Description
<h1 style="text-align: justify;"><strong>KORG multi/poly</strong> is a new generation digital synth with <strong>analog physical modeling</strong>, inspired by KORG's classic <strong>vintage Mono/Poly</strong> which at the time combined rich timbres and experimental features typical of modular synthesizers. Thanks to modern digital technology, <strong>multi/poly</strong> produces extremely realistic analog timbres, combining computational power, high polyphony, and versatility, with an articulated synthesis structure based on <strong>Programs</strong> each with <strong>4 oscillators</strong>, <strong>noise, two filters, envelopes, modulations, and Insert effects</strong>. In turn, <strong>4</strong> Programs can be included in a <strong>Performance</strong> with <strong>Motion Sequence 2.0</strong> and <strong>Kaoss Physics</strong> functions that add further movement and timbral complexity.</h1><p><img alt="KORG multi/poly è un synth digitale a modellazione fisica analogica di nuova generazione ispirato al classico Mono/Poly vintage di KORG che combinava all’epoca timbriche di grande spessore e funzioni sperimentali tipiche dei sintetizzatori modulari." src="/images/uploads//Multi_Poly_1200x630_01.jpg" title="KORG multi/poly è un synth digitale a modellazione fisica analogica di nuova generazione ispirato al classico Mono/Poly vintage di KORG che combinava all’epoca timbriche di grande spessore e funzioni sperimentali tipiche dei sintetizzatori modulari." /></p><h2 style="text-align: justify;"><strong>KORG multi/poly key features</strong></h2><ul> <li>Hardware <strong>mash-up</strong> capabilities with classic analog, digital, wavetable, and wave-shaper oscillators, a selection of new generation physical modeling filters, portamento, envelopes, and VCAs.</li></ul><ul> <li>Each <strong>Program</strong> includes four oscillators, a noise generator, two filters and three insert effects, plus a versatile modulation path with four looping DAHDSR envelopes, five LFOs, six Mod Processors, three key-tracks, and multi-lane Motion Sequencing 2.0.</li></ul><ul> <li>Each <strong>Performance</strong> can contain four Programs at a time, adding master reverb and equalization, two additional Mod Processors and Kaoss Physics.</li> <li><strong>Layer Rotate</strong> function activates new Programs with each key press.</li> <li><strong>Motion Sequencing 2.0</strong> performs individual sequences for each voice.

The original Mono/Poly boasted an extremely rich sound thanks to its four stacked oscillators, as well as unique and experimental features such as versatile x-mod and sync routing and round-robin oscillator triggering. Previously only achievable in large modular systems, the Mono/Poly offered these features in a compact and easy-to-use instrument.</p><p>The new Multi/Poly is the first instrument to use KORG's next-generation analog modeling technology and is based on the highly effective combination of features derived from modular synths, such as having a polyphonic modular system in a compact and practical instrument, ideal for musicians and sound designers. You can create combinations of East-coast, West-coast, and wavetable type oscillators with newly designed filters, modulated by envelopes, VCAs, and portamento. While virtual voice cards produce natural timbral variations, with the Layer rotation function that activates new Programs with each key press, and also: Kaoss Physics, Motion Sequencing 2.0, effective modulations further animate each sound making it more interesting.</p><h3><strong>Superior analog modeling</strong></h3><p>The multi/poly features newly designed filters and oscillators with an extremely effective sound. Each voice, in fact, has a <strong>Virtual Voice Card</strong> whose oscillators, filters, envelopes, LFOs, and portamento circuits faithfully reproduce the variations of analog hardware components. The result is that each voice has a slightly different character, producing rich and natural timbres. This variation can be adjusted as desired independently for each sound. As in an analog synthesizer, the Virtual Voice Cards continue to sound even if not heard, as do the envelopes. This way, for example, playing a Pad with a long release time, newly played notes latch the envelope at the current level instead of starting from scratch. In the same way, oscillators and LFOs maintain their phase and resonance also continues to sound. The pitch of each oscillator can also drift slightly over time, reproducing the subtle pitch instabilities found in analog hardware.</p><p><img alt="Il multi/poly è dotato di filtri e oscillatori di nuova concezione e dal suono estremamente efficace.

