Pole-Zero MOSFET VCF & VCA

WMD / SSF Pole-Zero

The Steady State Fate and WMD Pole-Zero is a MOSFET VCF with an internal VCA. The module features a 4-pole low-pass filter with voltage-controlled amplitude modulation.

The MOSFET drive allows for the creation of chunky waveshapes and deep bass tones. Since the filter is capable of self-oscillation it can function as a sine wave VCO with 1V/Oct tracking. There’s also a dedicated FM input with a reversing attenuator—all in a compact 6HP!
