SoS added a bunch of flash patterns a year or two ago, but there's some confusion if the older bars can run the new patterns. SoS says they cannot, but mine did.
The bar doesn't have set flash patterns per se. You need to configure it via the software to flash how you want it to. The 8 modules are grouped in pairs with their respective counterpart. So the ends are grouped, the second in, third in, and the center two are grouped. Then you can choose a specific pattern/color(s)/phase for each group.
Unfortunately far as I know you cannot run different patterns within a group, so you can't have the end module on the left run roadrunner while the end module on the right runs intercycle.
SoS has a pattern demo on their website, but it doesn't work very well and isn't very telling. It shows you the pattern, but it doesn't show what can be accomplished with color/phase changes. That's the problem you're going to have, your bar has literally millions of possible configurations.
