when presets are created for DAWs / VSTs
they will assume certain midi mappings.
of course, you can download this preset and then proceed to midi learn all the controls from the E1.
but this is a bit time consuming.
I was reading this thread which points out that u-he allows you to save and recall midi learn settings as a file.
and thought, wow, wouldn’t it be useful if this file could be stored alongside the preset on the web app.
or perhaps just have a section where you can add an additional ‘link’
(if you are concerned with file sizes)
this could not only be used with text files, but also users could add demo/template daw projects, or (daw) instrument presets.
it be nice to have this in one place, rather than having to come to this forum to look for more details.
(of couse, if we allow a link, that link could refer to a forum post here 
)
