Unifilter

Self resonating filter. It does not sound very natural compared to real one. It does not introduces much un natural digital sounding effects into stuff. It sounds like broken tube amp.

Its definitely not for standard music, author think its for acid. I am not sure about acid.

Because it sounds like broken guitar tube amp from 60s, why not build on its strength and add cabinet simulator to it and because author is good in making distortion plugins add also some distortion stuff to it and it can become really interesting product. Do we have broken 60s amp simulator VST? we don't.
