Great!
Thank you very much!
I was testing it on a bigger project with a piano track with many many notes and, even if I selected only a few to modify with the script, I could hear a lot of cracking sounds when dragging the control if it is playing the track. Not a big deal. But maybe it can be optimized to run in lower priority or something? Maybe it is just the way EEL scripts work.
How can I have the script window on top of the midi editor window? When I go and select other notes, the window disappears behind the midi editor window. It needs the little pin button
