Hi, i think they will change it . I am in discussion with him .I like the new prototype case - I would buy one if the price + shipping isn't too high.
Yes, the line (frame) can be a bit nearer to the top and bottom edges to resolve the issue with proximity to 'Midi' led and 'Volume' knob markings.
I also agree with av about the 'Data' knob markings; I would make them the same as all potentiometer knobs, that is have seven dots. Yes, it is an encoder not a potentiometer, but it would just look more consistent. You might also consider renaming 'Data' as 'Patch / Edit', since the encoder is used for scrolling patches and editing patches.
All that aside, it's very exciting.
