Realtracks have never been midi or quasi midi at all, they are true audio. They are just somewhat akin to loops and are dice and slice and reconfigured to the tempo, bar, and chord settings.

Real track generation is the same in Bb or Rb, it is just that RB does not regenerate each time you hit play like BB does, it freezes the track until you tell it to regenerate.

To put all midi in Rb, simply do not make real tracks, just make midi tracks in BB. They are not the same. The only midi associated with a RTs is the one that generates notes for the real charts. Also you can have Rb generate midi as well you do not have to make RTs and RDs.

As far as tempo changes i will let someone else answer that one as i have not used that feature.
