I have Sonar 8 Producer Edition and yes I did look/ask in their forums asking for the same help, No dice. There is a function in it called apply audio effects that I am unable to use anymore. It is grayed out in the drop-down. I have never had this problem before and have not done anything out of the ordinary that I can think of. Anybody have any ideas as to what the problem could be or be able to help me? Short of re-installing it that is. Will do so if I have to but would rather not. Thanks as always in advance for any help/replies.
