[linux-audio-user] Problems with VST under linux

by axiom＠sphereserver.sm

Hi all. I'm trying to get VST plugins run under linux (a RH9 with Planet CCRMA, kernel 2.4.22-6.ll.rh90). I've followed those steps: - downloaded wine 20031118 - downloaded vstserver-0.2.8 (ladspavst too) - i've installed wine simply untar it, then ./wineinstall - i've compiled vstserver and ladspavst following their instructions - i've correctly set VST_PATH (if i do "cd $VST_PATH" it brings me to correct folder) Now, when I run vstserver, then open a sound application (Audacity, in example), i'll get this error: VSTSERVER/main: Vstserver 0.2.8 started. Waiting for requests. VSTSERVER/main: Going to try to start vst plugin "DFX Transverb.dll". wine: Unhandled exception (thread 0009), starting debugger... WineDbg starting on pid 8 Loaded debug information from ELF 'wine' ((nil)) No debug information in 32bit DLL 'F:\vstserver-0.2.8\vstservant' (0x40730000) No debug information in 32bit DLL 'NTDLL.DLL' (0x401c0000) No debug information in 32bit DLL 'KERNEL32.DLL' (0x40440000) Unhandled exception: page fault on read access to 0x409ffd80 in 32-bit code (0x4000c239). In 32-bit mode. 0x4000c239 (_end+0x400a40d): movl 0x0(%eax),%eax Wine-dbg>WineDbg terminated on pid 8 i've even tried with a wine version suggested by INSTALL of vstserver, but when it try to do last configuration step (next make, when it tries to write the first registry entries), wine going in a debug loop and no programs starts, even regedit. Now, i'm totally stuck. Sacrifing my dog in a full moon night and sell my soul to Stallman never gave me better results. Perhaps you? :) Thx in advance, Luca

[linux-audio-user] Getting Quattro to work with other soundcard

by Adam King

Hi All, I'm trying to get my M-Audio Quattro to work as a second device in addition to my SoundBlaster Live! I'm using ALSA 0.9.6 and have managed to get them both to work. I am using Patrick Shirkey's asound.conf, however i can only seem to use the quattro as devices quattro1 and quattro2. Jack fails with any other settings that are defined in asound.conf. I've compiled Patrick's qinit program but it segfaults. My asound.conf is: # quattro1 is pcm0 which has a maximum sample rate of 44100 and 16 bit stereo pcm.quattro1 { type hw card 0 device 0 } ctl.quattro1 { type hw card 0 } # quattro2 is pcm1 which has a maximum sample rate of 96000 and 24 bit stereo pcm.quattro2 { type hw card 0 device 1 } ctl.quattro2 { type hw card 0 } # quattro2 is pcm2 which has a maximum sample rate of 96000 and 24 bit stereo pcm.quattro3 { type hw card 0 device 2 } ctl.quattro3 { type hw card 0 } #---- # # compose 4 channels from two channel x two devices, hw:2,1 and hw:2,2 # assuming that hw:2,1 and hw:2,2 give the same condition, 24_3LE/96k # pcm.quattro { type multi; slaves.a.pcm "hw:0,1"; slaves.a.channels 2; slaves.b.pcm "hw:0,2"; slaves.b.channels 2; bindings.0.slave a; bindings.0.channel 0; bindings.1.slave a; bindings.1.channel 1; bindings.2.slave b; bindings.2.channel 0; bindings.3.slave b; bindings.3.channel 1; } ctl.quattro { type hw; card 0; } # # remap 4 channels as interleaved. # use plug instead of route here, since 24_3LE is unlikely supported by # applications. # # arecord -r 44100 -c 4 -f s16_le -D q4 -d 5 /home/xxx/q4.wav pcm.q4 { type plug; slave.pcm "quattro"; ttable.0.0 1; ttable.1.1 1; ttable.2.2 1; ttable.3.3 1; } ctl.q4 { type hw; card 0; } # # Use route plugin for applications that do support 24_3LE # This lowers latency which the plug plugin introduces due to resampling. # # arecord -r 44100 -c 4 -f s16_le -D q41 -d 5 /home/xxx/q41.wav pcm.q41 { type route; slave.pcm "quattro"; ttable.0.0 1; ttable.1.1 1; ttable.2.2 1; ttable.3.3 1; } ctl.q41 { type hw; card 0; } #---- pcm.emu10k1 { type hw card 1 } ctl.emu10k1 { type hw card 1 } and my modules.conf is: # START alias char-major-116 snd alias char-major-14 soundcore # Quattro alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss # SBLive alias sound-slot-1 snd-card-1 alias sound-service-1-0 snd-mixer-oss alias sound-service-1-3 snd-pcm-oss alias sound-service-1-12 snd-pcm-oss alias snd-card-0 snd-usb-audio options enable=1 alias snd-card-1 snd-emu10k1 options snd-emu10k1 extin=0x3fc3 extout=0x1fff enable_ir=1 Is there anything I am obviously doing wrong. Any help would be appreciated. Cheers, Adam

