If your after an EQ you can open up your mediaengine directory open winamp from within that directory, then right click the winamp icon that now sits in your taskbar it will give you options, you can use that EQ. You can even enlarge it so its easier to use by touch. (you also have to press "ON" on the EQ for it to have any effect on Mediaengine) Works Great for me.
