Audition 3, on Win7, I know it's old tech now but some of us still quite happily use Aud'3 for our sound production, which is ideal for occasional users. I recently tried to upgrade my interface and came across endless problems with compatability with win7, companys telling me I need to upgrade to win10 which I have on my office computer and dislike intensly. My editing suite which includwes Premiere Pro, which I purchased outright many years ago, works fine on my studio PC. after trying several interfaces which either would not work on win7 or crashed audition3. I finally found a new Behringer UMC202 HD, which has drivers as far back as winXP and actually installs and works first time with no problems.