The multi/poly includes presets in the envelope curves of: Mono/Poly, MS-20, "Mini", "Pro", ARP Odyssey, and more. Additionally, analog VCAs do not respond uniformly to voltage and have different thresholds for turn-on and turn-off, which in turn has a strong effect on the character of the Amp Envelope. Therefore, the multi/poly features VCA responses modeled after: Mono/Poly, MS-20, Mini, Odyssey, and Prophet 5, as well as a linear option for the Amp Envelope. Have you ever tried to recreate the Portamento effect of a favorite song, but couldn't find the right setting even by switching from "constant rate" to "constant time"? Classic analog synthesizers also had different approaches to Portamento, which is why multi/poly offers six different portamento models to choose from.</p><h3><strong>Multi/poly Oscillators</strong></h3><p>Multi/poly has FOUR oscillators for each Program, allowing for dense and complex timbres. Each oscillator can use <strong>Classic, Digital, or Waveshaper</strong> modes. Classic faithfully reproduces traditional analog synth oscillators, with a choice of 11 options including single and dual waveforms, to emulate those synthesizers that generated multiple waveforms simultaneously. Front panel knobs allow for practical control of Pulse Width, triangular "Lean", dual waveform blending, and more.</p><p>The <strong>Digital</strong> oscillator produces <strong>wavetables</strong> with up to 64 Steps, like vintage hybrid synthesizers and modern Eurorack modules. Over 200 factory Wavetables are included, and you can upload your own using the Editor/Librarian software for macOS and Windows. You can directly import modwave wavetables or those converted from popular software. Over <strong>30 Modifiers</strong> can change how tables are loaded, achieving many timbral nuances from the most delicate and subtle to the most extreme, while 8 types of Morph such as: Stretch, Flip, and Mirror process them in real time.</p><p><strong>Waveshaper</strong> offers a "West-Coast" approach, where simple waveforms (sine or triangle) are processed through a <strong>Shaper</strong> table. Gain modulation in the shaper creates crystalline and dynamic harmonics. You can use the "Berkeley" Shaper for traditional wavefolder timbres or choose from over 90 other Shaper types. The multi/poly also allows you to modulate the Pulse Width (square wave pulse width), to add an additional dimension of richness and movement. For each oscillator, an independent noise generator is also available.</p><h3><strong>Dual Modeling Filters</strong></h3><p><img alt="Tutti i filtri del multi/poly sono di recente progettazione, e comprendono una suite di filtri vintage con saturazione eufonica. Sono disponibili cinque diversi modelli con Auto-Risonanza a 4 poli, con la timbrica classica del Korg Mono/Poly" src="/images/uploads//Schema-01-Filtri_1200x630.jpg" title="Tutti i filtri del multi/poly sono di recente progettazione, e comprendono una suite di filtri vintage con saturazione eufonica. Sono disponibili cinque diversi modelli con Auto-Risonanza a 4 poli, con la timbrica classica del Korg Mono/Poly" /></p><p>All multi/poly filters are newly designed and include a suite of vintage filters with euphonic saturation. Five different models with 4-pole Auto-Resonance are available, featuring the classic Korg Mono/Poly timbre. Mini is the Ladder filter from the renowned American monophonic synth; resonance is reduced at low frequencies, an essential characteristic for producing typical bass sounds. Pro was modeled after the first programmable polyphonic synth, with resonant and prominent sweeps across the entire range. Finally, Ladder HP and BP are 4-pole self-resonating high-pass and band-pass filters, respectively.</p><p>The MS-20 LP and HP 12dB/octave "Korg 35" self-resonating filters reproduce the characteristic aggressive timbre of the classic Korg MS-20, while the 2-pole SE M/P filter has a more delicate character and features a continuous control that allows switching from low-pass to band-reject to high-pass, as well as a separate mode for band-pass. It is also possible to shape each sound with a complete set of linear and resonant 2- and 4-pole low-pass, high-pass, band-pass, and band-pass filters. Or, stepping outside the box, use KORG's exclusive Multi Filter, which creates a modulatable mix of multiple filters simultaneously.