PS: One thing I couldn't seem to find a clear answer on, related to this topic--Is it possible to have clips in more than one take lane sounding at the same time (à la layers)?
Absolutely. I wrote
an article about this for Sound on Sound. (Full articles are only for subscribers for six months, but after that anyone can read them.)
I take advantage of this in two main ways: To create big, stacked background vocals, and to add occasional one-shots to a loop to add interest.
As to general pros and cons, there have been lots of threads about this, but some of them have posts that draw conclusions based on not understanding how Take Lanes work. For example, the biggest difference to me is you can't crossfade within a Take Lane, but you can crossfade between those same clips in the "parent" overview. You can also put overlapping clips in two lanes, and fade one out while the other is fading in, or use the DSP menu to create crossfades.
There are also some layer management commands that are no longer available, and another issue with Take Lanes is numbers always increment. For example, suppose you're comping the verse in a vocal track and do 7 takes. Now you have 7 take lanes. So now you want to comp the second verse. This comp will start on take lane 8 so if you do 7 takes, now you have 14 take lanes. Of course you can drag the second set of clips into the first set of lanes, but some people find that inconvenient.
My "take" is you trade off a little bit of the functionality of layers for a HUGE increase in comping functionality. The comping is amazing, and you can still do most of what you did with layers using Take Lanes. Given a choice between one or the other, for me the X3 implementation wins hands-down.
