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 transistor based 3-channel mixer and an LFO with Triangle, Square and inverted Triangle outs, that are normalled to CUTOFF and Q. This connection is interrupted as soon as external CV is plugged into the corresponding CV inputs. The small trimmer potentiometers CV/FREQ and - FM + will attenuate the amount of the LFO voltage affecting the filter frequency. - FM + is an attenuverter (positive and negative). If you want to switch off the LFO, set - FM + to mid position and CV/FREQ fully counter clockwise. CV/Q will set the amount of CV affecting the resonance. 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. Released under cc-by-sa-3.0 license.
