Kontakt, while not being fully integrated with the Komplete controller boards, does indeed allow via multi-rack and multiple instruments at one time - great composition tool. I've heard of FreeStyle which somehow creates a multi-rack in the Komplete Kontrol interface. Not just one-off sounds/loops with effects, but multiple channels of output controlled with multiple midi channels like Philharmonik 2, Play(East/West), or similar. Nonetheless, I utilize the Kontakt multi-rack setup in Cubase and it works great! I have the one VST for Kontakt in my session with over 12 MIDI tracks pointing to it btw, all routed to separate channels. Only using 5% of my i7 quadcore processor on a PC under Windows 10 and minimal disk usage thanks to 32GB ram. Great to stay in MIDI till time of mixdown, especially for film where footage can change in the middle of a scoring project. Instead of any re-printing nightmares of printed tracks having to reprint due to a tempo change, it is all seamless in adjusting in the MIDI environment on my DAW, with full usage of my effect plug-ins on the channels and almost no latency. It has made turnaround time a breeze. I wonder if NI is planning on merging the Kontakt and Komplete Kontrol interface technologies.
