Real time for Ubuntu Studio 10.04 amd64
Hi :) I'm new to the list. Regarding to hw MIDI jitter, I'm testing and comparing several Linux setups. Here is a rough summary of my latest thread on LAD. I wonder what I need to do, to get a kernel-rt for Ubuntustudio 10.04? Ubuntu Studio 10.04 amd64 $ uname -a Linux ubuntu 2.6.32-23-preempt #37-Ubuntu SMP PREEMPT Fri Jun 11 10:19:07 UTC 2010 x86_64 GNU/Linux $ alsa-midi-latency-test -Rrw=2 -o20:0 -i20:0 alsa-midi-latency-test 0.0.3 set_realtime_priority(SCHED_FIFO, 99).. done. clock resolution: 0.1 s SUCCESS best latency was 1.00 ms worst latency was 3.36 ms, which is great. 3.36 ms isn't great, but unusable to make music. openSUSE 11.2 amd64 uname -a Linux suse11-2 2.6.31.6-rt19 #1 SMP PREEMPT RT Wed Nov 18 16:59:26 CET 2009 x86_64 x86_64 x86_64 GNU/Linux alsa-midi-latency-test -Rrw=2 -o16:0 -i16:0 alsa-midi-latency-test 0.0.3 set_realtime_priority(SCHED_FIFO, 99).. done. clock resolution: 0.1 s SUCCESS best latency was 0.99 ms worst latency was 1.05 ms, which is great.

PulseAudio
A last newbie posting. I surfed the devel mailing list archive. https://lists.ubuntu.com/archives/ubuntu-studio-devel/2010-February/002220.html For 64 Studio (AFAIK it's the only audio distro beside Ubuntu Studio, that is based on a .deb system and supports amd64 architecture, but only i386), PulseAudio is disabled. It's making things much easier for users. OT: To have the choice between JACK1 and JACK2 would be good to, AFAIK there's no distro supporting this. - Ralf -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users

I just wonder a little bit, because for an audio distro there might be some hacks, that are different from an averaged desktop distro. IMO mixing tickets for desktop computers and audio studio computers could lead away from the target to get a stable audio and video production Linux, because 'democracy' does mean to fit to the needs of the most people, but just a minority group needs real time audio. - Ralf -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users

I have such message too but it is not stops booting and not affects my work. I have no idea what is this exactly :) This message will pop up, and the cursor will blink for some time, but the computer should start up if you wait long enough. At least, this is how my computer works with the current -rt kernel. I don't know what the actual message means, though. Aha, it might be some of that esoteric issues :D. For my self build kernel 2.6.31.6-rt19 on Suse 11.2 I need to wait around 10 seconds when GDM appeared, I also could log in, but than the screen will freeze and I need to push Ctrl + alt + double-backspace yes, I need to push backspace two times and log in (again), then everything is ok. - Ralf -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
No audio - was: Real time for Ubuntu Studio 10.04 amd64
Hi :) today I tried Ubuntu Studio again, but I had no time to work on the realtime kernel issue, because I got some new issues. 1. After updating apps and the non-realtime kernel, my manually edited grub.cfg was automatically overwritten by a completely grotesque grub.cfg, without an automatically backup of the original. So tomorrow I'll have to do a hard job to make all my really existing kernels and Linuxes bootable again and those who are already bootable needs to get rid of those annoying boot splashes, unfortunately I didn't backup it myself. 2. I tried to play a MP3 by Movie Player, the PA setting meters show output, optional for one or the other of my two Terratec EWX 24/96 sound cards, but there was no sound hearable or visible for Envy24 control. 3. I installed KMPlayer, set it up to use JACK, run JACK, launched KMPLayer, pushed play and play stand still. Any hints how to solve issue 2 and 3 are welcome. Cheers!

