All, Since we'll be buying a laptop for our oldest son's birthday I though heck, perhaps I can piggyback on it when he's not using it and maybe have an easy-to-use, light, way of recording sketches and improvs on some weekends mornings in the living room. And hopefully being able to take some of that to the main workstation's Ardour setup for further development. Sketches would be done using an accoustic guitar and a small MIDI keyboard (using fluidsythn, zyn and perhaps linux sampler). So here I have a few questions. 1) What is the most easiest-to-setup MIDI/audio interface for a laptop ? Fedora 11 will be installed on the laptop. The laptop will probably be a dual core with 2 to 4 GB of RAM and some 300 GB hard disk. The screen will probably 16". This will not be a top-of-the-line laptop. 2) What are the options to record accoustic guitar ? Are a traditional boom and mic the only way w/o having a built-in pickup installed in the guitar ? 3) What would be the very smallest MIDI keyboard available ? I have an Axiom 25 although something even smaller would be nice. 4) What are the options to hearing stuff ? So far I think that the laptop's speakers, processed by Jamin could be OK. Are there any small/tiny external speakers for this kind of application ? 5) On the software side, there should be no problems in running any audio app on modern laptops ? Or are there distro/laptop incompatibilities issues that would prevent jack from running for instance ? Finally, if there are any web sites dedicated to Linux laptop audio recording, please let me know. Thanks for your suggestions/ideas/comments ! Cheers.

[ANN] QjackCtl 0.3.5 slipped away!

Change-log: - Late support for UTF-8 encoded client/port names. - Allow only one single patchbay connection to or from an exclusive socket (mitigating bug #2859119). - Automatic crash-dump reports, debugger stack-traces (gdb), back-traces, whatever, are being introduced as a brand new configure option (--enable-stacktrace) and default enabled on debug build targets (--enable-debug). - Probable fix on the audio connections with regard to client/port (re)name changes (an ancient bug reported by Fons Adriaensen). - Portaudio device selector is now available (after a patch handed by Torben Hohn and Stephane Letz). - A couple of primitive D-Bus interface slots have been introduced, giving the option to start/stop the jackd server from the system bus eg. via dbus-send --system / org.rncbc.qjackctl.start (.stop), (a nice addition supplied by Robin Gareus, thanks). - New command line option (-a, --active-patchbay=[path]) to specify and activate a given patchbay definition file (a simple patch sent by John Schneiderman, thanks). - Added one significant digit to DSP Load percentage status display. - Tentative support for netjack (slave) by adding the "net" driver to the existing backend driver options on the Setup/Settings section. - Converted obsolete QMessageBox forms to standard buttons. - New patchbay snapshot now raises the dirty flag and allows for the immediate salvage of patchbay definition profile. - Conditional build for JACK port aliases support (JACK >= 0.109.2). - Alternate icon sizes other than default 16x16, are now effective to the Connections widget (Setup/Dislay/Connections Window/Icon size).

Is there > a DSSI version available? Not yet. 0.12.0 only supports ALSA MIDI and JACK audio. The code needs to be ripped apart and put back together again for 0.13.x, and then it's a matter of supporting the other audio/MIDI frameworks one by one. LASH, LADI, JACK MIDI, OSC, DSSI, and LV2 are all on the todo list. I wanted to get a stable release out that just plain works before this undertaking. > Ralf > > -- > Taking a look at the screenshots reminds me to ask something OT: Does anybody > know an insiders' tip were to get CME microchips for old faithful analog > synth by a fair price? Define "fair"... price on these NOS chips started going up years ago. I paid $60 for a wave-gen chip for a Juno-106 about five years ago, and thought that was fair at the time. Chips for other synths can range from a little less to a lot more. Check ebay, you might get lucky. Cheers, --ww

need some advice before upgrading JACK

by Dave Phillips

Greetings, 64 Studio 2.1 is a wonderfully stable and reliable system, one I've used profitably for quite a long time now. Alas, it's definitely out-of-date, and its version of JACK is the lamentable 0.109.2, and it's causing some problems with AVSynthesis that I'd like to finally resolve by upgrading JACK. I have 64 Studio 3.0 beta on my laptop, but I don't plan to upgrade the production machine until 3.0 reaches a stable public release. Meanwhile I'll be pleased if I can safely upgrade some of its components. Here's the question: I've successfully compiled JACK 0.116.2 and JACK2 1.9.3, so in the opinions of my fellow LAUyers, which is the better choice for this system ? If I move to JACK2 will I need to recompile my JACK-savvy apps ? (That's not usually a problem.) I await the dawn. :) Best, dp

