Searching for a free hex editor with pattern highlighting

Hi guys,

I am searching the web for a hex editor for windows, which I can tweak to highlight (by me) defined bit/byte patterns.
Unfortunately without success, so does anybody know one which supports this? :slight_smile:

If it's unclear what i mean - something similar like in this "grammar parsing" of hexinator.
But instead by defining the patterns itself instead of the offset and length of fields. (due to a far different use-case than in case of well defined/structured files)

Thanks in advance for every helpful comment/thought :slight_smile:
