Inspired by the legendary mono/poly, Korg's multi/poly takes analogue modelling to new heights. Offering breathtaking analogue sounds that only digital power can provide, this revolutionary synthesizer puts the world of modular sound design into a compact, hands-on instrument. Whether you're crafting thick, layered textures or exploring experimental, cutting-edge tones, the multi/poly opens the door to endless sonic possibilities.
Combining the rich warmth of classic analogue with flexibility and control of digital, the multi/poly is the first synth to feature Korg's next-generation analogue modelling technology. Designed for musicians and sound designers alike, multi/poly delivers everything from rich, warm tones to experimental, modular-derived textures. Whether you’re sculpting classic synth sounds or exploring new frontiers of sound design, multi/poly provides the tools you need to take your creativity to the next level.
Next-Level Analogue Modelling
multi/poly features redesigned, incredibly detailed filters and oscillators, and advances in analogue modelling that take this technology to a new level. Each voice contains a Virtual Voice Card, where oscillators, filters, envelopes, LFOs, and portamento circuits are modelled to reflect analogue hardware component variations. As a result, each voice can have its own slightly different character, creating rich and naturally evolving timbres.
Just like in an analogue synthesizer, voice cards continue to play even if you’re not hearing them. Envelopes evolve naturally, meaning if you play a long pad with an extended release time, newly played notes “catch” the envelope at its current state rather than restarting from zero. Oscillators and LFOs maintain phase, while resonance continues to ring out. Pitch drift mimics the subtle instabilities of true analogue hardware.
multi/poly also includes envelope curvature presets inspired by classic synths like the Mono/Poly, MS-20, ARP Odyssey, and Prophet 5. Additionally, analogue VCAs behave differently depending on voltage, with varying thresholds for turning on and off, which has a strong impact on the Amp Envelope’s character. multi/poly models VCA responses from the Mono/Poly, MS-20, Prophet 5, Mini, Odyssey, and more, alongside a linear option.
Four Oscillators Per Program for Complex Tones
multi/poly offers four oscillators per Program, providing thick, multi-layered tones. You can choose from three types of oscillators:
Classic oscillators
These faithfully model traditional analogue waveforms with stunning accuracy. The 11 options include both single and dual waveforms, giving you rich, thick sounds.
Front-panel knobs offer control over pulse width, triangle “lean,” dual-waveform blending, and more.
Digital oscillators
Play wavetables with up to 64 steps, like vintage hybrid synths or modern Eurorack modules. Start with over 200 factory wavetables or import your own using the Editor/Librarian software for macOS and Windows. You can even import Modwave wavetables or convert wavetables from popular software formats. The 30+ Modifiers allow you to reshape wavetables, while 8 Morph Types (Stretch, Flip, Mirror, etc.) process them in real time.
Waveshaper oscillators
Inspired by West-Coast synthesis, these oscillators take simple waveforms (sine or triangle) and process them through a shaper table, producing dynamic harmonics. Use the Berkeley shaper for traditional wavefolding timbres, or choose from over 90 shaper types for a vast array of tones. The multi/poly also supports modulatable pulse width, adding richness and motion to your sound.
Additionally, the multi/poly includes a noise generator with dedicated filtering and saturation, and a ring modulator with inputs from the oscillators. You can create powerful sounds by leveraging the enhanced sync and x-mod capabilities, which expand on the Mono/Poly’s original design. Create unique tones by syncing oscillators 2, 3, and 4 to oscillator 1, or split sync and x-mod into pairs for independent control.
Advanced Modulation with Motion Sequencing 2.0
The multi/poly features Motion Sequencing 2.0, evolved from Korg’s Wave Sequencing technology. It divides Timing, Pitch, Shape, and Step Sequences into independent Lanes, each with its own loop points. This gives you the power to create intricate, evolving patterns where each note can trigger a different combination of parameters. You can modulate loop points, randomise step order, or adjust probabilities for more organic, evolving sounds.
Each Program offers four loopable DAHDSR envelopes, five LFOs, and six Mod Processors per voice, allowing complex modulation of each sound. Combine Motion Sequencing with Kaoss Physics, where you can control real-time modulation by rolling and manipulating a virtual ball on an X/Y pad for an expressive and interactive sound experience.
Dual Modelled Filters for Maximum Flexibility
multi/poly’s filters are newly redesigned to offer a range of classic and modern options. The multi/poly also includes the MS-20 LP and HP 12dB/octave Korg 35 filters, recreating the aggressive, distinctive sound of the MS-20. For gentler tones, use the SE M/P 2-pole filter, which offers continuous control for sweeping between lowpass, band-reject, and highpass, with a separate bandpass mode.
multi/poly’s filters support audio-rate modulation, allowing you to modulate filters using any oscillator or the ring modulator for bright, fizzy, and bubbling effects.
- M/Poly: A 4-pole self-resonating filter, modelled on the Mono/Poly.
- Mini: A ladder filter from a famous American mono-synth, with reduced resonance at low frequencies—perfect for bass.
- Pro: From the first programmable polyphonic synthesizer, offering strong resonant sweeps.
- Ladder HP/BP: 4-pole self-resonating highpass and bandpass filters.
Use the Drive circuit to add weight or distortion, ranging from subtle thickening to extreme saturation. You can use two filters at once in series or parallel, with each source (oscillators, noise, and ring mod) having its own balance control to crossfade between filters. Modulate the A/B balance for even more creative sound shaping.
The Power of Four
multi/poly's structure allows you to build four Layers, each containing a separate Program. This adds an entirely new dimension of sonic complexity, as you can layer up to four Programs simultaneously in a Performance. These can be used to create massive, multi-layered sounds or creative splits and velocity-triggered variations. Each Program features its own set of oscillators, filters, envelopes, LFOs, and effects, allowing you to craft detailed, evolving performances that change with every key press.
Each Program starts with four oscillators, a noise generator, and both sync and x-mod capabilities. These are processed through two independent filters, providing massive tonal flexibility. For modulation, multi/poly includes four loopable DAHDSR envelopes, five LFOs, and six Mod Processors, allowing you to create detailed and evolving sounds.
Layer Rotate for Evolving Performances
The Layer Rotate feature allows you to cycle through these four Programs with each key press, ensuring dynamic, ever-changing performances. Inspired by the original Mono/Poly’s paraphonic mode, Layer Rotate offers endless creative possibilities. You can set the Layers to trigger in random or repeating order and use them in combination with the arpeggiator for complex, mind-bending patterns.

How much is my shipping?
Shipping is automatically calculated before you submit your payment information. Simply add items to your cart and proceed to the checkout page, where you'll be offered shipping options and their prices. In the UK it's normally around £4 for order values under £150, and free above that. Shipping to mainland EU is typically between £7 and £20, depending on the shipping method and the size and weight of the order.
Do you ship to my country?
Almost certainly - the site will give you an estimate of shipping costs if you add an item to the cart and then enter your country and postcode. If you have specific requirements (such as if you prefer UPS over FedEx, for example) then let us know in advance and we'll try to work something out for you.
Shipping methods
We use a combination of Parcelforce, DPD, Royal Mail and UPS for the UK, and for international orders it's either Royal Mail, UPS, DHL or FedEx depending on where you are in the world. If you have a particular preference then try to let us know BEFORE you order so we can look into it for you. Please note that there may occasionally be additional shipping charges if you live in a remote area, depending on what surcharges are applied by the shipper. We'll get in touch to discuss this with you in such cases.
Dispatch times
For UK orders, we normally dispatch the same working day if we get the order before 15:00. If you have a really urgent situation then of course drop us an email before ordering and we'll always do our absolute best to accommodate you.
For international orders, we normally dispatch the same day if we get the order before 13:00 but again, occasionally it might be the next day before we can send it out, and sometimes FedEx or UPS may come a little earlier than scheduled which would also push an order into the next day.
Shipping times
Since April 2020 the couriers we use have suspended guarantees for shipping times, so even though we're paying them for priority services - 24-48 hours for most of the world - in practice it's often an extra day on top and sometimes it can be longer.
There is absolutely nothing we can do about this unfortunately. If you are outside the UK and it's a life-or-death situation where you absolutely MUST have that passive mult for the next day then... it may be better to find a local supplier.
Saturday shipping
If you're in the UK and you order before 15:30 on a Friday then we can send something for a Saturday delivery (NB: this applies to UK mainland addresses only). The success rate with DPD is about 95% so it's worth a punt most of the time. Please note that if you select Saturday shipping on an order placed earlier in the week, we'll wait until Friday to ship it.
Pre-orders
If a product is listed as a pre-order, it means we've ordered it from the supplier but it's not physically in stock yet. The product listing will include an estimated shipping date based on the best information we have from the supplier, but do bear in mind this is subject to change and is not a guaranteed date.
If you place an order containing a mixture of in-stock and pre-order items, we'll normally hold off on shipping anything until the pre-order item(s) have arrived, rather than splitting it into multiple shipments. If you need the in-stock items sooner, we'd recommend placing separate orders. As always, please get in touch if you have questions.
