What you are seeing here is exactly the type of reason I switched away from Real Band.
I watched a few of the "how to record your band" videos on Reaper.fm and everything seemed so easy and trouble free.
I installed the 60 days for free version of Reaper and never looked back.

of course that is only my experience, but the Reaper videos walk you through everything so easily.

Maybe there is similar stuff available for RealBand but I never found it.
