The third of the Korg opsix firmware 2.0 effect operators that I’m covering in this series is the Comb filter effect operator. Related to the Short delay operator, the Comb filter is well suited to physical modelling of sounds.

One of the ten new effect operators in the Korg opsix 2.0 firmware is Short delay. This effect, while technically correctly named, has many more uses than its name suggests, including some in physical modelling.

In October 2021, Korg released a firmware update for its opsix synthesizer, introducing ten new operator types, a ragtag bundle grouped under the umbrella of “effects”. There isn’t much in common between the ten effects apart from the shared user interface used to configure them. This post is a deep dive into the Phaser effect.