Rather than editing /boot/grub/grub.cfg directly you need to edit or replace the files in /etc/grub.d and then call update-grub. The scripts in /etc/grub.d are executed in order, hence the filenames beginning with numbers, so if you want to add custom entries at the top call your file 08_localstuff or something. I've blogged about this in relation to realtime kernels [1]. Perhaps you can modify that to suit your needs. If you just want to include some static text in grub.cfg you could create a file like this (and make it executable): #!/bin/sh echo EOF your stuff for grub.cfg goes here EOF Hope this is at least a little helpful ⢁) [1] http://funkyhat.org/2010/01/19/putting-rt-kernels-first-in-grub2/ -- Matt Wheeler m...@funkyhat.org Thank you Matt :) 1. My fault not to backup grub.cfg or to switch to GRUB 1, resp. not to use GRUB 1 of my older Linux installs. 2. For the future I could backup grub.cfg or I should (have) read about GRUB 2 myself. So, okay, GRUB isn't that important, OTOH thank you for making it easier for me to keep the new GRUB. Anyway, I still wounder why GRUB does search for outdated GRUB 1 menu.lst's ;). Not the hint I was asking for, but OTOH a really good hint, because the new GRUB for sure will remove the old faithful GRUB.

On my stationary machine it finds all hard-drives, partitions, oses and every single Linux kernel. You'll just have to edit /etc/default/grub for your needs on the Linux from where you updated grub i.e. for getting rid of splash and recovery mode, setting defaults etc.. I also have an ice1712 card, a hoontech dsp24, and it worked ootb in 10.04 64bit. But just in the moment I have problems with sound/alsa in kernels 2.6.32.23 and 24 generic and preempt. With rt kernel 2.6.33.26-rt and jack2 (available i.e. in falktx ppas) and alsa updated to 1.0.23 all audio is fine. Even if both your cards are selectable in PA I think your problem has to do with multiple sound-card setup which seems to be not trivial in Ubuntu. Can you select them in Qjackctl too? good luck Gerhard Yes, I'm able to select them by Qjackctl too. I didn't make both cards a single virtual card until now. I can't boot any kernel-rt. There at least is an issue for X. I'm unable to start GDM. There's no sound for the preempt kernels. Because there isn't a xorg.conf anymore I'm unable to switch between drivers for the graphics ... right now I see there's a xorg.conf.failsafe using the vesa driver.

Also have some network timeouts from time to time... As you say, this is a problem of all the things work together (the motherboard, bios version and linux rt version must match), this is why I was looking for a MB with integrated graphics that was known for working with the current Linux RT kernel ... That way the only difference I will have is the audio interface (I'm using a Tascam 122 usb sound module). Buying a third motherboard to see it doesn't work with ubuntu studio will be to much - specially to justify it to my wife :-) Im looking to ASUS because they have good motherboards and normally they have frequent bios updates (this should also be true for MSI, but unfortunatly not with the one I'm using). The BIOS of my current MSI boards misses many setup options and features. Fernando Hahaha :D I do understand your wife :). Hm, if you should have children, than you could argue with 'Linux should become more popular, because it's FLOSS, so knowledge is forwarded for free and to everybody'. Of course a week argument, if the costs for the gym shoe needed by the children for school vs a new mobo for you. There are hardware black/white/grey lists, e.g. http://www.64studio.com/node/69 ... but again, I don't trust those lists, they are ok for on Linux distro's version, but not ok in general. On then 64 Studio users mailing list some people said that Linux + MSI hardware should be the best combination, while e.g. some news on German say that Linux is a PITA, http://www.pro-linux.de/news/1/13293/rueckgabequote-bei-msi-linux-geraeten-hoeher.html for most consumers, e.g. when using MSI-Linux-Netbooks. The valid argument of the consumers is, that they don't like to learn, but they wish to have a tool working out of the box. IMO 'out of the box' for realtime audio using Linux is utopistic. It's possible if you've good luck, or if you are a bad musician, engineer unable to notice the week points. For some reasons we decided to use Linux for making music, so I guess we need to offer much more time as we would like to offer regarding to hardware issues etc.. I'm just a user. I guess if you describe your hardware and your issues more detailed some coders would be able to help you efficient.

