I know that there is a phase switch in the mixer channel strip, but if not,  is there a phase meter or software planned ??

Search on "goniometer vst plugin freeware" and you'll find plenty of options for correlation and phase meters. I'm using the Gonio3 by uk-music. I don't think there's any real need for CW to spend time developing one when there are already several that don't cost anything.

Thanks !!

The reason I'm asking is that on another forum, I posted some samples of a stereo recording on a guitar, and some of the posters mentioned that the recording was out of phase. With the help of Adobe Audition, I traced it down to some bad XLR cables, and have the problem ironed out now. There is a phase meter in Audition. I was just wondering if there was one in Sonar as well, so that I could double check my recordings in Sonar.

I have to take that back, upon further re-testing of the XLR cables they test out okay. Something else was causing a phase shift.

A phase meter and phase correction software would make a wonderful Pro Channel  module.
