If you don't have windows xp, I recommend using a MAC since Windows operating systems are constantly on the verge of crashing or getting completely outdated. MAC users can still use Graphic Equalizer Pro since the sound file that it uses is already format for use on MAC computers. However, it would be nice if there was a version of Graphic Equalizer Pro for windows that also converted to use on windows.
One way to get around this problem is by purchasing the Graphic Equalizer Pro software which also converts the sound files to use on windows. It would cost a bit more but it would be worth it in the long run as you will not have to keep buying the other upgrades for your mixer and other equipment. This software is available in the market and can be easily purchased from their website. If you want the older version of Graphic Equalizer Pro, you can always purchase it directly from the manufacturer's website but it is highly recommended that you go for the latest version since it has received much more attention and popularity after its release and is the most compatible software for both MAC and windows systems.
