Hello, i've found the simplest way to get this at work is to open Biab AFTER that the keyboard is connected and turned on.
In this case, in "select ports" window, i don't need any changes: on "midi in" is rightly selected my keyboard, and ports on apple dsl synth.
The instrument i hear playing the keyboard is the one selected in"Thru" channel of course.
I've been doing this with an Oxygen too.
