Connected s / 1 portable PC with Windows 7 to use one headset for 1 application DJ at Magix, with Asio4all drivers. Its very very good, a lot stronger than + Original Release my laptop, I am delighted. I made one update audio from my laptop at the same time elsewhere. Automatic and immediate install. One problem identified by using a different USB port than originally installed. Go figure what happens with Windows ... Ultra-fast delivery, well packaged and ultra !!!
