There are two main reasons I have not put more effort into RealBand...

- for some reason RealBand seems to load my projects very slowly. A project that loads and generates in about 10 seconds in BIAB takes 90 seconds to load and play in RealBand. And if I export my tracks into Reaper the project loads and plays instantly (of course I understand it is not generating RealTracks!) With my current workflow, by the time I get to the DAW I'm pretty much done with the BIAB functionality so for me the extra processing is just not worth the wait. And in some ways having my DAW regenerate tracks is actually a drawback to me since I do not typically expect a DAW to be changing my tracks on its own!

- I really do not care for the RealBand interface. And this is not just a visual thing. I have found things in both the BIAB and RealBand interfaces that are not up to modern GUI standards and these things interrupt my workflow. For example, in Reaper when I place my cursor over the scroller to the right of the project the mousewheel activates the scroller but with RealBand the same action zooms the project tracks. Another example, I click a track and apparently I accidentally moved the mouse a smidgen and RealBand gave me an unexpected error message, in a bright yellow (DOS-like) window with grammatical errors in the message ("Track contains no music, so it can''t be dropped outside of Realband")! I have other examples but you get my drift!

I don't mean to nit-pick and I realize these GUI issues may not be major for some but they do affect my confidence in the program. I think few would disagree that BIAB has an outdated GUI but what is does is so amazing I am willing to accept and work around that but I don't need to make that compromise with a DAW.
