Lupex Chorus is an analog BBD-style stereo chorus VST3 plugin by Fauz Audio, built with JUCE and CMake.
Inspired by the character of classic analog chorus pedals like the MXR M234 Analog Chorus.
- Dual BBD-style analog chorus chains — true stereo with independent L/R processing
- Quadrature LFO modulation (90° phase offset) for wide stereo image
- Low and High shelf tone controls based on MXR M234 specifications
- MXR-style stereo routing — dry + wet on L, wet-only on R for natural depth
- Rate smoothing for organic pitch glide when changing speed in real time
- Bypass footswitch with LED indicator
