10HP Modification of Émilie Gillet´s „Ripples“ Filter
Actually its a Franz´d Ripples, if you like. Just like Franz, Werner is a filter with an internal mixer and LFO. It is not as
buttery as Franz, but still one of the best filters around.
It has all the functionality of the original Ripples module, but also provides a 3-channel MOOG CP3 transistor based
mixer and an LFO with Triangle, Square and inverted Triangle outs, that are normalized to CUTOFF and Q. These
connections are interrupted as soon as external CV is plugged into the corresponding CV inputs.
The small trimmer potentiometers CV/FREQ and CV/FM will attenuate the amount of the LFO voltage affecting the filter
frequency. CV/FM is a bipolar attenuverter (positive and negative). CV/Q will set the amount of CV affecting the
resonance. If you want to switch off the LFO, set CV/FM to mid position (12 o´clock) and CV/FREQ and CV/Q fully counter
clockwise. Connections: LFO Triangle Wave --> CV/FREQ, LFO Square Wave --> CV/FM, LFO Inverted Triangle Wave --> CV/Q
There is also an LFO RESET input in order to restart the LFO cycle. This way you can synchronize the CUTOFF movements
to a rhythmical pattern.
