prologue is the company’s new flagship analog synth

Korg has announced the prologue, its new flagship analog synthesizer that comes with full-sized keys and will be available in two models: the 16-voice 61-key prologue-16, and the eight-voice 49-key prologue-8.

There have been whispers about Korg’s forthcoming synth ever since the company’s VP said on a podcast last October that a new product was coming that “starts with P and contains eight letters.” The prologue is sort of a follow-up to Korg’s Minilogue and Monologue synths that were released in 2015 and 2016, respectively. And although it carries over the clean and accessible interface from this line, it’s entirely more powerful in what it can produce.

The prologue is powered by three different sound engines, which Korg says “expand prologue’s sonic potential far beyond that of a traditional analog synthesizer.” It gives incredible flexibility with audio creation via a VPM / FM oscillator for complex “metallic and sharp sounds,” a noise generator for percussion or sound effects, and a user oscillator section that is programmable, but comes with one morphing wavetable oscillator as a preset.

The prologue is polyphonic and has four different voice modes: mono (produces only one note at a time), unison (creates a thick sound by layering multiple notes and playing them as a single note), poly (play multiple notes at once), or chord (play chords with one finger). It is also a two-timbre synth, so users can layer and play two patches (sounds) at the same time, crossfade between the two, or split them entirely.

Additionally, it comes with a powerful arpeggiator that has a range of four octaves, two digital effect units (modulation and delay / reverb), two envelope generators for adjusting the dynamics of the sound, one filter, and one LFO (used to modulate a sound for creating a rhythmic pulse or sweep). There are multiple ways to navigate through and organize the synth’s hundreds of patches, including the ability to mark your favorites, or see the ones you tend to use the most.

One of the things that’s most exciting about the Korg prologue is that it has a total of 32 free slots that allow for users to load in their own oscillators and effects. Korg says there is an upcoming software toolkit to be released in spring that will allow developers to “program, customize and extend the capabilities of the multi-engine and digital effects.”

You can preorder the Korg prologue-8 today for $1,499.99 and the prologue-16 for $1,999.99. Check out a number of sound demos from the prologue below, and for more information about the prologue’s specs, visit Korg’s website.
