01Overview

Fix Flanger and Doubler is built around a flanger and a doubler effect. Softube presents it as a reimagining of a Paul Wolff design first formalized in 1979, updated for digital production. The Fix Flanger covers guitar-pedal-style automatic sweeps as well as manual, hands-on control. The Fix Doubler uses a streamlined interface and an Auto Double algorithm to create smooth doubling and lush chorus on vocal tracks.

03In depth

Flanging with Hands-On Control

The Fix Flanger works in two ways. Its automatic mode produces a swept flange in the style of a guitar pedal, and its manual mode lets you shape the effect directly.

A VSO mode is the feature Softube highlights most. It emulates servo motor bounce and offers true cross-zero flanging, which the developer compares to the behavior of a tape machine. Tap tempo sweep, several stereo widening methods and selectable delay polarity give you more ways to shape the sweep and the stereo image.

Vocal Doubling and Chorus

The Fix Doubler is aimed at vocals and polyphonic instruments. It adds texture and richness, and it draws on the same algorithms as the Fix Flanger inside a simpler interface.

The Auto Double mode is designed for natural-sounding doubles. Softube says it uses phase cancellation to create the effect and can produce smooth doubling without flanging at delays as low as 3 ms.
