I have purchased Presonus Studio 24 USB interface to use it with Cubase 5 instead of my old sound card.
I was able to setup the in and out audio signals in Cubase, but I can't get any MIDI signal from my Keyboard (Kurzweil SP76). It works fine with the old interface.
I have also tried to install Studio ONE, which took me a lot of time, but no MIDI signal is coming through there too.
I am using Windows 7 64-bit ultimate SP1.
