Do you have any MIDI devices that Rosegarden is using? You won't get
any sounds otherwise.

I have following this steps :
http://www.linuxquestions.org/questions/linuxquestions.org-member-success-stories-23/setting-up-rosegarden-for-midi-music-in-linux-ubuntu-8.04-697198/

I add the .fs2 file in the qsynth, start jack, and qsynth, then start
the rosegarden in a terminal.
In rosegarden i go to studio/manage devices then select "128:0 Synth" or
something kind of.

I try two ways edit some notes in score, change the device in 'track
params' and select some instruments.
But i can not hear some sound.
Then i try open some .mid file , but no sound.

I receive this message when start. http://imagebin.ca/view/SLUeC9_f.html 
:/ i install all rosegarden packagens im my system:

urpmq -Ya rosegarden
rosegarden
rosegarden-debug
rosegarden4-debug

Some suggestion , i acceppt.

Att,

I thin the only step you're missing now is thay to hear something you
have to be sure that Rosegarden MIDI is 'talking' to Qsynth. To do this:
In qjack control open the connections window and check the ALSA tab. You
should see rosegarden with all the midi out devices on the left and
qsynth with the synth you started on the on the right.

Try connecting the 'Generl Midi' device to Qsynth.

Then set the device for your track in Rosegarden to general midi and play

Also check that Qsynth *AUDIO* autput is connected to the system output
(usually system).

Qsynth also has a midi onitor (can't remember the name) that will show
if it is receiving midi data

Sorry I'm not on my linux right now so something may not be 100% correct
anyway good luck.

Kind regards,
Lorenzo.

I have try but without success.

For constat is start jack with
jackd -dalsa -r44100

The Qjactl

The Qsynth with fluid

And the rosegarden ( so cute :)
In the Qsynth i connect now the General Midi (left column)with the
Qsynth Fluid(right column)


Look my screenshot i think this is correct:
http://imagebin.ca/view/yV2LlrEt.html

I think i jump some step, look the qjack control , in the midi tab is empty:

http://imagebin.ca/view/rFgsgLl.html


I still without no sound.

In Rosegarden, select a MidiTrack then.
On the left side in the Panel "Track Parameters" choose a playback device
( In the screenshot you provided, it would be called "out 1 - General Midi" )

On the same track create a new segment, enter some notes, start playback.

Check if your speakers are on. Make sure that the alsa mixer is not muted.
In the command line execute "alsamixer" for mixer controls.
Press M to mute/unmute, cursor keys to select, ESC to exit.

Some more tutorials etc. here:

Thank you for trying RG.

Hi!

There is show stopper in many distributions called PulseAudio.
You may get very strange behaivior of all soud sub-system with this beast, so my solution is to remove
pulseaudio and reboot. Then try again with jackd and RG.

In Ubuntu it is quite easy, type as root
"aptitude purge pulseaudio".
In Fedora you may try "yum remove pulseaudio" but I'm not sure it will not delete all dependancies so you should use rpm to get rid of
PulseAudio.

Guys,


REALLY tnx for all help.
I appreciate your carism, for the patient with me.
I discovery the reason for no sound !
It's called P.U.L.S.E.A.U.D.I.O. (urgh)
I stop the pulseaudio, and use only alsa.

Now, yes , rosegarden put out notes in my hear =)

I will try look a good synth to play a good sound.

My objective in use Rosegarden is learn music, trying compose with music
score and export to midi.

Tanks

[Hugs for all]

[GARY SEVIOUR]

I've just started using Arch linux for my music computer, one advantage of configuring the sound system yourself is you dont have to uninstall pulsaudio. <1ms on a good machine (I've got down to .333 ms for just hooking up a keyboard to midi output). I was actually nervous about using Arch and it took me a while to get my desktop PC working properly. Once you have followed the steps to get you graphics and sound working, further installations are a breeze.

I have been plagued with pulseaudio not working in ubuntu and fedora (what is PA actually supposed to do? allow you to hear sound from more than one application at the same time? I seem to be able to do that already).

btw I still recommend Ubuntu to new users and it has served me very well in the past and saves a lot of hastle for most everyday things (playing and coping music from a cd, connecting a printer etc without having to do loads of configuration).

I have always struggled with configuring rosegarden and jack.
On the jack side of thing it can be quite difficult to get it to select the correct sound card due to the numbering system used. If I start my music computer with my PadKontrol switched on my audiophile 24/94 would be accessed through hw:2 instead of hw:0 (this was while running 64studio, with arch I do not have the problem). If the sound card enumeration was an issue I suspect I could fix it by folowing the instructions http://wiki.archlinux.org/index.php/ALSA following on from "Setting the default soundcard".

