16 user oscillator slots and 16 user effects slots in total for added convenience. You can use the user slots to create your own oscillators and effects programs via the dedicated librarian software (expected for download around spring 2018).

Program Sort

The Program Sort function is designed to improve your workflow, allowing you to instantly change the order of the 500 programs for quick and easy access. You can scan through the programs and sort by category, alphabetical order or via your saved favourites. There are additional settings such as Frequent, that sort the programs in order of how many times you have used a program. The Envelope mode allows you to sort them in the order of their Envelope shape.

Design & Connectivity

The sleek and stylish design is comprised of a robust body made from aluminium and premium-grade oak. Not only does it look great but the body ensures it is built-to-last. An oscilloscope function provides visual monitoring of your waveform for added convenience. It even features a sync connection for linking to another groove machine for jamming sessions. The black aluminium front panel is reminiscent of the Minilogue, utilising the same curvature with a hairline finish. The metal knobs feature diamond-cut silver indices for maximum durability, as well as adding to the sleek aesthetic.
