How to pass 'trigger notes' from controller to DAW?

[MKS30]

So you want the MIDI note data sent to MIDI out B as well as A, or just A OR B, but not both? If both is OK you can send it to ch1-7 ALL, but this will send on the 4 USB ports as well, so just be aware of that.
If I'm not understanding this correctly we may need a deeper explanation of what's being connected downstream and where clock is coming from and going to, etc.

USB will be used only for power 

The goal is to have ch1-7 and ch15 (from controller) to exit on either MIDI A or MIDI B (I'm only using one of them)

I'm sending ch15 to both MIDI A and MIDI B, in the hope one of the MIDI ports will pass it

Thanks
