I updated to X1 from Sonar 6, which I think was quite similar to Sonar 5. I even got a Sonar 5 manual with it, with a half page update.
What is it you find so terrible?
It realty threw me at first, but after reading the manual and trawling the forum, it was fantastic. I can't believe I stayed on 6 for so long. It genuinely is worth persevering.
