Hi
Yes we can.
The insert send/direct out setting is global for all mic/line channels only. your LR mix is still post all processing from every channels (fx returns etc..)
“(that means in case of multichannel recording CH01-18 which in our case CH17-CH18 is the stereo/LR rec)”
No. That means your 01-16 in qu-drive will be dry (because mic/line inputs 1-16 are patched) and 17-18 will be your LR as always post everything
For example: if you decide to change and patch your ST1 in the qu-multitrack 17-18 ,in this case 17-18 will be dry
I could explain much better but my english sucks..sorry for that
