I want to install, copy, backup my OS and softwares on to different computers of my choice, when I do my hardware upgrades. Or having a working spare system in place, so when my main computer has a problem, I can fairly quickly get my work done without interruption. And I don't want to pay double, triple, quadruple the licensing fees, just because I have a few some older computers sitting around. Some people don't even bother to read EULA, nor care to understand those legal terms, but most of them don't even allow the OS, or applications to be copied on to a running (operarting) computer so that such softwares can be readily run. Worse than that, many proprietary applications have their own data format. Years down the road, when I need to read such data files, those apps may not be installable, or runnable on my latest computer(s), and the older computers or hard drives may have died long before that.

Once you have a low-latency kernel, check related configuration in: /etc/security.d/limits.conf , or /etc/security/limits.d/audio.conf Oops, I meant: /etc/security/limits.conf , or /etc/security/limits.d/audio.conf Mine had at least: @audio - rtprio 70 @audio - memlockunlimited @audio - nice -10 it means your userid, which start jackd, needs to belong to the groupid called audio. I think in Debian, the /etc/security/limits.d/audio.conf portion is done by the package manager when jackd2 is configured to use realtime priority. But you need to check the userid that starts up jackd belongs to the audio group. The command groups should list all the groupid's that the current user belongs to. This is the low-latency configuration portion of a pre-compiled low-latency kernel. You can check to see similar configuration done within the Musix liveCD environment. Again, once you understand all the numerous steps and things which need to be in placed, you can configure any Linux distro to do similar thing, but each distro may have done things slightly different. If any of those are out of placed, you may not get Linux MIDI to work, or may have numerous problems like no sound, latency (out of sync, long delayed note) issues, skipped notes...

a hold of Alsa audio already, and nothing else can connect, or output to Alsa audio. That's the problem of Alsa audio, it only allow one app to connect to it. You can try to stop the PulseAudio daemond, then starts qjackctl/jackd. Even then qjackctl may still not be able to run jackd by default, you may have to play around with various parameters within the qjackctl Setup window. Good luck.

But I am at a loss how I can tie all these pieces together to produce any sound. How to plug in any of these pieces? There are many Linux Distributions (a.k.a Distros) out there, a very few distros are customized for MIDI related music: Musix, Studio64, Ubuntu Studio... Those distributions should have all the apps above and should also have Rosegarden setup to run from the desktop menu. If you try most other Linux distros, chances are they are missing lots of setup applications and configurations. Lots and lots of info, too much to share in a couple of email messages. Chances are one would be wasting lots of time trying to figure things out without some working examples. Your best bet would be to try one of the above mentioned distributions, at least their LiveCD. Booting up from the LiveCD, and run the apps, then inspect the settings for each of those apps and how they are tied together. Those LiveCD should be the best way for self learning if one spend the time to look around. These are excellent working examples to learn from. The Union interface of Ubuntu 12.04 does not lend itself to do things as one would do in a KDE environment. I wonder if linux is getting so smart, that it tends to outsmart itself with the increased complexity. Michael McIntyre Tutorial is a great write up, but is not geared to modern hardware. It is based on KDE and I am lost how to apply it to my Union interface. I think you mean Unison, not Union? Or, perhaps I could be wrong, because I don't even touch *buntu stuff. With most major Linux distros, you can run KDE, GNOME, Unity, LXDE, Fluxbox, or any desktop environment. Just happens that the default desktop is chosen as one way to use Linux. There is no restriction if you want to use other desktop environment. So if one doesn't like Unity, install and run with a different desktop environment. Most people are just so afraid of trying other options, or choices, or afraid they may break the computer. Or they were conditioned by Apple, or Microsoft, or their cell phone and PDA that they don't dare to try anything else. Every application has its own interface defined by their developers. They will decide what they want to do. The desktop environments is just another application. So one should learn how to use each application and don't pretend all the apps are one and the same thing. If you think in Windows everything look the same, perhaps you should look at the different versions of Windows, every new version of recent releases, people have to learn a whole new way of doing thing, especially with the countless system settings. Such a waste of time. Stick with one way of doing thing and be productive instead of wasting lots of time tweaking with how things look every few months because things look old.

