Hi:
I've been running Sonar 7PE on Vista 64 for two years with ok results.
I just bought a new Windows 7 laptop (I7 processor and 6G Ram) and
just installed Sonar 7 to record a vocalist 'live'.
It seems to be working ok... Audio works fine; Midi was a little hard to get
working until I logged in as Administrator. Then midi worked fine.
I'm not using a lot of tracks (4 or 5 audio) and a few midi tracks but it
seems to be working fine.
I'm using the Cakewalk USB 25EX soundcard
