Flare additive synthesis oscillator


Flare is an additive synthesis oscillator plugin for KORG prologue, minilogue xd and NTS-1. It runs 8 sine wave partials configured as a harmonic series that can be further shaped by one of many different pitch ratio curves, which allows the plugin to produce a wide range of timbres: from smooth and organic to atonal and metallic. The "spectrum trim” feature makes it possible to gradually reduce the amount of additive harmonics, essentially acting like an ideal brick-wall low-pass filter – plus, it’s always working progressively towards the higher frequency range, resulting in a perfectly clean output with absolutely zero aliasing. Flare also features a built-in multi-mode modulation generator which can be applied onto three parameters at the same time, adding dynamic sound animation.
