Drone Generator

Adds a sustained low organ tone beneath the main synth phrase for a held pedal-drone layer.

The current drone wet path layers the shared self-triggered synth phrase with a held low organ note, then shapes the combined layer with a `color`-driven low shelf and a `motion`-driven high shelf before crossfading it with the dry stereo preview source through `mix`. `blend` both raises the organ drone contribution and scales the overall wet layer. 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 adds a separately synthesized phrase plus one sustained low organ drone rather than generating a free-running drone from live input.

Effect core

Self-triggered synth phrase plus sustained low organ drone, 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 lead phrase plus held low organ drone
  • color-controlled low-shelf reinforcement
  • motion-controlled high-shelf shaping
  • dry / drone 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: Raises the brightness of the held organ drone and the low-shelf reinforcement applied to the combined wet layer.
  • motion: Sets the high-shelf gain on the combined wet layer.
  • blend: Raises the held organ-drone gain and also scales the overall wet-layer contribution in the final crossfade.

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

    Raises the brightness of the held organ drone and the low-shelf reinforcement applied to the combined wet layer.

    Higher settings make the drone thicker and more present in the low mids.

  • motion

    Active

    Sets the high-shelf gain on the combined wet layer.

    Opens the top end of the drone layer as it increases.

  • blend

    Active

    Raises the held organ-drone gain and also scales the overall wet-layer contribution in the final crossfade.

    Higher settings make the sustained drone heavier and more dominant.

Analysis

Code-derived notes

Current implementation layers the shared synth phrase with one held low organ voice and shelf EQ. It is not a free-running drone engine or live input follower yet.
