Not having much of a technical mind, I hope this isn't a stupid question.

I have in the past tried using Cubase (free version that came with some hardware) but just don't get on with it, however, I did like the way some of the effects are visually presented, EQ in particular, where you can see the band of frequency and pull them up or down to create a visual wave or line graph of your settings. I've also seen similar in the professional studio in Pro Tools.

Are there any free plug-ins that do this that I can use with Power Tracks?

Cheers
