Elektron Musical Instruments

So, I just placed my order for an SF-60, but have currently and SF-6 on
loan.  

For the way my setup works, It would be ideal to have my master keyboards
midi merged to the output of the MnM, as it will be also used to sequence
other gear.   I have already checked, and on the MIDI tracks (channels
10~16) it merges input to output without any problems.   

On other channels, particularly channels 1~6 which the internal machines
use, it does not appear to be mirroring the input to the output, or in fact
sending any midi at all on those channels.  Is it possible to these tracks
to merge through just like the MIDI tracks do?  I am looking at getting a
MOTU MTP/AV to act as a MIDI router, so this is definitely not the end of
the world - just it would be overwhelmingly convenient if I didn't have to
give up the first 6 MIDI channels to the MnM.  

Thanks for any help you may be able to offer.
