CakeLab Now that's the best one yet.. did you come up with that?
I have screen shoots in my tutorial on how to use a VST. see my signature for the link.
I've never used Kontakt not even sure what it is but I know lots of people here use it.
But it sounds like a multi channel VST.
I use Airs Xpand2 and it has 4 instruments available. So that might be similar
So you insert 4 midi tracks.
Set the outputs to Xpand
Set channels of each midi track to ch1 thru 4.
Now load an instrument into the 4 places in Xpand and make sure they are turned on and the volume is up.
You can set the banks and instruments in the track inspector or use the GUI. If you use the GUI make the track inspector boxes for Bank and Instrument NONE.

Chris it's easy to post screens shots.
I have One Drive set to store all screenshots. Drop box also does this.
I then use Imgur to upload those.
Then post the link from Imgur. Takes less than a minute.
