thanks for the data. I had a look and things become clear now, but it needs a bit of explanation, so please bear with me.
Kontakt, similarly to HALion Sonic, is a multi player with 16 outputs and simply spoken, for each of the 16 Kontakt outputs Dorico creates one mixer channel in it’s own audio engine, so that via Dorico’s mixer UI you can mix and balance the levels of these channels.
Now, what sounds do come out from each of the 16 individual Kontakt outputs is managed by Kontakt itself and needs to be adjusted there.
When using HALion Sonic, each of the 16 slots is using by default exactly one output and also in that order, but in the HALion UI you can also change this and completely mess this up (what of course no one does deliberately.)
Kontakt however has by default a different strategy. It groups the first 10 outputs to stereo pairs and names these channels Stereo 1 and Aux 1 to Aux 4. The last 6 channels stay mono and are named Unassigned 1 to Unassigned 6.
So, 5 stereo plus 6 mono are 11, and that’s why in the Dorico mixer you see only 11 channels and not 16. Also, what sound now e.g. comes via Stereo 1 or Aux 2 is not under control of Dorico, but solely controlled by Kontakt and can only be changed in the Kontakt UI.
I hardly know Kontakt, I only have a very basic installation with just the player plug-in and NO sound library for it, so sounds don’t load here with me, and I can not tell what sounds would come through which output. Neither can I give you any advice of how to set up Kontakt in an appropriate way. I guess one would do in Kontakt’s ‘Outputs’ section; there click on ‘Presets/Batch Configuration’ and then choose ‘Batch functions’ > ‘Clear output section and create one individual channel for each loaded instrument’.
Maybe some other Kontakt user could step in here and give some advice.
So you see, it is a matter of setting up Kontakt properly. Most likely Dorico adds to the confusion by giving it’s own channels the names in the same order as it would do with HALion Sonic and we also have to change here some Dorico behaviour. I will discuss this with the London team.
And thanks for the hint with the existing diagnostic report not getting overwritten. We were not aware of that and will consider a solution.
