Description :
Inspired by the legendary KORG Mono/Poly, the new KORG multi/poly analog modeling synthesizer delivers exciting analog sound combined with extraordinary digital power and flexibility.
It has already received recognition as one of the best synthesizers of the year.
Next Level Analog Modeling :
Multi/poly features redesigned, incredible-sounding filters and oscillators – and its advances in analog modeling go much deeper. For starters, each voice has a virtual voice map whose oscillators, filters, envelopes, LFOs, and portamento circuits model the variations of analog hardware components. The result is that each voice has a slightly different character, creating naturally rich timbres. Customize as many variations as you like, individually for each sound.
Like an analog synth, the voice maps also continue to play even when you can’t hear them. The envelopes continue to evolve, so if you play a pad with a long release time, newly played notes “catch” the envelope at its current level rather than restarting from zero. The oscillators and LFOs maintain their phase, and the resonance continues to play. The pitch of each oscillator can also drift slightly over time, simulating the slight pitch instability found in analog hardware.
Envelopes are an often overlooked factor that contributes to the unique sound of vintage synths. Multi/poly includes envelope curvature presets for the Mono/Poly, MS-20, “Mini,” “Pro,” ARP Odyssey, and more. Additionally, analog VCAs do not respond uniformly to voltage and have different on and off thresholds, which in turn greatly affects the character of the amp’s envelope. So multi/poly includes modeled VCA responses from the Mono/Poly, MS-20, Mini, Odyssey, and Pro, as well as a linear option.
Have you ever tried to recreate the portamento effect from a favorite song, but couldn’t find the right setting, even when switching between “constant speed” and “constant time”? Classic analog synths also had different approaches to portamento, which is why multi/poly offers six different portamento models to choose from.
Oscillators :
Multi/poly offers four oscillators per program for incredibly dense, complex tones. Each can use the Classic, Digital, or Waveshaper oscillator types. The Classic oscillator models traditional analog synth oscillators with stunning accuracy and effortless thickness. The 11 options include both single and dual waveforms for modeling synths that generate multiple waveforms simultaneously. The front panel knobs give you hands-on control over pulse width, triangle “tilt,” blending of two waveforms, and more.
The digital oscillator reproduces 64-step wavetables, like those found in vintage hybrid synths and modern eurorack modules. Start with over 200 factory wavetables or load your own. Import modwave wavetables directly or convert wavetables from popular software formats. Use over 30 modifiers to change the way the tables are loaded, resulting in subtle or extreme timbre changes, and 8 morphing types such as Stretch, Flip and Mirror to process them in real time.
Waveshaper offers a “West-Coast” approach, where simple waveforms (sine or triangle) are processed through a shaper table. Gain modulation in the shaper creates glassy, dynamic harmonics. Use the Berkeley shaper for traditional Wavefolder tones, or choose from over 90 other shaper types. Multi/poly also adds modulated pulse width, a unique twist, for another dimension of richness and movement.
In addition to oscillators 1-4, there is a separate noise generator with dedicated filtering and saturation, and a ring modulator with inputs from all of the above.
Multi/poly also extends the powerful oscillator sync and x-mod capabilities of the original Mono/Poly for timbres that are 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. Alternatively, split any function into pairs of oscillators with separate control.
Filters with two models :
All multi/poly filters have been redesigned, including a stunning array of vintage filters with authentic euphony. To start, there are five different 4-pole self-resonating models. The M/Poly delivers the big, sweet sound of the classic Korg Mono/Poly. The Mini is a ladder filter from America’s favorite mono synth; resonance is reduced at low frequencies, which is critical for creating those classic bass sounds. The Pro is from the first programmable polyphonic synth with strong resonant sweeps all the way to the bottom. Finally, the Ladder HP and BP are 4-pole self-resonating high-pass and band-pass filters, respectively.
The MS-20 LP and HP 12dB/octave self-resonating “Korg 35” filters lovingly recreate the distinctive, aggressive tonal signature of the classic Korg MS-20. The SE M/P 2-pole filter is softer in character and features continuous control for switching between low-pass, band-stop, and high-pass filters, as well as a separate band-pass mode.
You can also shape and refine with a full complement of linear, resonant 2-pole and 4-pole low-pass, high-pass, band-stop and band-stop filters. Or go beyond with KORG’s unique Multi Filter, which creates modulated blends of multiple modes simultaneously.
All of these filters support frequency modulation for bright, fizzy, and bubbling effects that grab attention. Use any of the oscillators or the ring modulator as a modulation source, and even mix with the noise generator for more chaotic tones. In addition to the built-in saturation of the vintage filters, the Drive post-filter anti-aliasing circuit allows you to add more weight and grain to taste, from a slight thickening to a strong distortion.
Finally, you can use any two of these filters simultaneously, in series or in parallel. Programs have two filter slots, A and B. Each source, including four oscillators, noise, and ring modulation, has a balance control that crossfades between the two filters, opening up a wide range of creative possibilities. For example, send one group of oscillators through an M/Poly filter and another through an MS-20 low-pass filter. Create a classic highpass->lowpass daisy chain, but route one or more oscillators around the high-pass filter. Because this is a continuous crossfade, not just a switch, you can modulate the A/B balance for unique effects. The filters can also be run in stereo, with separate panning for each source.
