Hold Delay

Damped comb-style repeat hold that can sustain a looped tail without a separate capture buffer.

The current `Hold Delay` patch is a damped comb loop whose delay length is set by `time`, whose recirculation is set by `feedback`, and whose brightness is controlled by the low-pass damping cutoff under `tone`. It blends that sustained loop against the dry source, so the result behaves more like a stable resonant hold than a discrete record-and-freeze buffer.

How It Works

Technical view

The current `Hold Delay` patch is a damped comb loop whose delay length is set by `time`, whose recirculation is set by `feedback`, and whose brightness is controlled by the low-pass damping cutoff under `tone`. It blends that sustained loop against the dry source, so the result behaves more like a stable resonant hold than a discrete record-and-freeze buffer.

Effect core

Damped comb-loop hold texture blended against the dry source.

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
  • damped comb feedback loop
  • dry / processed 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 processed delay texture after the effect core.
  • output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
  • time: Sets the delay length of the damped comb loop.
  • feedback: Raises the recirculation coefficient of the comb loop.
  • tone: Raises the low-pass damping cutoff inside the loop.

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

    Blends between the dry source and the processed delay texture after the effect core.

    Lower settings stay more direct; higher settings move the patch toward the effected repeat field.

  • output_gain_db

    Active

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

    Matches loudness without changing the actual delay structure.

  • time

    Active

    Sets the delay length of the damped comb loop.

    Moves the held texture from tighter resonance to longer looping space.

  • feedback

    Active

    Raises the recirculation coefficient of the comb loop.

    Makes the held tail sustain longer and build more intensity.

  • tone

    Active

    Raises the low-pass damping cutoff inside the loop.

    Makes the held repeats darker or brighter.

Analysis

Code-derived notes

Current implementation is a damped comb hold rather than a discrete capture-and-freeze buffer.
