Please don't tell me I am going to have to open my unit myself.

in addition, why don't the arrow keys move more instantly, and why does the selection of programs take about a second to kick in when changing programs?   What will be of this when in a live setting and presets don't change upon engagement at a particular beat instant?  Is the 7600 delayed in switching like this too?

And finally – why does it sound like there is a filter engaged when setting everything to "thru"?  It says that is just a in routes straight to out…. but why the filtering ouf of the highs?

I will try to be patient here but this overall outcome and experience has headed in very disturbing directions considering the cost.
