Frequently Asked Questions
The CV input modulates the phase shift of each output stage, creating dynamic and evolving textures. The range of modulation is determined by the control knob’s position.
Absolutely! While designed for VCO signals, it works well with other waveforms, adding interesting phase-related harmonics and complexity.
Like many analog modules, it can exhibit aliasing artifacts at higher frequencies, especially with complex waveforms, so careful signal management is important.
