Sonar X2 & Kontakt 5 MIDI Routing - HELP! {SOLVED}

I am sure I am missing something really simple here!
 
I have loaded a simple "4 Out" instance of Kontakt 5
 
I wanted to create a Horn Section so I have loaded up the following instruments in Kontakt: Trumpets, Trombone, Tenor Sax and Alto Sax
 
I have managed to get my AUDIO routing sorted so that each instrument outputs to a separate audio track in Kontakt (I was pulling my hair out with this one until I found the option in Kontakt to automatically create separate outputs for each instrument!)
 
My issue is MIDI (and as a guitarist I am not that familiar with the world of MIDI!)
 
I have a controller keyboard that I have set to channel 1 - all of my instruments in Kontakt are also set to channel 1 and they all play together
 
I now want to set it up so that I have the different instruments on different MIDI channels so I can get them playing different things in the same instance of Kontakt
 
I have inserted another MIDI channel and pointed it to Kontakt - when my keyboard controller is set to channel 1 all the instruments play
 
However, if I set my keyboard controller to Channel 2 - and set one of the instruments to channel 2 - I do not get any sound? - eg I may want the trumpets to respond to channel 1, the saw to channel 2 etc.
 
What am I missing?
 
I thought this was how it was supposed to work so that I do not need to load lots of different instances of Kontakt??

Thanks JOHN
 
That was the thread I found last night via GOOGLE and was very helpful
 
I think I am doing everything you have explained in your guide - what am I missing in my approach above (which looks the same as your guide?!?!?!)
 
It feels like I am really close

Thank you soooooooooooooooooooooo much guys!
 
I had my EUREKA moment following your advice
 
I had originally thought the MIDI INPUT was where I needed to make the changes as I wrongly assumed this was the "input" to KONTAKT
 
I now understand (I think!) that the "input" goes to the Sonar MIDI track and I need to choose the "output" of the MIDI track to go to the relevant channel of KONTAKT
 
KONTAKT then outputs the audio, which I had routed correctly to individual audio tracks in Sonar
 
Have I got it?

Whats the advantage of doing it that way as opposed to having multiple instances of Kontakt running?  Sorry if that seems a daft question but it is genuine as I can't see the disadvantage of having multiple instances of Kontakt on a decent modern system as the actual amounts of memory and CPU resources needed are pretty small in comparison to the power available.
 
I can regularly have up to 10 instances of Kontakt open with some pretty heavy libraries such as Abbey Road Drums etc but it not even make a dent in my CPU or memory usage (16GB memory) according to the usage icons within Sonar.
 
I have had occassions where midi notes seem to stop playing but that wasn't confined to Kontakt and could have been any number of VSTi's but I foud increasing the midi buffer solved that problem. Am I missing something?
