rainbow

Rainbow is a wavetable FIR convolution effect for the Expert Sleepers Disting NT. It transforms audio by using wavetable waves as filter kernels, allowing you to colour audio through different filtering characters. Sine waves produce smooth filtering, complex waveforms create resonant effects, and morphing between waves yields evolving timbral shifts.

Supports 1-12 channels with per-channel wavetable position offset via a Spread parameter for stereo width or multichannel variation. Key controls include wavetable selection, Index positioning, Depth (wet/dry), Resolution (64-512 tap kernels), Gain, and Saturation.