One thing that gives me grief with rosegarden is that it makes many jack connections automatically (hw:1 and other device numbers point to different devices depending on the order that they are powered up) and I find hooking up various audio and midi connections in qjackctl to be a complete pain and is very fiddly and error prone. Because of the faulty gui, sometimes you are left with no option but to "disconnect all" and start again.Alsa patch bay may help a little but is still a bit painful to use. I hope in the future to delve into the problem and come up with a purely scripted (possibly it will have a gui option in the future) solution, quite possibly avoiding qjackctl altogether.

I'm going to have ago with pyjack, i suspect there is a way of configuring jack and making connections from the command line, but I have been unable to find the documentation on how to do this. What I would like to do is have a nice bash script to launch all my music apps (rosegarden, hydrogen, linuxsampler and possibly timidity) and make the relevent connections so that the metronome will always work and a piano will always be a piano etc.

Any comments guys?

Many thanks,
Gary

The Open Octave people have done scripts along these lines - I see they now
have a page for them:
http://www.openoctave.org/downloads/ooscripts
You might try downloading those and experimenting with them.

IMO Ubuntu has well improved the linux experience for "usual users"
and still does.
For serious audio work (realtime, low latency), it's not usable
without weighty modifications though.
(Use a dedicated audio distribution then)

> I have always struggled with configuring rosegarden and jack.
>
With qjackctl, there are only two real options:
a. use realtime or not
b. how many frames-per-period (with rt ~256, without rt ~4096)

The problem likely are the 3 different error sources, the setup can have,
which are hard to see through by new users:
1. sound hardware and drivers (alsa stage)
             make sure this is working first by testing with a
             simple audio player "alsaplayer -o alsa "
             (killall sound servers/daemons first: "killall artsd &&
killall esd && killall pulseaudio" )
             (use alsamixer to unmute your soundcard and set the volume level)
2. jack server (jack stage)
             make sure jackd starts properly (without errors) and
doesn't produce many xruns
             test jack setup with a simple jack-capable audio player
"alsaplayer -o jack -r "

3. (application stage)
             If 1 and 2 did not fail, continue to start a reliable
             soft-synth (zynaddsubfx (current release called yoshimi))
             start rosegarden and connect everything.
             Doing this is still somehow complicated, I agree. And
hard to describe in words.
             Here is a tutorial:

Agreed. It's cumbersome to dig in the config.files to set this up (but
possible at least)
(on debian/ubuntu one can change options in /etc/modprobe.d/alsa-base.conf)

>

This is (hopefully) addressed in the next RG release, wich will
provide a new device manager.

Habitually, I use the same channel for often used instruments
and save the setup of a project with each involved applications under
the same name (but with different extension)

Sorry. I wrote this cynical phrase due to the astonishing amount of
audio servers/-systems
that have been written for linux. There surely are estimable reasons.

Don't worry about it, Emanuel.  You're allowed to be cynical.  Sound on Linux
is freakishly complicated, and I'm long past being tired of dealing with it.  
The only thing worse than dealing with it as a user is dealing with it as a
support topic.

Bah humbug, humbug I say.

I found through a posting on LAU or LAD mailing list that this is no
longer required.  You can specify (in qjackctl for me) the device name
as found with cat /proc/asound/cards (the names I used are the ones in
[])

Instead of hw:1 & hw:2,  I use hw:H4 and hw:Intel which as long as the
names show up differently in alsa works great.

This works for me, but I am using a very current version of JACK, but
its worth a try.

I know that people often find this is the easiest way for them, but
really you shouldn't need to remove PulseAudio.  If you use qjackctl
to start the JACK server, then it should suspend PulseAudio when it
begins, and resume it again when it closes.  Provided you have a
recent enough version of qjackctl.

I happen to think that PulseAudio is a good thing on Linux, and it's
not impossible that future versions of Rosegarden might be able to
play through it as well as through JACK.

In my real world, Rosegarden is only one of the things I want to keep happy.  
JACK seems to play with PulseAudio well enough, but overall it's more of a
problem for me than a solution to anything, and the best way to deal with it
is to make it go away.

As I understand it, your idea for this is that we could use PulseAudio in
playback only mode as some out of the box way to make noise, which would be
better than nothing.

I spent some time really thinking about this whole problem, and I don't think
it's much better than anything else as a solution to the real underlying
trouble here.  The issue is that there is nothing any individual Linux
application can ever do to ensure that it's going to be able to make noise,
because there is no standard infrastructure to take advantage of.  We all have
to ask people to install and configure this or that, or run a distro that has
this or that installed and configured, or else we have to be the distro, the
way STG was.

