VIBE is a four-stage phase shifter voiced after optical modulation: the sweep breathes instead of marching, so slow settings feel like movement in the room rather than a machine cycling. RATE runs from a 20-second drift to a 10 Hz shimmer; DEPTH sets how far the sweep travels through the stages; FDBK feeds the chain back into itself and deepens the notches from a gentle wash to a hollow, vocal resonance.

The main output blends dry and shifted signal with MIX. The VIB output carries the raw allpass sum before the mix — patch it on its own for vibrato-style pitch wobble, feed it to a second input for stereo movement, or process it further and blend it back.

Controls and patching

• RATE — 0.05 to 10 Hz, exponential, CV input.
• DEPTH — sweep depth through the four stages, CV input.
• FDBK — feedback around the stage chain for deeper notches, CV input.
• MIX — dry/wet blend on the main output, CV input.
• OUT — the blended output.
• VIB — the raw shifted signal, before the mix.
