Rethink everything you know about FM synthesis.

 

The 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 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 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.

 

True six-operator FM synthesis, and more

 

The 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.

 

 

FM exploration, easier than ever

 

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 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!

 

Full editing with the DATA ENTRY knobs

 

To add to the six operator mixers, the 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.

 

 

Five operator modes that expand FM synthesis

 

Of course, the 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 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.

 

40 preset algorithms and user algorithms

 

An algorithm is a combination of different operator roles and connections. The opsix goes far beyond classic FM synthesizers by offering 40 preset algorithmsand then goes on to offer a user algorithm function for exponentially greater sound possibilities which lets you construct and arrange an algorithm from scratch.