Oh, I was not using MIDI up to now, so please be patient when I do not understand something at once :) E.g. make a song with Hydrogen playing nothing for e.g. 10 bars and then let Hydrogen play the needed patterns, sync should be done by JACK transport.

Re: Start 2 functions of apps at same point of time
Hm? It shouldn't be a pain, but just be annoying to change recorded drums later ;). You could record drums and later mute those drums and record or just play in sync new drums. I don't know if there is a sync issue for JACK transport now, but once there was an issue. There was a delay of one buffer size, that caused a delay that sounds similar to an early reflection effect, but even if there should be such a delay, I guess you could give Ardour's tracks an offset. I did run Rosegarden or Qtractor to play drums by Fluidsynth DSSI, or Qsynth for Soundfonts or LinuxSampler for GIG files or I used Hydrogen without it's own sequencer, but as a MIDI sample player. Unfortunately PC realtime (Windows and Linux) isn't ok when using external MIDI instruments, because of jitter, internal a PC (Windows and Linux) MIDI is without jitter. Avoid USB MIDI and prefer gameport MIDI regarding to issues caused because of jitter. A picture of the Delta 66, http://www.m-audioshop.nl/images/delta6p2.jpg, shows that it comes with a gameport, perhaps it does support MIDI, you just need a cable including opto-couplers. For the 1010 there seems to be a MIDI adaptor part of the product contents, http://bavasmusic.com.au/store/images/delta_1010_lt.jpg. If you are from Germany get this adapter http://cgi.ebay.de/Midikabel-IN-OUT-THRU-Gameport-Verl-3070-/300452789949, if not use the search engine and search for something that doesn't cost too much. -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users

I wonder what will happen, if I make my 2 Terratec EWX 24/96 cards 1 virtual

I tested analog stereo for KMPLayer set up to use PA and the sound preferences
were set up to analog stereo output and simultaneous output for both cards,
while I just tested one of the cards, but the sound was ok :).
Anyway, before this test Movie Player crashed and there are issues for the
website of a friend, http://achimjaroschek.com/music.html, while sound was ok
for his YouTube channel, e.g. http://www.youtube.com/watch?v=Mu6uFtCASYc.
This does the trick:

Unfortunately there are still many issues and today there are some new issues.
I don't have those issues with 64 Studio 3.0 beta (Hardy) and 3.3 alpha

I'm still in a production with recordings Achim and I made, so there's no time
to fix Ubuntu Studio right now. I'm doing the production using 64 Studio 3.3
alpha and even if the software works without issues, it's still tricky and time
consuming and there always is the risk of a crash, so I can't use Linux for
recording Achim and friends or other serious musicians who are short in time,
only if there's a lot of time, it can be used for post processing. IMO for
Ubuntu Studio it would help to remove desktop stuff like PA from the distro.
This and next month Achim does some concerts in Germany,
http://achimjaroschek.com/, certainly I'll be at the concerts in the Ruhrgebiet.
The next 6 month I'll do a job with elementary school kids, but professional
musicians, it might be that Linux could be more interesting then.
2. Does anybody know how to add libflashsupport-jack? Compiling and

See: http://www.mail-archive.com/ubuntustudio-test...@lists.launchpad.net/msg00351.html I had the same issue with Suse 11.2 and I could solve it by adding those two lines for Suse 11.2 too. @ Pablo: Thank you, thank you, thank you Pablo :) @ anybody who is pro PA: PA for rt audio users is a PITA. It might have advantages for the averaged desktop user, but we should get rid of it for rt audio distros. As I told before, until now I prefer 64 Studio, it's based on Ubuntu, but ships without PA by default, hence using flashplayer without JACK support and JACK at the same time is no problem. While Suse isn't important for me, Ubuntu Studio is very interesting for my needs. There might be reasons to come with PA by default, but if so, the distro should take care of those two lines in /usr/share/alsa/cards/ICE1712.conf. I wonder if it's easy to get rid of PA, when building dummy packages by equivs, to keep package dependencies consistent and what needs to be set up in addition?! Man, Envy24 cards are very common, because they are the most cheap rt capable cards, no distro should have issues when using those cards. Btw. there will come a successor for envy24control soon, maybe there already is a successor, I didn't lurk LAD the last weeks. For Suse only I'm running the first version + a manual edit of it's successor and it's still named envy24control, but AFAIR the renamed it. Cheers!

http:// mudita24.googlecode.com Please notice that there is a successor for envy24control. Nils and Tim did a good job. I didn't compile the current version myself, but I added the first overworks.

