Korg Opsix SE Synthesizer – 61 Key Plus a Korg Case – Shop Demo

The Korg opsix SE Altered FM Synthesizer takes FM synthesis to an entirely new level, combining the power of advanced digital sound design with an intuitive, hands-on workflow. Built around Korg’s innovative Altered FM sound engine, the opsix SE goes far beyond traditional FM synthesis, allowing musicians to create everything from classic electric pianos and bells to evolving pads, cinematic textures, powerful basses, aggressive leads, and experimental soundscapes. With its premium 61-note natural-touch keyboard featuring aftertouch, robust all-metal construction, and expanded 80-voice stereo polyphony, the opsix SE is equally at home in the studio and on stage.

At the heart of the opsix SE is the intuitive Operator Mixer, featuring six illuminated faders and knobs that make programming FM synthesis faster and more visual than ever before. Unlike traditional FM synthesizers, the opsix SE allows each operator to function in multiple synthesis modes, including FM, Ring Modulation, Filter, Filter FM, Wave Folder, and Effect, opening up an enormous range of sonic possibilities from analog-style sounds to complex digital textures.

The powerful sound engine is complemented by three multi-effects processors, over 30 high-definition effects, a flexible 16-step polyphonic sequencer, three envelopes, three LFOs, and a comprehensive modulation matrix with virtual patching. The built-in randomisation function can instantly generate entirely new sounds, making the opsix SE an inspiring tool for composers, producers, and sound designers.

The premium hardware features a 61-key velocity-sensitive natural-touch keyboard with channel aftertouch, precision-weighted metal knobs, a large OLED display, balanced audio outputs, MIDI, USB connectivity, and an exclusive custom hard case for safe transport. Compatible with sounds created on the original opsix and the opsix Native software, the opsix SE delivers a complete professional synthesis workstation for modern musicians.
