How It Works
Technical view
The current freeze family does not capture and hold the live input. Instead, it mixes in a separately synthesized held phrase, runs that synthetic layer through one diffuser stage, and shapes it with a high shelf under `tone`. `motion` stretches the diffuser delay, `shape` raises the held layer level, and `mix` blends that fixed freeze pad against the dry phrase.

Signal Path
Compiled preview chain
Preview source: An internally generated picked-string phrase is widened to stereo as the dry source, and the current effect also layers a separately synthesized held or slowed phrase rather than capturing the live input into a loop buffer.

Preview source

Effect core
Dry phrase plus a separately synthesized held pad with one diffuser stage and high-shelf shaping.
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 held phrase
- diffuser stage on the synthetic pad
- high-shelf shaping on the synthetic pad
- dry / freeze 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 preview phrase and the synthesized freeze pad.
- output_gain_db: Applies final post-effect level trim after DC blocking and before the output limiter.
- motion: Lengthens the diffuser delay inside the synthesized freeze pad path.
- shape: Raises the gain of the synthesized freeze pad before it is mixed with the dry phrase.
- tone: Adjusts the high-shelf shaping on the synthesized freeze pad.

Controls
Audible controls in this DSP
Blends between the dry preview phrase and the synthesized freeze pad.
Lower settings stay more direct; higher settings push the held pad further forward.
Applies final post-effect level trim after DC blocking and before the output limiter.
Matches loudness without changing the actual loop, freeze, or glitch structure.
Lengthens the diffuser delay inside the synthesized freeze pad path.
Moves the held texture from tighter sustain toward a wider, more blurred pad.
Raises the gain of the synthesized freeze pad before it is mixed with the dry phrase.
Makes the held layer denser and more prominent.
Adjusts the high-shelf shaping on the synthesized freeze pad.
Makes the held layer darker at low settings and brighter at high settings.
Analysis
Code-derived notes
Current implementation shares the same synthetic hold-pad architecture across Granular Freeze, Momentary Freeze, and Sustain Pad. Sustain Pad currently uses the same synthetic hold core as Granular Freeze.
