I've been using XCAS together with NRaas mods since almost forever. There will be a conflict on the allowed number of custom sliders allowed if you use XCAS together with MasterController (and if you have any custom sliders, if not then this doesn't apply) but that can be overcome with an XCAS tuning file. It is fine to use XCAS together with some other Core Mods (like ErrorTrap), but not AwesomeMod. It is part of her XCAS mod, which is a Core Mod.
