I use it with Cubase 6
GUI is large, clear and well readable
The plugin is mouse-controllable
It is not too CPU-hungry
It's really efficient and accurate
It is a multifunction processor including compressor, EQ, De-esser and Boom (Kick)
It brings a real improvement at the mastering stage
The bx_dyneq v2 is a complete dynamic equalizer and compressor.
It doesn't take much time to get used to using it.
