[linux-audio-user] what version of alsa to use with maudio quattro

by Brian Redfern

I've been having some wierd problems with the stock drivers in CCRMA with the quattro, I get sound in just fine, but no sound out, when I switch it correctly its just distorted hiss, what version of alsa are people using to get both input and output working from their quattro, and can you get full duplex, and if you guys don't mine sharing how you did it, I'd appreciate it.

[linux-audio-user] [ANN] lakai-0.1

by Frank Neumann

"At last", Roboff says, "I have it." - from "Mask Of The Sun" Hi LAU'ers, I'm happy to announce the first release (0.1) of lakai, a small tool package that allows to exchange data (samples, programs) between a Linux PC and an Akai sampler (S2000 tested; other 2xxx/3xxx models might work or not) over SCSI. This permits "complete backup" and "complete restore" of the sampler RAM contents. Availability: http://sourceforge.net/projects/lakai (the web page was not updated yet) Right now, everything is just shell-based, no GUI yet, and the tools are rather rudimentary, the source is ugly and sprinkled with TODOs and printf's etc. pp., but at least it WorksForMe(tm). I welcome comments, success stories and bug reports, but my answers might take a while :-). All further info is in the archive in the README - read it, it took me a while to put it together. This stuff comes rather late - in fact, I created this sourceforge project more than 4 years ago, and I have only been working on it very rarely for a long time (and it's even quite small). The S2xxx model samplers are only available second-hand today, and software-based samplers (like http://www.linuxsampler.org) are already on the way. I am still very proud that I finally got this baby out of the door. Ha! :-). Enjoy, Frank

[linux-audio-user] ams, jackd & X as root? on debian

by Eric Dantan Rzewnicki

hello, I have jack installed and working now. So, now I'm trying to get AlsaModularSynth compiled and running. Has anyone else accomplished this in debian stable (woody)? I installed libqt3-mt (along w/everything it depended upon), fftw-dev, fftw2, sfftw-dev, sfftw2 and ladspa-sdk to get ladspa.h. I've tried to edit the top of make_ams to agree with the location of the qt3 libs, bin and include directories on my system as best as I could figure ... but I'm not sure I got it right: QT_LIB_DIR=/usr/lib/qt3/plugins/styles QT_BIN_DIR=/usr/share/qt/bin QT_INCLUDE_DIR=/usr/include/qt it seems to compile OK when I do: make -f make_ams though there are a lot of warnings about comparing signed to unsigned and other warnings that flew by. Are these benign? Anyway. I end up with an executable ams. When I run ./ams I get this: ./ams: error while loading shared libraries: libjack.so.0: cannot open shared object file: No such file or directory I have that in /usr/local/lib/libjack.so.0 so creating this link appears to help: box1:/usr/lib# ln -s /usr/local/lib/libjack.so.0 libjack.so.0 Is that the correct sollution? but, now: box1:/home/eric/audio_code/ams-1.5.5# ./ams ams: cannot connect to X server I assume this is because X is running as me (eric) and not as root. I'll try getting out of X and starting it as root as soon as I finish writing this message. But, is there a way to let root connect to the X server that's running as eric? I was sort of ok (well, not really, but I'm giving it a try) with the idea of running jackd and its clients as root ... but, running X as root, too? that makes me more nervous, somehow... maybe I shouldn't be nervous about that ... I'm not sure. anyway. i'll give it a shot with a root X session. I'm thinking that maybe I should patch and recompile the kernel and recompile jack to enable capabilities so I don't have to run as root. Do those of you running jackd as root also run your X session as root? Thanks for listening, Eric Rz. PS If all of this has been covered before and my questions are annoying you, feel free to send me to the archives. I try to follow jackit-devel, but most of it seemed to go over my head before I actually started to try it. So, re-reading the past couple months would probably do me some good now that I have the real thing in front of me. -edrz

[linux-audio-user] cabling question: crosstalk between audio and cat5 ethernet?

by Joern Nettingsmeier

hi everyone! we are moving houses in a month, and i'm planning to install some decent cabling thoughout our new flat. begone, ye maze of twisty little cables all alike :) the idea is to run an eight-way symmetric audio multicore (shielded pairs and an outer foil shield as well) along with 4x cat5 s/stp cables carrying 10/100/1000baseTX ethernet in the same cable duct over a length of about 15-20 meters. will this lead to problems in the audio signal? my naive hope is that since all garbage radiating from the ethernet will be well outside the audible range it might be ok. but then there's always the chance of something demodulating it into the 20-20k range... does anyone here have experience with such a setup? any hints, success and/or horror stories welcome. jörn -- "I never use EQ, never, never, never.

