Mal i think there is where yours and a few other frustration begins. There are some that want to finish a project in BiaB, but i do not think that was ever the intent of the program. It never was a DAW in the strictest since. It has always been marketed as auto-generation/accompaniment program. A creation tool, and a learning tool. That is why they build first Powertracks, and now RealBand. They are DAW software packages. Where one can take a BiaB creation and polish it up. RB is still young, and will grow hopefully, but for now if you want big time finishing tool you have to go to a deeper DAW package.
A good indication i am right on this is the fact that BiaB Mac still has no RB, and folks there are suggested to port over to something like garageband for finish creations.
Sure you can finish in BiaB, but that is like competing in the indy 500 in a stock corvette, fast yes, but not compared to a formula one car.
I certainly understand your views, and see what you are asking. But i believe you have a very long wait for what you want, if ever.
Our good friend Zero Zero has asked for a couple years now to blend BiaB and RB. IMHO he is missing the big picture here, and maybe you are as well. (maybe i am for that matter, it wouldn't be the first time) RB is that blend! A true DAW with the creation tools of BiaB added and True DAW features like FX busses, automation (now somewhat) Multiple tracks, and much more.
There is where your growth focus should be. If you want world class DAW tools from PG ask them to be added to RB. Not only does it blend the feature set of BiaB and Powertracks, it seamlessly opens BiaB files with out drop and drag. Just save, close BiaB, and open RB, open the file and it is all there ready to polish to your hearts content.
I appreciate your dialog, and i hope you do so in return. Regards, Rob
