Supercritical Synthesizers Neutron Flux 8 Pole Variable Character Filter

Supercritical Synthesizers shared this video demo of their new Neutron Flux 8 Pole Variable Character Filter, an 12hp skiff-friendly module, featuring a stereo analog core and extensive digital control.

According to the company, digital control lets the core take on the character of almost any classic filter, and gives the filter the ability to explore sounds that have never been heard before.

Here’s what they have to say about it:

“The module can be used in many different ways. It can do classic LP/HP/BP filtering. It can self-oscillate with different waveforms. It can provide analog warmth and it can process audio from your DAW. It can act as a stereo distortion. It can spread your mono signal to a wide spatial stereo soundscape. It can do formants and other wild characters. It can do audio-rate deep FM (1V/oct and FM CV’s are all analog). It can behave nicely or get out of control.”

The controls are familiar filter module controls (cutoff, bipolar FM, mode, drive) with some ‘added spice’:

  • Character: This control blends between five vintage influenced classic filter characters: Fat, Crisp, Liquid, Sour and Mean. Coming later in a firmware update, the Neutron Flux will also have two user banks for more specialized filter characters which can be replaced via audio update.
  • Overdrive: You can switch on the drive circuit for a +20dB boost and have the drive pot sweep from clean via warm saturation to extremely hard distortion.
  • Stereo: This control spreads the cutoff between L and R channels and induces drift. This way a mono signal can be split into wide stereo.
  • Two 4 pole filter cores: These can be run in stereo, mono to stereo or chained as a 8 pole mono filter for almost LPG-like steep slope. Both of them have their own drive circuits so you can have the overdrive stage in the front, in between or both.
