Apologies for butting in Matt, but converting a RT to midi is something I tried recently and managed to get to work.
In version 2014, what I did was to drag the track to the midi quadrant of the Drop Station.
In the below example, I've selected the Piano track (since it has a green underscore) and dragged it across.

Once the item is processed, by right-clicking on the Drop Station icon, it's possible to copy the midi file to a chosen folder.

As Matt has already mentioned, if a RT doesn't have a green underscore, this will not work.
Hope this helps,
Noel
P.S. Sepheritoh and Graham, if you want to read a little more about it, have a look at page 9 of the New Features pdf that came with BIAB 2014
