If you don't have time to read this whole review, you should at least know that I used Rax for 2 days and it crashed more than 25 times.

Rax has really good features, but it ruined my gig. I have to stress that this software ruined my gig. I have about 10 "library files" with various setups that threw errors at some point, became unstable, and didn't ever reopen. My setups were not complicated. One of them was just two DLS synths. None of these setups would open once I got on stage, even though my equipment was setup exactly how it had been during sound check and rehearsals. The worst thing is that Rax wouldn't even work if I created a new library with DLS synths, even after a restart. Yesterday was a horrible time. I don't suggest buying Rax until it is actually usable.
