Inspired by the iconic KORG Mono/Poly, the new multi/poly synthesizer combines rich analog sounds with cutting-edge digital power. Building on its predecessor’s experimental features, like x-mod, sync routing, and round-robin oscillators, the multi/poly introduces next-gen analog modeling in a compact, modular-style design. With East-coast, West-coast, and wavetable oscillators, modeled filters, and innovative tools like Kaoss Physics and Layer Rotate, it offers endless creative possibilities for sound designers and musicians.
Virtual Voice Cards: A New Dimension of Analog Authenticity
One of the most exciting innovations in the multi/poly is its Virtual Voice Cards, a feature that models the subtle imperfections of analog components, creating organic variation in every note. These voice cards emulate the natural fluctuations and drift found in vintage synths, allowing each voice to evolve and differ slightly from the others—just like in real analog hardware.
This level of detail also extends to other critical elements of the sound engine, such as envelopes and VCAs. Korg has meticulously modeled the envelope characteristics and VCA responses of legendary synths like the MS-20, Prophet-5, and ARP Odyssey, giving players the ability to replicate the nuanced dynamics of these iconic instruments.
Oscillators
With four oscillators per program, the multi/poly is capable of producing thick, complex textures. The Classic oscillator mode emulates traditional analog synth waveforms with incredible fidelity, while the Digital oscillator mode brings the power of wavetables into play, offering over 200 factory wavetables that can be further manipulated using Modifiers and Morph Types. For those seeking more experimental timbres, the Waveshaper oscillator provides West Coast-style wavefolding and modulatable pulse width, adding another layer of depth to your sound design.
In addition to the four oscillators, the multi/poly includes a noise generator, ring modulator, and enhanced oscillator sync and x-mod options. This opens up a world of creative potential for crafting unique sounds that were previously only possible with large modular setups.
Redesigned Filters
The multi/poly features a suite of redesigned filters that faithfully model some of the most revered filter circuits in synthesis history. Users can choose from five different 4-pole self-resonating filters, including models based on the original Mono/Poly filter, the Minimoog’s ladder filter, and the Prophet-5’s Curtis filter. Korg has also included its famous MS-20 filters, offering both lowpass and highpass options for those seeking the aggressive, distinctive sound of the MS-20.
With dual filter slots per program, users can run filters in series or parallel, giving unprecedented control over the signal path. The multi/poly also introduces audio-rate modulation, allowing for the creation of bright, complex harmonic textures by modulating the filters with oscillators or ring modulation.

Modulation and Motion Sequencing
The multi/poly is a modulation powerhouse. With five LFOs, four DAHDSR (Delay-Attack-Hold-Decay-Sustain-Release) envelopes, and six modulation processors, the possibilities for sonic manipulation are vast. What sets the multi/poly apart is the inclusion of Motion Sequencing 2.0, a system derived from Korg’s wavestate. This feature allows musicians to create complex, evolving sequences with independent control over timing, pitch, and modulation for each lane, adding an extra layer of dynamic control.
Kaoss Physics engine
The Kaoss Physics engine, accessible via the KAOSS pad, further enhances performance by enabling real-time, gesture-based modulation. This physical interaction with sound makes the multi/poly a highly expressive instrument, ideal for live performances and experimental soundscapes.
Seamless Integration and Connectivity
For modern studios, connectivity is crucial, and the multi/poly delivers with a range of options: standard MIDI, USB-MIDI, balanced stereo outputs, and more. A damper pedal input and stereo headphone jack make it stage-ready as well. Additionally, Korg provides a comprehensive editor/librarian software for macOS and Windows, allowing users to organize and tweak their sounds effortlessly.
Layer Rotate
Inspired by the paraphonic mode of the original Mono/Poly, the Layer Rotate feature introduces a round-robin system that cycles through up to four different programs with each key press. This allows for intricate, evolving soundscapes, as each layer can be triggered in a set order, randomly, or simultaneously. When combined with the arpeggiator, Layer Rotate opens up even more creative possibilities, offering patterns and textures that evolve in complex, organic ways.
Effects and Real-Time Control
The multi/poly comes loaded with a range of high-quality effects, including reverbs, delays, choruses, and more. Its three dedicated effects slots per layer allow musicians to create polished, studio-ready sounds directly from the instrument. The multi/poly also features real-time randomization for those seeking inspiration—a single press of the “dice” button generates new sounds, adding an element of unpredictability that can lead to unexpected creative breakthroughs.
In terms of control, the multi/poly offers a tactile experience, with dedicated knobs for all key parameters. This hands-on interface, combined with Kaoss Physics, makes it easy to manipulate sounds in real time, whether in the studio or on stage.
The Korg multi/poly is more than just a tribute to a classic synthesizer—it’s a modern tool that bridges the gap between analog warmth and digital versatility. Its innovative features, such as Virtual Voice Cards, Layer Rotate, and Kaoss Physics, make it a flexible, powerful instrument for musicians and sound designers. By combining the best of analog and digital synthesis, the multi/poly offers a new playground for creativity, ensuring its place as a future classic in Korg’s legendary lineup of synthesizers.
