I don't have Jupiter but I feel the same about new CS80, SEM interfaces.
All of them have a decomposing brown-ish, beige, drab palette, and the font/legend is more fuzzy and hard to read than before, even with all the expanded real estate the legend is way too small and difficult to read. All the text items need to be rendered far sharper and clearer.
I think usability was low on the list of criteria with the GUI work - in fact I can see where several misunderstandings of what the controls do have led to many labelling mistakes.
The GUIs really need to be considered more in terms of usability and work flow, and less in terms of 'authentic'.
I ranted here about the CS80 UX
http://forum.arturia.com/index.php?topic=87544.msg130838#msg130838And the preset browsing font choice is very poor. Quite difficult to read. There is no coherent UX planning for this section, things hard to read, inconsistencies etc. Futura font is a big mistake for small, lengthy character strings as many of the letters are hard to distinguish.
But hey, they still sound great....
