UPDATE: Korg has since released full details of the opsix Altered FM Synthesizer – read up on all the details here!



A juicy leak for all you Korg fans out there: The eagle-eyed bloggers at our sister site salvaged photo and specifications of what appears to be the upcoming Korg opsix from the webcache of a Danish dealer,! We’ve known about the opsix since NAMM 2020, but the images of the new version – assuming they are genuine – take the design in an exciting and more compact new direction. Check out the images below. So how will Korg’s new FM synth sound and feel? We can’t wait to find out. Also, images of a new SQ sequencer and the much anticipated ARP 2600 mini have also appeared. Great stuff, Korg!

Korg opsix leak

Leaked image allegedly of the (as yet unreleased) Korg opsix

Our friends at reported earlier in the week that the first units are already in circulation, presumably with beta testers, sound designers and perhaps VIPs or influencers. If that’s true (the article didn’t cite specific sources), the official announcement may be coming soon.

But there are still many question marks. We don’t know to what extent the design study shown at NAMM corresponds to the final product. When the Wavestation was reborn as the Wavestate, Korg opted for a more compact design. Will the opsix also still be trimmed down to three or four octaves? But so far this is pure speculation – let’s be surprised!

If the rumours are true and the Korg opsix is really ready to roll out, we will of course keep you informed!

    I guess a pro keybed, music stand, and a metal casing was something that they only did in those old, regressive times.

    G says:

    Hope they change the front panel to black and get rid of the green LEDs on the sequencer, otherwise looks like a great synth.

    S R D says:

    A part of me still hopes for a full size keyboard, as per the name prototype and especially for the wave station, which would massively benefit from the extra keybed for splits, layers etc.

    But another part of me gets the design. Parts rationalisation (same or similar casing etc to keeps manufacturing costs down) plus a smaller footprint for travel /anywhere style gigging, recording and playing and you potentially have a winner on your hands out of the box.

    I just wish they’d offer the 61 key variants too for a bit more; it increases playability 100%

    Yet another FM synth that drags along algorithm concept from 1983. Why? When these days there is enough DSP power to have operators in a matrix like FM7/8 or Alesis Fusion and with that all possible feedbacks.

    mr grigg says:

    MODULE version for this and the Wavestate please….

    Broken Gadget says:

    Well done on picking up on this leak. It isn’t widely reported elsewhere. I wonder whether people are bound by non disclosure agreements and we can look forward to a slew of reviews and videos in the near future?

    antfactor says:

    And yes… NO HEADPHONE JACK ON FRONT… again(?!). Really, synth Manufacturers?? Have you ever had to plug in headphones on your machines. PLEASE fix this trend. Thank you.
