well at least I can see you had fun testing it
Thank you
I don't know what can it be... I'm trying with different undo settings now. Something is screwed in my REAPER then. Undo works perfectly until I add the dpmeter plugin. First undo works. Second undo freezes everything.
These are the only plugins I have found that export the loudness values to a parameter that can be read from the script. So... It's sad I can't make them work.
