Pro Audio 9 and Windows 7 Professional
I've taken the Sonar plunge but anytime I need to do some serious midi edits I go back to Pro Audio 9. I tried to install Pro Audio 9 on a Windows 7 machine and the install failed. an uninstall fails as well. I'm using a Dell desk top, pretty standard dual core, lots of memory and disk space, and using Windows 7 Professional.
Those who do often, do well.
