How It Works
Technical view
The current `Looper` path does not record or overdub audio into a loop buffer. Instead, it adds one delay tap per channel over the dry phrase, with `motion` setting the tap lengths and `shape` raising their gain. The declared `tone` control is inactive, so the patch behaves as a simple stereo repeat rather than a true looper.

Preview source
An internally generated picked-string phrase is widened to stereo with a 19-sample right-channel delay before it hits the current looper or glitch core.
Effect core
Dry phrase plus two simple stereo delay taps with adjustable timing and tap gain.
Signal path
The static waveform and the live player both reflect this compiled signal chain.
- internal picked-string demo phrase
- stereo spread with a short right-channel delay
- independent left and right delay taps
- tap gain shaping
- delayed taps added over the dry phrase
- DC blocker
- output gain trim
- final tanh limiter
Controls that matter
These are the currently active controls detected in the FAUST source for this effect.
- mix: Scales the added delayed taps over the always-present dry phrase.
- output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
- motion: Sets the lengths of the left and right delay taps that stand in for the loop repeat.
- shape: Raises the gain applied to the delayed taps.
- tone: Declared in the shared control set but unused in the current preview code.

Controls
Audible controls in this DSP
Scales the added delayed taps over the always-present dry phrase.
Higher settings make the delayed repeats more audible without removing the direct attack.
Applies final post-effect level trim after DC blocking and before the output limiter.
Matches loudness without changing the actual loop, freeze, or glitch structure.
Sets the lengths of the left and right delay taps that stand in for the loop repeat.
Moves the repeated phrase from tighter slap-like timing toward a longer loop-like gap.
Raises the gain applied to the delayed taps.
Makes the repeat more prominent and louder relative to the dry phrase.
Declared in the shared control set but unused in the current preview code.
Changing it currently has no effect on the sound.
Analysis
Code-derived notes
Current implementation is a simple stereo repeat rather than a real loop recorder or overdub engine, and the declared tone control is inactive.
