If you have "arrange track 1" (not "cha track 1") assigned to object A and "arrange track 2" assigned to object B, and object A & B are assigned to "cha track 1", then automation on one arrange track will affect the other but it won't be obvious why. Go thru all your arrange tracks and make sure anything that looks like it's assigned to the same object truly is assigned to the *same object* in the *same layer* of the environment. Because of this flexibility in the environment it is possible to have tracks which have different, even conflicting, automation controlling objects which are essentially the same. But different. Oh, don't forget to check for hidden tracks which may be contributing to this behavior. Is that clear? Let me know, it can get confusing. u b i k
