Scrolling scores are the most common type of score created for the ScorePlayer, and most basic scrolling scores can be created without having to touch the advanced preferences window. That said, it does open up quite a few different options and these are described below.
The advanced preferences window for scrolling scores.
This allows you to create a longer scrolling score from a tiled set of images. These should all be exactly the same dimensions, and named using the format filename_1.jpg (or .png), filename_2.jpg, etc. If the tile set was previously discovered by the ScoreCreator when first choosing your image file, then these values should already be appropriately set. Additionally, if your source images aren't already split then there should be no real reason to go to the effort to manually split them for display on the iPad. The ScoreCreator will automatically do this for you if it detects that it is necessary.
These modes are named after two scores by Cat Hope, Juanita Neilsen and Liminum, for which they were developed. Both of these are extended scrolling scores where the entire score image is played forwards and then backwards after a middle section made up of random fragments (played either forwards or backwards) taken from the score. The difference between the two is the exact behaviour of the middle sections. In Juanita mode, the generated middle fragments are synched between all of the iPads, while in Liminum mode they are entirely independent. The fields in this section fine tune the behaviour of the middle section, and apply to both modes. Here is a brief outline of how they work.
Juanita Neilsen, by Cat Hope, showing the options used for it. These create a middle section that is a minute long, with fragments lasting between 3 and 6 seconds. (The entire score is 11 minutes so the first and last sections both last for 5 minutes.) As the minimum and maximum fragment speeds are both 2, every fragment will have the score running at twice the speed of the opening and closing sections. And there will be a two second pause between each fragment.
These two options both affect the behaviour of the playhead. Only one can actually be in effect, so if a playhead image is set then that takes precedence. As would be expected, changing the playhead colour simply changes the colour of the playhead as it appears in the ScorePlayer. Setting an image as the playhead loads the chosen image to be used in place of the standard line. The right edge of the image is placed at the position defined by the playhead offset. To avoid any scaling discrepancies between landscape and portrait mode, it is best to keep the height of the playhead image the same as the score image.

The next set of options relates to the creation of a vertical scrolling score. The first checkbox switches us into vertical scrolling mode, and the remaining options control the specific behaviour of that scroller. All of these choices will be reflected instantly in the preview window. The direction can be set so that the scroller either scrolls down from top to bottom or up from bottom to top, and the playhead will be positioned accordingly. By default, the image file to be used for a vertical scrolling score should be tall and narrow, appearing in the exact same orientation as it will appear in the ScorePlayer. By selecting the rotated source checkbox, you can instead create a vertical scrolling score by rotating a regular scrolling score, as shown in the image to the left. (The rotation will be in the opposite direction if the score is to be scrolled upwards. The left edge of the image always forms the start of the score.)

The name to be used for the additional preferences file contained within the score. The default value here is fine, and there is no real reason to change it. It can be named anything except for opus.xml, which is reserved for the main score preferences file.
