I know this thread is old but for the money of buying Kontak 5 full version vs Komplete 10 was only a $100 difference, so I bought Komplete. Now I have a separate question does anyone know how to setup Kontak5 so that you can assign 1 instrument per track in Sonar?
If you load up an instrument in Kontakt you can choose its MIDI Channel. You'll see this near the top of the instrument's screen where it says "Midi Ch:" As you're loading the instruments they should automatically become assigned to [A] 1, [A] 2, [A] 3, in order. But if you ever need to change this you can just click the arrow and do so in the drop down box.
Let's say you want to load 16 different instruments in Kontakt and have each instruments assigned to its own track in Sonar. Creat 16 MIDI tracks in Sonar, then load your 16 instruments in Kontakt. Assign each Midi track's Midi channel to the corresponding Kontakt instrument's Midi channel. That's it. Now, when you click on your first Midi track in Sonar and play some keys on your controller, you'll get the sound of the instrument that is assigned to Ch. 1. Likewise for all the rest.
Semi-related: a neat little trick you can do if you want to experiment with controlling multiple instruments at once is assign more than one Kontakt instrument to the same Midi channel. Then you can play your keyboard and get the sounds of multiple instruments at once. This is good for when you want to write parts in unison for different instruments and want to hear how it sounds right away. When you're ready to record the takes I would recommend reassigning them to their own channels so that you can process them separately, though that's completely up to you depending on what you want to do.
