I love the new visuals but the one change I would make would have to be the Casualty visual. I really like it however I think it needs to be more active, even the most dynamic sounding songs that really have punch don't seem to cause it to move much. It needs to have more kick to it more livelyness if you will.

The Casualty visual uses the RMS value of the left and right channels combined together to determine the amount of displacement. The scaling is carefully chosen so that the maximum possible RMS values will cause a displacement to the top of the screen.

If you are experiencing very low displacement on all your music you should check that it has been normalised.

Is it weighted by frequency? Tracks that have a regular but high pitched beat (such as with cymbals) do not register.

It works perfectly fine for me. It looks just like an patient's heart monitor (at a very poor hospital ).

This is just with normal, everyday music (I think I had something like Brad or Satchel playing. how many people here know who that is? )

I don't know if it is weighted but that is normal. There is more power in low frequencies so the lower ones tend to have that kind of effect. You'll see a similar thing on some of the other visuals.

I reckon it looks OK with some 80s rock beats.

OK I guess mine is working alright, I still like it don't get me wrong. I tried some different files and does make a difference.

But think about what you're saying. If there is more power in lower frequencies... which by itself is a true statement but does that make it correct? Consider a song that has a low level constant nonrhythmic rumble, and a high pitched beat. that will register as flatline in casualty. The rumble will barely register to the listener because the sharp silbilent sss....sss....sss....sss... beat is more sonically evident. It ends up that the visuals don't match what is perceived.

I'm inclined to disagree. I've seen songs that have a constant low rumble and the line stays off the bottom. Also, for resons I can't yet determine, when I listen to my aux (alpine) input and turn it off, It must close the inputs in some manner because the line goes to the top. I'll have to do more testing with this and see what is actually going on.
I believe the display is correct.

No, it is the RMS value. Lower frequencies have a higher power than high frequencies, and therefore cause more displacement.

What you're talking about is the difference between a technically correct visual and a psycho-acoustically correct visual. I do have plans to modify the visuals to be more psycho-acoustically correct than technically correct.

The effect you are seeing with the AUX in is the automatic gain control. When the signal becomes weaker, the gain is boosted. The line goes right to the top because it is using maximum gain and normalisation (There is some noise). This problem has been fixed for future releases - When the signal is below a certain threshold the gain and normalisation are reduced to zero.
