I've uninstalled all programs that I could imagine using MIDI ports, but every time I try to connect my MIDI keyboard over USB to Reason 4, I'm told the ports are in use by another program. I'm using Windows 7 x64 and the appropriate drivers, and the hardware works just fine on XP x86.
Keyboard is a Roland PCR 800, and soundcard is Creative X-Fi Titanium, all drivers up to date.
