In Kontakt you can load multiple instruments in the same plugin instance and set them to different channels. You can then use keyboard split mode in the Komplete Kontrol keyboards to play each separately using a zone on the keyboard.
EDIT: I wish to do the same with Razor in Reaktor, NOT Kontakt...
I'm aware Komplete Kontrol can't load multiple instruments, but I was hoping to to do something similar by loading multiple instances of the Komplete Kontrol plugin in a single track of my DAW (Reaper), and then assign them each a unique MIDI input.
I don't see that this is possible so far. Am I mistaken?
I wish to do this because I'm setting up a single project that will contain a full set list of songs to play live. To keep the size of the project down, I want to load each song into it's own track with all of the instruments that should be played live for that song. Ideally, I might even load all the songs into one track and use automation to enable/disable the instances of the plugin.
I was hoping to use Komplete Kontrol to do this because you can load an instrument AND additional VST plugins in the chain, such as an EQ to hi pass the output or reverb and compression. That would mean I could simply enable/disable a single KK instance and not accidentally leave on the EQ, reverb, or compressor on, affecting the new instrument.
Unfortunately, if I can't choose the MIDI channel manually, I'll have to make a single track in the DAW for EACH instrument (perhaps 4 per song), and EACH song in the set list so I can mute/unmute tracks as needed.
I would end up with like 50 tracks to manage just for the keyboards... which isn't ideal.
