How It Works
Technical view
The current shimmer-style family does not pitch-shift the live reverb tail. Instead, it blends the shared diffuse reverb core with a separately synthesized bright picked phrase that is mixed into the wet field. `space` and `decay` only reshape the underlying reverb core, while `tone` brightens that core beneath the fixed-bright auxiliary shimmer layer.

Signal Path
Compiled preview chain
Preview source: An internally generated picked-string phrase is widened to stereo as the dry source, and the shimmer-style patches also layer a separately synthesized bright picked phrase into the wet field instead of pitch-shifting the live reverb tail.

Effect core
Diffuse comb-and-diffuser reverb plus a separately synthesized shimmer phrase blended into the wet field.
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
- four parallel damped comb stages
- two serial diffuser stages
- post-reverb high-shelf shaping
- separately synthesized shimmer phrase
- dry / wet blend with auxiliary shimmer layer
- 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 both the diffuse reverb field and the separately synthesized shimmer layer against the dry source.
- output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
- space: Expands the comb-and-diffuser lengths of the underlying diffuse reverb core.
- decay: Raises the feedback coefficients of the underlying diffuse reverb core.
- tone: Brightens the underlying diffuse reverb core; the auxiliary shimmer phrase itself stays fixed-bright in the current code.
Code-backed analysis
The generated description is tied to the active helper blocks and routing found in the current DSP.

Controls
Audible controls in this DSP
Scales both the diffuse reverb field and the separately synthesized shimmer layer against the dry source.
Lower settings keep the direct phrase forward; higher settings bring up both the reverb bloom and the added harmonic lift.
Applies final post-effect level trim after DC blocking and before the output limiter.
Matches loudness without changing the actual reverb structure.
Expands the comb-and-diffuser lengths of the underlying diffuse reverb core.
Moves the ambience from a closer halo toward a larger floating wash.
Raises the feedback coefficients of the underlying diffuse reverb core.
Extends the reverb tail beneath the added harmonic layer.
Brightens the underlying diffuse reverb core; the auxiliary shimmer phrase itself stays fixed-bright in the current code.
Changes how dark or open the supporting reverb tail feels under the added shimmer voice.
Analysis
Code-derived notes
Current implementation shares the same diffuse-reverb-plus-synthesized-shimmer architecture across Shimmer, Harmonic Reverb, and Chorale Reverb. Harmonic Reverb is not yet differentiated from Shimmer.
