In Windows, the advanced mode is intended to be used with the Roland
drivers; disabling it should be necessary only when you're using it with
a system where these drivers are not installed.  Due to bugs in the
built-in Windows USB MIDI driver, MIDI is made available only in
advanced mode.

In theory, Linux should support advanced mode.

Which kernel are you using?  To other programs (i.e., aplay/arecord)
work?

If this is a driver problem, Jack2 will not work either.
