Sonar Artist - routing midi 16 channels TTS-1 or SampleTank

I would like to link/route midi channels to TTS-1 or SampleTank.
I am checking tutorials on youtube that show a little different interface and seems simple but when I try to do
it in Sonar Artist, it doesn't work.
All midi channels I have go to Channel 1, I would like to route to other Channels 2-16 in TTS-1 or other similar.
Regards,
Kris.
