Filters
A low-pass filter emulating a 4-pole transistor ladder.
It attenuate around 24dB/octave.
It tries to recreate the classic warm sound of the original analog transistor filter.
CUTOFF
With the cutoff attenuator turned fully clockwise the cutoff CV input will modulate with 1V/octave.
DRIVE
The drive control the input gain. Lower gain will make the filter give a more linear response, it can also increase the ratio of resonant peak versus passband gain. At higher gains the non-linear response of the filter can start to distort the passband also, which can lead to some compelling sounds.
RESONANCE
When input is unplugged or go silent at very high resonance setting it can self-oscillate, if resonance is dialed too low again, it will stop and the procedure have to be repeated to get it going again.
