opsix mk II 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.
