Hi. I upgraded and then found that the faders on my CUPro started to fight my fingers. Also the blue back-light went out.
Mine is only a year old. I had read of others having problems too but the light that went out was different.
It has a 2 yr warranty with Mackie. They weren't telling me whether it was the update or not.
I sent mine back through the store I had purchased it from and it'll take 2 weeks for it to return.
Funny though, it coincided with the upgrade, before that , it was truly seamless interaction with Logic.Good job I have Automap 3.4 and it works great with the Remote SL.It's not quite the CUPro though.
All the best.
