visual distinction for empty patterns in SEQ page

[XORadmin]

A dedicated "empty" pattern would be nice if you want to make songs with structure, but I wonder how that would look when it comes to patterns of different lengths.

Yes, thats why i think it needs some further brainstorming. As patterns can have different length, so there must be different length placeholders.

I guess to choose a SHIFT+START behaviour might be the best solution so far. Don't forget that there are other things to come which make the whole live behaviour more hands on.
