Brian,
thanks for the reply, but I think there's a misunderstanding.
This is about a plug-in I'm developing. Just because its shipping doesn't mean we should stop development, and not improve the product :-)
I'm sure Logic supports the HUI, the question is rather this:
Can the plug-in map it's parametes, in order to decide which parameters are shown at which "positions" in the HUI (a "position" being a page and switch / rotary index).
If this is not clear, please let me know.
Thanks,
Michael Olsen
