Official effect
Wide-range resonant low-pass sweep with a continuous LFO-driven center and darker post-filter tone.
This patch modulates a resonant low-pass center with a sine LFO whose depth is scaled by `motion`, while `focus` pushes the whole sweep upward and opens the post-filter high shelf. It is a straightforward moving low-pass voice without envelope following or stepped modulation.
Static peaks come from the compiled FAUST preview render. The live scope is drawn from the browser playback output in real time.

Signal Path
Preview source: An internally generated picked-string phrase is widened to stereo with a 19-sample right-channel delay and slight left/right shelf-EQ offsets before it hits the filter core.

Sine-LFO-modulated resonant low-pass filter with darker post-filter high-shelf shaping.
The static waveform and the live player both reflect this compiled signal chain.
These are the currently active controls detected in the FAUST source for this effect.
The generated description is tied to the active helper blocks and routing found in the current DSP.
Controls
Blends the untouched stereo preview source with the filtered path after the effect core.
Lower settings preserve more dry attack and full-band tone; higher settings emphasize the filter treatment.
Applies final post-effect level trim after DC blocking and before the output limiter.
Matches loudness without changing the filter behavior itself.
Sets the base center of the resonant low-pass sweep and the amount of post-filter high-shelf recovery.
Moves the sweep higher and opens the output brighter as it rises.
Increases sweep depth and resonance of the low-pass filter.
Makes the sweep wider and more resonant.
Sets the speed of the internal LFO that moves the low-pass center.
Changes how quickly the filter sweeps through its range.
Analysis
Current implementation shares the same resonant low-pass sweep core as Pick-Sensitive Low-Pass, despite the different name.
No current warnings are attached to this effect.
