Report from over here with Windows 7 64 bit, The track visibility feature is awesome, its going to be a time saver on big projects, the mixer looks cleaner, easier to read, the VST instrument rack now scrolls to the vst within any midi track you select, and its a nice look, refresh.
I didn’t have to copy any preset files from 7x to 7.5, , I just opened a 7x project in 7.5 and all of the presets appeared.
