I love EQ7. I have had EQ since version 5 and tried to use it on my Mac with simulation software and it didn't work very well.
I then bought a PC, but I forgot the basics that I learned originally several years ago in a class. However, I am excited, because in January, I am going to Road 2 California and taking 5 classes from Barbara Vlack.
EQ now offers EQ University online (
