[linux-audio-user] Re: [linux-audio-dev] Concerning libfst, vstserver, and dssi-vst

Yes, in theory, there should be no difference. But try to compile a shared library that links to libwine and use pthread functions, without linking with libpthread. This worked with wine 9.12.2003, but not anylonger. I had to use some crazy hacks on wine to make vstserver compile for about a year ago or something. And later it got worse (unable to compile). The way wine/winemaker constantly changes is so tiresome that I just don't want to touch it anymore. (Perhaps thing have got better now, though.) --

[linux-audio-user] Clone one soundcard's output onto another soundcard's output?

by Kevin Cosgrove

I just know there's some way for me to copy the ch1/ch2 output signals of my Delta 1010 card to the L/R outputs of my Soundblaster. I know that this could be done with my ~/.asoundrc file. I've google, read the docs, lost some hair, lost some sleep, found some more lost hair, and still can't figure it out. Could some ultrakind person please give me a hint? Thanks.... -- Kevin

[linux-audio-user] jack problem

by Georg Holzmann

Hallo! Sorry for just another jack problem - but I have searched the archive, and it's really strange ... My problem: I am able to start jack with qjackctl or jackd. [1] - see example output of qjackctl I want to use PD with jack and the strange thing is, that a few months ago everything worked fine with the same hard- and software. Then I installed a new version of PD and I couldn't connect to jack from PD anymore. So I reinstalled the old version, installed new alsa, jack drivers ... I tried a lot, but I cannot manage it :( My configuration: RME HDSP Multiface, PD 0.38-4, jackd version 0.99.51, QJackCtl version 0.2.15a, debian, kernel 2.6.8 First I thought it is a PD problem, but I also couldn't connect with e.g. jack-rack. I tried different users, settings, ... nothing helped. Maybe someone has an idea?

[linux-audio-user] Re: [ardour-dev] Eek nice hefty crash action...UPDATE

Here's an update. i booted from the gentoo live CD and went and mounted the harddrive and when I go to my home directory (the one the session files for ardour are in *sigh* the one I wrote three songs in since last backup *sigh sigh sigh*) and try to change to my user directory or even ls, I get: ReiserFS: warning: is_leaf: item length seems wrong: *3.5*[3275 337142 0(1) DIR], item_len 0, item_location 500, free_space(entry_count) 1 ReiserFS: hda3: warning: vs-5150: search_by_key: invalid format found in block 21228.

[linux-audio-user] LAC2005: Don't forget to floss^H^H^H^H^Hregister!

by Frank Neumann

Hi all, the 3rd International Linux Audio Conference(*) or "LAC2005" for short is nearing (21-24 April), and if you have not registered for it yet, now would be a good time to do so. It's free, we are not selling your email addresses (honestly!), and it gives you a real bonus: After a short negotiation with ZKM, we agreed that registered participants have free admission to the ZKM Media Museum and the currently running exhibition "Making Things Public". The Media Museum is quite interesting, especially since you can see a real computer monster in live and stunning action there: Recently, they have acquired a fully working Zuse Z22 from a local college. This lady is really worth being seen. Well, I digress. We hope to see many of you next week at the ZKM in Karlsruhe! The LAC2005 Organization Team: Götz Dipper (ZKM) Frank Neumann (*) http://lac.zkm.de

Re: [linux-audio-user] Concerning libfst, vstserver, and dssi-vst

by Kjetil Svalastog Matheussen

Dave Phillips: > > Greetings: > > Users are constantly wrestling with issues surrounding the software > mentioned in the subject line, and I would like to find out what > directions are planned for those projects. Here's what I see now: > > 1. The vstserver project is functionally dead.

Alas, this also means that > his nice vsti, ladspavst, and k_vst~ projects are also unusable. :( > Vstserver does actually works very fine with newer versions of wine, at least the ones I have tried. But for compiling up vstserver, you need the 9.12.2003 version. And worse, the 9.12.2003 version doesn't work with newer versions of Linux, or something like that. (Ie. the workaround is that you first have to install wine 9.12.2003 to be able to compile vstserver, then install a newer versions of wine. The plugins will then use the newest version of wine). I think there exist a patch or something for the 9.12.2003 version of wine to make it compile with newer versions of linux (not sure which part). If anyone has such a patch, it would be nice if someone sent it to me. I'm still on Redhat 8 myself, so I don't know what the problem is exactly. > 3.

It should not be much work to make vsti, ladspavst and k_vst~ work with dssi-vst instead of vstserver.

The fst-way and the vstserver/dssi-vst way. Both "ways" are needed. One of them is very fast, but hard to set up (fst). The other one is safer and slower, and a little bit less hard to set up. Problem is, that the releases most probably does now depend on a spesific version of wine, or will depend on a spesific version of wine in the future. It would be nice if the three projects (or at least fst and dssi-vst) was coordinated to use only _one_ version of wine, and that this version of wine is downloaded from one place, for example a sourceforge project place. But for this to happen, some person needs to step up, set up a sourceforge account, do some coding, coordinate the coders, release things, do some work. It might not seem like Thorben, Paul, Chris or myself is the right person right now. Perhaps there is some coder with some free time that wants to do this stuff? --

[linux-audio-user] Audiotrak Maya EX5 playback problem

by Martin Rehak

Hello, I have $(SUBJ) and have following problem. At certain conditions, there occur clicks in the output of the soundcard. It doesn't matter on what application I use for playback. The result is same for aplay, xmms. It seems the number of 'clicks', which disturbes the playback repeats in certain frequency and probability at which it occur is greater with rising dynamics of sound source. For sure i tried to play the same sound source under MS Win and realized, that there is no such problem. --<cut>-- raven@edmund:~> uname -a Linux edmund 2.6.11-edmund #1 Tue Mar 15 18:53:04 CET 2005 i686 unknown unknown GNU/Linux raven@edmund:~> cat /etc/slackware-version Slackware 10.1.0 raven@edmund:~> ls /var/log/packages/ | grep alsa-utils alsa-utils-1.0.8-i486-1 raven@edmund:~> cat .asoundrc --<cut>-- Kernel is vanilla one with no patches with PREEMPT disabled. Complete config file can be seen at http://213.168.184.214/~raven/tmp/edmund-config I know, that this sound card cannot sampling rate 44100Hz but only 48000Hz. This is the reason 'something' (perhaps alsalib) must do upsample from 44100Hz to 48000Hz. Could be this the cause? How can I get rid of it? Thanks a lot for answer Martin Rehak

by Jorge Salgueiro

I would like to know if there is any way to be able to seq notes singing. That is a program that transforms what you are singing in notes so that they could enter a synt. and well, you could do music with the speed and ease of thought... if reatime better.. if "jack enable" bettttter yes i am a lasy non musician.
