The easiest way to allow CC recording in session clips is by simply adding a new "absolute" envelope type to clips. This would NOT mean getting rid of the relative clip envelopes, they should definitely stay the way they are, IMHO (I enjoy having them because I can use them like an LFO).
Instead these new absolute clip envelopes would co-exist and interact with the relative clip envelopes, much like arrange view does to them already. So when clips are triggered in session view, their relative clip envelopes would follow these absolute clip envelopes.
The absolute clip envelopes could become arrange view automation when clips are dragged from session to arrange or when recording a session to arrange view. Also to promote backwards compatibility, you could have the option to turn on or off the absolute clip envelopes. This way when loading an old live clip or set that did not support these envelopes, you could simply default to having them turned off.
Anyway, to wrap this up my point is, if we ever get CC recording and absolute values in session view, I don't want to see relative envelopes disappear, and I don't want an option in preferences to switch between the two. We should have both at the same time
They can co-exist!
