Silica is just my crack at making a granular pitch shifter from scratch using multiple lfos and the delay modules. Dual signal paths run saw LFOs slowing/speeding up grains and fade smoothly between the two paths to avoid the saw wave reset popping noise. There are multiple unison paths to smooth the sound out as well as a spectral smoothing option that slightly moves the multiple grains phases and then a diy treble exciter to make it less muddy. I’d like to have an option to tame some of tremolo effect caused by the fades but some people may find it interesting
