Hey there!
I’m not super familiar with stack o bot and I’m not sure exactly what you’re asking so sorry if I miss that.
I’m assuming you want to audio to play based off the timeline location and not a simple start/stop. With that assumption in mind, you basically need to tell the audio to playback at whatever time you want it at. I forgot the node by name, but basically need to normalize the audio clip length from 0-1 and that will track along your timeline.
If you wanted to keep the audio playing when you release the plate, you just need to remove the stop, or add some extra conditions based on your goal outcome.
Let me know if your question was trying to achieve something else and I’ll see if I can still help!
