Graham... I totally agree with you regarding NS's bass RealTracks... they were basically unusable to me. I do 90% swing tunes, and was so dissatisfied with the swing bass (& much of the guitar), I returned the 2011 package, and am back using 2008..

I do take offense at your statement "Just don't expect me to listen to the dreaded duos - keyboard and female vocalist with backing tracks - for longer than five minutes. I would rather there be no music at all".
I am a kybd player and my wife is the vocalist - our song selection, arrangements, and BIAB backing tracks are complimented at every gig by "non-pros" (as you describe yourself), as well as other REAL musicians. I would love to work with a bass player & drummer, but no one wants to work for $50/gig... So unless you are 'out there' as working musician....
