sure, but you can probably just load the System Data which includes the FC Layouts directly onto 12.05. you shouldn't need to roll completely back to 12.03.Q1: So then to be able to use 12.05 and have the FC-12 not be all blank white windows I need to roll everything back to 12.03 first, then reinstall my saved 12.03 presets and system files, then update to 12.05?
this is unknown, but probably not. because there is a bug, they may have to change things completely which would render the 12.04 data useless anyway.Q2: If I am on 12.04 will everything be ok with the FC-12 when 12.06 comes out, if I then update straight from 12.04 to 12.06?
if you don't use the Looper or Increment/Decrement functions on the FC, 12.04 will work fine for you unless other bugs exist that haven't been discovered. because 12.05 is released, those bugs probably won't be found, as they need to fix the 12.04 approach anyway.
i would suggest sticking with 12.05 and just loading your FC Layouts as described.
