Re: [LAU] MTC syncing Ardour to hardware sequencer as a slave

by sonofzev＠iinet.net.au

So you do have the MTC/SMPTE chip installed. I don't believe it responds to MTC otherwise.

[LAU] phasex-0.12.0-beta4

by William Weston

Greetings, Thank you for all your great feedback on the last two betas! phasex-0.12.0-beta4 addresses all of the concerns brought up so far: Velocity: Many of you have noticed that velocity and aftertouch were completely unsupported. Now, velocity (with aftertouch) can be mapped to directly to oscillators and LFOs (by setting the source), used as a modulation source (adjust volume w/ AM or pitch w/ FM), or mapped to the filter in the filter-lfo section. GUI: Some of you mentioned that the colors were too dark with too little contrast, so now there are four GTK theme options: Dark (original purple background), Light (orange background), System (use the system GTK theme), and Custom (choose any gtkrc file for your theme). There have also been issues with getting phasex to fit on small screens (usually netbooks). The knob images have been trimmed down vertically (just blank pixels), and the padding between widgets has been almost completely cut out. The font can be selected in the preferences. Additionally, a true fullscreen mode has been added. It is now possible to fit phasex into an 800x600 desktop. Atom processors: Compiler optimization flags for the Intel Atom processors have been added to the build system. Run './configure --enable-arch=atom' to build for the Atom. To force 32- or 64-bit builds, use 'atom32' or 'atom64'. The rest is just small tweaks and bugfixes, such as fixing the segfault on quit issue, fixing all the compiler warnings, minor updates to the build system, new menu items, etc. As I don't have access to a netbook right now, please let me know how it works out with the Atom or other low-power CPU, or on any machine with a screen smaller than 1024x768. Of course, feedback from the rest of you is highly welcome, too ;-} Visit http://sysex.net/phasex/beta for source tarball, Fedora 11 RPMS, or Fedora 8 RPMS. Cheers, --ww

[LAU] some live tracks - need some advice

by Dave Phillips

Greetings, I've posted some recordings from a performance of my band last Saturday night. The tracks are simple unprocessed and unmastered board recordings, made by the soundman for the gig. As such they're intended primarily as a record of the performance, but I'd like to use some of them for tracks on a CD to sell at gigs. Here's where I need the advice. As you can tell, the bass is too well-recorded (it had a direct line out). I'd like to be able to diminish its presence, but I think I need some advice on using EQ. Also, the originals had no processing, so I added a bit of CAPS Stereo Versatile Plate in ReZound. I'm curious to know what others here might do. Alas, there are no multichannel/multitrack versions, I have to work with the present stereo mix. You can hear the tracks here: http://linux-sound.org/audio/Woke_Up_This_Morning.ogg http://linux-sound.org/audio/Outside_Woman_Blues.ogg http://linux-sound.org/audio/I_Dont_Know_Your_Name.ogg MP3 versions are also available (s/ogg/mp3). I'll send them through JAMin later today, so any advice re: using JAMin would be especially helpful, but I'm interested in any & all responses. Btw, ReZound and the encoders were the only Linux audio software used for these tracks. Enjoy, critique, keep breathing. Best, dp

[LAU] Fons' auto-wah, live in action

by Ken Restivo

Here is Fons' great auto-wah plugin, being used live: http://www.pringlized.com/lahar/Song_3_flv.htm This was the first time I'd played with these guys, and so I wasn't entirely 100% sure of the arrangements or body language. So I screwed up a few times in there, oops. Also, the sound guy had the keyboards really hot in the mix. But, at least you can hear auto-wah happening, big time. Thanks, Fons! -ken

[LAU] 64 bit systems

by Russell Hanaghan

I am almost convinced that I want to go Linux audio in my studio. I have a x64 3ghz dual core AMD based box that is my dedicated DAW. I am now deciding which distro to use that will give me stable performance with minimum effort. 64 Studio would seem like an obvious choice but because I would like to have VST's available, I seem to recall that is a possible issue? Beyond that, is there any other advantage(s) to using a x64 OS other than RAM access beyond 4gb? Is there any 32 bit OS performance degradation when installed on a x64 machine? Thanks, Russell

