This synth was traded on 5-21-2026.
Traded: Korg Multi/Poly in minty condition. Includes the original box, soft gig bag, power supply, and quick start guide with download code. This unit is essentially brand-new. Listed as mint/excellent out of an abundance of caution in case there is something extremely minor we missed.
This unit ships free in the original inner and outer box.
The Multi/Poly is often pitched as a synth designed to recreate the past, but in reality it is about expanding what modern synthesis can be. Built by Korg as a forward-looking platform, it pairs four fully independent parts with deep modulation, per-layer sequencing, and a massive sound-design surface that rewards exploration. Multiple envelopes and LFOs per part, extensive modulation routing, hands-on controls, and a wide array of high-quality onboard effects make it a machine that evolves with your ideas instead of boxing you into a decade or a genre. This is a synth for building new textures, new workflows, and new sounds, not nostalgia. The engine is very deep and at times challening to work with, but so very much worth wrapping your head around. Absolute killer. We would not be selling this if Captain Black did not already have a desktop version.

Synthesis Type: Advanced digital synthesis platform combining virtual analog, wavetable, phase modulation, and modern digital oscillator models.
Polyphony & Structure: Multi-layer architecture with up to 4 fully independent parts, each capable of its own sound engine, modulation, effects, and sequencing (voices are dynamically allocated across parts).
Oscillators: Multiple oscillator models per part:
Analog-style oscillators with classic waveforms.
Wavetable and digital oscillator models for evolving and complex timbres.
Noise and utility sources for texture, percussion, and modulation.
Oscillator sync, ring modulation, and advanced cross-modulation options.
Filters: Multiple filter models per part:
Classic lowpass, highpass, bandpass, and band-reject responses.
Selectable character models inspired by vintage and modern designs.
Resonance capable of aggressive coloration and self-oscillation.
Dedicated filter envelopes for precise contour shaping.
Modulation: Extremely deep modulation system:
Multiple envelopes and LFOs per part for complex motion.
Flexible modulation routing allowing nearly any source to target.
Per-part modulation sequencing for rhythmic or evolving changes.
Hands-on control over modulation depth and destinations.
Sequencing:
Per-part step sequencing for notes, motion, and modulation.
Supports layered, polyrhythmic, and evolving sequences.
Syncable to internal or external clock.
Effects: Extensive onboard effects system:
Multiple insert effects per part plus global effects.
High-quality modulation, delay, reverb, distortion, and spatial effects.
Effects are fully modulatable for dynamic sound design.
Performance & Interface:
Velocity-sensitive keyboard with expressive response.
Hands-on front-panel control designed for sound design and live performance.
Clear display and structured interface for deep editing without menu diving.
Connectivity:
Stereo audio outputs.
MIDI In/Out/Thru for integration with hardware and DAWs.
USB for MIDI and system connectivity.
Headphone output for silent operation.
Sound Character: Capable of massive layered pads, aggressive modern leads, intricate rhythmic textures, and evolving soundscapes that go far beyond traditional subtractive synthesis.
