[LAU] [OT] guitar pickups: how to get separate signals for each string?

by Shane Richards

Try talking directly to the manufacturer. Instrument/amp builders are usually really open and easy to talk to. http://www.godinguitars.com failing that, I remember that Streetwater Sound Inc. were a dealer. http://www,streetwater.com >also, i'd be interested to learn of replacement pickups for other >guitars in humbucker or single coil format that provide six signal outs... Gibson might sell you one without the attached guitar if you get a dealer to talk directly to them However... Rewiring a pickup yourself is a very enlightening and satisfying excercise. Of course I was 19 or 20 and had the time, but it really was a fun project. Connections/cable and needing six amps was a bit of a problem, though. :/ - shane

[LAU] New Piece!

by Kevin Utter

Hi all. Julien suggested I post this, and is hosting it for me as I only have short-term storage at present. This was a birthday present for him. <http://juliencoder.de/q/BirthdayFugue.mp3> http://juliencoder.de/q/BirthdayFugue.mp3 I did the original MIDI file in Windows, but from there all was done in Linux. MIDISH to play the MIDI file, and Nama/Ecasound for recording. The organ is a jOrgan disposition for an American Classic organ, perhaps something in the style of the 1930's/40s. jOrgan is playing SF2 soundfonts through Fluidsynth. Enjoy. Kevin

[LAU] Someone on list was looking for laptop with Firewire port?

by david

System76's Gazelle includes Firewire, plus USB3 and USB2, and includes Intel SSD's as drive options: http://www.system76.com/product_info.php?cPath=28&products_id=113 They supply it with 64-bit Ubuntu 10.10 installed. I have no connection with System76 beyond the fact that my best friend has bought a couple of systems from them and been very happy with machines. He doesn't do pro audio stuff, though! -- David gnome(a)hawaii.rr.com authenticity, honesty, community

[LAU] Jack uninstall problems

by headless

Hi all! I have some strange problems with my jack-install. I know some time ago i experimented with different versions of jack. Means i compiled them. Later I installed the normal jack2 from my debian-distribution(Now squeeze 64 bit) but it seems i didn't remove the compiled one. I recognized this now and thought maby jack is using some of the libs in /usr/local/. I could not find the src directory anymore, so i just manually removed everything jackish in usr/local. Now surprisingly jack does not want to start because it doesnt find the libs in /usr/local/libs/jack. I reinstalled jack2 and libjack from debian and even made a symlink from /usr/lib/jack to /usr/local/lib/jackand jack is still complayning that it cannot handle the librarys in local/lib/jack. What can I do besides reinstalling my whole system? thx, headless

[LAU] OpenOctaveMidi2 (OOM2) beta release

by alex stone

Deep in the basement of the OpenOctaveProject, the team have been working hard, to bring OpenOctaveMidi into the modern age. From the new interface, to the workflow features, OOM2 is the result of a great deal of hard work, and thought. In our Project journey towards a great Linux Audio pipeline, OOM2 represents the next important step. With the help of our platinum sponsor TSI, we were afforded two full time developers to help with the task of getting to where we are today. We would like to thank TSI for their continued longterm support and encouragement. OOM2 linear Midi and Audio sequencer. We announce the beta release of the 2nd version of the OpenOctaveMidi sequencer, known as OOM2. After a change of codebase, a complete rebuild of the user interface, and the addition of new features and functions, we're proud to present this version as our initial beta release. OOM2 is a linear Midi and Audio sequencer for the Linux operating system in both 32 and 64bit. OOM2 uses the following: * JACK-audio - http://jackaudio.org * JACK-midi - for midi support * DSSI - synth plugins * VST(i) - synth plugins (through DSSI, for the moment. We're more interested in native linuxplugins, so the DSSI-VST implementation may be removed.) * ALSA-midi - for midi support * QT4.6.0 or later (earlier versions may work, but are not tested) You can download OOM2 from our github repository at: git://github.com/ccherrett/oom.git Use the command: git clone git://github.com/ccherrett/oom.git to install the source in an empty directory of your choosing, and follow the build instructions in the Readme file. Please note we're adding new commits each day, and more features are coming very soon, hence the Beta release notice. We hope you enjoy using OOM2, and should you have anything you'd like to report, please send an email to: development(a)openoctave.org We can also be found on irc at #openoctave (freenode) Visit www.openoctave.org to find out more!

Yoshimi zombified 3 times though, probably because of asking to much from my cpu. The mp support of Jack2 seems to be an advantage when it comes to cpu load. \r

[LAU] Balance between performance and noise

by rosea.grammostola

Hi, When I set cpu scaling with sudo cpufreq-set -g performance, I have the best proaudio performance on my thinkpad T61. But, that will also heat things up very quickly with as consequence more sound from the fans. The laptop is more silent when I use, sudo cpufreq-set -g ondemand, but I get more xruns then. Is it possible to adjust the ondemand settings to find more balance between performance and noise? How? Btw., I use thinkfan to control the temperature and fan speed http://thinkfan.sourceforge.net/ My /etc/thinkfan.conf settings are: sensor /proc/acpi/ibm/thermal (2, 7, 8, 0, 0, 0, 7, 0, 12, 5, 5) (0, 0, 54) (1, 50, 57) (2, 52, 59) (3, 54, 63) (4, 56, 65) (5, 59, 66) (7, 63, 32767) Thanks in advance, /r

[LAU] Sorta-OT: Linux phones?

by Ken Restivo

It's sorta-off-topic, but my Sprint contract ends next month, and I'm looking to shake up my phone/mobile-network situation. I'm looking at other providers (and I refuse to use Verizon on principle, becuase they are unscrupulous thieves, but that's a different story). Well maybe it is on topic, because I would LOVE a smartphone that runs linux and has a hardware QWERTY keyboard, and even better if it could at least theoretically run fluidsynth and jackd and aseqnet. The perfect phone to get seems to be the N900, since Linux runs on it explicitly with manufacturer support and usability, but it is very expensive (US$300 used). There are, however, very many used smartphones on Craigslist for a third or less of that price. I'd prefer going that route. But which run Linux? It's a zoo. There doesn't appear to be any nice clean table anywhere showing what phones can or can be made to run Linux and to what degree they actually work. Any advice? I'm told some of the older HTC's out there have been made to run Linux, but the documentation on that hasn't been too encouraging. It's a cost-versus-risk thing. If I can find a US$30 phone with sort-of-might-work-on-linux, then I'll take the gamble and try to get it running, and just resell it if I can't. If I'm going to spend US$100, I need the thing to pretty much be guaranteed to work. And if I've got to spend much more than that, I might just keep saving up for a while and get an N900. Thanks. -ken

[LAU] OSC - where to start?

by James Morris

Hi, I want to start using OSC to see what can be done with it. What options are there for sending OSC messages? For instance, what can I use to type OSC messages (or assign them to keystrokes) and then send them? Just something that is a good general purpose program and not specialized to OSC messages for a particular application so that I can start playing with it. Cheers, James P.S. Prompted by a GUI freeze in Ardour and me wondering if it would respond to OSC.
