[LAU] Comparison between Qtractor and Ardour?

by Roberto Suárez Soto

Hi, I've only used Ardour, but I've seen Qtractor mentioned quite a bit here. I had never really paid attention to it, thinking that it was some kind of quirky software for electronic music composers. But today I was curious and I browsed its web page. It seems to be a simpler version of Ardour, to my ver unexperienced and unknowledgeable eyes. Is it so? Is there some comparison between them that I can check to know more? Thanks in advance. -- Roberto Suárez Soto

[LAU] [Ardour] Offline export with OSC

by Aurelien

Hello, Several questions in one. I'd like to use OSC (only) to export session in Ardour. I've been able to get the dialog box for exporting session, by using: /ardour/access_action Main/ExportSession But then I've to validate the dialog box, and I'd like something like "assume yes", so that I don't need the GUI (my aim is to run ardour headless), any idea about how I could do that. Second question, is there a way to do a "non-realtime" export, I mean an offline export, like when rendering 3D images, and so on. I don't care about the time it takes, I would like to be able to say that all export process is the same, not depending on who or when it has been launched, and also to consume quite few ressources for that. Thanks a lot. Aurélien -- Aurélien

[LAU] synpad web page

by andy baxter

Hi, I did the talk on 'A position sensing MIDI percussion interface' at LAC at the weekend. A few people asked me afterwards if they could have more information about it, including construction details, so I'm just posting a link to the page on my website about it: http://highfellow.org/synpad There are links here to an instructables.com article about how to build one, the original youtube demo video, and the latest software release which I used for the talk. Hope people find this useful, andy baxter.

Re: [LAU] [Ardour] Offline export with OSC

Fons Adriaensen escribio: >If you export to an integer file format anything above 0dB will >be clipped. > >OTOH, if the export includes resampling then the peaks in the >exported file will be higher than those at the output of the >master strip. The difference will be small in most cases, but >in theory it is unbounded. Better keep a dB or so of headroom. My 2 cents: Keep -0.2db headroom minimum, or for the lazy/cautious: a peak limiter set at -0.2db on the master buss should do the trick. (I'm not a good engineer, so I fall into the second category). -0.2db seems to "hold" it's value better in most software that resamples. Anything higher will almost always end up clipped or limited, in an uncontrolled fashion - as Fons pointed out here, some peaks will invariably be sampled on either side and the software will just pin everything between the samples at 0db. Yuck. I spent an afternoon last year comparing -0.2/-0.1/0.0db max, and I found this to be the case almost every time. Never had a stray peak at -0.2db Shane Richards Producer, Composer, Multi-instrumentalist Josh Music, Cali, Colombia www.josh.com.co www.shanerichardsmusic.com

[LAU] FFADO on LMDE 201012 (aka Squeeze) - possible?

by Artem Vakhitov

Hi, I'm trying to run FFADO on LMDE 201012 which is basically Debian Squeeze. I'm using the the following packaged software versions: FFADO: 2.0.1 libraw1394: 2.0.5 Kernel: 2.6.37 (Liquorix) or 2.6.32 (stock) FFADO dbus server won't start citing no Firewire devices being found. FFADO diagnostics tool tells me that I have the new Firewire stack which is incompatible with FFADO. The thing is though, FFADO website says (http://ffado.org/?q=node/1316) that it should work with the software versions I have: ---Start quote The last weeks have seen a few rumors and lots of questions: Is ffado running with the new firewire stack? The answer is kind of yes. What you need is libraw1394 in version 2.0.5 or higher. And kernel 2.6.32 or higher. Then ffado (both the 2.0 branch and development trunk) should be usable on the new juju stack. Thanks to the team of the kernel-stack and some distributions for stepping up and (mostly) fix the kernel and libraw1394 for this. The changes to ffado where quite minimal. ---End quote So has anyone managed to get FFADO running under LMDE/Squeeze? Regards, Artem Vakhitov

Re: [LAU] [Rosegarden-user] Problem adjusting velocity of several notes in drum matrix (11.02)

by Artem Vakhitov

I've built the latest SVN - works as expected. My only guess is that the misbehavior I observed could be somehow related to checkinstall (I built a .deb of 11.02 with it). Regards, Artem Vakhitov D.

[LAU] Remix Made With Linux

by S C Rigler

Yes, another shameless plug for a remix contest entry, this time it's a remix of "Bring Me Down" by Saigon. The contest link is here (beware, requires flash): http://www.indabamusic.com/submissions/show/55504 I have an mp3, licensed under Creative Commons Attribution-Non-Commercial-No Derivatives 3.0, available here (sorry, I didn't make a patent unencumbered version): http://db.tt/TcusEbd This was made using a vocal stem provided for the contest entry and bits of a backing vocal stem. All done with MixBus, Qtractor, LinuxSampler (for the bass), Qsynth (for the strings), Yoshimi (very briefly for some bass), and Hydrogen (using mostly the "Popsticks" kit from Analog Drums). The acoustic guitars were recorded with a single AT2020 mic and the electrics were recorded direct-in through a Digitech GNX3000. Comments, criticisms and flames are encouraged. Thanks! Steve
