From the developer:
Noisebud filter consists of four filters (or 16, depends on how you look upon it) and they are switchable between Lo pass, hi pass, band pass and band reject filter.
The signals from the four filters are wired in a parallel chain. Every filter can be controlled by three different LFO’s where one is tempo synced; one normal and one extremely slow (a sLoFO). The LFO sections also have something called VariFO.
