Klavis Grainity

Digitally-controlled full-analog path Granular + Multimode VCF

The Grainity brings a unique and never-heard-before concept to the world of analog VCF.
While being based on analog filtering only, the Grainity expands and enriches the sound in creating subharmonics, harmonies, unison, flanging effects and formant filtering all at once.

The module presents two sections, the granular filter itself and a typical multimode filter, each with its own output.
A third output offers a mix of both filter paths. Numerous controls and CV allow a very wide palette of results.
