I'm not sure why , but after opening a song I was working on in Lexington in Manchester I had 2 crashes ...
Some sort of problem reporter came up and I said yeah send it ...that was it ...
I didn't give it much thought even though I lost a bunch of edits ....they weren't keepers anyway
Ever since that happened every thing else has been smooth .
I may need to learn the new features ...aside from that  ,I think Manchester seems to be a little more perkier than Lexington on the machine I upgraded ....

I did the Melodyne 4 upgrade. The Universal Algorithm is pretty sweet. Make sure you get the latest version, though.

I'm holding off, because I feel Essential 4 is a downgrade over Editor 2.  Maybe before the 4/30 deadline with Celemony, I'll upgrade, but don't feel the need for now.

I should have mentioned I have an unfair advantage...the version of SONAR on my laptop is "stock," so it had Melodyne Essential and went up to 4. My desktop is still running Editor 2. I do this so if I need to know exactly what someone is experiencing with "out of the box" SONAR, I can test it on the laptop. The desktop does the heavy lifting. This also allows testing in two different environments. However, I'll likely upgrade the desktop to 4 at some point.
