Well, I've never encountered this problem, so I didn't bother.

But what's very odd for about the last week or so, is that when I turn the
unit on, Scene 1 is very soft and Scene 2 has a very high level of reverb.
When I switch the voice bavk and forth the the + and - keys, the problem is
gone. I really don't have any explaination for this, but I don't like it
either. My AN1x is about two years old now.

I reset the AN1x to the factory defaults. The problem is now gone, but for
one or other reason I can't use AN1xEdit (or, as it seems, any MIDI program)
with the AN1x (and EX5) anymore. Receiving a patch results in the display
going black, or flickering very fast (it's hard to make out). Now I had most
of my patches saved at an earlier date, but I can't really use my PC with my
synths anymore. It looks like something is echoing all incoming MIDI traffic
to the out, and my synth don't like that.

So one problem is solved, only to introduce another. :)
