What it does
- Stereo flanger with an emulated bucket-brigade delay response.
- Three combinable modulation sources: auto LFO, envelope and manual.
- Additions to the original: zero-crossing effect, stereo offset, reverse sweep and a 12 dB per octave input high-pass.
- Function generator from Pigments can override manual modulation; LFO rates sync to tempo.
- Mono and stereo modes, with 28 presets.
