Korg OPSIX-SE

The Essentials to Know About the Korg opsix SE Synthesizer

• Ultra-intuitive "Altered" FM Synthesis: 6-fader mixer to balance each operator and sculpt the timbre in real time, without getting lost in menus.
• Premium 61-key keyboard with aftertouch: more playability, more expressiveness, ideal for lively pads, edgy leads, and textures that respond to touch.
• Up to 80 voices of stereo polyphony: plenty of headroom to layer complex sounds, play rich chords, and maintain smoothness both in the studio and live.
• Robust stage format: metal chassis and hard case included for safe transport of the instrument.

An SE Variant Designed for Keyboardists and the Stage

Based on the DNA of the opsix, the Korg opsix SE carries forward the concept of modernized FM with a more comfortable 61-key format and a design more "stage-oriented." The idea is to retain the power of FM synthesis while making it more playable, more expressive (aftertouch), and more immediate to control, suitable for both production and performance.

For Which Musicians and Styles?

The opsix SE targets experienced keyboardists and sound designers who want to go beyond classic FM sounds. It excels at sharp basses, bell and metallic tones, aggressive leads, as well as cinematic and evolving pads. An excellent choice for electro, techno, ambient, synthwave, pop, and soundtrack music, with a workflow adapted to studio, live, and sound experimentation.

Features and Innovations

At the heart of the Korg opsix SE, the enhanced FM synthesis is based on a 6-operator architecture that can change roles depending on the selected mode (FM, Ring Mod., Filter, Filter FM, Wave Folder, Effect). This flexibility allows transitioning from crystalline FM to saturated, organic, or very modern timbres, with varied waveforms and modeled filters, including colors inspired by MS-20 and Polysix. Programming is accelerated by the OLED screen, direct accesses, and visual tools such as the spectrum analyzer and oscilloscope.

For creation and stage use, the instrument integrates 3 effect blocks (30 types each), a 16-step sequencer (up to 6 notes per step), a motion sequencer (up to 6 tracks), and an arpeggiator. Randomization is ideal for quickly generating patch variations and triggering ideas, while factory sounds are designed to exploit aftertouch and stereo polyphony.