</p><p>All filters are also modulatable and allow for distinctive and dynamic timbres. It is also possible to use each oscillator, or the Ring Modulator as modulation sources and also add the Noise Generator to obtain "chaotic" sounds. Finally, it is possible to use any two filters simultaneously, in series or in parallel. Programs have two filter slots, A and B. Each source, including the four oscillators, noise, and ring Mod, has a balance control that fades from one filter to the other, allowing for a wide range of creative options. For example, you can send one group of oscillators through the M/Poly filter and the other through the MS-20 low-pass filter. Create a classic serial high-pass->low-pass chain, but route one or more oscillators around the high-pass. Since this is a continuous crossfade, and not a simple switch, you can modulate the A/B balance for unique effects. Filters can also operate in stereo, with separate panning for each source.</p><h3><strong>Multi/poly Structure</strong></h3><p><img alt="Ogni Program comprende quattro oscillatori più un generatore di rumore, ring mod, sync e x-mod. Questi vengono processati attraverso due filtri indipendenti e modulati con quattro inviluppi DAHDSR, cinque LFO e sei Mod Processor.

These are processed through two independent filters and modulated with four DAHDSR envelopes, five LFOs and six Mod Processors. In addition, there is Multi-Lane Motion Sequencing 2.0 and three studio-quality Insert effects. But this is just a single Program. Up to four Programs can be layered to compose a performance. The transition between each Program is in Round-Robin style with Layer Rotate (rotation between Programs), both when playing from the keyboard and when using the arpeggiator. The Kaoss module creates further fluid and evolving modulation with simple gestures on the X/Y Pad. The four Mod knobs on the panel offer intuitive and immediate control over different parameters. The final touch to each Performance is given by two other Mod processors, the Master Reverb and the EQ.</p><h3 style="text-align: justify;"><strong>Layer Rotate</strong></h3><p style="text-align: justify;">The multi/poly has four Layers, each containing a Program. With these, it is possible to create <strong>Layer, Velocity, and Keyboard Split</strong> sounds. Layer Rotate is inspired by the original Mono/Poly's paraphonic mode, which cyclically moved between the four oscillators; this function now adds a new possibility: Round-Robin among all Programs. By setting each Layer with different Programs, it is possible to alternate them with each key press, playing them in cyclic or random order. Activate one, two, or three Programs for each Step of the cycle, and you can use Layer Rotate with the arpeggiator to obtain very interesting patterns.</p><h3><strong>Modulation and control</strong></h3><p style="text-align: justify;">Multi/poly has a panel rich in knobs and controls that invite exploration. Oscillators, filters, envelopes, LFOs, and effects are all at your fingertips. The four programmable Mod knobs allow you to customize by assigning your preferred parameters; the knobs can be used to modify each timbre in real time and save the result. The Hold button allows you to sustain notes or chords indefinitely while exploring the front panel controls or playing other instruments. If you add Kaoss Physics and the Pitch Bend and Modulation wheels, you always have multiple expressive possibilities in real time. Finally, almost all front panel knobs and most on-screen parameters can be modulated, for a total of over 5,500 modulation destinations. It is even possible to modulate individual Steps of the Motion Sequence; eight Mod processors allow you to transform modulation signals using quantization, smoothing, shaping, and more.</p><p style="text-align: justify;"><img alt="Le Set Lists permettono l'organizzazione delle esecuzioni con il multi/poli, con accesso immediato durante il concerto o le prove." src="/images/uploads//Multi_Poly_1200x630_03.jpg" title="Le Set Lists permettono l'organizzazione delle esecuzioni con il multi/poli, con accesso immediato durante il concerto o le prove." /></p><h3><strong>Motion Sequencing 2.0</strong></h3><p style="text-align: justify;">Motion Sequencing 2.0 is an evolution of wavestate's Wave Sequencing 2.0. Timing, Pitch, Shape, and four sets of Step Sequence values are separated into "Lanes," each with its own Loop start and end, and a deeper level of phrase and modulation recording. Each time the sequence advances, the individual Lanes are combined to create the output. For example, a Step Sequence value can correspond to a different duration, pitch, and shape each time it is played. It is possible to modulate the loop points of each Lane separately for each note, using velocity, LFOs, envelopes, Mod knobs, or other Controllers, so that each note of a chord can sound differently. In the Lanes, it is also possible to randomize the order of the Steps each time they are executed. In the same way, individual Steps can be skipped randomly, with a modulatable probability from 0 to 100%.</p>The result is a natural, changeable, and fully controllable sound.
