I’m a bit late to the party but I just started looking into the AudioProcessorValueTreeState stuff. I build a simple little plugin and everything works fine in Live, i.e., the slider will change the parameter’s automation level, and moving the automation level will affect the slider:
But it’s not working in Reaper?
Is there something I’m missing here? The fact that it works in Live leads me to believe that I have implemented it correctly but who knows. I’m using 5.4.3, and can make the code available if need be.
