Hello I have an Behringer 1920 asio interface, and that works fine. Then I have a yamaha psr 473 that has an inbuilt soundcard. I have installed the steinberg asio driver, but in cakewalk I cannot use it. In preference "in and out" the steinberg interface is grayed out so I can not click it. And under drivers there is only asio.. How can I activate the steinberg 1+2 in/out so I can record sound from my yamaha arranger? Claus