Anyway, you're mistaken, Envy24 cards are still sold in Germany and some cards should be much better, but my two Terratec EWX 24/96.

Hi :) when Niels and Tim started to program, there was an issue for the CPU usage, the newer version sometimes did stress the CPU more than the old Envy24control. I've got a cold and don't like to compile the current version right now, I'll compile it within the next days and test it then. For the first overwork I did compile and compare the versions. Some time ago, for the first overwork, I switched several times between /usr/bin/envy24control and /usr/local/bin/envy24control and watched both CPUs by htop. I dunno if the current version still is called envy24control, I guess you do know how it's called. If you've got the time to test it, please run top, atop, htop or what ever you prefer and compare the CPU usage when using the GUI. The old version should be in /usr/bin and because you didn't compile with prefix, the new version should be in /usr/local/bin. If there should be issues, you might want to report it to the list and Niels Mayer nielsma...@gmail.com. It's nice that they overworked Envy24control :).

Can't boot after kernel upgrade
Hi :)
I made a kernel upgrade from 2.6.32-24-preempt #39-Ubuntu to #4x-Ubuntu,

It's nearly a default Ubuntu Studio without the needed kernel-rt,
because I wasn't able to get a kernel-rt that's bootable for Ubuntu

There's just one relevant change, that wasn't a problem until now and

I still can boot Ubuntu Studio kernel 2.6.32-23-preempt and I do have a
backup for Ubuntu Studio with an older 2.6.32-24-preempt, but I won't
restore this backup, because I installed some apps, fixed Ubuntu Studio,
so that PA is fine with my Envy24 card etc., but it might help to get
the current 2.6.32-24-preempt version running?!

Sorry but my understanding of English is very limited. Could you explain your thoughts in a more simple manner? Thanks. Ciao, Alessio Hi Alessio :) my English is terrible broken too :D. I experienced the real-time kernels as the only valid kernels for audio and MIDI recordings. Anyway, when using a real-time kernel the set up needs some tuning and I always have problems with this tuning. First of all, on-demand for the CPU frequency scaling vs performance cat config-[...] | grep CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE should be set up to 'y'. I experienced that Rui's rtirq script doesn't have much impact, but it anyway should be included. On some machines JACK1 seem to work better and on other machines JACK2. A big problem is MIDI, when controlling stand alone devices, then jitter very often is an issue. If we run uname -a and the kernel is just a PREEMPT but a PREEMPT RT 'things' are more worse. IMO we only do need 'real' real-time kernels. We can't get hard real-time for modern PCs. Hard real-time only is possible when directly talking to the hardware, as it is done e.g. by the C64 on Assembler ... ask the UART if there's a byte ... LDA the register LSR BCC to LDA turn of the IRQ!!! ... SEI ... I'm unable to program for Linux, but for sure nor Linux, neither Windows is able to do this kind of hard real-time, e.g. to turn of all IRQs. The Linux folks who program the kernel-rt patches try to get as near as possible to the oldish hard real-time programming, any other kernel, but rt patched kernels aren't usable for music productions. Some applications might not use JACK in the best way, so they could cause xruns etc.. I'm really not the right person to teach this stuff, because I don't have the needed knowledge myself, but for sure Paul Davis won't recommend to run JACK and Ardour without a kernel-rt. We don't need latest Desktop candy supported by generic kernels, but well tuned disros + kernel-rt, to get a good audio workstation. Cheers!