Re: [Rosegarden-user] Compiling V11.06 with Qt 4.5.3 Fails

michael.mcint...@rosegardenmusic.com wrote:
I had this working perfectly there for awhile, but at some
point I screwed
something up, and now Rosegarden will compile against 4.7,
but fails to link.
I never did sort that out, I'm afraid to say. Still,
I had it all working
once, and I'm sure the problem can be solved for less
effort than upgrading
your entire system.
A while back, I did have multiple versions of QT's on a machine. The only
thing it would work for me (either runtime, or development) is I have to run my
own shell command to setup the proper PATH, and LD_LIBRARY_PATH:
. /home/userid/bin/setEnvQT451.bash
or,
. /home/userid/bin/setEnvQT471.bash
Note the . at the start of the command, which will take effect in the current
command-shell (at least with Bash shell). I don't remember if QT_DIR, or QTDIR
was needed, so I set both.
The following example of /home/userid/bin/setEnvQT471.bash , I also have my
own, separate copy of QtCreator 2.0.1, :
#!/bin/bash -x
export QT_DIR=/home/userid/compile/qt-4.7.1
export QTDIR=/home/userid/compile/qt-4.7.1
export QMAKESPEC=${QTDIR}/mkspecs/linux-g++
PATH=/home/userid/compile/qt-4.7.1/bin:$PATH
LD_LIBRARY_PATH=/home/userid/compile/qt-4.7.1/lib:$LD_LIBRARY_PATH
PATH=/home/userid/compile/qt-creator-2.0.1/bin:$PATH
LD_LIBRARY_PATH=/home/userid/compile/qt-creator-2.0.1/lib:$LD_LIBRARY_PATH
export PATH=$PATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH
##
So after running
. /home/userid/bin/setEnvQT471.bash
from the command line, I keep that command line to launch
qtcreator
or my QT-runtime app, which works with the specific PATH, LD_LIBRARY_PATH I
need for that version of QT.
Similar usage could be done for multiple runtime environments (if I want to run
multiple versions of my own app separately).
Or you could just upgrade. Karmic is obsolete, and no
longer supported by
Ubuntu. You could probably upgrade it to LTS
relatively easily, being the
next step in line, and then you could build Rosegarden from
there without any
further ado.

Most folks keep only one copy of Linux installed on their system. Upgrading
would be a huge pain, and potentially be crippling for a few days (even 1-2
weeks) while configuring the new installation. The more important apps get
used first, and less important apps may not get used until a week or two later
and need time to tweak...
My way around that is to have a separate partition of about 20-30 GB of space
for each Linux installation (full install, not using separate /home mount
point). So each copy of some some Linux variation, or version could function
independently. This way, I can switch to my old installation when I needed
something done right away. In the mean time, I can take my time to tweak some
newly installed Linux distro, or version at my own pace, I can mount the other
installed Linux partitions as read-only so I can even compare configuration
files, like
/etc/security/limits.d/audio.conf
Of course, I keep data files in its own partition(s), and mount those
partitions from each Linux install (at boot time, or as needed).
I have used such setup when I need to try distro hopping, or when I want to
try a new version of my preferred distro. It helps me quite abit. Of course,
I have to be mindful of which partion has which Linux flavor and version.
Perhaps this kind of setup would help some folks out there. It doubles as my
instant backup if I messed up in one Linux partition, I can boot up to the
other Linux partition, which has all my apps already installed and configured.
May not be too practical for older laptops because of limited diskpace, but
works well if you can spare the disk space. Enjoy.

Re: [Rosegarden-user] Real-time Linux needed?
If I remember correctly, real-time schedule and high resolution stuff used to be separate code patched to the main-line Linux kernel. They were merged into the main Linux kernel around 2.6.30 (+/- a couple minor revisions, pardon my memory). Those real-time folks took a little time off for one or two minor releases, but then started to work on new real-time patches to the kernel again. For basic usage including audio and Midi, the standard kernel has all the code there already for most of us, no need to apply the current real-time patch. The only thing is there are various options including the 1000Hz clock frequency that Rosegarden checks for, they need to be enabled at compile time (of the kernel). If your default distribution doesn't enable the 1000Hz clock, you may ask around within your distribution circle/forum on how to get that, or how to compile your own. Even with the 1000Hz option enable, you may still need to add couple of lines in your one or two configuration files to allow a particular user-id to use it.
