Polyphemus II uses a single real pole to create a voltage-controlled lowpass filter with v/oct tracking and envelope inputs for use as a lowpass gate. There are 4 total filters provided with 3 channels each. They can be cascaded, though this alters the cutoff frequency of the resulting filter. In the future each of the 4 filters should include an order control to increase the pole-order while still tracking v/oct.
