I must confess that though I love PT12, I rarely use Real Band! If I want to hear how a new song might sound, I certainly play around with the styles in BIAB (now using 2009.5) and I might end up importing something into PT for further meddling ... but I've never been much attracted to Real Band. I have tried using Real Band, but it didn't seem as useful as either BIAB or PT for the things I needed to do.
