To have one bit of software the accomplished both to a highly professional level is, perhaps, a little over ambitious (or greedy even)?
So where does FCPX stop before it hands over the audio baton?
Perhaps right where it is?
Maybe we should be content with a whole new NLE that takes us just so far before we hand over to Pro Tools, Sadie, Logic?
Maybe ditto Color?
Incidentally I do not know anybody (in my circle of colleagues and friends) who uses Logic for audio post here in the UK (Music composition yes). I guess people do but to what extent?
Do you people use Logic for audio post much?
