No MIDI playback

[Joseph Wakeling]

Hello all,

I'm a complete novice user of audio software---I have some familiarity
with notation software like Finale and Sibelius but only on Windows
(though I'm familiar with Linux and Ubuntu in general).  I'm trying out
Ubuntu Studio simply as a way of learning about audio editing and so on.

I've been playing with Hydrogen (drum sequencer) and Rosegarden, but
have been unable to get any playback in either.  Rosegarden, for
example, will "play" but no sound emerges.  I suspect this is due to
MIDI being incorrectly set up on the system but I don't know what to do
about it.

If in Rosegarden I go to Settings -> Configure Rosegarden and click on
the Sequencer tab, the sequencer status is given as "MIDI OK, Audio OK".

As I'm totally unfamiliar with both the software and the Linux audio
environment, I'm at a loss to know what to do.  Can someone advise me?

Many thanks,
