The Gate Node (GateNode) acts as a dynamic ADSR-style envelope filter and peak trigger. It passes incoming signals only when they exceed a configurable threshold, smoothing transients with Attack and Release timings across scalar or multi-element sequence streams.

Gate Node

⏱️ Dynamic Envelope Parameters

  • Threshold (0.0 – 1.0): Minimum input signal level required to open the gate.
  • Attack (ms): Time required for the output to reach 100% after the threshold is crossed (e.g. 5ms for instant flash, 200ms for smooth swell).
  • Release (ms): Decay time for the output to fade back to zero after the input drops below the threshold. Eliminates harsh flicker and creates natural light decays.

🌊 Sequence Support & Independent Element Envelopes

GateNode natively supports sequences on its Signal In socket:

  • Polymorphic Signal Processing: When fed a single number, it operates as a standard scalar envelope follower. When fed a sequence, it automatically processes each element in the array.
  • Independent State Tracking: Envelope state (current attack/decay ramp position) is tracked independently for each element in the sequence. A peak transient on element 0 will not open or reset the decay curve of element 3.
  • Uniform Temporal Dynamics: The Threshold, Attack, and Release inputs remain scalar to ensure uniform envelope dynamics across all fixtures in a tag.
