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/Control | The Audio/Control signal to which the ADSR sequence is applied when the Trigger input receives a value above the Threshold setting. |
|---|---|
| Trigger | The trigger input. When it receives a value above the Threshold setting, the ADSR sequence is started on the Audio/Control input. |
Settings
| Threshold | Sets first input’s audibility duration. |
|---|---|
| ADSR | Sets 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/Control | The 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.
