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.

Michael McIntyre > I don't know if there's a command (command-line tool) to convert/export .RG to .mid file . Although, within Rosegarden GUI, you can export midi tracks into a .mid file. One way to export a single (or a few) midi track is to copy your .RG file (it's always good to have a backup copy), then edit the new temporary file, delete all the tracks you don't want, then export to a .mid file. Another way is to export all the midi tracks/channels (I prefer those terms over "segments" which may be just a few musical bars/measures of a track/song) into a .mid file, then use some tools like midisplit.pl (a midi tool to split up each midi channel into its own file). I believe all midi files must have a tempo, if none is found, it is assumed to be 4/4 120 BPM tempo . There are other utilities like midi2text, miditext, midi2csv ... but they have their own quirks. Some midi file(s) may have problem with one of these, but no problems with the other utilities .

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).

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.

What I have is not a "sound card", simply an el-cheapo "class compliant" USB Midi Adapter that works fine under Linux, more specifically Debian Sid.

By the way, if you shop online (as I mentioned ebay.com), make sure you factor in the shipping and handling cost.

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.

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".

Perhaps the problems aren't "uncooperative application" but because of
"uncooperative distribution", or
"uncooperative setup/configuration", or
"uncooperative user" :-)
Most common Linux distros are not MIDI friendly. Getting Linux MIDI setup
involves many configuration steps, orders of apps to start, as well as "audio
connections", and "midi connections" properly in connected.
I don't use SUSE, nor KDE, nor GNOME for that mater. Different Linux distros
do things differently, so I can't tell you step-by-step how to do things under
SUSE, let alone some particular version of SUSE. Even with Debian, I use
Debian Unstable/Sid, which is a lot different than Debian Testing, or Debian
Stable.
I also read just enough to stay away as far as I can from PulseAudio.
especially with low-latency usage of MIDI. You can try to configure
"PulseAudio" daemon to not automatically start, as well as configure KDE to use
"Alsa" for audio. That's right, if the distribution won't uninstall it. just
tell it not to run PulseAudio. Although, you may have to reconfigure many apps
to use Jack, or Alsa, or default audio output.
Fastest way to see it all working on your particular computer is to download a
liveCD of one of these distro: Musix, Studio64, Dynebolic, "Ubuntu Studio" (not
"Ubuntu", or "Kubuntu"). Boot up with one of those liveCD to try it out, if
you like it, install it in a separate disk partition to have it run faster.
Once you see it running, you can inspect the configurations and settings to see
how they all fit together. The order of things I would look at are:
Get rid of PulseAudio (just my preference to use ALSA).
Get jackd/qjackctl running with low-latency configuration.
Get fluidsynth to start using "jack" audio output ("-a jack"), not Alsa
audio output ("-a alsa"). Make sure to connect fluidsynth audio output to jack
audio "system" input port. Or, use the "-j" option of fluidsynth to do this
automatically.
Optionally use "Alsa Midi through", by loading "snd_seq_midi" kernel module,
connect Alsa Midi output port "14:Midi through" to Alsa Midi input port of
"FLUID synth"
Use "aplaymidi -p 14 /path/to/some/midi-song.mid" to play via the "14:Midi
through".
Start Rosegarden, and connect rosegarden "Alsa midi" output port to
fluidsynth "Alsa midi" input port.
I know each of those step require quite a few things in place. Those thing may
change slightly from version to version of the kernel, and of each application.
So, most instructions out there are almost always outdated. But if you learn
and understand how they fit together, you can get it done in any Linux
distribution, given that you have the the proper kernel, as well as time to do
the full configuration.
Yes, you can install all of those liveCD's on the same hard drive, each in its
own separate logical disk partition, along with whatever else you are using
currently. That's the beauty of Linux, if you have the diskspace and know
enough not to mess up and wipe out your hard drive in the process.
If you are not comfortable and don't know yet what you are doing, I suggest you
use a spare computer, and a spare hard drive to learn, meanwhile unplug the
current hard drive from that computer so you don't accidentally wipe out your
data.
Personally, I recommend Musix liveCD because it use Debian, I learned much from
Musix LiveCD a full decade ago. Yes, I spent months and months trying to get
Linux MIDI to work until I tried Musix liveCD. Yes, after trying Musix liveCD,
it took me weeks, and months to fully understand how all the apps fit together
with jackd binding things together.
Don't try to use MIDI apps without jack in Linux, some of those older apps may
work directly with Alsa. But in the long run, you will more likely need
jackd/qjackctl.
Precompiled low-latency enabled kernel for Debian, with fairly up-to-date
kernel version is available in Debian-based distros like aptosid, sidux,
siduction.
Yeah, I know much of what are wrote are all "geek" for the Linux MIDI newbies.
But if you really want to get Linux MIDI to run, you have to learn it. I
already tell you where to start, hint: Musix liveCD. I'm not related, or
involved with the Musix liveCD folks, just learned alot, and much appreciated
their work in the early days. Good luck,
Jimmy

The problem may be that PulseAudio is already stared and grab 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.

