Thanks for your feedback Steve, and in general what you're saying is absolutely correct. But I thought my very narrow question with these particular types of apps may not conform to the generalization.

My understanding was that the applications have to specifically be coded to use more than one core, otherwise they can ONLY use one.

Now, I named 3 different pieces of software - and generally, one would think that SEPARATE applications that run simultaneously would naturally use different cores...but with add-ins and virtual instruments, and software that works in an integrated way, I wasn't so sure this is possible....I think the only way to know would be to be the developer - or - as you very well may have - to watch how many cores are working at the same time as you simultaneously run BB, digital recording, and loaded VI's at the same time.

I don't know - maybe I have overcomplicated it - but I think it's possible the multiple cores are not used as much as you would hope given these 3 music apps.
