Threads with Changed()

Does anyone know if Changed is synchronous, or asynchronous? Cheers.

changed()is guaranteed to run on the scripting thread. So if you call if from within the scripting thread, it will be synchronous, otherwise it will be asynchronous.You can confirm this by using Perfetto and this snippet

@Christoph-Hart Thank you, and what I was hoping. If I could pls ask a follow-up — how would it not be called from the scripting thread?
-
@Christoph-Hart Thank you for the example. I must be doing this wrong…

Synth.deferCallbacks(false)will make the onNoteOn callback run in the audio thread. The other scenario is custom LAF which will be executed synchronously in the UI thread but if you callchanged()from within a LAF function then you deserve all the pain it brings to you :) -
@Christoph-Hart Understood and thank you. However, when I call
changed(), execution appears to be asynchronous, and if I call the control callback, explicitly, execution is synchronous. I may have misstated my question. I can upload a screen movie showing a simple example. I will add that I'm doing this during the loading callback with a custom preset manager. (It's not during onInit.)EDIT: I have a movie but the screen movie "exceeds the pixel limit" for an upload. The screen capture is 50% of the built-in display on my Mac laptop.
Somebody please fix the forum. I will help.

I'm aware lol, it just doesn't seem to work on my end. (But that's a different affair.) Thank you again for taking the time to write that snippet.