Re: Natty and RT Kernel (was Maverick and RT)
You were asking for people using Ubuntu + Kernel-rt. I'm using 64 Studio 3.0 (Hardy) and 3.3 (Karmic) with the 64 Studio's multimedia kernel, which is a kernel-rt and several self build kernel-rt (vanilla + patch). Regarding to different distros based on Ubuntu vs all developers just to work on Ubuntu Studio: For example it's possible to add the 64 Studio repository to Ubuntu Studio, assumed they are based on the same version of Ubuntu (Karmic, Lucid etc.). I don't think that there are distros hat do use JACK as the sound server, but e.g. 64 Studio ships without PulseAudio, so all consumer desktop apps do use ALSA directly, which is an advantage for users who need JACK for audio apps, because without PulseAudio there's no pain for flashplayer etc., vene whe JACK is needed for Ardour, Qtractor or what app ever. And again a kernel-rt for Linux or ASIO for Windows does no hard real-time, it's still a soft kind of real-time, so anything less, but a kernel-rt IMO isn't good for a multimedia distro. I would like to see Ubuntu Studio supporting the kernel-rt. - Ralf -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users

Why does Ubuntu Studio comes without PREEMPT RT, but just PREEMPT?! This is my intension. FWIW, I'm a professional audio and video engineer and did program oldish computers and I'm missing hard real-time for modern PCs. Even the kernel-rt isn't able to do hard real-time, so I don't understand why Ubuntu Studio does prefer a kernel without rt-patch. Today the rt-patch isn't good enough and any kernel without this patch is useless for multimedia production. So a misunderstanding ;)! As I see, If a webserver used a RT kernel, it would have a lot of problems, because it will probably lock in some tasks until they are finished. Audio needs a very low latency, high resolution timer etc, because the Interrupts given by sound cards and by audio software need to be addressed as fast as possible, This is what I'm thinking off, I sometimes use the hr timer, that on Linux still is a PITA on some machines and for some apps. Anyway, if possible a multimedia distro should use hr timer (HPET), but always a kernel-rt only. if they arent, what happens is that the audio buffers, either for the souncard playback, or capture will run out of data, and then the continuos steam of audio data will be over, and wait until receive more info. In a Nutshell, you LOSE audio data, and you will never get it back, for professional audio that is unacceptable. Also if You give software RT priorities, it less possible that, for instance, Ardour is left behind of a twitter client unaceptable to... I am going to make some simple math with a not so professional cenario to ilstrate just the data stream, not audo software CPU time. Recording and monitoring out 8 channels (8 in 8 out) at 48KS/s at 24 bits 48000 * 24 = 115200 bps = 14.0625KB/s 14.0625 * 16 = 225 KB/s = 1.76MB/s Well, 1.76 MB/s is not to much really, well this calc is simple cenario, provided that the sound card uses real 24 bit audio data stream, if it used 32 bit, welll do the math. Now to a PRO setup.. 192 KS/s @ 24bits 192000 * 24 = 4608000 = 0.55 MB/s 0.55 * 16 = 8,78 MB/s 8.78 MBytes per second, not mbits, FIrewire is rated at 400 MBit per second... USB in practice is a lot less + Communication overhead. This is only on the Audio tranfer side, then you need to send this streams from each different software, make dsp calculations for Amplitude (volume) or mixing. This takes time so YES a Real time kernels is better for audio users than for normal users. Specially if you use Externals Firewire/USB card with high outputs note: this are simple calculations made fast, just to demonstrate the kind of stream we talk about. I assumed 24 bits, this is very rare, usually it goes with 32 bit, that is a lot more data to transfer. If some more explanation on why a RT kernel is prefered for audio, i can try to answer some more questions, i am not a pro in this tough.