[linux-audio-user] RME Cardbus + multiface

by Vincent Touquet

Hi, Anyone in here using a RME cardbus card in a laptop ? I'm considering going that route and it would be nice to be able to use that interface in Linux. I was planning to go the powerbook way, but as I have to develop for XP and Linux in the first place, I will probably go for a Thinkpad (who seem to have great battery life). Any info is appreciated, vini PS: I noticed that the Multiface is listed as supported on the ALSA site, but I don't know if that means the cardbus card too, or only the PCI card + multiface.

[linux-audio-user] DeMuDi-Creature Re:[ports|quests]

by tim hall

Andrea, Free, Damien et al. All the creature[0] reports I still have open are packages that still don't work on my machine. I just felt I should make that clear. However, I have been altering the priorities to try to indicate whether I consider them important (to me as opposed to the distro generally). Thus the low priorities are things I've noticed, but can work around. Some like the tk707 psting relate to DeMuDi-1.0 versions and can be safely closed. If you do happen to close an item which was important to me that will simply prompt me to get in touch to clarify. The 'important' issues for me are with the Jack'd apps. I'd particularly like to sort out MusE, Hydrogen and Jamin so I can get making music. I understand that experimenting with Jack currently involves facing frequent crashes, however, an application does need to start up, connect with Jackd and preferably open a file or two before it can crash the system in a satisfactory manner. Despite my successes at repeatedly and logically breaking things, It's not always so easy to find or record any meaningful output and this makes it difficult to proceed towards a solution. From recent discussions I take solace in the knowledge that I am not alone and that this is in fact the day-to-day reality of most software developers, who long for the day they can actually sit down and use the product without having to file another bug report. I do sympathise. Damien says he thinks he's fixed the creature[0] on Jamin. How do I find the bugfixed package so I can verify that it works on my system? Thanks for all the great work you're doing. If you can think of any ways my input can be made more useful, please don't hesitate to let me know, like a Package-Breaking-HOWTO or X-Crashing-HOWTO, these would be welcomed. *grins* tim hall [0] "That's not a bug, it's an Undocumented Creature" - Terry Pratchett - Discworld2 -

[linux-audio-user] Should I Bother Learning Csound?

by Peter Groves

Hi Everyone, I'm a long time musician and am starting to get into electronic/computer music (actual synthesis, up to now I've just been concerned with recording physical instruments). I've been looking around at all the complicated things I could learn and have been considering csound. It seems like it would be the last thing I'd ever need to learn. I also like that it's based on text files (I'm a programmer by day, and prefer to do as much as possible in simple tools I already understand). I'm not sure I would use all of it's features, though. Here's what I think I'd like to use it for: -Effects- I was thinking it would be nice to use csound filters as LADSPA plugins. Then I recently saw that someone had started a project doing just that. Has anyone used this? All that was available was a tarball of the source, with little documentation. Can you use csound 'effects' directly, or do you have to write a complicated wrapper to have a particular effect appear as a proper plugin? -Instruments- Can csound instruments be used as midi instruments or maybe soundfonts? I really don't know how midi, midi instruments, soundfonts, etc work, or what the differences are, so I don't know if this is even a reasonable question. So that's it, I guess. I'd rather do the actual arranging and composing (of synthesized parts) in something like muse or rosegarden, and be able to apply effects to 'real' instruments through jack-rack (or something similar). I think that would be much more flexible than doing it in csound, as it would be easier, for instance, to change the tempo of all the tracks of a song at once. Thanks for any opinions, Peter

There was a 0.35 version that had been patched to support non-interleaved mode IIRC. Maybe you can try to use the card through the plug layer, but performance will be suboptimal. Thomas

Check with "fuser /dev/snd/pcmC0D0c" or similar. With Pd however a lot of people have problems using the RME cards directly. You may be luckier if you use Pd over Jack. Otherwise try to not use Pd's default device hw:0 when starting Pd but maybe use plughw:0 first or define a device in your ~/.asoundrc, that matches your favourite setup. Pd 0.37.1test6 now has the "-alsaadd" option to let you specify arbitrary PCM names. ciao -- Frank Barknecht _ ______footils.org__
