Melodyne 4. Any users?

[lesmac]

HI, has anyone upgraded to Melodyne 4?

Its a half price upgrade from what I have- Editor and I'm wondering whether to take the plunge before the April 30 deadline.

Main considerations for me are stability. I've had issues with melodyne crashing in Pro tools when disabling then re-enabling or re-instantiating in the session. It doesn't seem to like too much material to work with either.

I've seen them moaning over on Gearslutz about the upgrade not really having improvements in the vocals department but maybe some things just can't be improved on?

Thanks in advance for any comments.
