Korg Opsix MK2 FM Synthesizer

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.

Altered Reality

What started as a legacy synthesis has evolved into something completely different. opsix mk II 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.

Powerful Effects Processing

opsix mk II 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.

Polyphonic Motion Sequencing

opsix mk II 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 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 mk II ’s modulation possibilities are genuinely mind-blowing. With six operator modes and 40 preset algorithms, plus the ability to create your own, opsix mk II 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.

Throw the Dice

Use the Randomize feature if you’re in the mood for unexpected sonic discoveries. Press the button marked with the die icon to completely scramble the synth’s parameters, generating a new, unique sound. You can use the Randomize feature for all parameters or just for the operators, the algorithm, or the sequences.

You might strike gold with your roll, but if not, just try again or use the result as a starting point for your next new sound.
