Logic Pro X Logic X with Behringer X Touch

I would greatly appreciate what your thoughts are for using the Behringer X Touch and or mackie control in MC mode with Logic X, and if their are issues and how it is working out? I am on Logic 9 with the X touch in MC mode with usb.. It is mostly working well but sometimes not all functions for MC mode are working as should. What OS is best for the X touch?

Thanks, Jim
I have no answer for you. I use macOS 10.12, Logic Pro X 10.4.1 - it works fine. I wind up opening the manual a lot. Learn a lot of things that way. The Mackie Control chapter of the Control Surfaces manual is the place to look.
Thanks. Yes, I am using the manual a lot. Also interested in hearing from some people who may have moved from Logic 9 and the improvements if any that they may see as well as X Touch users.

Thanks again, Jim
