I just finished the screen for control assignment:

As you can see, there’s a lot of popup menus to select! On the bottom of the screen, there is a preset menu, which allows setting all the controls at the same time. Currently, there is just one preset, which is made for Novation Nocturn. Nocturn has 8 knobs and 8 buttons, so the default configuration has lots of empty slots, as the buttons cannot be assigned to anything useful yet.

If you are not happy with the preset, you can freely configure each and every one of the 128 midi controllers.
