RB is even better than that Allan. As I think you know, the chord grid controls what is generated. Since RB is a DAW, you can treat each track separately. That means you can generate a track or multiriff in this case, then go to the chord grid and change it. You might want to change the rhythm of the chords a bit or maybe different chord extensions or subs. After making the changes you can generate a brand new track without changing what you already did.

I do that with Real Drums all the time by changing the part markers. A part marker forces a drum fill so if you don't like some of the fills, change the part markers and generate another drum track. Then just for fun pick a completely different RD style and generate that.

These tricks can give you a whole lot of different variations to construct your song from.

The way I look at the differences between the two programs is Biab is great for instant gratification while RB is a full DAW that also generates Biab parts. You can spend a whole day with one song in RB if you're so inclined.
