I’ve been looking for such a list before myself. Unfortunately, it seems like the names are hard coded inside the Cubase executable. It seems Steinberg don’t really push the generic remote, seeing as it stayed the same annoying way for many years now, while advancing remote control configuration for specific vendors (Mackie, EuCon, etc).
Not only that, but from my experience with the generic remote XMLs, there are functions that appear in one name in the pop-up when selecting in the GR editor and having a different name in the exported XML. Some even having a numeric tag instead of name. Also, not all configurable parameters appear in the generic remote editor, while they can still be configured via the XML - such as some of the EQ parameters.
I’d love if there was a real API you could interface with rather than going through annoying midi commands.
