I have this utility about six months now, and what I can tell is that it helped me build midi commands inside Cubase almost impossible in its normal way (generic remote).
Assign encoders to correctly move cursor, nudge parts, zoom in/out, select left/right locators, tap tempo (Yes! but this one is a bit complicated), create new track using selectable vsts, duplicate/cut/copy/paste, split/glue, and the list goes on (I have more than 40 'translators' until now).
This utility was a game changer for me, and brought my Komplete Kontrol MK2 and Arturia Keylab MK2 to a new level of integration with Cubase.
Warning: It has its learning curve, some things are easier than other, but the final result is excellent!
