Trigger

An attack / hold / decay / sustain / release envelope fired when the input crosses a threshold.

The Trigger node turns a crossing into a shaped envelope. Each time the input passes Threshold, the envelope runs.

Trigger

  • Attack, Hold, Decay, Sustain, Release times with shapes
  • A manual Trigger button
  • Found in the node graph under Modifiers → Value & Math
Example patch — drag onto the app to load

The image on the right is the example patch itself. Drag and drop it onto the app, or load it with File → Load, to open the full graph. The modifier drives the Scale of a Hexagonal generator; the meter on the node shows its live value.

Inputs and outputs

Trigger node

PortTypePurpose
InputModifierThe value to process, 0–1 unless the source says otherwise.
ModifierModifierDrag it onto a parameter row, or wire it into another modifier's input.

Parameters

Trigger parameters
  • Threshold (default 0.5), Trigger (fires it by hand).
  • Attack Time (default 0.05) and Attack Shape, Hold Time (default 0), Decay Time (default 0.1) and Decay Shape, Sustain Level (default 0.5), Release Time (default 0.3) and Release Shape.
  • Amplitude (0–1, default 1).

Every slider has a per-parameter animation bar and can itself be driven by another modifier.

Examples

Kick hit — a Sound modifier on Bass in, Attack Time 0.01, Decay Time 0.3, Sustain Level 0.

Troubleshooting

The parameter does not move — check the bound parameter's Operation at the port. At Multiply against a value of 0 the result stays 0.

It fires all the time — the input sits above Threshold. Raise it.

Related

Count

Count the crossings instead.

Combiner

Combines two 0–1 signals with Add, Multiply, Min, Max, Average, or Subtract.

Count

Tallies threshold crossings, adding a step each time, with an optional clamp or wrap.