[LAU] The Drummer's Gigsaw: 2nd edition

by Philippe Hezaine

The Drummer's Gigsaw: 2nd edition There is a gap in the free world about to find pre-built drums patterns as a drum machine. As the novice as the song’s composer who wants to outline an arrangement, the assessment is: there’s still no consistent free database about drum patterns. The project "Le Puzzle du Batteur-The Drummer’s Gigsaw" aims to fill this gap. In due course there will be a duplicate copy but for a real drummer. It's published under a GPLv3 License. New: - You have to add a command in your /home/.vimrc See the README. - There is an INSTALL.sh script now. I hope it will be more user-friendly to install the Gigsaw. - There are no longer acute accents in the files. - there is one more repertory: DEBUG - I added two scripts: 00-automate-Batterie-seule.vim 00-automate-Percussions-seules.vim and their corresponding templates: Z-2-modele-Batterie-seule-22pistes.ly-0 Z-2-modele-Percussions-seules-26pistes.ly-0 You'll call them from MA-BASE/0-run-process. Download here: http://philippe.hezaine.free.fr/spip.php?article46 So far I didn't get any feedback. It wasn't working, was it? I believe I finally found the cause for this. Would you be kind enough to tell me if you get MY-SONG+veloc out. Feedback... feedback... feedback... as a long moan in the desert. :=) Thanks in advance. -- Phil.

[LAU] jconv settings

by rosea grammostola

Hi, I'm trying to understand the fantastic reverb jconv. I know how I can run it. 1. in/out is number of ins and outs 2 partition is frames and should be the same as in jackd(?) 3. maxsize is length of the file? In what format (kb?), should I customize it using different files? What app can I use to determine the length of the file? How? 4. Should I do anything with delay/offset/length? 5. I'm especially interested in the settings for guitar (if you know some nice Jazz IR files, tell me) 6. For what kind of instruments do you use reverb? Thanks in advance, \r |# in out partition maxsize # ----------------------------------------------- /convolver/new 1 2 512 120000 # # # num port name connect to # ----------------------------------------------- /input/name 1 Input # /output/name 1 Output.L /output/name 2 Output.R # # # in out gain delay offset length chan file # ------------------------------------------------------------------------------------- /impulse/read 1 1 0.2 0 0 0 1 greathall.wav /impulse/read 1 2 0.2 0 0 0 2 greathall.wav|

[LAU] phasex-0.12.0-pre1

by William Weston

Announcing phasex-0.12.0-pre1: The pre-release is here. It's stable. It builds cleanly. No build errors or warnings. No runtime errors or crashes. No glitches. If no bugs are found in the next week, then this code (with the addition of some brand-new patches) will become the stable release. Changes since phasex-0.12.0-beta4: - Build system overhaul. GCC version detection for better arch- specific optimization (compiles clean with gcc-3.4.x or higher). Atom builds fall back to next-best optimizations for GCC < 4.5.x. New --enable-32bit and --cpu-power-level= flags and better user variable handling for ./configure. Missing -lpthread in link phase is fixed. - Velocity control for the amplifier. Better aftertouch handling. - Scheduling policy defaults to SCHED_RR, and can be changed in the settings at runtime. - Broken ringbuffer code has been fixed. No more glitches (unless you have actually run out of CPU). - Theme loading has been fixed. Now properly detects if the nodoka theme engine is installed, and quietly falls back to an engineless theme. - Fullscreen and Maximize interaction have been fixed. - New command line options: -m (--midi-channel=), -f (--fullscreen), and -M (--maximize). Loading a patch by name or by program number on the command line now finds the appropriate patch in the patchbank. - The lurking patch name corruption bug has been fixed! - And more. See the ChangeLog for details... Download phasex and hear for yourself... http://sysex.net/phasex/ Alternatively, you can utilize the git repositoty: git clone http://sysex.net/git/phasex.git Cheers, --ww
