The 8-voice Korg Prologue is the flagship polyphonic analogue synthesiser that builds upon the success of the Minilogue and Monologue synthesisers, combining multi-voice, multi-timbre, and Multi-Engine technology to create a professional-quality instrument that's capable of satiating the most advanced user, but with an interface that a novice will find inviting.

The synthesiser's architecture uses two VCOs + Multi-Engine (VCO3), a 12 db/per octave filter, two envelopes, a VCA, and an LFO. The Multi-Engine is equipped with three sound generation devices including a noise generator, a variable phase modulation (VMP/FM) generator, and a user oscillator, which allows you to load your own oscillator programmes via a free and soon-to-be-released editor/librarian. The two-pole, low-pass filter with enhanced sharpness adds drive with powerful distortion, as well as a low-cut (high-pass) switch. Its sound covers almost every sonic possibility: fat basses, powerful leads, and the lush pads that you expect from a polyphonic synthesiser.

Additional features include four voice modes, a powerful arpeggiator, and a 24-bit digital effects engine, which provides two effect slots (a modulation effect and delay/reverb). Choose between a wide variety of effects such as chorus or ensemble, warm tape delay, or diverse reverbs. The keyboard is a high-quality, Japanese-made, Natural Touch keyboard, providing the same professional-quality touch and feel as on KORG’s high-end workstations. The instrument's enclosure is constructed from a black aluminium front panel with oak wood sides, and high-quality metal knobs. The Korg prologue ships with an IEC power cord.


  • 8-voice analogue synthesiser circuit
  • 49-note, Japanese-made, high-quality, Natural Touch keyboard
  • Multi-Engine Equipped with 3-Types: Noise, VPM, and user
  • High-quality digital effects
  • Open source software that can be customised by the user
  • Bi-timbre support
  • Voice modes that allow voices to be flexibly recombined
  • Arpeggiator equipped with a variety of types and range settings
  • Programme Sort allows rapid access to 500 programmes
  • Oscilloscope function shows the waveform visually
  • Tough and stylish body made of aluminium and wood
  • Sync with another groove machine to enjoy jam sessions


  • The Multi-Engine is provided as VCO3, adding digital waveforms and FM via three different sound engines, which can be combined with the analogue VCOs to expand prologue’s sonic potential far beyond that of a traditional analogue synthesiser
  • Noise Generator: Four types of noise generators create percussive sounds or sound effects. Experience how digital filtering can produce direct changes in the colour of the noise
  • VPM Oscillator: The VPM (Variable Phase Modulation) / FM oscillator offers a metallic and sharp sound with complex overtones that could never be obtained by analogue means. With 16 types of oscillator and the Shape knob, you’ll be intuitively guided through complex sound design
  • User Oscillator: Load oscillator programmes of your own creation. Sixteen slots are provided, and one type of morphing wavetable oscillator is built-in as a preset

Voice Modes

  • Four Voice Modes
  • Poly: Operates as a poly synth with up to 8 voices. Turn the Voice Mode Depth knob to switch to Duo mode, in which the instrument operates in unison as a poly synth with up to 4 voices
  • Mono: Operates as a mono synth with sub oscillator
  • Unison: Operates as an all-unison mono synth
  • Chord: Plays chords


  • Digital Effects: High-quality digital effects feature 24-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 programmes of your own creation

Programme Sort

  • The programme sort function lets you instantly change the sorting order of the 500 programmes
  • Eight Programme Sort Methods
  • Prog Num: Sort by programme number
  • Category: Sort by programme category
  • Alphabetical: Sort programmes alphabetically
  • Like: Sort by programmes that you “liked”
  • Frequent: Sort by how frequently you used the programme
  • Envelope: Sort by envelope shape
  • Random: Sort randomly
  • Live Set: Sort programmes registered in a live set


  • The prologue is a two-timbre synthesiser that lets you play two different programmes simultaneously. In addition to layer and split, you can use crossfade to smoothly transition between the main timbre and sub timbre


  • The powerful arpeggiator opens a world of limitless inspiration. It provides a four-octave range, and six arpeggiator types. From phrases that could not be performed on a keyboard to sequence-like sound designs, the arpeggiator can play a versatile array of roles
  • Types:
  • Manual
  • Rise
  • Fall
  • Rise Fall
  • Random
  • Poly Random

User Customisation

  • Open source means that the prologue’s development is ongoing. It provides 16 user oscillator slots and 16 user effect slots, and you can use the "soon-to-be-released" dedicated librarian software to create your very own oscillators and effect programmes, and load them into prologue

Australian Shipping Via DHL
DHL offers a great express shipping service to Australia from New Zealand. We are proud to be able to offer express shipping to main cities on the east coast of Australia, within the same timeframe ( If not quicker ) than local Australian courier companies. Prior to the Covid-19 outbreak, service standards for these main centers was overnight. However these services have been impacted greatly, and as such the overnight service has been suspended. Overnight shipping will likely resume once things have returned to normal.

Qualifying main centers include:

  • Brisbane
  • Sydney
  • Adelaide

Whilst this service is extremely efficient and will likely be delivered within 1-2 days 99.9% of the time, it cannot be guaranteed. In the case where something were to go wrong with your delivery and it doesn’t arrive within the specified time frame, in most cases it will be delivered by the next day.

While not all major cities are eligible for overnight delivery, they still benefit from this great service. Other centers throughout Australia will have a typical delivery ETA of 2-4 days. (Excluding rural delivery address where this ETA can be extended to an additional three or more days).

If you require urgent shipping and you don’t reside in one of the cities stated above, please contact us and we can find a solution that works best for you.

Please Note: Shipping via DHL is not available to PO boxes and/ or parcel boxes etc.
