Serge WVX FracRak Format
Serge WVX Euro-rack (Doepfer) Format
The WVX is based on the classic Wave Multiplier module designed by Serge Tcherepnin. Top and bottom sections of the unit are independent and transform an input wave in various ways. The effect is non-linear and useful on both audio and control voltage range wave forms, the most pronounced effect coming from low harmonic content waveforms like sine and triangle.
The top section has DC and AC coupled inputs that may be used alone or together. The signal from Out 1 of the top section adds odd overtones. Out 2 and 3 are from the Lockhart folder.
The bottom section is a full wave rectifier, transforming waves to positive voltage with even harmonics. Out 2 is a "squared" version of Out 1.
This module is divided into two sections, the top of the WVX correspond to the middle section of the classic Serge Wave Multiplier with additional outputs from a Lockhart wave folder. The Bottom section of the WVX corresponds to the bottom section of the Serge Wave Multiplier.
