"12 dB State Variable design
Voltage control of frequency and Q
Two position Q switch: "Filthy: X10, X100"
+/- CV mod attenuator with switchable destination: Freq or Q
VC mode select: switch or morph (LP, BP, HP, All Pass)!
Plus separate mode outs: LP, BP, HP, Notch
This is a 12dB/octave response voltage controlled filter. The design is based on the classic State Variable configuration that provides simultaneous low pass, band pass and high pass outputs. In addition, the Filthy Filtre has notch and all pass (phase shift) outputs.Voltage controlled Q is also provided with a special dual range feedback circuit that gives maximum total crunchy mind warping self oscillation. Beware your ear drums, amps and tweeters at high levels! An additional modulation input, routable to either frequency or Q through a bipolar attenuator, is a handy feature.The mode or filter type is also voltage controllable, allowing switching or morphing between low pass, band pass, high pass and all pass filter types. Separate audio outs for most filter types are also found at the module bottom.
Note : as this is a Frac module it is not power-compatible with eurorack systems (ie this needs +- 15V)
if you have a frac system however it is patch compatible with a eurorack system"