[linux-audio-user] Mozilla configuration? (mp3 question)

by Mark Knecht

Why should this happen? Looking at Ico's new RTMix, I follow the links here http://meowing.ccm.uc.edu/~ico/RTMix-doc/5.html to listen to some samples. The first sample takes me to a page http://www.ohiolink.edu/etd/view.cgi?ucin984494016 with an mp3 link in the upper right. I click on that link and I'm forced to download the mp3. However, the second sample loads the mp3 in Mozilla using gxine and plays in the browser. Why should this happen? Why shouldn't they both play in Mozilla? Thanks, Mark P.S. - I like the music Ico

[linux-audio-user] ice1712 dshare asoundrc

by Garett Shulman

I would really like to do hardware mixing since my card should support it. I have been hacking away trying to google and decypher the plugin docs and have created the following asoundrc. However, when I try to run a second instance of fluidsynth on 44_2 I get the following error: ALSA lib pcm_dshare.c:800:(snd_pcm_dshare_open) destination channel specified in bindings is alread used. I'm not sure what I'm doing wrong. Is alsa simply not capable of taking advantage of the ice1712 hardware mixer? Here is the asoundrc I have so far. pcm.44_dshare { type dshare ipc_key 42892323 ipc_key_add_uid yes slave { pcm "hw:0,0" period_time 0 period_size 70 periods 24 buffer_size 1024 channels 10 } bindings { 0 0 1 1 2 2 3 3 } } pcm.44_1 { type plug ttable.0.0 1 ttable.0.1 1 slave.pcm 44_dshare } pcm.44_2 { type plug ttable.0.2 1 ttable.0.3 1 slave.pcm 44_dshare }

[linux-audio-user] ANN: RTMix 0.75 released

by Ivica Bukvic

Greetings! It's my pleasure to announce immediate availability of RTMix version 0.75. RTMix is an interactive multimedia art performance, composition, and coaching interface capable of triggering various DSP applications and/or processes concurrently, as well as offering a tight coordination between computer(s) and live performers. It can also trigger real-time events utilizing MIDI and OSC protocols, and can be in theory networked from a single client with up to 1000 other RTMix clients (personally neither have I had the opportunity to try this and besides the network latency would probably get the best of it anyways). For more info on what it is, what it does, and how it does it, please see the online docs: http://meowing.ccm.uc.edu/~ico/RTMix-doc/ Changelog: *Minor bug fixes in scripting language. *Ability to connect directly to /dev/sequencer (needs to be tested -- any help in bug reporting is greatly appreciated!). This should theoretically enable users to have theoretically infinite number of MIDI devices hooked up to RTMix (using ALSA's aconnect). *UI improvements (mostly "eye-candy"). *New LED icons for improved visibility. *Improved functionality of the Console. *Full documentation included in the distribution (just in case someone missed this one from before :-). *New application icons (16x16 to 192x192). *Smaller tarball. *This is the last version before the milestone 0.8 release with that will sport a completely revamped UI and many new features. RTMix has so far been featured at ICMC 2002 conference (Sweden), SEAMUS 2003 conference (US), in the "Organised Sound" magazine (December 2002), and has been used in several of my works whose recordings are available on my website. If you happened to use RTMix in your work, I would love to hear in what ways you got to utilize its features, as well as how can I make the application better. Thanks! The tarball is available for immediate download from: http://meowing.ccm.uc.edu/~ico/rtmix-latest.tar.gz (4.07MB) For more info, please visit my website and/or the online documentation (provided above). Best wishes, Ivica Ico Bukvic, composer & multimedia sculptor http://meowing.ccm.uc.edu/~ico

