[linux-audio-user] Needs Drums

by Folderol

Would anyone like to add a fairly aggressive drum track to something I've been working on? It's at http://www.musically.me.uk/music/Running_Through_The_Night.ogg It's all done with Rosegarden and ZynAddSubFX so I can easily supply the 'construction files' to anyone who is interested. -- Will J G

[linux-audio-user] Conexant laptop sound woes

by John Mulholland

Hello again all, It has been too long, since I last posted. I hope all is happy and well, and hopefull I'll get to see many of you again at FAVE this year. Anyway, I do have some LAU business, and I really hope someone can help me here because I am at a total loss. A few months ago I bought a laptop for the wife. It is a Packard Bell Easynote A8550 (1). They are selling these fairly cheaply at the moment and it looked ideal. Unfortunately getting it to make a sound in Linux has caused me no end of headaches. It appears that the problem relates to the Conexant chipset(2). From what I can gather Conexant have not released the data sheet to the ALSA crowd. And so, I suffer in silence. I am not too sure about though, as I am not a massively technical person. This really frustrates me because it seems that all the other PB machines have working sound!! Does anyone know if Conexant regularly do this sort of thing? and how often do they release data sheets? I fear that I may be waiting in vain.FWIW this is all in Edgy Eft. All help, comments and advice much appreciated! Cheers John

Re: [linux-audio-user] VST support in Ardour2 beta.

by Mathias Friman

I had to have the wine-development files installed as well, and the vstsdk2.3-directory had to be in /libs/fst, other than that it worked. However, I have an error message when I start ardourvst, which is: Gtk-Message: /usr/local/etc/ardour2/ardour2_ui.rc:83: failed to retrieve property `GtkWidget::cursor-color' of type `GdkColor' from rc file value "((GString*) 0x77d1df40)" of type `GString' But apart from that, everything seems to work just fine. :) Tack så mycket! ----Original Message----- From: Peder Hedlund peder(a)musikhuset.org Date: Wed, 11 Oct 2006 17:42:43 +0200 To: A list for linux audio users linux-audio-user(a)music.columbia.edu Subject: Re: [linux-audio-user] VST support in Ardour2 beta. > How do I compile VST-support into Ardour2 beta? > VST=yes, but after that? > Where should i put the VST SDK 2.3 directory? Make sure you have wine installed. (I tried with the latest). You have to copy the vstsdk2.3/source/common/*.h to /usr/include/vst (I think this is a bug. You shouldn't have to be root to install ardour) Put the vstsdk2.3 directory in the lib dir of the ardour source tree, IIRC. (scons will complain and tell you where it expects it if that's the wrong place) Run 'scons VST=yes' (and other options if needed) and 'scons install' assuming the compile succeeds. Put some VST-dll's , like these : http://www.kjaerhusaudio.com/classic-series.php, in a "vst" directory in your home dir and make a symbolic link to that from /usr/local/lib (I think there's a varaiable you can use to point to your directory as well) Start ardour, display the mixer, right-click on the effect box, select "New plugin" and you should see a VST tab as well as the LADSPA tab. - Peder

[linux-audio-user] [Music] a samba

by Steve D

A samba I'm working on-- http://www.xscd.com/pub/music/audio/ogg/stephen-doonan_samba-1.ogg For this piece, I decided to do all the recording in Rosegarden. I first recorded a scratch (to throw away later) piano part to the metronome, to get the (minimal) arrangement down to guide me, then I recorded the percussion track, then the bass track and finally the piano track, all in MIDI. Then I used Rosegarden's MIDI mixer to balance the sound levels (to where they sounded good to me anyway :-), and had Rosegarden play back the MIDI to my external hardware tone generator (A Roland FantomXR is what I used for this recording), and recorded the resultant audio through an M-Audio Delta 1010 sound card back into the computer, through jack (qjackctl) and back into an audio track in Rosegarden. Then I exported the audo track as a .wav file, quit Rosegarden, opened the file in Audacity (I love Ardour and Jamin, but I wanted to limit myself this time, and Audacity is a fine application in its own right) and normalized the audio, then exported it as an OGG Vorbis file. I guess I could have just used the command-line programs normalize and oggenc instead. Then I tagged the OGG with easytag (nice program), with the Creative Commons attribution share-alike license: http://creativecommons.org/licenses/by-sa/2.5/ It's so much fun to create music, and so much fun to use the truly great tools available in Linux now. I wish I knew some local musicians (a drummer, bass player and maybe another instrumentalist like a guitarist or sax player, to form a small trio or quartet), but I don't (I live in a very rural area with not too many musicians to begin with and no way to make a living at it), so I just play all the parts myself as best I can.

[linux-audio-user] freedb track info fetcher?

by Mario Lang

Hi. Do we have any script that would: * For a directory, calculate CDDB id, fetch from freedb, tag files, rename files. * If no freedb entry, check musicbrainz There are a lot of CDDB based tools for linux, but they all seem to depend on the physical disk being in the cdrom drive. Those that seem to support cddb id caluclation, all are GUI only. I'd like to have a command-line tool, for batch processing. -- CYa, Mario | Debian Developer <URL:http://debian.org/> .''`. | Get my public key via finger mlang(a)db.debian.org : :' : | 1024D/7FC1A0854909BCCDBE6C102DDFFC022A6B113E44 `. `' `-

[linux-audio-user] Setting IRQ on intel8x0-card

by Mathias Friman

Hi list. I have a question regarding IRQ-assignment for an on-board card identified as an Intel 82801DB-ICH4. It is a crappy card, I know, and you probably ask yourselves why on earth I would want to put any effort in configuring such sub-standard equipment. The question, fortunately, is a bit broader than that. I'm writing some swedish docs on how to set up a Linux-system as a DAW, and see the need to do it thoroughly. :) As of now the card shares IRQ with the eth0-card, which isn't super if one is to set RT-prio 99 on it. Is there a simple way in setting a specific IRQ without the need for a super-BIOS that does it for you? Since I have a laptop the option of shuffling the PCI-cards isn't really viable. :) I think I remember from my early days of kernel-hacking that it is possible to set IRQ with modprobe options, but it was a while ago. I searched through the kernel tree in the /sound/pci/intel_8x0.c file to no avail. Any feedback is welcome, with the sole exception of "Why?" ;) Regards, Mathias
