No, the Special Abilities will work while the style is running (if the font is set up to support) as a regular style or Using function just fine. It’s just that you can’t use the Special Ability to make the preset different because it’s temporary, it will always start with Phase 0 active.
Typically, users would use a Using Function with an Option Style so one Using Function can be edited to look and act different for each preset. This uses editing functions (Arguments) so that each preset can be unique.
If you have a Using Function running a “Phase” change then each preset that uses the Using function will always ignite exactly the same (Phase 0) and while that style is active you can change the Phases but if you change presets or remove power it will revert to Phase 0. The only way to change that behavior is with the “Save Alt” combined with Multi-Phase (Special Ability), this will save the last Phase for that preset so the next time you go to the preset it will start at the last Phase instead of 0. So this can allow you set up a Using function for Multi-Phase Special Ability styles and then save the Phases on each preset, but you have to manually do that in each preset AND if you change the Phase on that preset, the next time you go into it, that last Phase will be what is active.
Whereas, Using Functions with Option Styles that include Style Arguments will always start with the set Option (see discussion on Config Helper Tool and Style Arguments here: ProffieOS Config Helper Tool v3.0 Introduction (OS7 Feature Support and Config Optimization)) until you change and save the argument in Edit Mode or ProffieOS Workbench.
If you have something specific you’re trying to accomplish I can direct you on which is the better approach. Essentially if you have a Using function with Phases, they are temporary for each preset but can still be used on multiple presets but all of the presets will start out exactly the same so no real “benefit” to having multiple presets with the same Phase change Using function (unless you use the Save Alt but that kinda undoes the ability to change the Phase during use unless you plan to change back each time before changing the preset or powering down). The real value of Using functions is with Style Arguments because each preset can be set up to be unique, so you get more unique presets with a single Using style.
But, yes you can set a Special Ability style as a Using function (assuming each preset and font is set up to support) but you’re not really getting much benefit as it’s just the same style in each preset to begin with.
