Kontakt is designed to be used like that.
It just needs the option to set the keyswitches of any octave on your keyboard.



You can try it in Reaper (even in Linux) this was made just to test the theory out it uses some support scripts, I will see what PG do else I will put some more work into it to be a self contained script. It works great with the BB Plugin as you can have lots of Plugins for more material than 255 bars (if the Plugin is made self contained it will work with Linux).
