Purpose

Trigger Watch turns a signal into a cue. It watches one control lane, and each time the value crosses your threshold it sends a trigger event. Whatever can produce a control lane can now fire a cue: an audio analysis, an automation clip, a value pushed from the host.

Use

Wire a control lane into control, set Threshold and Direction, and send obs into Arrangement Source’s trigger input to release a held section. It also works as an input to Transport In’s obs.

Inputs and outputs

• Input 0: control the lane to watch. Required.
• Output 0: obs trigger events. One per crossing.

Controls

• Threshold: the level to cross. Default 0.5.
• Direction: rising, falling, or both.
• Armed: while off, crossings are ignored.
• Latch: fire once, then stay quiet until Reset.
• Reset: pulse to re-arm a latched watch.
• Statekind: continue sends a GO. play sends a play. Arrangement Source treats both the same.
• Sourceid: a number, 0 to 255, that tags the event. Default 7.

Notes

• A rising crossing is a sample below Threshold followed by one at or above it. A falling crossing is the reverse.
• The first sample after start never fires, since there is nothing to compare against.
• Without Latch, a value that hovers around the threshold can fire repeatedly. Smooth the lane first, or turn Latch on.
• Reveal channels: fired, value, armed, and latched.
