Primitive Coastal Electronics — Fight Song Revisited

Because The First Filter Didn't Work

An OTA state-variable VCF configured to add a little bit of hair to otherwise harmonically anemic input signals. A 2-channel input mixer is made available with one input mixing at unity and a second at 2x gain. Following the mix sum is a variable (but never full “off”) asymmetric saturation stage. With nothing plugged into the cutoff cv input, the input sum is normalled to the jack, and the attenuator acts as a cross-modulation control. LP, BP, and AP outputs are available simultaneously for feedback patching experimentation.