It's complete madness, really.  Windows is a crap platform in so many ways,
but I expect if we put Rosegarden on Windows, Joe User can start it, load
"Bogus Surf Jam" hit play, and HEAR SOMETHING!

PulseAudio doesn't guarantee that.  First, they have to be running it, and it
has to be set up correctly, and their mixer has to be turned up, and so on and
so forth down the endless line of hoops every user has to jump through on this
platform.

Linux is the most complicated audio platform ever.  Hell, I had far fewer
problems hearing sound while composing music on my TRS-80 Color Computer, and
unlike the more popular C64 of the era, it didn't even have any dedicated
sound-production hardware.

I don't know about that.  I keep PulseAudio around on all my Linux
boxes because it makes my Flash video work in my browser at the same
time as I listen to music in my music player, and when I want to use
JACK, it just suspends while I do that.  Most of the things I do right
now work better with PulseAudio.  Wouldn't be so much of an issue with
different (better?) audio drivers or different (better?) audio
hardware, but that's the way it is.

If the only applications I ever used were JACK-capable, I wouldn't
want it.  But given that I'm not a studio and I use a web browser more
than most things, I want a nice desktop audio API that works.

Yes.  The problem is that "it doesn't make any sound".  If it made
some sound, but warned you that the sound might not be the best thing
ever and told you how to improve it, that would be pretty neat.

Hm, well I don't know about you but it's been a while since I've used
an Ubuntu install that didn't (for example) play the startup noise
when you first logged in.  That generally seems to work for me these
days without any troubles, and that's through PulseAudio.

> Linux is the most complicated audio platform ever.

No particular argument there.  Still, even applications using ASIO on
Windows have to assume a certain amount of friendly intent on the part
of the user.  They don't just get low-latency audio provided for them
for free.  What they get is pretty similar to using Pulse by default
and JACK for the advanced user.

It's really horses for courses isn't it.

I use 64studio (3 beta) on a dedicated music machine where I very
specifically want jack, and no other messing with sound at all. For
me, any system sounds, effects etc. along with pulse are straight in the
bit bucket. And yes, I did notice occasional strange things until I
removed it.

However, I have a relatively cheap 'domestic' machine that runs
debian/squeeze for which I allow any old crap to run, and for that one
pulse has it's uses.

Ironically enough, PulseAudio seems to be the culprit preventing flash video
from working here.  I just went through all of this yesterday, logging out and
rebooting for the first time in months, and I had forgotten how I fixed this
problem last time.  Dumping PulseAudio really seemed to be the key.

I got the startup sound, sure enough, but no video, and by no video I mean the
flash plugin would display one frame of the video and sit there for eternity
waiting on some audio sync signal (presumably, since there was no audible
sound) it wasn't receiving.  I could advance it to a new frame, and it would
sit there stuck again.  MPlayer fared better, but the video wasn't playing at
a constant speed.  It would drag, drag, drag, and then jam through a bunch of
frames way too fast, then drag some more.

Getting rid of PulseAudio was a real relief, and none of this had anything to
do with JACK one way or the other.

Me too.  You and I are alike in that we don't really want to have to have a
devoted audio box, no matter how much the real hardcore people will scream
obscenities at us for not having a totally dedicated stripped down audio box
that never does anything else.

It's just that from where I'm sitting, PulseAudio isn't that API that works.  
It's just another brick in the wall.

I agree, although even having an audio server to depend on wouldn't solve the
underlying problem.  Using PulseAudio isn't going to get Bogus Surf Jam
playing in of itself.

So we support PulseAudio for default sound out of the box, how is that going
to make Bogus Surf Jam play?

In of itself, it won't.  We'd have to hack the file itself to switch it over
to use DSSI plugins.  We'd have to hack all the example files and the factory
autoload too.

I really don't like that idea.  It would be far better to be able to provide
something that could stand in for "General MIDI Device" straight up in the
conventional scheme of things.  Plugins just have a crappy interface all the
way around.

I suppose one possible answer to that is to ship with an external DSSI host
that could speak PulseAudio.  That way we could route everything to it very
easily in the conventional way, and users could avoid dealing with the
horrible plugin interface.  (Want to change the soundfont?  Use the Editor>
button 15 times and navigate through 15 GTK+ file dialogs.  Welcome to state
of the art my friend.  What was that?  The sound of derisive laughter before
you ran back to Windows?  Oops.)

Yeah, I have to agree with you Micheal. Dumping Pulseaudio helps with a
lot of audio problems.

I don't think pulseaudio belongs in a professional audio setup at all.
It may be good for gamers and casual music listeners.
