Orchid: Four-Way Chorus Plugin by W. A. Production Free Download

Most chorus plugins double the signal. Orchid quadruples it, and the developer notes that some of its changes are applied separately to each of the four chorus modules. This pushes the sound toward phasing and comb-filtered textures.

The Speed, Depth, Feedback and Spread controls shape the effect. Feedback sets how much of the signal returns to the input, changing the intensity of the effect, while Spread moves the sound across the stereo field.

The Shimmer dial adds up to two octaves above the original audio with a slow phasing effect, which brightens the top end. The Space dial adds reverb to each chorus module to glue them together.

The Delay control offsets the processed signal by up to 100 milliseconds, which helps separate it from the original audio. High and low pass filters shape the processed sound, for example to keep only low-end weight or only top-end sheen.

The central Mix control sets the balance between dry and chorus signal for parallel processing. The bypass is smoothed to avoid clicks and pops, and the Input and Output sliders support A/B comparison. A live meter in the centre of the interface shows the signal as it moves through each module.
