As of October I finally have been able to get my Zoom R16 working as a Mackie Controller for the Cakewalk program. I am not sure
why it is now fully working but this morning I updated to the latest Cakewalk. I also updated my Zoom R16 Firmware and Windows 10 drivers from the Zoom site.
I uninstalled the old Windows 10 Zoom driver and reinstalled the latest and clicked the install sonar plugin while doing so.
The helpful instructions above from other people are correct re choosing track inputs. But still the Zoom R 16 would not work as a Mackie Controller even though it was listed in the preferences as the controller. I deleted it in the Mackie Controller section of the Cakewalk preferences and added it again (see top right of Macke Controller preferences for Delete and Add). Don't forget to click apply down the bottom of course.
When I added Zoom again as the Mackie Controller it worked!!!
