You can create cross fades in take lanes, but the approach is different than using the parent track (or layers). See here:
http://www.cakewalk.com/D...;Req=Arranging.46.htmlThe trick is the two takes need to be completely adjacent - no gaps. If you slide one take over it will delete the corresponding section of the overlapping take. Then, use the take cross fade tool to adjust the size and location of the fade. In some ways it is actually better than layers. In other ways not quite as good. But certainly useable.
I wish CW would provide more video tutorials about editing with takes. It is possible to do it effectively, but the documentation is weak.
