How to update: Please launch and log in to Command Center. You will then see a dialog prompting you to update Command Center. Please perform this update first. Once Command Center relaunches, please click on SONAR Platinum. You will then see the "Update" button, which you can click to install the new update. Next click on Anderton Collection and click the "Update" button, to download the latest amps. Enjoy!
 
However, I'm not seeing the update button for the Anderton Collection. It just says reinstall
 

Did this actually roll out a few days ago? I got an update....I think two days ago.
 

That was build 252 I believe. This is build 254. I never got the Update button next to the Anderton collection either so I am assuming the other update handled it. I tried re-installing it. My version shows 1.0.0.7.

Yes, build 254.
I just checked for updates and the Anderton collection was there this time. So I guess I'm good.

Yeah, it was done today for the public release.

So what are the changes in the new 254 version?
 
Andrew?

Per the email sent from Cakewalk "The new update addresses an issue with Melodyne that was being experienced by some users. In addition, the Craig Anderton CA-X Amps that were included were prototypes and not the final versions. These amps had compatibility issues and were not delivering the brilliant tones that Craig designed."
 
BTW - I just ran Command Center again and this time it showed the Anderton update to bring it up to 1.0.0.8 so I guess it took a bit of time to get pushed with everyone hammering their system.

I just installed Sonar about 2 hours and 30 minutes ago. Mine already says build 254. I guess the first download I got was already the updated version?

Sure is!

If you didn't get the early release you automatically get the latest version and there is no further update.
