Horripilation

Distortion/Signal Processor

horripilation is an audio processor module for eurorack used for oscillating distortion effects.
the first stage is a 6cb6 pentode amplifier with feedback.
cv for feedback with a vactrol for unique slewed slappy blippy response.
then the output of that first distortion processor is fed into a smooth non resonant filter/tone shaper created with another 6cb6 pentode and also using a vactrol for cv.

with the filter knob full clockwise it lets through all the oscillating feedback sounds.
pulling back counter clockwise rolls off some of the harshness.
the intended use is to get plucky rhythms by inserting pulses or snappy envelopes into the cv of the filter.

try using this module in patches where you would normally use a low pass gate but then follow it up with a vca(like the right channel of the tvm23) to fully close off the signal.

this module is best used for processing the output of a vco.
high frequency fm'd sources work best.