[linux-audio-user] newbie: sipmle recording software request

by Matthias Knelangen

hi, sorry if this has already been widely discussed, it looked through the archives but couldn't find anything. Ok, I'd like to write a live-streaming to my hard disk. So I need a simple sound-recorder for I think there's no means to directly save an mp3-stream to the disk. could anyone point me towards a simple recorder? thanks matthias -- Matthias Knelangen matthias(a)knelangen.de ---------------------------------------------- Outside of a dog, a book's a man's best friend.

[linux-audio-user] Linux Audio Article in CM Special

by Natalia Rakowski

Hello - Just wanted to let everyone know that an article that I wrote about Linux Audio is in the current Special Issue of Computer Music magazine. It is Special Issue #6 - Get Professional. It came out in the U.K. on the 30th of October and should be making its way to the U.S. and other destinations soon. I would love to get feedback about this article directly at: soulsource(a)cox.net. I am doing my best to try to convince more music tech magazines to publish articles about Linux as a viable music OS -- so if you liked the article, please try to e-mail a note to the magazine saying so... Thanks everyone! -- N

Hello, I got an kt400 motherboard and lspci lists the following audiodevice: 00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235 AC97 Audio Controller (rev 50) The only output port that works is the green one (in the middle), the pink one to record works fine. I wan't to connect my stereo system at the same time I have headphones. How do I do this? That is, how do I enable my blue port? I am using linux-2.6.0-test8 with the alsadrivers from that kernel. -- Lean Fuglsang <lean(a)omnia.dk>

[linux-audio-user] ANNOUNCE: QSynth 0.0.1 - Qt interface to fluidsynth

by Chris Cannam

[This has been announced on LAA already, but I gather crossposts are expected.] We'd like to announce the first alpha release of QSynth, an attractive Qt front-end to fluidsynth. QSynth is brought to you by Rui Nuno Capela, developer of qjackctl, together with Richard Bown and Chris Cannam of the Rosegarden team. QSynth provides a simple front and configuration interface to the fluidsynth software synthesiser to allow persistent storage of fluidsynth configuration (and soundfonts) as well as providing visual feedback and front panel controls for software synthesiser parameters. QSynth can be used either as a standalone player or in conjunction with any compatible sequencers. For more details, screenshots, mailing list details and to download the source code please visit: http://qsynth.sourceforge.net Requirements are Qt3.1.1 and libfluidsynth. Please let us know how you get on with it! Chris

Re: [linux-audio-user] Silent Linux box article released

by Daniel James

> I wonder why > you did not develop the laptop idea further. They usually start > out much quieter than usual desktops. Well, apart from the fact that laptops have relatively poor ergonomics and are difficult to repair and upgrade, they are an expensive solution if you don't need portability. Also, most of my audio hardware requires a PCI slot. But the main reason was that I set out to build a completely silent machine, and because of the tightly packed electronics in a laptop a fan is typically required. These are usually very small fans producing a high pitched whine when the CPU is under load, which is exactly the kind of noise I was trying to avoid. Cheers Daniel
