The Ultimate Fusion of Power & Performance
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.

Six in One Synthesis

Opsix SE is FM-based, but the similarities to the classic synthesis end there. The Altered FM architecture delivers sounds across a vast spectrum, far wider than any single synthesis has been able to cover before, thanks to new sound components; new waveforms, filters, shaping, effects, LFOs, envelopes, modulations, and more, all translating to its broad assortment of sounds.


Removing parts of the sound to get the sound you want; the most widely-used synthesis. Opsix uses up to six envelopes and multi-modelled filters to achieve many cutting-edge and classical analogue synthesis tones.


Rerouting signal paths to change the sound. A spin through the Algorithm section will dramatically reshape the sound by changing how the signal routing between the operators work together, and no patch cables are needed.

Analogue (Modelling)

Analogue-style controls and plenty of stackable waveforms take you from digital to analogue-sounding in no time. Enjoy deep basses, crisp leads, thick pad sounds, fuzzy brass tones, and so much more.


Adding intentional distortion to the waveforms to achieve aggressive overtones that are either harmonic or inharmonic. This will help you achieve gritty, bitey tones dripping with character.


Stacking waveforms and blending their harmonics is key to an expansive range of harmonious, dissonant, and tension-driven sounds. With six operators available, the complete FM experience is possible, including the ability to go back in time for classic sounds you have heard throughout recording history.

Classic FM

Last but certainly not least, Opsix’s highly flexible and powerful architecture starts with true six-Operator FM. As a result, it easily delivers signature sounds you have surely heard on thousands of hits from the ‘80s on through today, and with far more polyphony than other standalone FM synths available today.

Automated 16-step sequencing

Opsix SE features an incredible step sequencer that rivals groove boxes for flexibility and power. Press the PLAY button on any sound and experience the complexity of the sequences! Every Program has its unique sequence stored with it or create your very own.

You can record up to six notes per step and edit each note’s velocity, gate time, and playback timing. Create long phrases or make subtle shifts in timing to emulate strums or drum rolls, something that’s not possible on a typical 16-step sequencer. The motion sequencer of the Opsix SE also lets you record changes of up to six parameters, creating smooth motion changes in sound within a phrase or building rhythms that change dramatically with each step.

Monster Modulation Matrix

The Opsix SE’s modulation possibilities are genuinely mind-blowing. With six operator modes and 40 preset algorithms, plus the ability to create your own, Opsix SE offers you dynamic sonic options.

This synthesis is supercharged with the processors that come at the end of the signal chain. The MOD section works separate from the operators, with three EGs and three LFOs; and 12 virtual patches for a wide variety of routing possibilities. Use these features for a huge range of modulation to create swirling soundscapes or add rhythmic motion to your sounds.

Powerful effects

Opsix SE provides three blocks of 30 types of high-definition effects that you can use together to enhance your sounds even further. There’s everything from a great mix of usable standard effects like chorus, phaser, delay, and compressor to some world-class shimmering reverbs that will elevate your sound to the next level.

Opsix Librarian

The Opsix Sound Librarian lets you view and organize data on an Opsix SE connected to a computer via USB, and transfer sound data back and forth between the Opsix SE and the computer.

The Opsix SE takes this even further.

Premium metal design

The Opsix SE showcases a slim body, specifically designed for this instrument and features a striking brown painted aluminium control panel, paying homage to vintage machines. Together with the vivid, illuminating LEDs, it brings a vibrant energy to any stage performance. The side panels, painted in a sleek black metal, amplify the overall aesthetics for a luxurious finish.

Built to play

Opsix SE was born out of the desire to play this incredible synth with both hands. Equipped with Korg’s premium 61-note natural-touch keyboard, the Opsix SE offers the same outstanding tactile response as Korg’s top-tier workstations. Aftertouch puts unparalleled control of all the exceptional Opsix sounds at your fingertips. Of course, we’ve modernised the factory Performances for aftertouch and introduced some fresh ones to the mix as well. In fact, most of the Opsix SE programs have been revised to make full use of aftertouch, extended keyboard, and polyphony.

Total illumination

At the heart of every sound is Opsix SE’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. Changing the position of these controllers 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 SE so unique, just like the sounds it offers.

Direct 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 analogue-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 analyser and oscilloscope that gives you visual feedback via the screen on the music you’re making.
