WMD Protostar Envelope Filter - MeMe Antenna

WMD Protostar Envelope Filter


  • $349.00

The Protostar is the evolution of the Super FatMan envelope filter with even more pro level features. Built in LFO, 4 filter modes, full CV patch bay, and expression/CB input, this is the most powerful/versatile envelope filter on the planet. Also includes an end of chain compressor and dry wet mix for parallel filtering/compression effects!

The architecture of this filter is similar to the Super Fatman, but with the addition of two and four pole filters and a notch (resonance down for phase like effects). Distortion and noise are lower, headroom is way higher, but the envelope gives the same natural expressiveness.
