Hello, the 5.5.1 help for logic says that you can use the velocity line tool to make relative changes (that is the new velocity value is an average between the current value and the line value) by clicking on right mouse button instead of left. I've tried several times but it never worked . Any hint? I think it's a very clever function, and it's even documented, so why is does not seem to work? I am using logic 5. 5.1 on pc and the velocity line tool from within matrix editor. Thanx and bye
