Korg opsix Module Altered FM Synthesizer

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 opsix Module’s 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. In fact, hundreds of the original factory sounds include Polyphonic Aftertouch modulation. All of this makes the opsix module an excellent companion to KORG’s Keystage controller.

Rack-Mount and Desktop

The opsix module is for both desktop and rack-mount use. The panel fits into a standard 19″ width. Also, the rear jack panel allows easy access to cables even with the gear mounted directly. 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.
