I use it with Cubase6
It is very stable.
Big and clear GUI makes it easy to use.
It is Mouse-controllable.
Definitely not CPU-hungry.
Very efficient, and delivers an accurate sound.
Can't do without it on each and every track to normalize the signal (and boost it if/when necessary).
Overall, it's a great expander/limiter, full of features and easy to use.
Very quick learning time.
