Korg wants its Opsix to make FM synthesis accessible for all
The six-operator digital synth puts a focus on “exploring sounds instead of programming them”

In the same way that Korg streamlined wave sequencing with its Wavestate; the synth maker hopes to simplify FM synthesis for newcomers with its latest digital synth, the Opsix.
Opsix builds on a six-operator design reminiscent of the classic Yamaha DX7 – adding to the experience more operator functions, powerful filters types and an extensive range of modulation options.

Outside of the FM tradition where operators generate sine waves, Opsix has a diversity of new waveforms and operator modes – including ring mod, filter, filter FM and wave folder.
Meanwhile, a serious lean towards comprehensible subtractive synthesis comes in the form of a filter added to the end of the chain. This comes with a selection of 11 filter types to choose from, including ones culled from the Korg MS-20 and Polysix.
With a focus on “exploring sounds instead of programming them” comes some thoughtful design considerations. An easy-to-follow operator mixer takes up a comfortable portion on the Opsix’s front panel, while a screen shows you how operators are stacked and what parameters are assigned to the six-knobs control section.
Some small but noteworthy design choices include coloured lights to indicate whether a parameter affects a carrier (red) or a modulator (purple), and how operators are represented by graphic die faces as opposed to numbers on screen (for less squinting!)

Opsix also lets you run three simultaneous effects – with 30 available types – at a time. These range from more standard effects such as EQ, compressors and choruses to more esoteric ones from rotary speakers to grain shifters and shimmering reverbs.
There’s also an arpeggiator and a 16 note sequencer per patch; the latter also offers motion sequencing for recording up to six parameter changes. Apart from that, there’s 30 notes of polyphony; a 37-note keyboard; 500 programs (200 preset, 300 user) and an almighty randomise button for generating new sounds in an instant.

The Korg Opsix launches this December with a price tag of £699.00/€799.00.
