The nasty way to sculpt and refine your sounds

Do you know how Jimi Hendrix got his signature guitar sound?
Nonlinear Filter.

Or that screechy lead in Block Rockin' Beats, by The Chemical Brothers?
Nonlinear Filter.

How about the synth melody in Madonna's Like a Virgin?
Believe it or not, Nonlinear Filter.

Alright, maybe not OUR Nonlinear Filter. But if you are looking to add some vintage analog twang to your sound, we have you covered. Nonlinear Filter offers basic filtering with a variety of flavors to it, ranging from classic analog sounding filtering to more outlandish modes the further down the list you go.



Select between low pass, band pass, high pass and notch filters.


The operating frequency of the filter.


The filter Q setting. High values for Q will make the filter resonate at the cutoff frequency.


Overdrives the filter, which makes the effect of the nonlinear behaviour more prominent.


Selects what flavor of nonlinearity you want. The clean mode has no nonlinearies, and does not color the signal. All other modes distort and color the signal in different ways to some extent.

Snapins are regular effects plugins (VST/AAX/AU) that also work as effects units in our modular Snapin Hosts; Phase Plant, Multipass, and Snap Heap, allowing you to create your own unique effects combinations. They are lightweight and powerful plugins that present you with the important settings in a no-nonsense way, so you will be using them like a master in no time.
