I used to use Music Works 2.3 and found it excellent, but it seems to have been superseded. What is my best route to get going again?
I've looked for this application and it's still available, only that it has been updated to version 2.6 where new features have been implemented and bugs fixed. I strongly recommend downloading the latest version if you previously used the application and found it comfortably.
