Classic Steiner Parker Diode Filter

This versatile filter is back. Because this is a diode filter it is
inherently noisy but the Rev2 has gone a long way in quieting things
down. In addition the resonance has been slightly tamed. While it is
still able to go completely out of control, this only happens at the
very end of the Resonance pot sweep. The DiOD is a very flexible filter,
it can go from subtle and smooth to rough and brutal while having a
skiff's friendly design and only taking 4HP of your case.


This filter will track, but not as tight as the VCOb and it will self-resonate; in fact at the upper reaches of the Resonance it's pretty hard to control.



The 2 CV inputs can be CV or Audio.
