Laurentide SynthWorks has announced the Baal 3080 4-Pole VCF, for MU modular synthesizer systems.
At its core of the module is the filter that was in the original RevA version of the Octave Cat, before they switched to the SSM2040. The filter design has been adjusted for modular level and the expo-converter uses super-matched 3906’s and temperature compensated for upwards of 5-octave tracking.
Additionally, there is a 4-pole output as well as a 1-pole output. These outputs are inverted from each other, so they can be mixed together for Bandpass.
Here’s a video demo, via synthesist John L Rice:
