What you want to do is very easy in a DAW and since you have RB you should do it there. Place each prerecorded instrument on a separate track. That is one track for the bass, one for a guitar, etc. Then either mute the ones that you don't need or solo the one you do need.

I hope this helps you.


The fitness trainer asked me, "What kind of a squat are you accustomed to doing?" I said, "Diddly."
