Hi
I had audio drops and slow startup and missing notes on chords
I had Platinum and Professional loaded by cakewalk Command centre.
I thought why can't I drop Professional as I do not need it.
I got suspicious.
I then Uninstalled Sonar Pro and Platinum and registry values for the shell of the program ,not all the content,Vst's etc. I also had Sonar X3 buried In the registry and deleted that as per Instructions.
Somewhere on this site It tells you how to uninstall and put back a fresh install.
I did this and everything Is running 100%
Also check the Usb lead from the sound Interface to the computer as that can mess things up.
I also purchased a new usb lead £14 to be sure and now I am on Fire!!!
All the best
John