Not the "MIDI" tab, the "ALSA" tab. Read my previous post again about the difference. Fluidsynth and Rosegarden do not use "Jack MIDI" (MIDI tab), they use "ALSA MIDI" (ALSA tab). Use the ALSA tab "Midi through" port, it should be: 14:Midi through connect from that (on the left list), to the FLUID synth on the right list of the ALSA tab. Start jackd, and fluidsynth, complete the connections, then give us the output of: aconnect -lio You should have the aplaymidi to work first, it is much simpler than rosegarden.

They are 2 separate things. I don't even do any MIDI configuration within Rosegarden, you can rename, or delete ~/.config/rosegardenmusic/Rosegarden.conf to reset rosegarden configuration to the default values. I use qjackctl "Connect" window to do the MIDI connection, or use aconnect from the command line.

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...

Now I use Fluxbox, with a few commands in the ~/.fluxbox/startup file to startup some apps, since it doesn't save session information. Again, I keep a few 20 GB partitions just so I can install separate versions of Linux on each, wiping out oldest partition for the latest distro release. It also help me recover configuration info from one of the other partitions during the first few weeks as I install the apps I want. Of course, I keep my data in yet other logical partitions, separate from those bootable partitions. The arrangement saved me lots of time, headache, and heartache along the way. I think most GUI applications are dumbing-down the users, keeping them ignorant of how the system should work. Various *buntu distros are also dumbing down the user knowlege base, trying to cater to the dumb-users of Windows and Macs. Perhaps I'll share my upgrade experience. Since I'm using Debian Sid/Unstable, the repository is almost always in state of constant change, and some apps may have dependencies issue while the repository is changing. Yeah, early on I have had a couple of problematic upgrades that left Xorg broken so everything was in text console mode. A day or two later, continue to try upgrade did clear everything, and that computer was again working. I have learned to do: apt-get update apt-get -d upgrade the "-d" option tell it to only download, but won't actually apply the upgrade. If there are packages missing, or have broken prerequisites, I would not continue, but keep try those to commands until all the packages get completely downloaded. Once that's done without problems, I would go ahead with apt-get upgrade With all the needed packages and all prerequisite packages are already downloaded, I only need to make sure the system partition has enough disk space for the upgrade before answering "yes" to apply the upgrade. I don't think I have much of a problem with Linux system upgrade since. Of course, different distros not using apt package manager may have similar options, you may want to look up such options. More often, I upgrade certain apps with apt-get -d install someapp if there's no problems, then continue with apt-get install someapp GUI apps and their convenience is one thing. But they are not that smart, in fact they dumb-down the user knowledge exposure of how and why things work within the system. The less they know, the more problems they will encounter. Generally speaking, the GUI app developers make too much assumption, without error checking, or disk space checking. Good luck.

I have seen enough to say that, sure, there is some changes. But most of them are the numerous companies trying to one-up each other with so claimed "innovation". Just happens those things are new code base with little testing, trying to claim "first to market". So the users are guinea pigs. The *buntu distros are also dumbing down the user experience the same way Windows, Macs, Cell phones are. They claim to make things simple for the users. I'd say they want to keep the users from knowing too much, and that there are other ways of doing things, not just what presented by the GUI. The software industry have had many server-centric, then PC-centric, now back to server-centric (cloud, web-apps...) They are just the companies to sell new softwares along with suport and service contracts... churning the market for new revenues. Abandoned softwares need support contracts, or migration cost of developing for the "newest trend today". Sure the cell phone and tablet with wireless capabilities add a little bit more to the flexibilities, but again, they are driven by large software companies's drumming up of new revenue sources. > In the meantime we are stuck with these painful > transitional > technologies, such as GNOME 3 and Ubuntu's Unity, which to > many people > seem like (and perhaps are) monstrosities.

