Yep, but as they are not precisely about NRPN messages management (transmitted by endless knobs of a MIDI controller), I created my own one from tests done with the C12 trial version. So, I’m waiting, in it, for any advice from either users or Steinberg crew member… 
Beside this, I still would like to know if an unistall/reinstall process is needed if I take the plunge and purchase a ‘regular’ C12 licence, after having used the trial one, or just a licence update could suffice. The expiration date is next 30th september…