I think the best compromise is to use the Hard RT kernel patch on top of vanilla kernel, and have the Generic kernel for everyday usage. You can choose which kernel to boot from at the beginning, I only use vanilla + rt-patched kernels for audio-video and everyday usage. The only difference is the CPU frequency scaling. For everyday usage I set it to ondemand and for audio-video work to performance and sometimes I manually enable hr timer when doing MIDI work. IMO just a kernl-rt is needed, but as I mentioned before, people running 32-bit architecture might need a patch to enable usage of large RAM. But indeed, GRUB is our friend, we are free to use several kernels. OT: GRUB is a little bit more user-friendly than GRUB2 is ;). Hard RT kernel, should be the only one to be supported, since it is the kernel that brings more benefits to audio/video production, If we spread attention with 2 more kernel flavours, no one can support it, and lets face it, abogani makes a hell of a good job, so we should simplify is life :D Hm, on my Ubuntu Studio, neither Abogani's, anyone else or my own build kernel-rt are ok :(. I can't boot any kernel-rt. I'm able to run Suse with my self build kernel-rt, but not with the repositories once and I'm able to run 64 Studio (Hardy, Karmic) with kernel-rt from the repositories and self build kernels. Live CDs, e.g. AV Linux are ok with the kernel-rt. Anyway, the rt-patch could be a PITA, while the PREEMPT only kernel for Ubuntu Studio is ok on my machine, as far as a PREEMPT only kernel is able to do some jobs, but I'm able to boot the kernel. IMO we only should take care of the kernel-rt and no other kernel. Hard disk drives today are less expensive so everybody should be able to install a distro for audio-video usage and if needed other distros for other usages, because not only the kernel makes a different. IMO a DAW e.g. don't need the security that's needed for some other usages. I'm running several Linux, no Windows, on my 2 core AMD 64-bit PC, for everyday usage and audio-MIDI productions, all Linux with kernel-rt only, excepted Ubuntu Studio, because I didn't had the time to troubleshoot why I'm unable to boot a kernel-rt for Ubuntu Studio. I prefer 64 Studio, but I really like Suse and Ubuntu Studio too, of course there are some other good distros, but those three are my favourites, even if Ubuntu Studio until today isn't ready for production. I like the concept of Ubuntu Studio, excepted of the default PREEMPT kernel, without rt-patch. This are just my personal 2 cents, the advantage of Linux, that we do have a lot of different paths we could go, even if it sometimes seems to be a disadvantage. Hard RT kernel (Ingo Molnar Patch) and an alternative (generic) for everyday usage if wanted. I reinforce the idea, that maintaining 3 different kernels is a very difficult task to acomplish, and more with the scarce resources available (humman and finacial) let alone the spinout distros that are popping out on top of the project 2010/9/30 Ralf Mardorf ralf.mard...@alice-dsl.net On Thu, 2010-09-30 at 17:45 +0200, Ralf Mardorf wrote: Hi Ricardo :) sorry for my broken English, especially at the moment, because I do have an influenza.

Ubuntu Studio as a project makes far fewer decisions that people probably expect. The kernel is a good example. The Ubuntu Studio team did not decide to remove the -rt kernel from the ISO image because we think it is inferior or that another kernel performs better. We would like to still be able to provide it to our users because we understand that it yields performance that other kernels cannot provide. We can no longer provide the -rt kernel in the ISO image because it is no longer in the official archives. Ubuntu Studio exists and must maneuver within Canonical/Ubuntu ecosphere. And sometimes decisions are made by Canonical or Ubuntu that grossly affect Ubuntu Studio. Some of those can be mitigated (e.g. ubuntustudio-menu vs. ubuntu menu with social integration) and others cannot. By the way, mitigating such things is a very good reason to keep building ISOs instead

