The Playback State Node is a simple Node that outputs a signal indicating whether playback is active, as well as a signal indicating the current time on the Timeline.
Outputs
Playback State Output
A signal that’s set to a constant 1 while the project is playing, and 0 while it’s not. The output is a constant 0 while not playing, which you can use to optimize around Nodes that support constant folding.
Current Time Output
A signal indicating the current time, based on the playback head position on the Timeline. This value is in beats, meaning that for projects with a BPM higher than 60, it’ll progress faster than seconds, while for projects with a BPM lower than 60, it’ll progress slower. You can use the Project Info Node to account for this.
