Hi [USER=“70000”]Abbie Doobie[/USER] , at the moment it is not possible to change time signature and/or pulse override after they’ve been set.
A Clock’s Settings input is only available on the Create New Clock node, and that’s what you’d need to do :-/
From what I understand though, the devoted Epic audio team plans on putting some improvements in with 4.27, which will make it possible.
You can however change Beats Per Minute or Ticks Per Second etc, on an existing Clock Handle. I believe it would jump to the new speed on the next bar (or is it next beat?).
In my use case I wanted to keep the BPM, with a click playing 1/4 notes, but change time settings to allow other sources play different accents and patterns.
So what worked for me was : OnBarEvent > PauseClock > UnsubscribeFromAll > CreateNewClock with new Settings > cache it > SetBPM to the same float > Subscribe to those 1/4 notes > from that Delegate Create the same Event already in use for the click > Resume the new Clock.
This way it stayed on the beat, with time count and subdivisions changing in the background.
Surely it’s far from ideal, so when you find a better way please let me know… best of luck!
