Hi-Hat

What it does

808-style metallic hi-hat voice.

Wraps daisysp::HiHat<> (square-noise metallic source). A file-scope prev_trig snapshot detects rising edges — each Trig press fires once. Decay sets the open/closed character.

Parameters

• Freq (Hz)

  freq
  Default 3000Range 500 … 8000

  Root frequency of the metallic tone in Hz — six detuned square oscillators are built from it. 3 kHz is DaisySP's own default and sits where a real hat lives.

• Decay

  decay
  Default 0.4Range 0 … 1

  Length of the hit, and the one control that decides closed vs open: short reads as a closed hat, long as an open one. Wire it to a knob or pad to switch between them live.

• Tone

  tone
  Default 0.5Range 0 … 1

  Overall brightness. It moves the filtering around the metallic noise, from dark and washy at 0 to sharp and glassy at 1.

• Noisiness

  noisiness
  Default 0.8Range 0 … 1

  Balance between the tuned metallic ring and pure noise: 1 is all noise, 0 is all tone. The 0.8 default leans noisy, which is what makes it read as a hat rather than a bell.

• Accent

  accent
  Default 0.5Range 0 … 1

  Hit intensity — how hard the stick lands. It raises level and brightness together rather than acting as a plain volume.

• Infinite Sustain

  sustain
  Default false

  Makes the hat ring out forever instead of decaying, turning it into a continuous metallic noise source you can filter or gate elsewhere.
