Yes, that is still the case. How it was handled in H9 config worked well for me. H90 can actually map any parameters to any CC per preset. So it would be great to have configurable CC mapping in Mastermind, however, assigning H90's default CC's to match what Mastermind has also works.
I'm trying to use Macro to assign algorithm specified parameter changes. For just a handful of parameters that should work. It would be more usable if the preset action section shows the macro's name in additional to its index number, though.
