its tough switching to any new version when making jumps over versions, specially when jumping from sonar 7 to x3.
but for the love of technology, you will find so many hidden gems in the newer versions.
cakewalk has seriously stepped it up in newer versions.
old habits die hard but the amount of extras packed in with the new features, it will take a bit to get used to.
with that being said, the groove 3 videos will help you get up to date on new features (including smart tool)
it was tough for users when X1 came out because it was a total revamp. so jumping from 7 to x3 must be a little difficult.
sure you know the ins, and outs, but to anyone this would take a bit to get used to,
have faith and have fun ;-)
