Thanks for the quick reply David!
What you propose isn't really what I'm looking for.
Let's say I created a new RPC which holds my new variable Var01 which then controls a cue's volume.
The Var01 curve in that RPC consists out of 4 points.
I need to know each's points Var01 value and the corresponding volume value. So I can determine at which points I got the highest and the lowest volume.
I read through the docs and went trough the source code and everything and I don't believe that this is possible since this could also enable me to alter a variable's curve afterwards through code and that probably was never the XACT developers' intention.
Is there maybe another way?
