The editing interface of the Kemper works really well for me, so I would not miss a full-featured editor.
CK used the term "Rig management software", not "editor". That sounds to me like it will be a Librarian (maybe tag editing will be an included feature, and MIDI program change assignment)
That's not the same thing as an editor for all the amp, cab, effects parameters in each Rig.
So, something like a Librarian will come at some point. From what I have read in this discussion thread, no official notification has been made that an Editor is coming.
I'm OK with that - I like the user interface on the Kemper. I find it to be intuitive, and very well thought-out.
I'm only mentioning the difference between Editor and Librarian because it sounds to me like other people have interpreted CK's sentence to say there is a plan for an Editor.
I don't want people to be disappointed with an Editor - I'm really looking forward to it.
