The Korg opsix MKII is a digital synth like no other. The opsix Operator Mixer simplified FM synthesis for the first time, making it not just comprehensible but also controllable. With the addition of extra synthesis capabilities and programming, it offered a more efficient workflow and an even richer sound.

Now, Korg has created a new form of opsix, the module. This model supports MIDI 2.0 property exchange and poly aftertouch, and is an excellent companion to Keystage. It’s also fully compatible with the sounds of the original opsix, opsix mk II, opsix SE, and opsix native software, as well as numerous excellent third-party libraries, keeping the updated sounds and software fresh. The new 19" rack-mountable enclosure has the same controls as the keyed models, yet is easily transportable and fits neatly into any studio or desktop production system.

MIDI 2.0 Property Exchange and Polyphonic Aftertouch support

With the latest software updates, all models of opsix, hardware and software, now support MIDI 2.0 Property Exchange. Hundreds of the original factory sounds have been updated to include Polyphonic Aftertouch modulation (Channel Aftertouch is supported as well). All of this makes the opsix module an excellent companion to KORG's Keystage controller.

Rack-Mount and Desktop

The opsix module is cleverly designed for both desktop and rack-mount use. The panel is redesigned to fit into a standard 19" width, and the rear jack panel is recessed to allow easy access to cables even with gear mounted directly above. With desktop setups, brackets offer a choice of panel angles: flatter for performing standing up, or more upright for working while seated in your studio.

Many musicians have requested a module version of the opsix. Now that components are once again available after a long period of supply-chain disruption, KORG is pleased to make that request a reality
