This is just from menu but it should be roughly right
Scroll Speed - Menu > Mode > Scroll Speed
Then set it to 1x for smooth scrolling from left to right or horizontal for it to disappear and the rest to come on to the screen horizontally. Just try setting it to 1x first cos i think thats what you mean.
9 Band Visualisation – Menu > Display > Visualisation, then choose something like level meter 2
Hope that helps
