WMDPDO MKII Phase Displacement OSC


In Stock Available immediately!


The WMD PDO mkII combines the warm sound of an all-analog VCO with the advantages of digital waveshaping. The module itself is a redesign of WMD’s Phase Displacement Oscillator, albeit with a more ergonomic front panel, less power consumption, and upgraded phase input routing.

The aim of the PDO mkII is phase modulation, which affects the relative phase of the generated waveform rather than the frequency, making it adept at creating metallic tones and controlled harmonic interplay. The module can also be used as a PM-centric VCO, making it incredibly useful for the precise modulation of other modules. If that’s not enough, each of the module’s outputs can output any of the available waveforms at the same time!
