[Rosegarden-user] Changing line colours in the Matrix view

[Jakub M. <ku...@gm...>]

Hello,

in my installation of Rosegarden, the "lines" that lie on the black keys of
piano are shown in grey. However, in the images I found on the Internet,
they are sometimes all white, sometimes only some are grey. How can I set up
the colours of those lines?

Regards

Jakub Marian
