Eucon 3.5 extreme CPU load

[quicksandjezus]

Hello everybody,
I post my question here because I do not know where to post it else.

I upgraded my mac to OSX sierra and use 3 artists series controllers.
I also upgraded to eucon 3.5 and did the firmware upgrade for my controllers.
So far so good, its working good, but
my mac runs on max fan cooling when eucon 3.5 runs.
As soon as I kill eucon its back to normal
Can not fined anything on the net about it.
Anyone ideas ?

Thank you.
