KORG multi/poly - 37-key analog modeling synthesizer with four oscillators per Program, Kaoss Physics, and Motion Sequencing 2.0

The KORG multi/poly is a professional analog modeling keyboard synthesizer inspired by the legendary Mono/Poly, but brought to a new era by an extremely flexible hybrid architecture. It combines 60 voices of polyphony (as preset) with a 37-key semi-weighted keyboard that is velocity- and release- sensitive, and integrates creative tools such as Kaoss Physics , Motion Sequencing 2.0 , Layer Rotate , and a massive modulation system covering thousands of destinations.

Each Program features four oscillators ( Classic , Digital/Wavetable , and Waveshaper types), noise , ring mod , extended sync / x-mod , and two simultaneous (series/parallel) modeled filters with a range of vintage emulations—KORG MS-20, Mono/Poly, “Mini” and “Pro” ladder, 4-pole HP/BP, Multi Filter, and more—plus post- drive anti-aliasing. Virtual voice cards reproduce analog-style component variations (oscillators, filters, envelopes, LFOs, and portamento), generating an organic, slightly different character for each voice. The engine is completed by a layered effects section (3 inserts), a master reverb , and a 4-band parametric EQ .

Main features

• Keyboard : 37 semi-weighted keys with velocity and release velocity .
• Polyphony : up to 60 voices (variable according to the complexity of the sound).
• Program Structure : 4 oscillators (Classic / Digital wavetable up to 64 steps with table import / West-Coast type Waveshaper), noise with filter and saturation, advanced ring mod , sync and x-mod ; 2 simultaneous filters (series/parallel), 4 chainable DAHDSR envelopes , 5 LFOs , 8 modulation processors and 3 insert effects per layer.
• Layers & Performances : Stack up to 4 Programs in a Performance with Layer Rotate ( round-robin layering), splits, and splits .
• Next-level analog modeling : Virtual Voice Cards (per-voice variation), classic synth envelope curves (Mono/Poly, MS-20, “Mini”, “Pro”, ARP Odyssey…), VCA models (Mono/Poly, MS-20, Mini, Odyssey, Prophet-5 and Linear) and 6 portamento types .
• Creation in motion : Multi-channel Motion Sequencing 2.0 and Kaoss Physics for fluid modulations from the X/Y.
• Massive Modulation : Over 5,500 potential destinations per Performance; supports Aftertouch and Poly Aftertouch via external MIDI.
• Effects : compressors, EQs, wah , choruses/flangers/phasers (vintage and modern), Talking Modulator , Tape Echo , Reverse/Multiband Mod Delay , Overb , Rotary CX-3, VOX amps, classic distortions, etc.
• Connectivity : 6.3mm TRS L/MONO and R outputs (impedance balanced), 6.3mm headphones , sustain pedal (no half-pedal support), MIDI DIN In/Out and USB-B class-compliant (MIDI).
• Set Lists and SST : Set Lists for organizing sounds and Smooth Sound Transitions for seamless changes.
• Includes soft carrying case and power adapter.

Benefits for the musician

• “Big” sound ready for mixing : combination of 4 virtual VCOs per Program, dual filters and studio-quality effects with reverb and master EQ.
• Fast live work : dedicated controls (4 Mod Knobs , wheels, Kaoss), Set Lists and Layer Rotate for evolving textures and complex patterns.
• Unlimited sound design : wavetable import, wavefolding , modular-style sync/x-mod routing, and over 5,500 modulation destinations.
• Analogue printing, digital freedom : hardware-style voice variation, classic VCA/portamento/ADSR models, and stable tuning.

Use cases

• Direct : 4-layer performances with smooth splits and transitions; balanced PA/monitoring outputs.
• Studio and production : multi-track motion sequences, audio frequency modulation filters, signature effects (Overb, Rotary, Tape Echo).
• Sound design : creation of your own wavetables and integration with the editor/library for macOS/Windows.

Frequently Asked Questions

• Can I import my own wavetables ? Yes, using the Editor/Librarian for macOS/Windows; it also supports ModWave tables with conversion.
• Does the sustain pedal support half pedal operation? No, the DAMPER connector does not support half pedal operation.
• Does it come with a case? Yes, it comes with a soft case along with the power adapter.
