Eternal is a barber-pole flanger. Unlike a traditional flanger which has its tone repeatedly go up and down, a barber-pole flanger goes upwards or downwards in a seemingly endless fashion. To accomplish this unique effect, Eternal employs a thoroughly calibrated low-frequency oscillator with six output signals which modulate and crossfade three flangers – and they do this in a very special way. Since these oscillators have a “through-zero phase” design, Eternal can go from downwards to upwards motion and back completely seamlessly.
This plugin is part of the Sinveibes KorgFX Collection.

Before You Start ⚠️
In order for the effect plugins to function correctly, you must make sure that your Korg synthesizer has the latest available firmware update and that after installing it you also perform the panel update and voice update procedures.
If you install the firmware update but do not complete the panel and the voice updates, this can negatively affect other aspects of your instrument’s operation, not just compatibility with third-party plugins. When you power your synthesizer on, the main screen will warn you if such additional updates are required. Please refer to your Korg product's user manual for how to check the firmware version installed on your synthesizer - and visit www.korg.com to download the latest version. The download package will also contain the instructions for doing the panel and voice updates.