[snip] Hi Scott :) I'm not sure, if I do understand the problem. Does Ubuntu need the same vanilla kernel version for different kind of kernels, e.g. to provide packages for proprietary graphic modules? If so, IMO it's not needed to make the multimedia distro full compatible with a regular Ubuntu. * snip * I think you are missing the point. It does not matter _why_ certain kernels are maintained and available in the repositories. It only matters _that_ the decision was made. The only kernels I can include within a Ubuntu Studio ISO image are the kernels available from the official Ubuntu archives. Furthermore, I do not decide which kernels may be included in the archives. That ultimate decision is made by others, although I may provide some small influence on it. This is an example of when I mentioned working within the Ubuntu framework. To summarize: Others control which kernels are available and maintained in the archives and I get to select from the available kernels which one to include in the Ubuntu Studio ISO image. To state what is needed or required or worthless without for multimedia production is irrelevant. I say again, to build a Ubuntu Studio ISO image within the Ubuntu framework I must choose from the available kernels in the repositories, of which I wield extremely limited influence in deciding which are to be available. Multimedia producer just need a kernel-rt and a package including the headers to compile e.g. drivers for graphics. For my needs the kernel-rt doesn't provide hard enough real-time, but the kernel-rt is a compromise that might enable some audio productions. You might wish to compare a C64, Atari ST or stand alone sequencer from the eighties with a kernel-rt and a kernel without rt-patch used by a good classical or jazz musician. There still is too much jitter, but the kernel-rt for sure will be the first kernel, that might be able to get the knack of it. The kernel-rt is the best we do have for Linux, hence it's invalid to use a less good kernel, as long as even the kernel-rt isn't able to do hard real-time. So, if there should be a rule for Ubuntu, that all patched kernels has to base on the same vanilla version, which is a good thought, it's not good for multimedia productions. There are coders who program the rt-patch, to make Linux better and better, it's not smart if a multimedia distro tries to be smarter by not using a kernel-rt, because it shouldn't be needed. The kernel-rt is needed and there should be no rule not to use it. Btw. to make the issue harder. It's not only that there isn't a rt-patch for every vanilla kernel, sometimes a current rt-patch-kernel-combination can be bad, so that we need to keep older rt-patched kernels. Sometimes it's not possible to keep 'things' that are available by a generic kernel of the same vanilla version, when using the rt-patch, but there's no need to keep all kernel features for real-time audio productions. * snip * No one is suggesting that the -rt kernel is not a good thing or that is not to be preferred over other kernels. However, stating that the -rt kernel is needed or multimedia production is worthless without it is not going to change the fact that the -rt kernel will not be included in an Ubuntu Studio ISO image for the reasons stated above. Furthermore, no one is stating that you should not use the -rt kernel. Quite the contrary, it is almost required for laptop users with firewire audio interfaces and we have made it very clear that we will make the -rt kernel available via a PPA. Again, this is not our choice to include a kernel other than the -rt kernel released in Ubuntu Studio. It is a necessity dictated by what is available in the repositories.

Hi Mike, downloading KXstudio is started. The ATI graphics on Linux is a PITA, that's why I switched to the NVidia card and I don't wish to switch back again. For the ATI I never got 3D support working on Linux, for the NVidia it depends to the used Linux, but even if I don't need 3D, since some years X is PITA regarding to set up frequencies and resolution for the monitors I used, resp. for the one I'm using now. For each Linux install I need to set up X by trial and error. Anyway, searching the web, I didn't find any information about the reason, that I don't get an initrd when building a kernel. Doing it the way I tried to do it for Ubuntu Studio does work for 64 Studio Hardy. I wonder what's different for Ubuntu Studio Lucid.

Then, to solve the problem and change which system booted by default, 1. Have a look at https://help.ubuntu.com/community/GrubHowto and https://help.ubuntu.com/community/Grub2 . From your description, you should have Grub1, but be sure of it. 2. Then depending on your Grub version you'll have to adjust a menu.lst or a grub.cfg and run some grub-update like commands. Again, see the wiki which has detailed instructions. Tell us whether this helped and if you have additional questions. Also for such issues, IRC can be a great place for more interactive help, in #ubuntu or #ubuntustudio on irc.freenode.net . Good luck! Ronan IOW take a look at the path '/boot/grub/'. There should be a menu.lst or a grub.cfg. If you're using GRUB2, as I unfortunately do, you should change /usr/sbin/update-grub to (something similar) as ... #!/bin/sh -e exec grub-mkconfig -o /boot/grub/grub.cfg_$(date +%b-%d-%Y_%H-%M-%S) $@ ... if you don't do it, resp. you try to follow the idea of GRUB2 to use all those 'special' files, you won't be able to configure and keep your personal, customised menu.

