I'm at a loss to understand why audio effects are explicitly disallowed as source effects. Audio isn't just an obvious use case for source effects — audio is an absolute pain to manipulate otherwise.
Say I have an audio recording that needs some processing applied wherever it's instanced in sequences. I really want to be able to apply such effects non-destructively, but as soon as I cut the clip up, I've got dozens of individual clips that have lost their effects connection to the source.
I guess I have two options at that point — to destructively edit the source in Audition, or to create a whole extra sequence to enclose just that one source file, to edit the effects in the sequence's one, unbroken, clip, and then nest that wrapper sequence within my actual target sequence, and chop it up rather then original source clip.
This seems like a really backwards process. Am I missing something here?
