How It Works
Technical view
The current `Resonator Reverb` uses the shared diffuse reverb core and adds a very short comb branch whose delay is set directly in samples, creating a resonant overtone on top of the ambience. `space` changes both the main reverb dimensions and the resonator period, `decay` extends both the tail and the resonant ring, and `tone` brightens both sections.

Effect core
Diffuse reverb core plus a short resonator comb branch mixed into the wet tail.
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
- added short resonator comb branch
- dry / wet blend
- 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: Blends between the dry source and the wet reverb field after the reverb core.
- output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
- space: Expands the base reverb dimensions and also increases the sample delay of the added short resonator comb.
- decay: Raises the feedback of both the base diffuse reverb and the added resonator comb.
- tone: Raises the damping cutoffs in both the base reverb core and the added resonator branch.
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
Blends between the dry source and the wet reverb field after the reverb core.
Lower settings stay more direct; higher settings move the patch further into the ambient tail.
Applies final post-effect level trim after DC blocking and before the output limiter.
Matches loudness without changing the actual reverb structure.
Expands the base reverb dimensions and also increases the sample delay of the added short resonator comb.
Moves the resonant overtone from tighter, higher ringing toward a looser, lower resonance.
Raises the feedback of both the base diffuse reverb and the added resonator comb.
Extends the ambience and lets the resonant ring persist longer.
Raises the damping cutoffs in both the base reverb core and the added resonator branch.
Makes the reverb and the resonant overtone darker at low settings and brighter at high settings.
Analysis
Code-derived notes
Current implementation adds a very short comb resonator on top of the shared diffuse reverb core rather than using a separate bank of tuned resonators.
