The SSD tutorial for Pro Tools will give you an idea how to do it. But things can get a little tight, if you dont understand it properly. The routing in PT is simple. As mentioned, you have 1 instrument track where your midi is on, (which in my case is the kick), after that i add 10 or 11 aux channels (dont remember exactly how many), you then route the input of each aux channel to the desired "instrument" which is held in SSD/Kontakt Player. After you´ve routed the snare, tom 1-3, cymbals LR, china, rooms etc etc etc, create as many AUDIO channels as aux channels, in that case lets stick to 11. Here´s the thing: The OUTPUT of every aux track (including the instrument track), is given its own BUS. Then simply go to your AUDIO tracks and give each INPUT the bus you want the desired instrument on. Check your levels going in, make sure they´re not too hot, and hit record.
Works like a beauty for me when using midi drums
Hope i (we) could help you out man.
