STG Soundlabs Mankato Filter Review

The Mankato Filter is a four-pole lowpass filter, designed by Thomas Henry. It offers positive and negative outputs at every pole, giving you slopes of 6 dB/oct, 12 dB/oct, 18 dB/oct, and 24 dB/oct simultaneously. And the negative slope outputs let you use the Mankato as a quadrature sine oscillator, with 8 available phases.