HI Ralf, thanks for your many responses.
As you can see from what I've written Ronan, there may be more going on
here rather than not seeing anything (initially).
Did the install of UbuStu 10.04 happen or not?
Thoughts?
Mischa
With a live cd or from the Linux that can be booted copy
/boot/grub/menu.lst
or
/boot/grub/menu.cfg
to an email to the list. I guess just the menu entries are missing.
Take a look at all partitions. If there are folders /boot on some
partitions there should be the kernels. For any kernel there has to be
an entry in /boot/grub/menu.lst, for /boot/grub/menu.cfg it can be a
little bit complicated.

i think it would have been a good idea to get the older install (8.04)
up to GRUB2, then install the 10.04 (with GRUB2). i would try reading
over the GRUB2 wiki page https://help.ubuntu.com/community/Grub2 ,
also maybe
this https://help.ubuntu.com/community/RecoveringUbuntuAfterInstallingWindows
i have used http://gag.sourceforge.net/ in the past, you could try it
or another 3rd party bootloader and see if you can find your OS's...
good luck
Hm? I guess we could help him with GRUB too, anyway, GRUB2 isn't that
bad for such a situation.
After installing GRUB2 it's always possible to
run /usr/sbin/update-grub, which will execute grub-mkconfig, hence a
menu list with every possible kernel will be generated, if wanted or
unwanted ;). It's still possible that some entries are bad, but at least
everything is added.
Maybe a good idea to switch to GRUB2, because it's the default
bootloader for newer Ubuntu.

Re: Shifting pitch in a MIDI file?

My situation is as follows. I have a MIDI file of a piece (for four guitars), and I just want to mute one of the tracks and play along with my real guitar (a sort of virtual quartet...). But the problem is that the tuning of my computer is wrong (I read somewhere that DELL laptops had this problem. I'm not sure, but in any case the standard A at 440Hz sounds actually like a C). I could tune up my guitar, but that is quite inconvenient, specially if later I want to play with more instruments, so I was hoping that I could find a way to tune up or down the whole MIDI output. The Virtual Keyboard has a pitch wheel, which it would be exactly what I'm looking for if it could be applied to the whole MIDI output... In Rosegarden I didn't find anything... In Qtractor I could load up plugins that seemed promising (if I remember correctly I could find four plugins with names like pitchshift, but I couldn't make them to work, plus they applied to individual tracks, and not to the whole MIDI output). Any pointers? Thanks, Ángel de Vicente Add a track and send Pitch to all channels, but note, that the steps for the Pitch Wheel are defined by the synth e.g. 0 or 2 or 12 semi steps ;). MIDI does also know a master tune, but this isn't supported by every synth. You might have not an issue for the sample rates, regarding to the bad tuning, I once had this too. I did a new install and the tuning was ok. Perhaps you can record the MIDI instruments to audio tracks and fix it with rubberband or a pitch shift effect, if it's not to extremely out of tune.

This is for practice with my guitar, so I like the ability from Rosegarden to change the tempo, play it slowly, and increase the speed as I get better at it, so I would prefer a way to do it from the MIDI sequencer.

I'm a complete newbie on these matters, so I might be completely wrong, but I thought that sample rates were relevant to audio files, but not to MIDI files? Well, I think the problem is not even related to the MIDI file: If I just play A in the Virtual Keyboard, it does not play a 440Hz A, it is somewhere around C.

In case you are unsure how to set it up properly, press the Setup button of Qsynth, then select the Audio tab and try the various options available for Sample Rate. The ones most likely to work would be 44100 or 48000. yes, that was the problem. Jack was set to 48000 while Qsynth was set at 44100. When both are at 48000 the Free Music Instrument Tuner reports a nice 440Hz Concert A with the Virtual Keyboard. But this doesn't seem to affect the other synth that I tried: ZynAddSubFX: with this one, either 44100 or 48000 sample rate produce a concert A in tune... In any case, I think the problem can be considered solved now.
