I'm reasonably sure you can do both of those things with Hijack. In fact, switching to the Tuner and Aux is built-in-- just hold down the knob (and keep it held down even through the hijack menu appearance). The second one, you might be able to do with an IR translation. If not, request it as a feature for Hijack (in the Programming forum, please).

Hijack is great because it gives us a tool to re-map buttons (both IR and front-panel) to do whatever we want. User-customization of the buttons, including macro programming, has been on the wish-list of many empeg users. Now it is a reality, thanks to Mark.

If you're "afraid" of Hijack, don't be. It's very easy to install. Just throw it at my logo editor.
