[LAU] The Drummer's "Gigsaw": 3 Virtual Books

by Philippe Hezaine

Hi all, 3 new books are published: Le-Puzzle-du-Batteur-VIRTUAL-ROCK-BASE-en-5-4 + MY-SONG file. Le-Puzzle-du-Batteur-VIRTUAL-BLUES-BASE-en-5-4. Le-Puzzle-du-Batteur-VIRTUAL-ROCK-BASE-en-7-4. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% WHAT IS A VIRTUAL BOOK? In this book all bars are formated in 5/4 but only completed with rests. Therefore at the end of each bar there are two r8 (= a quarter note). Don't forget that you must write sounds with eighth notes in the "Gigsaw". If that's been established all combinations are possible: Move and replace whatever place you want into the bar a single r8 (or its subdivisions). (In the included MY-SONG see example 5/4-VIRTUAL-ROCK-BASE mes8) Paying more attention in case of triplets that's the reason why I haven't changed 8th rests in the following examples: - Either you move a WHOLE triplet on one another beat. (see example 5/4-VIRTUAL-ROCK-BASE mes5 (transformée 1) - or you insert three 8th rests inside one another triplet and delete the empty \\times { } so that you only get a triplet with six 8th notes. (see example 5/4-VIRTUAL-ROCK-BASE mes5 (transformée 2) - or you only get a triplet with nine 8th notes. (see example 5/4-VIRTUAL-ROCK-BASE mes5 (transformée 3) - or you only get a single triplet with twelve 8th notes. (see example 5/4-VIRTUAL-ROCK-BASE mes5 (transformée 4 et 5) - or finally you change the time signature (5/4 becomes 15/8) and you delete all \\times { }. Doing that you create materials for all kind of transformations. (see example 5/4-VIRTUAL-ROCK-BASE mes5 (transformée en 15/8). To find the previous tempo of 8th in triplet again notice the change of tempo 4 = 165 (110 + a half: 55) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% You'll find these packages at: Le-Puzzle-du-Batteur-VIRTUAL-ROCK-BASE-en-5-4. http://philippe.hezaine.free.fr/spip.php?article54 Le-Puzzle-du-Batteur-VIRTUAL-BLUES-BASE-en-5-4. http://philippe.hezaine.free.fr/spip.php?article53 Le-Puzzle-du-Batteur-VIRTUAL-ROCK-BASE-en-7-4. http://philippe.hezaine.free.fr/spip.php?article55 I spend more time to explain than to do the things. I hope my effort at doing a translation wasn't too unclear. As always suggestions or criticisms are welcome. Have fun. -- Phil.

[LAU] [ANN] a2jmidid version 6 "Indzhe Voyvoda" released

by Nedko Arnaudov

a2jmidid is a project that aims to ease usage of legacy ALSA sequencer applications, in a JACK MIDI enabled system. Homepage with screenshots: http://home.gna.org/a2jmidid/ Tarball download: http://download.gna.org/a2jmidid/ Changes since version 5: * MIDI processing improvements * Handle large number of ports * a2j script (non-dbus-like behaviour for dbus environment) * Allow tweaking through dbus of the hardware port export option * Fix a use of invalid memory * Fix port miss that can occur if port appears during bridge startup Special thanks to Torben Hohn and Paul Davis for their recent work on improving the a2jmidid code. Indzhe Voyvoda was a renowned leader of an armed band of outlaws in Ottoman-held Bulgaria. Eventually, he gave up robbing and began to patronize the poor Bulgarian population. -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

[LAU] Clicktrack in audacity causes seg fault

by Scott

I'm not getting any useful responses at Audacity's forum... When I try to generate a click track the following error is displayed: ERROR: Could not find sinewave.raw in rawwaves. Something is wrong with the installation or configuration. ; loading "/usr/share/audacity/nyquist/init.lsp" SETDIR: No such file or directory Set *default-sf-dir* to "/usr/share/audacity/plug-ins" in fileio.lsp AutoNorm feature is on. Default sound file is scott-temp.wav. system.lsp : *RUNTIME-PATH* = /usr/share/audacity/nyquist/ Nyquist -- A Language for Sound Synthesis and Composition Copyright (c) 1991,1992,1995,2007-2009 by Roger B. Dannenberg Version 3.03 error: too few arguments The second time I run it the following error occurs and Audacity crashes: 1> Segmentation fault Can this be fixed by creating a sinewave.raw audio file in the default path specified or is there something wrong elsewhere? What's the fix? Using Audacity 1.3.9 (Unicode) on Ubuntu 9.10 x64 and Fedora 12 x64 and i386. Same error in all environments.

[LAU] music similar to ColdPlay "Clocks"

by Christian Einfeldt

I am looking for some Creative Commons by-SA music to use for a video piece. I would like the music to be pulsing and sweeping in sound similar to ColdPlay's "Clocks". Thanks either way for any help. This music will be included in a video short for a movie about how FOSS is changing global culture called the "Digital Tipping Point." We are giving away all of our footage here under a CC by-SA license. We have 100 hours of forkable footage posted here: http://archive.org/details/digitaltippingpoint thx c u -- Christian Einfeldt, Producer, The Digital Tipping Point

[LAU] Beatrix in the house

by Ken Restivo

I somehow seem to have acquired a non-context sort-of-patch to add JACK audio and ALSA MIDI support to the orphaned last release of Beatrix. Many thanks to whomever did that! I had to make a few minor modifications of my own, which, sadly, I'm not allowed to redistribute either. Basically I added support for Note On Velocity 0's instead of Note Off's, fixed a denormal problem in the whirl (the Leslie) function, made the ALSA MIDI reject events on MIDI channels greater than what it could support, whacked the reverb since I don't use it anyway, and adjusted the Leslie SLOW/FAST code so that it works with the Modwheel (as I'm used to from AZR-3, making Beatrix a drop-in replacement for it). And, to celebrate, I created a small demo: http://www.restivo.org/blog/podpress_trac/web/492/0/beatrix-martin-wood-mix… Please excuse the crappy drumming: I tapped in the drums on pads, since this was all done in Mplayer and jack_capture, no sequencers used... hence the clipping at the end too. Happy holidays to all! -ken

[LAU] Guitarix presets?

by Dan Muresan

Hi, I was wondering if there is a collection of "good" presets for Guitarix somewhere? Rakarrack comes with some useful presets, but guitarix seems to include none in its default installation.

[LAU] [OT] looking for 8ch preamp with a/d and calibrated (or even digitally controlled) gains

by Jörn Nettingsmeier

hi everyone! i'm shopping for a new 8-way mike preamp with calibrated and steppered (or digitally controlled) gains (to allow for precisely gain-aligned soundfield recordings). it should include an a/d converter to adat. specifically, it should be low-noise and must have a very robust phantom power section that can take 8 schoeps or other misbehaved phantom current guzzlers without stress symptoms. gain of no less than 60dB would be nice. can anyone recommend anything in the <2k price range? ultimately, i'd want one of those micstasies with a madiface to go with it, but first i need something more affordable to earn some cash with :) i don't much care for input impedance wizardry, i like my mike ins hi-Z, thank you very much - if i don't want that bright treble, i'll filter it later... :) your recommendations are appreciated! best, jörn

[LAU] lash annoyance: automatically created directories

by Philipp Überbacher

Hi there, for a long time I've been wondering where ~/audio-projects/New Project is coming from, and why it always comes back, no matter how often I delete it. Now I found the culprit: lash 0.6.0~rc2 I don't know whether other versions do the same, either way, it's annoying, and I wonder how to get rid of it. Regards, Philipp
