Gate Node

Trigger-able gate Node. When the Trigger input receives a value above a certain threshold (configurable), an ADSR sequence is started, applying a gain change to the Audio/Control input. This is useful for building custom instruments.

Inputs #

Audio/ControlThe Audio/Control signal to which the ADSR sequence is applied when the Trigger input receives a value above the Threshold setting.
TriggerThe trigger input. When it receives a value above the Threshold setting, the ADSR sequence is started on the Audio/Control input.

Settings #

ThresholdSets first input’s audibility duration.
ADSRSets an ADSR envelope (Attack-Decay-Sustain-Release) to automate gain on the input which receives a threshold-exceeding value.AttackAttack is the time taken for initial run-up of level from nil to peak, beginning when the key is first pressed.DecayDecay is the time taken for the subsequent run down from the attack level to the designated sustain level.SustainSustain is the level during the main-box-for-contents sequence of the sound’s duration, until the key is released.ReleaseRelease is the time taken for the level to decay from the sustain level to zero after the key is released.

Outputs #

Audio/ControlThe Audio/Control signal to which the ADSR sequence was applied when the Trigger input received a value above the Threshold setting.

Technical Details #

This Node has up to 256 samples of latency.

Limitations & Known Issues #

Currently, latency can occasionally increase above 256 samples during live playback, when a heavier task is being carried out in AudioNodes. This problem is not present when rendering to a file from the Export page.
