Additive Bell

Currently the same FM-like bell phrase as FM Clang rather than a fuller additive partial bank.

The current bell-family wet path mixes in a separately triggered metallic phrase built from one FM-like oscillator stack plus a fixed high partial, then crossfades that bell layer 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 bell 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 metallic phrase rather than a live struck-resonator analysis path.

Preview source

Effect core

Current metallic bell phrase shared with FM Clang, 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 metallic bell phrase
  • fixed per-note bell tone shaping
  • dry / bell 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 metallic bell phrase inside the wet path before it is crossfaded with the dry source.

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

  • mix

    Active

    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.

  • output_gain_db

    Active

    Applies final post-effect level trim after DC blocking and before the output limiter.

    Matches loudness without changing the underlying effect structure.

  • color

    Active

    Declared in the shared control set but unused in the current preview code.

    Changing it currently has no effect on the sound.

  • motion

    Active

    Declared in the shared control set but unused in the current preview code.

    Changing it currently has no effect on the sound.

  • blend

    Active

    Scales the level of the metallic bell phrase inside the wet path before it is crossfaded with the dry source.

    Higher settings make the clang-like layer more forward.

Analysis

Code-derived notes

Current implementation shares the exact same metallic bell architecture with FM Clang. It is not a broader additive partial bank yet, and the top-level color and motion sliders are not wired into the wet path.
