Modal Voice

What it does

Mallet-excited modal resonator voice.

Wraps daisysp::ModalVoice (click → LPF → resonator). A file-scope prev_trig snapshot detects rising edges; each edge is passed into Process(bool trigger) to strike the body. Accent + Sustain are baked at init.

Parameters

• Structure

  structure
  Default 0.25Range 0 … 1

  Changes the character of the resonating body by altering how its modes are spaced, effectively how stiff the struck object is. Low values give tightly related modes that ring like a tuned bar or mallet instrument; higher values spread them apart into the inharmonic clusters that read as bells and metal. It changes what the object is made of rather than how hard you hit it. Per-sample, so it can be modulated.

• Brightness

  brightness
  Default 0.5Range 0 … 1

  How much high-frequency content survives the strike, by opening the filter that sits between the exciter and the resonator. Low values sound like a soft mallet on a damped body; high values are a hard stick with plenty of initial clatter. It shapes the attack far more than the tail, which is Damping.

• Damping

  damping
  Default 0.5Range 0 … 1

  How quickly the resonator loses energy after being struck, which is the decay length. Low values choke the sound almost immediately into a dry click or a woodblock; high values let it ring on for seconds like a bell or a struck bar. Together with Structure it is what decides whether the tile reads as percussion or as a tuned instrument.

• Accent

  accent
  Default 0.5Range 0 … 1

  How hard each strike hits, scaling the energy put into the resonator. Louder strikes are not simply louder — a harder hit excites more of the upper modes, so this also brightens the attack, the way a real struck instrument does. ⚠ Baked at build time, so it sets one fixed strike strength rather than responding to velocity while the patch runs.

• Sustain (bowed)

  sustain
  Default false

  Swaps the exciter from a single mallet strike to a continuous stream of noise, which turns the tile from struck to bowed or blown: it sounds for as long as it is running rather than decaying after a hit. ⚠ Baked at build time. With this on, Trig no longer starts a note in the way you would expect, since the excitation never stops.
