The problem isn't which functions can't be accessed. You can control plenty of the empeg functions with a stalk. Especially since you can use Hijack's IR Translate feature. But that still doesn't help you.

The REAL problem is seeing what you're doing on the screen. If you can't see the menu options you're selecting, you end up selecting blind and screwing up.

As I said here, if all you ever want to do is shuffle the whole player and hit next track and previous track, you can mount the empeg under the seat and use a stalk or IR repeater. But if you want to do anything more than that, you've gotta see the screen.
