I want to make an orchestral composing template using the Nucleus sample library/VST.
My problem: I am able to route the different instruments in one Kontakt 8 Player instance to the different mixer tracks in the Kontakt Player, but am unable to route the mixer tracks in the Kontakt Player to the mixer tracks in my DAW (FL Studio). At the bottom of each of the mixer tracks in the Kontakt Player there is a small box which indicates the output channel (first mixer track: 1I2). When I want to change the second mixer track to 3I4, however, the only plugin output channels showing up are "01 Unavailable plugin output" and "02 Unavailable plugin output", which are the outputs already in use by the first mixer track. In the plugin settings in FL Studio there's also only one output showing up which is called "1. Output 1" (see below).
I have watched many videos explaining how to route the mixer in Kontakt to the one in FL Studio, but none talk about my issue. I have also completely deleted and reinstalled Native Access and Kontakt 8 Player with no success.
Is this a common problem? What can I do to fix it?
Thank you in advance for your help!
Here are some screenshots of the DAW:
