Sony ACID Pro 7
Full user review
"Haven't got it mastered yet."
No real pros that I can tell so far.
Terrible user interface with pale pastel colors. Very difficult to setup and navigate.
I had to buy a new PC for totally unrelated reasons, re-installed the demo and have since been unable to get my midi keyboard to make a sound. I tried ASIO, Direct Sound, Wave-RT and other mechanisms without success. This is certainly not plug-and-play.

I still cannot stand looking at that ugly GUI with pale pastel's and fonts. I have been using other similar software that is much more intuitive and pretty for as good (or better) a price. If I ever get this working I will write a proper review.
