Korg opsix Altered FM Synthesizer

The Korg opsix represents a new and expansive reimagination of classic digital synthesis. Much like Korg did when bringing wave sequencing back in a more powerful, more musical, and more immediately accessible way with wavestate, so was the approach to FM sound generation of the opsix, resulting in another incredibly flexible and unique synth.

The Korg opsix is an “altered” six-operator FM synthesizer. With its astoundingly accessible operator mixer and flexible sound engine that goes well beyond traditional FM, this instrument widens the potential of digital synthesizers to their utmost.

The Korg opsix is an instrument for players of all generations—modern in every way, getting back to the basics to offer you a glimpse of the future. Whether you are new to synths, looking for a completely unique addition to your sound palate, or an original FM purist, opsix will deliver on all expectations and more.

The Korg opsix is a new digital synthesizer that features our newly designed six-operator sound generator. Although the instrument has a six-operator FM sound structure like classic FM synthesizers, the opsix doesn't just reproduce their sounds—it totally reimagines them! With a diversity of waveforms, operator modes that go beyond the realm of FM, and a filter that brings together a fusion of subtractive synthesis, opsix makes tames complexities of FM so that you can focus on exploring sounds instead of programming them. Simply put, opsix offers the editing simplicity of analog synths to control the power of arguably the deepest type of digital synthesis.

Musicians today use hardware-based digital synthesizers to achieve a level of operability that just cannot be found with software-based instruments. The six sets of knobs and sliders on the opsix panel, as well as the operator mixer, are symbolic of this fact. Korg’s volca FM was the first FM reimagination that helped to bring the most dynamic parameters of FM to the surface, and we expand upon that with Korg opsix’s workflow.

The knobs and sliders with two-colored LEDs on the opsix let you quickly and clearly see the relationships between operators, whose roles change with each algorithm. This lets you make direct changes to the pitch and volume for carriers, and to the brightness of the sound or the strength of the harmonics for the modulators. These controls give you sonic control over the unpredictability of FM just by subtracting and adding sounds as if you were using a mixer or drawbars!

To add to the six operator mixers, the Korg opsix features several knobs on the right side of the panel. Use the six DATA ENTRY knobs for full editing without minimizing or summarizing any information. Taking a look at these controls, you might think back to the days when traditional FM synths were more difficult to operate. Back then, you had to move through massive numbers of pages, and couldn’t figure out where you were in the overall scheme of things. Rest easy—with the opsix, we’ve taken away these worries. You can now edit without getting lost, thanks to the combination of six graphical parameters on the large OLED display at the center, and the rotary encoders.

The HOME/ALGO page is the starting page for everything on the opsix, and features major parameters including algorithms, EGs, and effects. Use this page with the operator mixer to get started with everything you need to do.

Of course, the Korg opsix is a collection of everything appealing about FM synthesis... but that’s not all. Aside from sine waves, the opsix offers an expanded list of diverse waveforms in pursuit of sounds with even more complex harmonics, which can also be used as a subtractive synth offering simple filtering.

Operator modes on the Korg opsix are used to generate sounds that are completely outside what a traditional FM sound generator can make. The operator modes let you create sounds using modulation other than FM. The opsix offers you a much wider range of sound creation, letting you combine the five operator modes (FM, ring modulation, filter, filter FM and wavefolder) and select from a wide range of waveforms.

The 16 buttons on the bottom right-hand part of the panel glow green with the colors that evoke FM synths, while providing you with a multipurpose 16-step sequencer. With this onboard polyphonic note sequencer, you can record up to six notes per step, and edit the velocity, gate time and playback timing for each note. This lets you 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. Also, the motion sequencer of the opsix 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.

While the opsix has an easy-to-use 37-note keyboard, it also features a sequencer that rivals that of grooveboxes. Just press the PLAY button—you’ll be floored by the power that this sequencer lets you unleash.

Korg products are covered by a 1 year manufacturer warranty with the option to extend it to 3 years by registering with CMI.

Although we are not authorised to determine if any repair is covered under warranty, if the item was purchased through World of Music, then we are often the best people to facilitate the claim for you and will do so as timely as possible. Warranty does not apply to cosmetic damage or faults that are a result of user neglect. Although your mate is really handy with a soldering iron, any product modification or home repair will also result in a void warranty.

Quite often, something perceived as a fault is as simple as a faulty cable or power issue so we always suggest checking over Frequently Asked Questions on the manufacturer website first. It can be a helpful approach to getting to the bottom of a problem and save you a lot of time in getting your gear back up and running!
