Hello,
I’m trying to implement a music system using labelled parameters in UE4.
Thing is, in blueprints, the set global parameter and set parameter nodes can only receive float values and no string values.
Is there a way to input string value to change a labelled parameter ? I’d like to avoid remaking my interactive music with float values only.
You can see the float values for your labeled parameters in the Edit Parameter window on the right for each label entry:
Use that values in blueprints 
I tried that but it didnt seem to work. I’ll try again when I get back to work ! Thanks for the answer.
Currently you can only set parameter values in game by float, not by string value.
Has this been resolved in current version for UE5? We were wondering the same thing just now and can’t seem to find an answer in the documentation.
Currently it is only accessible via code, I will bump the task for adding it to blueprints and see if we can get it added to an upcoming release.
