Here's my old post on Take Lanes:
http://forum.cakewalk.com/FindPost/2969645 I use Take Lanes to record my vocal, but I often use separate vocal tracks for each section of a song. I just find that easier to sort out. Then I move or copy the best clips into a single vocal track for further processing.
I use the new feature, but the Take Lanes did/do take some getting used to. Every take will be there, in it's entirety, but you do have to sort them out afterwards. If you stopped one take midway through the loop for example, the clips in the other takes are split at that point. But, in those previous Take Lanes both of those clips still contain the entire previous take. You can move and slip-edit either of those two clips and the whole take is there, in each of them.
The first time I used Take Lanes and I ended up with all of those duplicate clips I was thoroughly confused. Maybe I still am:) But, that's why I sometimes use separate tracks for separate song sections, easier for me to organize.
You can add more blank Tank Lanes and then move the clips around and delete all the duplicates that were born once you have them sorted out. It was during that process I started to understand Take Lanes.
