Asio driver Roland TB-3 / Cubase Element 8 / Mac El Capitan


I am encountering an issue while using Asio driver from TB-3. The transport speed is twice as quick as the real tempo. When I go back to internal sound device of the Mac everything is ok.
Any known issue about that and any workaround ?

To be more specific :
Cubase element 8.0.35 (565)
Mac OSX El Capitan 10.11.04
Mac Book 16Go RAM
Driver Roland TB3 downloaded from Roland website two days ago.
