You can actually pass the midi messages straight through the octa without having to have a midi track selected.
The trick is to not use the Auto Channel.
Just set the midi channel on your keyboard to the same channel as one of the midi tracks on the octa.
It has been discussed in this thread previously. You might find some tips there: http://www.elektronauts.com/t/setup-ot-master-a4-slave-midi-keyboard/1242
