Filter design original by Rob Hordijk

This filter is using the Twinpeak principle of two inverse-parallel LP filters, and other instruments/modules that use this Twinpeak principle are in 24/7, Blipoo Box and 5 HU modules of Rob Hordijk, but with different LP-filter implementations and resulting sound. This filter produces incredible and new sound spectra. Vocal sounds, ping and ringing sounds and powerful low frequency bass sounds.

Use CV signal as input to get incredible ringing sounds. Tracking (Tr1 + Tr2) are direct linked to to input. Res mod modulates Resonance. This is the way to vocal sounds. This filter produces a very flexible and rapid changing bandpass with permanent changing bandwidth.
CV1+2 extra input for modulation. Joystick is central controller for Filter frequency of both filters.
