Igorski Released Rechoir, a freeware delay effect in VST2 and VST3 plugin formats for Windows and macOS (AU support expected soon).
Delays are one variety of effects that open themselves up to endless possibilities. Developer Igorki’s Rechoir is one such take on a novel delay.
Rechoir certainly operates as a host syncable delay, but where it differs from its peers is in its ability to alter the pitch and add harmonies to the taps it produces.
The interface is utilitarian, presenting all controls with clear labeling. The first section is for control of the delay itself, with controls for syncing to the host’s tempo or operating off timing alone. Also present in the delay’s controls are a freeze function, which was fairly easy to coax some unruly noise out with when running the feedback at higher levels.
As the star of the show, the pitch section has some interesting controls which are thankfully easy to grips with. The shift knob dials in the percentage of pitch shifting being applied to the taps. Scale is also present and acts as a quantizer for the pitch-shifted taps to fit into scales with the labels neutral, happy, sad, dark, and evil.
In practice, these are just the modes with neutral acting as the Major scale, happy as Mixolydian, and so forth.

Rechoir is an interesting feature, allowing producers to harmonize the taps as a means of modulating the taps. These act as independent delay lines, which are also synced to the host. They seem to add complimentary timbres to your specified scale and have a rather unusual quality about them.
Decimator is a typical bitcrusher, which sounds perfectly fine when applied to the taps. The artifacts present add character and grit at lower percentages, and can quickly make the delay sound like it’s being crunched through a 1-bit register when pushed to maximum percentages.
Rechoir isn’t a delay for all seasons, but it is a splendid creative effect that can add some additional textures when coupled with your favorite heavily diffuse reverb.
Windows and macOS are supported, and installation is a simple copy/paste to your plugin folder of choice. Windows host support is 64-bit only, with VST2 and VST3 formats provided. Mac users don’t have explicit Silicon M1 support. Apple users only have access to VST2 and VST3 as well, with no indication of a forthcoming AU.