Kaoss Physics
Kaoss Physics simulates a ball rolling on a surface and bouncing off walls. The surface can be tilted in any direction. A bump of variable height/depth and position attracts or repels the ball. Adjustable friction slows the ball's movement, and adjustable time controls the speed of the entire model. All these features are modulatable and can be changed in real-time. To start the ball, simply touch the x/y pad with a finger, or launch it automatically using another modulation source. It's also possible to directly control the ball by keeping your finger on the pad. The ball's position generates eight modulation signals, which can be used to control any modulation destination: X and Y positions, distance from the center, angle from the X-axis, and finally separate signals for +/- X and +/- Y. The walls can slow the ball, as if they were padded, or accelerate it, like pinball bumpers. The walls can also be removed completely, so that the surface wraps around to the opposite edges, like in a vintage arcade game. The modeled environment can create specific modulation effects. For example, a centered Bump with negative height can be used, so that modulation values always return to 0. Or a Bump with positive height can be placed on one side or corner, to push modulation values away from that area. The result is an interactive controller that amplifies your physical gestures, transforming them into complex musical signals.
Production-Ready Effects
multi/poly offers a complete chain of high-quality effects. Each Layer has three dedicated effects, plus a send to the Master performance reverb, followed by a Master parametric EQ. In addition to standard effects like compressors, EQs, choruses, flangers, phasers, and stereo delays, distinctive processors are available such as: Wave Shaper, Talking Modulator, Reverse Delay, Multiband Mod Delay, and Overb (from OASYS and Kronos), as well as effects modeled after VOX guitar amplifiers, VOX wah, Vintage Distortion, CX-3 Rotary Speaker and Vibrato/Chorus, tape echo, and a collection of classic guitar pedals.
Editor/Librarian Software
The editor/Librarian for multi/poly allows you to edit and organize sounds via computer (macOS or Windows). For communication, it uses the high-speed USB port and functions as if it were a second front panel, so there's no need to synchronize or transfer data. Animations show the effects of modulation in real-time: a great help for programming.
Set Lists and Smooth Sound Transitions
Set Lists allow the organization of performances with multi/poly, with immediate access during concerts or rehearsals. Smooth Sound Transitions allow played notes and effects to continue naturally even after selecting a new sound, without annoying interruptions.
Built to Last
Multi/poly is an instrument built with a professional design and durable, high-quality materials. The keyboard is responsive and has a consistent touch, knobs and switches provide a solid feel and appropriate resistance, the sturdy front panel is made of aluminum, and the wooden side panels contribute to the synth's overall look, which echoes the color scheme of the original Mono/Poly.
Connections
Multi/poly has balanced stereo outputs for connecting to any recording or monitoring system, while the stereo headphone output is ideal for private playing or on-stage monitoring. MIDI (DIN type) jacks ensure connection with other equipment using this protocol, while USB supports Class-Compliant MIDI with Windows and macOS computers.
