It's the dinkiest little utility application too. Surely an intern could port it to Windows 7.
I played with the rumble noise some more. It seems to be worst in the left main rumble motor. That's the one that does the low frequency coarse rumble. The right side does finer rumble and I can't hear the whine when it vibrates unless I really pay attention. So I kept that side enabled. The effect isn't as nice because it's such a fast vibration that it kind of bothers my hands. I guess I should lower the intensity in the app. But I kept thinking about it more and realized I hate vibration in beat 'em ups, which is all I play these days anyway.
The other annoying thing about the Elite controller is the thumbstick snaps back to center so hard that it bounces past the center point slightly. Depending on the dead zone in a game, it sometimes registers as movement in the other direction. Strange. Maybe there's a way to tune it in hardware or software.
