Hi
I have a Genos Workstation and that is the now .
The Yamaha driver is the same for the Genos as The CC121 controller. The controller works 100% in Cubase 10 and Win 10
There is no need for another driver yet until the new Yamaha keyboards needs them.
As long as Yamaha drivers get released the CC121 should work .
All the Best
