Thanks everyone. You've given me a lot to think about.

I guess it depends on the definition of "backing tracks". By strict definition that's what I am looking for. But I don't want boring, uninteresting backing tracks. I want something that, along with myself makes more a complete musical experience.

I have been also considering performing live with whatever I end up using. So I don't know if Reaper or Calkwalk can handle that?

When I really think about it...my music may lend itself to looping, layering, etc. I envision longer improvised sections. Something more interesting than the straightahead jazz I've done in the past, yet not as formulaic as smooth jazz. And not as far out sounding as electronic music. Probably more through-composed than typical song form.

I'm sure I'll have a better idea after I really dig in to BIAB.

Re: skating metaphor. It sounds like you are saying that the real art happens in BIAB and everything beyond that is frosting on the cake?

I like the idea of having a Ferarri...if only I knew how to drive it.
