I bought Sonar X3 and never really got comfortable with it. Plus, I noticed the plugins weren't accessible by BIAB anymore. (in version pro audio 6.0 they were)

So I reinstalled the old 6.0 version. It works fine in win 7 and is rock solid. An added bonus is that the layout is remarkably like RealBand, so I rarely have to search for anything.

I think I've hit the age where changing things just because there's a new version has become counter-productive for me.
