A Full-Spectrum Sound Experience

opsix mk II is a digital synth like no other. Based on the sound engine of the original opsix, the number of simultaneous voices and voicings has been expanded to an astounding 64 voices. The result is superior performance and precise control.

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.

And, it is fully compatible with the sounds and samples from both the original opsix and the opsix Native software, including numerous high-quality libraries.

Evolved to an astounding 64 voices

The opsix mk II has 64 voices, twice as many as the original 32 voices, allowing users to enjoy tone editing without having to worry about the number of simultaneous voices. In addition, the operator-mixer section, the most distinctive feature of this product, has been accented with a new image color, green.

Get Illuminated with the Operator Mixer

At the heart of every sound is opsix mk II's Operator Mixer - a simple set of six faders and knobs that invite exploration. Each part lights up red to indicate carriers or blue for modulators. Manipulating them opens up new sound-shaping possibilities to breathe fresh life into your musical ideas. This straightforward, hands-on workflow is part of what makes opsix mk II so unique, just like the sounds it offers.

Direct Hands-On Control

Whether you're tweaking a preset or building a patch from the ground up, the six data entry knobs on the right give you quick access to the parameters you need and seamlessly sync with the large OLED display, giving you a clear, focused direction to your workflow. Coupled with the mixer, it makes creating fresh sounds super easy and, most importantly, fun!

Select from a full range of analog-style filters, from the radical Korg MS-20 low-pass/high-pass filter to the powerful yet smooth KORG Polysix low-pass filter that gives your sound a vintage feel. There are also two or four-pole low-pass, high-pass, band-pass, and band-reject filters with resonance.

There's even a built-in spectrum analyzer and oscilloscope that gives you visual feedback via the screen on the music you're making.
