Greetings, I'm writing an article about using Jaunty for a desktop recording platform, so of course I had to create a demo. Out of sheer laziness I decided to record a song written by someone else, thus we now have: http://linux-sound.org/audio/idontworryaboutathing.ogg And for the OGG-deficient: http://linux-sound.org/audio/idontworryaboutathing.mp3 The song is a great Mose Allison tune. The recording was quick & dirty, done entirely (and literally) from the desktop. All parts performed by DP except the drums, which are once again from the Beta Monkey Jazz Essentials collection. Vast thanks to the Ardour devs. What an amazing program. Enjoy, and comments are welcome. Go easy on me, folks, this one was a real rush job. Best, dp

PHASEX-0.12.0-beta3

by William Weston

Announcing the new public beta release of phasex! All phasex users are encouraged to upgrade. Since the days of 0.11.1, all known bugs and many annoying quirks have been worked out, making PHASEX-0.12.0-beta3 is the most stable, best sounding, and most studio friendly release yet: * Fixed all currently known crash issues and build issues. Code has been updated for newer versions of gcc, gtk, and glibc. Realtime threading issues have been fine-tined, using realtime locks where appropriate. The build system has been fixed up for newer distributions and includes default optimizations for the entire x86 family (run './configure --enable-arch=foo', where foo is an architecture supported by your version of gcc). * Sound quality has been greatly refined by reshaping envelope curves (eliminating pops and clicks), adding hermite interpolation to the chorus (removing fuzziness from chorus), adding fine tuning to oscillator frequencies and FM amounts, adding sampled oscillators (currently with Juno-106 and vocal samples), fixing portamento and key triggering logic, and more. * The JACK code has been reworked to allow multiple instances with persistent instance numbers and resilience to JACK crashes and restarts. * The GUI has been refined slightly, with a new color scheme, patch folders in the file dialog shortcuts list, and a couple slight optimizations to the knob code. * There's more. See http://sysex.net/phasex/beta for details if you're that curious. Since 0.12.0-beta2, fixes have been implented for GTK >= 2.16 (fixing Fedora 11 builds), the max polyphony has been turned into a runtime configurable setting, and the build system and default architecture specific optimizations have been fixed up some more. Source tarball and arch specific Fedora 11 RPMS are now available for download: http://sysex.net/phasex/beta/phasex-0.12.0beta3.tar.gz http://sysex.net/phasex/beta/phasex-0.12.0-0beta3.fc11.src.rpm http://sysex.net/phasex/beta/phasex-0.12.0-0beta3.fc11.i386.rpm http://sysex.net/phasex/beta/phasex-0.12.0-0beta3.fc11.i586.rpm http://sysex.net/phasex/beta/phasex-0.12.0-0beta3.fc11.i686.rpm http://sysex.net/phasex/beta/phasex-0.12.0-0beta3.fc11.athlon.rpm http://sysex.net/phasex/beta/phasex-0.12.0-0beta3.fc11.amd64.rpm http://sysex.net/phasex/beta/phasex-0.12.0-0beta3.fc11.x86_64.rpm http://sysex.net/phasex/beta/phasex-0.12.0-0beta3.fc11.ia32e.rpm Build reports and bug reports, and package build files for all distributions are highly welcome. This is the final beta for 0.12.0. Any build and crash issues reported in the next two weeks will be fixed for the 0.12.0 stable release. Please direct any feedback to weston(a)sysex.net. The latest version of phasex can always be found at: http://sysex.net/phasex For those of you who use git: git clone http://sysex.net/git/phasex.git Thank you all for your support, feedback, and contributions over the years, helping to make PHASEX what it is today. Happy music making! --ww

How well do thinkpad notebooks work for audio?

by hollunder＠gmx.at

It feels like my several year old PC will crap out soon for one reason or another, so I need a replacement, better sooner than later. This time it should be a laptop and I heard that formerly IBM and now Lenovo thinkpads are of good build quality, even if they only come with intel CPUs and cost an arm and a leg. So, do you have any experience with those for audio work? I'd be most interested in the T and R series and more recent models. Also helpful would be some data that's impossible to find on websites: - What chipsets are built in? - do the usb buses and the like share interrupts with something nasty like graphics? Helpful commands to gather that data: cat /proc/interrupts lspci lsusb Thanks in advance for any help. Regards, Philipp

MIDI clock & sync

by Josh Lawrence

Hi everyone, Atte's recent thread about sync got me to thinking about MIDI clock. Is there a simple app out there that will generate MIDI clock at a tempo can can be defined? If not, would one of you scripting/programming wizards be willing (or able, if what I'm asking is possible) to drum something up? Thank you, Josh -- Josh Lawrence http://www.hardbop200.com

Why Debian necessarily?... WAS... Re: The Many Ways of Pam Limits...

