Description
NorthPole is a resonant filter by Prosoniq that combines 24 dB-per-octave lowpass and bandpass filtering with distortion and a post-filter digital delay. Variable cutoff and resonance define the core tone, while an envelope follower can drive the filter from the incoming signal.
Adjustable envelope attack and release, distortion amount, and delay time, mix, and feedback make it useful for both animated filtering and colored echoes. VST, AU, and RTAS versions are listed for Windows, macOS, and Mac OS 9.
