How It Works
Technical view
The current synth-family wet path does not follow the dry source. It mixes in a separately triggered multi-oscillator phrase built from a sine fundamental, harmonic partials, and a lightly modulated upper oscillator, then crossfades that phrase with the dry stereo preview source through `mix` and `blend`. In the current implementation the top-level `color` and `motion` sliders are not wired into the wet path; the synth notes use fixed per-note tone values instead. The result then passes through the shared DC-blocking, output-gain, and soft-limiting stage.

Signal Path
Compiled preview chain
Preview source: An internally generated picked-string phrase is widened to stereo with a 19-sample right-channel delay. The wet side is a separately synthesized phrase triggered on fixed note events rather than being derived from the dry input.

Effect core
Current shared multi-oscillator synth phrase crossfaded against the dry preview phrase.
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
- separately synthesized multi-oscillator phrase
- fixed per-note synth tone shaping
- dry / synth crossfade
- 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: Crossfades the dry stereo preview source toward the current wet layer.
- output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
- color: Declared in the shared control set but unused in the current preview code.
- motion: Declared in the shared control set but unused in the current preview code.
- blend: Scales the level of the synthetic phrase inside the wet path before it is crossfaded with the dry source.

Controls
Audible controls in this DSP
Crossfades the dry stereo preview source toward the current wet layer.
Higher settings put more of the synthesized or resonant effect layer in front of the dry phrase.
Applies final post-effect level trim after DC blocking and before the output limiter.
Matches loudness without changing the underlying effect structure.
Declared in the shared control set but unused in the current preview code.
Changing it currently has no effect on the sound.
Declared in the shared control set but unused in the current preview code.
Changing it currently has no effect on the sound.
Scales the level of the synthetic phrase inside the wet path before it is crossfaded with the dry source.
Higher settings make the synth layer denser and more dominant.
Analysis
Code-derived notes
Current implementation shares the exact same synth architecture with Mono Synth Lead, Square Synth, Fuzz Synth, Sub Synth, String Machine, Choir Pad, and Spectral Smear. There is no progressive harmonic-bloom envelope stage yet, and the top-level color and motion sliders are not wired into the wet path.
