I use both. They do different jobs.

So... if I write a song and use BB to give me a style I like.... such as hard rock, and it's a country song... I need instrumentation that the hard rock style does not give me in BB.

I normally get a few guitars, a bass and drums from BB.

But lets say I want steel guitar, fiddle, and dobro plus some nice B3 organ in the background. The only way I know of to get that happening is to open the file in Real Band and let it generate those tracks for me.

If you are totally content with the 5 tracks BB gives you, that's fine, but if you need more diversity in the final product, you should be using RB to fatten it up.

Add nothing that adds nothing to the music.
You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
