The 24dB VCF SSI is a voltage controlled analog low pass filter module in Eurorack format. The module has a cascade filter with SSL2144 chip and an additional 12dB output, which works either as low pass or bandpass (+/-12dB). The module has two inputs, one of which has an attenuator. Further attenuators are at the CV input and at the CV input for the cutoff frequency. The resonance can be controlled either by a knob or by another CV input with attenuator.
