Next-Level Analog Modeling

The multi/poly features redesigned, incredible-sounding filters and oscillators – and its advances in analog modeling go so much deeper. To start with, each voice has a Virtual Voice Card whose oscillators, filters, envelopes, LFOs, and portamento circuits model analog hardware component variations. The result is that each voice has a slightly different character, creating naturally rich timbres. Dial in as much or as little of this variation as you like, separately for each sound.

Just like in an analog synth, voice cards also continue to play even if you're not hearing them. Envelopes keep evolving, so that if you play a pad with a long release time, newly played notes "catch" the envelope at its current level instead of restarting from zero. Oscillators and LFOs maintain their phase, and resonance continues to ring. Each oscillator’s pitch can also drift slightly over time, modeling the slight pitch instabilities found in analog hardware.

Envelopes are an often-overlooked factor that contributes to the unique sounds of vintage synths. The multi/poly includes envelope curvature presets for the Mono/Poly, MS-20, "Mini," "Pro," ARP Odyssey, and more. Also, analog VCAs don’t respond evenly to voltage, and have different thresholds for turning on and off, which in turn has a strong effect on the Amp Envelope's character. So, the multi/poly features modeled VCA responses from the Mono/Poly, MS-20, Mini, Odyssey, and Prophet 5, as well as a linear option.

Ever tried to re-create a portamento effect from a favorite song, but couldn't find the right setting even when you switched between "constant rate" and "constant time?" Classic analog synths had different approaches to portamento, too, and so the multi/poly has six different portamento models to choose from.

Inspired by the legendary KORG Mono/Poly, the new KORG multi/poly analog modeling synthesizer delivers breathtaking analog sounds combined with extraordinary digital power and flexibility.

The original Mono/Poly boasted an unusually rich sound from its four stacked oscillators, as well as unique, experimental features like flexible x-mod and sync routing and round-robin oscillator triggering. Previously only attainable in large modular systems, the Mono/Poly delivered these features in a compact, user-friendly instrument.

The new multi/poly is the first instrument to use KORG's next-generation analog modeling technology and builds on that legendary distinctive combination of big sounds and modular-derived experimental features. It's like a polyphonic modular system in a compact, hands-on package – a limitless playground for synth players and sound designers. Create hardware mash-ups with East-coast, West-coast, and wavetable oscillators and a wide selection of newly-modeled filters. Make them come alive with models of different envelope, VCA, and portamento circuits. Virtual voice cards produce organic timbral variation. Layer Rotate triggers new Programs with each press of a key. Plus Kaoss Physics, Motion Sequencing 2.0, massive modulation, and more.

Oscillators

The multi/poly offers FOUR oscillators per Program, for unusually thick, complex tones. Each can use the Classic, Digital, or Waveshaper oscillator types. The Classic oscillator models traditional analog synth oscillators with stunning fidelity and effortless thickness. 11 options include both single and dual waveforms, for modeling synths that generated multiple waveforms at once. Front panel knobs give you hands-on control of pulse width, triangle "lean", dual-waveform blend, and more.

The multi/poly also expands on the original Mono/Poly's powerful oscillator sync and x-mod capabilities, for timbres otherwise only possible with a large modular setup. Create unique sounds with Oscillators 2, 3, and 4 simultaneously following Oscillator 1 for sync, x-mod, or both at once. Alternatively, split either function into oscillator pairs with separate control.

Dual Modeled Filters

All of the multi/poly's filters are newly redesigned, including an amazing suite of vintage filters with authentic euphonic saturation. To start with, there are five different 4-pole self-resonating models. M/Poly provides the strong, sweet sound of the classic Korg Mono/Poly. Mini is the ladder filter from a beloved American mono-synth; resonance is reduced at low frequencies, critical for producing those classic bass sounds. Pro is from the first programmable polyphonic synthesizer, with strong resonant sweeps all the way down. Finally, Ladder HP and BP are 4-pole self-resonating highpass and bandpass filters, respectively.
