Korg Opsix - Operator Modes In Depth: FM Mode
Channel: Oscillator Sink
Date: 2021-05-01

Korg describe the opsix as an "Altered FM" synth, and although I understand from a marketing perspective why they're leaning into the FM side of things given the inspiration drawn from the legendary DX-7 (and the success of the Volca FM), I think "Altered FM" actually downplays the power within the opsix.

With the Opsix, Korg have taken some of the key philosophies form FM synthesis - in particular the idea of operators flowing into each other and altering the sound of each operator in a chain - but then asked the question: what if those operators didn't have to be doing FM? So, with that in mind: here's the first video in the series where I'll be doing a deep dive into the operator modes on the opsix, starting with the FM mode.
