Description William Kenney 2013-04-16 17:58:49 CEST

I'm going to admit that I am not familiar at all with this package.
But, for a friend I am attempting to find a working midi sequencer
on Linux. Be that Linux Mageia, Mint or some other. It seems that
Rosegarden is the, or one of, the most popular midi sequencer programs.
So installing rosegarden-11.11.11-2.mga2.i586.rpm from the MCC
goes fine and the appropriate icon appears in the Sound & Video
launcher menu. The package opens but a pop-up window opens indicating
that "Jack" needs to be installed and running. jackit-1.9.8-3.mga2.i586.rpm
is installed in M2 by default and it is running. When I attempt to
create a simple one or two note midi sequence and play that rosegarden
seems to execute but no sound comes from the system. If I import a
( professionally ) previously created midi file ( .mid ) that works
but again attempting to play results in no sound. I put this question
to the Mageia discussion forum and one response was that as of around
Linux Kernel 2.4 or so this application stopped working. Prior to
that it worked "out of the box". Another comment was that I don't
have a "fancy sound card" in my system ( Intel N10/ICH 7 Family,
snd_hda_intel module ). Seems it outta work with that. The same
symptoms are encountered on M2 & M3. I have installed Qsynth and
DSSI as requested by rosegarden.

I have attempted to get this to work in Linux Mint and encountered the
same problems. I do not consider this to be a critical application
nor a release blocker on M3. But, I file this bug requesting info from
the maintainer and as a note for any complaints for future users.

CC'ing the maintainer, maybe he has an idea.

Maybe simpler to use qjackctl.
Install it, run it and start it before running rosegarden.

Hi William !
 Hi Barry (thanks to have added me to the CC list) ! 

I can say that Rosegarden is a very good sequencer ant that it works fine which ever kernel I use on Mageia 2 
OK with 3.3.8, with 3.2.16-0rt (realtime), and with the last updated kernels 3.4.34 and 3.4.34-0rt (realtime too)

Yes indeed Rosegarden needs jackit to be installed

But it's not necessary to use qjacktl (rosegarden itself can launch JACK : it's an option )

Nevertheless Rosegarden can't play Midi files if it's not linked to a MIDI instrument. (which can be selected inside Rosegarden configuration menus)...

There's a choice for what kind of MIDI to use :
- Some soundcards can use soundfonts and be such an internal physical MIDI instrument
- Some soundcards have a MIDI output which can lead an external MIDI instrument
- Some softwares (such as Timidity, linuxsampler) can be used as a vitual MIDI instrument.
- Some polyphonic synthesizer softwares such ZynAddSubFX can be driven by Rosegarden too

Inside Rosegarden Help menu some useful manuals can be read !

NB I personally don't use Pulseaudio, which brought some problems for me ...
I prefer to use alsa drivers and jack directly (old school configuration)