No we don't have to stick with the new "default desktop" or default GUI the *buntu chose to use. You can install any other desktops and use that. You don't have to stick with the PulseAudio, you can disable it, or uninstall it. If that's too much work to fight the current within the distro, perhaps switch to a more customizable distro is less of a hassle in the long run. Just as many of us abandoned Windows because they have made it hell to back up and restore the OS to/from bare hard drive. And with the Knoppix liveCd of a dozen years or so ago, it's a whole new world of simpler data recovery, and installation of Linux. We can decide what we use, not what they try force us to use. The more we learn the underlying components that make up our system and tools available, the better we are to make the computer work the way we want. Not how they want us to do, their way. I have seen enough of the churning changes. Unity is only available on *buntu, because none of the other distros care about it at the moment. I will stick with what works and not be guinea pigs.

Well so-called true geeks are just people who believe they have seen enough to know that Linux/Unix can be customized however they want. They are not the know-it-all either. They spent long hours to learn how things are done and replicated those scripts and programs, learning from open-source code available to them. I simply say that the "geeks" are just determined to get it done be cause they it can be done. Pseuodo geeks are either newbies, or wannabe's who haven't spent time to learn how things work, or are afraid of spending time to learn. Most people who have spent time to learn how to get jackd/qjackctl, fluidsynth/qsynth, rosegarden, MIDI working on a low-latency Linux kernel is a Linux MIDI geek already. Perhaps not a Linux sys-admin geek, or Bash script geek, Perl geek, Python geek... It's just a matter of how much one re

Distro hopping are like fashion followers, there are always new hats, new ties, new eye glasses, new dresses, new shoes, new cell phones... But of course, for newbies who haven't chosen a Linux distro yet, some recommendations are not such a bad idea, either, especially the newbies in the Linux MIDI arena. My use of Linux and Open Source apps are because I simply don't want to agree to draconian terms of the EULA (End User's License Agreements), and having to jump through all the hoops to back up and restore my computer, and associated applications. 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. With most Open Source softwares, the data file format can be read and data be extracted or converted much more readily.

Sure there are always things that make economical sense. Too bad, I ran into too many woo's and wow's of the "self proclaim ads", and "fake reviews" about software applications, and OS's. All B.S.!!! Software and even some hardware patents are now economic weapons. Same as patents used in pharma industry, and genetically modified seeds in farming. Talking about economic sense, economic development strategies are a a big farce, too. The burst of the dot-com bubble cause economy to slow down, so they lowered interest rates to encourage borrowing, leading to real-estate bubble, so they fake a recovery with trillions of dollars propping up the failed banks. Mean while the people are facing horrendous fees and interest rates by credit cards, being entices into buying on credits. Spend, spend money you don't have to help propping up the economy. Look at what Oracle was trying to do with various Open Source projects after they took over Sun. They tried to butcher, or screw up those projects big time. Many software companies have done similar things to try to snuff out the competition including buying out competing products, or companies and then shelved those projects or products. I don't care to deal with those people. That's why I prefer Open Source, forking is always a viable option here, not so for proprietary software.

So what are you objects to which Open Source license(s)? There are quite a few, but mainly only two major classes of Open Source licenses. As an "end user", there's very little or virtually no restriction. As a developer, or modifier of software, sure there are legal terms to those licenses, mostly to prevent unscrupulous people. Many people try to take Open Source software, and try to claim it's their own work. Those are the people who object to Open Source licenses. I have no problems with making changes to Open Source software and give back those changes to the Open Source community. I have read and understand the many Open Source licenses and have no problem with them. I do notice and observe those licenses. I see them as reasonable terms for my usage. I prefer those terms over restrictions in commercial software licenses any day. If you don't like it you don't have to use it.

Can you double check the output for a couple of command? Here's mine:

CONFIG_HZ_1000=y
CONFIG_HZ=1000
cat /proc/sys/dev/hpet/max-user-freq

If /proc/sys/dev/hpet/max-user-freq is less than 1000, you may want to try:
sudo echo 1024 > /proc/sys/dev/hpet/max-user-freq ; cat
/proc/sys/dev/hpet/max-user-freq
My kernel has
CONFIG_HZ_1000=y
CONFIG_HZ=1000
compiled in, but by default, it shows /proc/sys/dev/hpet/max-user-freq value of
64 . I have to set it within /etc/rc.local so it is set again everytime the
system starts up.
