Seriously, Kontakt's multi-output handling is just terrible, over-complicated and weirdly implemented.
What you'd expect to do:
- Load a multi-output Kontakt in your DAW (say, 8x stereo outputs)
- Create whatever additional mixer channels you need in your DAW to handle the Kontakt outputs
- In Kontakt, assign the kick to Kontakt output 1+2, the snare to output 3+4 etc... job done!
What you *actually* have to do:
... you know what, I was going to step by step the procedure but it's so unbelievable it would take me 12 paragraphs. You basically have to nuke the initial configuration (which probably has a few stereo outputs and a 5.1 surround config - useful!), and create a new bunch of Kontakt outputs, and map them to the *actual* plugin outputs.
But the list won't update until you make the new configuration the default, and remove and reload the multi-output Kontakt (yes, you make changes to the output config, you have to reload the plugin!). Now the list of available outputs will be correct, and you can now map (*sigh*), the Kontakt outputs to the host output channels (so that, eg Kontakt Stereo 1 is mapped to Outputs 1+2, Kontakt Stereo 2 is mapped to Outputs 3+4 etc - yes, you have to do this manually for no on godly earth reason.
*Anyway*, once you mapped all that stuff, and saved it as an output configuration preset, you can probably now load your actual Kontakt instrument, and assign your Kick to Stereo Output 1 (which we've told Kontakt is the plugin output 1&2) and so on.
Once you've got a working config saved, it's fine, but if you're not familiar with it, it will do your head in. I still find it fairly unbelievable everytime I go back there and look at what you have to do...
