About this listing
The Korg Opsix MkII is a 37-key FM synthesizer with 64-voice polyphony, double the original Opsix. Its six-operator architecture goes beyond traditional FM synthesis with multiple operator modes (FM, ring modulation, filter, wavefolder, and more), giving it a wider tonal range than conventional FM synths. The operator mixer provides hands-on control of all six operators simultaneously, making FM sound design visual and immediate.
Altered FM Synthesis
Six operators with 42 algorithm configurations. Each operator can function as a standard FM oscillator, but also switch to ring modulation, filter, wavefolder, or effects modes. This "Altered FM" approach lets you create sounds that range from classic DX-style electric pianos and bells to aggressive industrial textures and evolving pads that pure FM cannot achieve.
Interface & Controls
Dedicated ratio knobs and level sliders for all six operators provide tactile, real-time control. Six data entry knobs edit deeper parameters. A step sequencer records up to 16 steps with 6 notes per step, and a motion sequencer captures up to 6 lanes of knob automation. The arpeggiator offers 7 patterns.
Effects
29 effect types across multiple categories: chorus, phaser, flanger, rotary speaker, distortion, guitar amp, compressor, delay, reverb, shimmer reverb, and more.
