Korg opsix Altered FM Synthesizer

   (0 reviews)

The opsix is a 24 - 32 voice Digital Altered FM synthesizer by Korg. It was shown as a non-functioning concept model at NAMM 2020 with a 5 octave keyboard however the release model is the same form factor as Korg's Wavestate with 37 keys and a lightweight build.

Opsix uses the traditional algorithmic 6 operator Frequency Modulation synthesis found on many of the Yamaha DX series keyboards, but Korg has 'Altered' it by adding real-time controls for many parameters and modern features such as:

3 LFOs and 23 waveforms including unipolar options

3 ADSR envelopes with curve control

11 type multimode filter with FM and key tracking

21 oscillator waveforms including additive waves and noise

30 onboard effects with 3 available in series

32 voice max polyphony

40 algorithms plus user designed option

Ring modulation between carriers and modulators

Wave folding of the oscillator and modulator

Virtual patch function for modular synthesis-type routing

Polyphonic step sequencer and 6 lane Motion Sequencing

Initial and release velocity sensitive keybed

Spectrum analyzer and oscilloscope

DX7 Sysex compatibility

Korg has also provided software for your computer or mobile device from other manufacturers with the opsix including Izotope's Ozone Elements, Skoove and Reason Lite.