by sonofzev＠iinet.net.au

>> Agreed. >> >> If you want a Debian-based system, Ubuntu is much more focused on >> requirements for a general-purpose desktop. Not specifically for >> musicians of course, but easier to adapt for that purpose. > >maybe it is more of a trade-off - This is the big If?.. Why specifically a Debian based distro? Are you looking for the best performing music workstation, a politically correct distro, a server or a general purpose desktop? If the answer is music workstation, why does the choice need to be limited to Debian? Many would argue (including myself).. that a ground up type of distro, like Gentoo, Paludis or Arch are the best way to start. Although Debian if carefully installed will fit into this category. I have also found this personally in experience too. I've tried the pre-built distros for music Studio64, Apodio and UbuntuStudio and GP desktops Mandriva and Ubuntu and found they were a) bloated b) did not contain everything I needed or had old versions of what I needed c) trying to add things not in the repos was more than trivial d) did not perform as fast as as a ground up distro... e) a nightmare come upgrade if any customisations have been made.. Comparatively, I have a number of purpose built Gentoo systems (1 server, 2 media pc's and one studio computer) and while they take an initial amount of work to built, once built they are very reliable, and perform amazingly quickly... Should an app not be available through portage or an overlay .. it is trivial to install from source.. My audio machine is now back on a standard (gentoo-sources) kernel, I have done very little in PAM and get fantastic latency results. Reports from friends using Arch reflect a similar situation. However, for those looking for an easier option.. AV Linux looks like an amazing option.. although it is more of an image that needs modification rather than a distribution per-se. And yes it is debian based... But to re-iterate my question.. why necessarily a debian based solution, why not simply look for something that will give you a reliable, fast performing music machine? Debian may be able to provide this, but why limit the initial question to something debian based? cheers Allan

is there a controller like this?

by andy baxter

Hello, I have just bought a second hand keyboard, (edirol PCR-500) which has loads of knobs and sliders on it. The trouble is that all the knobs are pots, not rotary encoders; encoders would be much more useful I think because it would mean that if you press a button to switch to a new synth or effects patch, the correct defaults for it could be automatically loaded to each of the knobs when you switch. Without that, it seems like whenever you switch to a new instrument you would have to spend a while tweaking all the knobs to get the right basic sound. What I would like is a device with a couple of rotary encoders on it (you only have two hands), maybe 16 buttons, and a character LCD screen. The way it would work is (something-like): - one of the buttons would be for loading new instruments. To switch to a new instrument, you would press the button and then turn either encoder. The LCD would show which instrument you were choosing from a list, and you would press the button again to make the switch. - most of the buttons would be for accessing different midi controls. You could assign a midi control to an encoder by pressing the button for that control first, then pressing a button underneath the encoder you were assigning. - having done this, that encoder would be bound to that midi control - turning it would send out midi messages for that control, and also update a display on the LCD saying what the level of that control is currently set at. - loading a new instrument would automatically set the right default levels for each controller that that instrument used. Does anyone know of anything like this that's already being made? If so I might get hold of one and see if I can hack it to work with linux; if not I'm thinking of having a go at making my own some time. cheers, andy baxter.

LAM etc

by Viktor Mastoridis

Guys, I was wondering: Here, http://dis-dot-dat.net/mailman/listinfo/lam_dis-dot-dat.net I read this: *About LAM* English (USA) LAM is a mailing list for posting you Linux-made music, getting feedback and finding collaborators. Software trouble should be discussed in LAU and the coding side of things should be sent to LAD. But there it seems that only one person (Julian) posts his music in the last two years. I see that music is been posted on all LA- lists occasionally, but I was never sure whether it was the right place for posting (the various LA- lists) It would be nice to have a place where Linux music is posted and people (audiophiles/musicians/linux geeks) make comments about it and generally, hang out, say like http://www.zoxsy.com/ Any ideas, suggestions about it?

Re: [LAU] Korg NanoKontrol editor?

by Kim Cascone

I found a pdf of a MIDI implementation chart for the KORG padKONTROL *not the nanoKontrol* but it might be similar enough to get people started on patching something up in pd http://kpkproject.twoday.net/files/Padkontrol-Sysex-Imp/

Best realtime audio dstro for Eee

by Norval Watson

Hi y'all, I want to install a realtime audio distro on my new Asus Eee 901. I need a 2.6.29 realtime kernel or higher to support the hardware on my Eee. I have got the 2G RAM (haven't swapped it in yet). AFAIK, options include: DebianEeePC http://wiki.debian.org/DebianEeePC ArchLinux http://wiki.archlinux.org/index.php/Asus_Eee_PC_901 Eeebuntu http://www.eeebuntu.org/ Indamixx USB stick, when it's available, (and it's not free) I have been using Debian unstable for some years so I'm most familiar with that. Any suggestions welcome, particularly regarding optimizing the kernel. TIA Norv Need a Holiday? Win a $10,000 Holiday of your choice.