CC licensed music repositories

by Ismael Valladolid Torres

Sorry in advance for crossposting. I am creating my own podcasts. However I am concerned about how the songs and audio I'm using as background of my speeches is copyrighted. So I wonder which repositories of CC licensed music are out there, so I can download songs and use them freely as backgroud music in my podcasts complying to their license simply by attributing. Ambient style suits perfectly, but other styles could also be useful for me. Any ideas useful so thanks in advance.

I don't know how Craig (the soundman) has the recording system arranged, i.e. I have no idea what he's doing with EQ and other settings. However, the place is a coffee shop with a capacity of about ~60 customers, and Craig always favors the voice. He's been running instruments through the board too, but the sound out front is always well-balanced and never too loud. Coffee Amici's Web site has some nice photos of the place, you can get some idea of the environment from the shots: http://www.coffeeamici.com > Apart from that, "as usual from you" this is solid, well-done blues - nice > music that has just found its way into my $HOME/media/ogg/DavePhillips/ > archive.

Jostein wrote: > OT: Where in this group did someone mention that Dave Phillips was a little > disappointed (?) about low feedback when linking music on LAU? A little clarification. Garry Ogle mentioned a statement I made regarding his extended commentary on a recent piece. Here's the relevant exchange: At the end of his comments Garry wrote: > > My apologies for wittering on to no great end. > I replied: > No apology necessary. I like reading such commentary, but alas, I don't get much of it. Feel free to ramble on about whatever, whenever. The reference was specific to the piece we were discussing and to Garry's comments on it. For the record, I post notices about my music at various places, and I'm very happy with any & all response it generates. I shouldn't bitch about missing in-depth commentary, I'm certainly not always as effusive as I'd like to be wrt the music I hear from friends and colleagues, on LAU and elsewhere. Alas, time is precious, and there's always pressing work. Best, dp

Alsa or pulseaudio?

by Jennifer

Hi. I am trying to modify a version of easy peasy Linux so that it is more accessible on my netbook (an Acer Aspire1). Easy peasy is a derivative of Ubuntu and I am currently having problems with pulse audio. When using pulseaudio speech was a little laggy (even after switching to using speech-dispatcher). I also had some orca crashes, who's source is still unknown to me, though I have been informed it is probably because I am using a netbook. When I use Alsa I still have the odd orca crash but this is usually easy to resolve simply by restarting orca, or killing and restarting speech-dispatcher. The problem is I have no system sounds and I get an Alsa error when trying to log in to Skype through the terminal, some problem with bluetooth something. I can paste the error later if it is of any use/reference. I am now using Alsa but can't seem to get multi channel sounds, I.E speech and/or system sounds, I only have speech. Any help fixing these issues and suggestions for alternative configurations/audio systems would be appreciated.

Me too ! New music :)

by Svend-Erik Kjær Madsen

Hi list I've just finished a collab with an awesome lyricist from USA "Rockangel", she wrote a beautiful lyric, and to that lyric I wrote music and played it all together. For the project I've used Ardour as recorder, Electric YamahaDTXplorer drums, ZynAddSubFX bells, organ and bass, my SG over a TC Nova system direct in, and a AKG C 3000B Mic for my vocals and the acoustic guitar, my sound card is RME Multiface. The song 320 Kb version in mp3: http://semcity.sv-e.dk/collab/SimpleLoveFinalRAW.mp3 It's kinda a pop/rock tune, lyrics and other details about the song can be read here: http://www.soundclick.com/bands/page_songInfo.cfm?bandID=456274&songID=8056… Constructive critics is welcome. Thanks for reading. /Sv-e
