WERNER10HP 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. Released under cc-by-sa-3.0 license.

Details:

• Analog Filter • 3 Filter Outputs: Low Pass 2-Pole, Low-Pass 4-Pole, Band Pass 2-Pole • VCA for Low-Pass 4-Pole • Internal LFO with three Waveforms: Triangle, Inverted Triangle & Square • LFO Reset, LED indicating LFO rate, LFO normalized to Filter Circuit • Apply three LFO waveforms at the same time • Attenuator for each LFO Wave or external CV • 3-Channel MOOG CP3 transistor based Mixer • Volume control for each Mixer Channel • Wrong Polarity Protection • 3U Eurorack module, 10 HP wide • Power consumption: 55 mA at +12 V and 55 mA at -12 V
