[linux-audio-dev] Linux/Alsa Tascam US-122 Issues

by Antonio Willy Malara

hello everybody! i've finally got an usb-audio card for my linux audio madness, i've taken a tascam us122, beacuse of the good support it has, infact i was able to use it, i've not tested it extensively because i was moving and my laptop had a desperate need of a reinstalling :P i've reinstalled this ibook with a net-installed debian sid and the first thing i've done was compiling the same alsa and kernel versions, linux vanilla 2.6.8.1 and alsa-driver 1.0.6a, alsa-lib 1.0.6 but all alsa wont work... with the internal powermac audio card (which was working) i got a undefined referece, in compile time (but not fatal, since the module is compiled) and in inserting time: Zeryn:/home/willy# modprobe snd-powermac snd_powermac: Unknown symbol num_controls Zeryn:/home/willy# but i can live without it, i have the oss module and i plan to not use it anymore, because the tascam card will be conencted to everything in my setup, but the strangest things happened when i tried to plug the usb-usx2y module: a variety of freezes, kernel panics, oops, so i've tried to compile different versions of alsa and kernel, i've tried combinations of: linux 2.4.27, 2.6.8, 2.6.7, 2.6.9-rc2, 2.6.9-rc2-bk9 alsa 1.0.6, 1.0.6a, 1.0.7rc1, alsa-cvs (alsa cvs was broken) now i got the same error over and over again, the hotplug scrits are loading the firmware, the module is correctly loaded and the card is powering up well and the usb led keeps to stay on, but, when i try to launch jack or an audio application i got some messages regarding "sequence errors" and i have to kill the application via ctrl-c, if i restart the application i have a freeze (no kernel panics or such) this is the kernel log from kernel module loading to the freeze --- Sep 26 05:34:27 (none) kernel: usbcore: registered new driver snd-usb- usx2y Sep 26 05:34:37 (none) kernel: ohci_hcd 0001:01:18.0: wakeup Sep 26 05:34:37 (none) kernel: usb 1-1: new full speed USB device using address 2 Sep 26 05:34:38 (none) kernel: usb 1-1: USB disconnect, address 2 Sep 26 05:34:39 (none) kernel: ohci_hcd 0001:01:18.0: wakeup Sep 26 05:34:40 (none) kernel: usb 1-1: new full speed USB device using address 3 Sep 26 05:35:12 (none) kernel: ALSA /home/willy/Pacchi/alsa/alsa- driver-1.0.6a/kbuild/../usb/usx2y/../../alsa-kernel/usb/usx2y/ usbusx2yaudio.c:30 4: Sequence Error!(ep=10;nuc=0,frame=34039) Sep 26 05:35:12 (none) kernel: ohci_hcd 0001:01:18.0: bad entry 50ce000 Sep 26 05:35:19 (none) kernel: ALSA /home/willy/Pacchi/alsa/alsa- driver-1.0.6a/kbuild/../usb/usx2y/../../alsa-kernel/usb/usx2y/ usbusx2yaudio.c:37 0: timeout: still 9 active urbs..

[linux-audio-dev] [ANN] Q multimedia examples released

by Dr.Graef＠t-online.de

Q is a functional programming language based on the term rewriting calculus, see http://q-lang.sourceforge.net for details. This release provides a collection of sample multimedia programs written with Q: - QAudioPlayer, an audio player with waveform and FFT display - QMidiCC, a MidiShare patchbay and transport control - QMidiPlayer, a MidiShare-based MIDI player - QSCSynth, a GUI frontend for SuperCollider These programs also demonstrate how to embed a Q application in a KDE/Qt GUI. A recent KDE version is required (3.2 has been tested). And you'll need the Q core and multimedia packages, of course. Descriptions, screenshots and download links can be found here: http://q-lang.sourceforge.net/examples.html Download, for the impatient: http://sourceforge.net/project/showfiles.php?group_id=96881&package_id=1309… Besides this, there are also new releases of Q-Audio (which now uses PortAudio v19, with support for Alsa and Jack) and Q-Synth (fixes for compatibility with recent SuperCollider versions in CVS). Moreover, FC1 and SuSE 9.1 RPMs for PortAudio v19 and SuperCollider are now also available for your convenience. See http://q-lang.sourceforge.net/download.html Enjoy! -- Dr. Albert Gr"af Dept. of Music-Informatics, University of Mainz, Germany Email: Dr.Graef(a)t-online.de, ag(a)muwiinfa.geschichte.uni-mainz.de WWW: http://www.musikwissenschaft.uni-mainz.de/~ag

[linux-audio-dev] M-Audio Sonica/Ozone/MobilePre/Transit firmware loader now works

by Clemens Ladisch

Hi, it has been reported that the 2.6.8 kernel has fixed the handling of USB resets, so now it's possible to use a Linux firmware loader to get these devices to work. You can get the loader at <http://usb-midi-fw.sf.net/>. Best regards, Clemens

This may sound strange, but I think this is the normal behaviour. Just ignore the message. Is there a problem besides this? (which reminds me, have to release a new version of vstserver soon) --

[linux-audio-dev] Re: This better not be patented...

by Juhana Sadeharju

Hello. I refered earlier to two European papers. Now I found this at their site: Patents on sound rendering. We are in the process of filing for two US patents, together with N. Tsingos and E. Gallo on "Using graphics cards for audio signal processing" and "Perceptual techniques for sound spatialisation" I'm sure the first patent is intended to cover all audio processing in GPUs. This is sad. Even if somebody has given a prior thought on that GPUs could be used for audio processing, it does not help if all these patents cover the only way to transfer and process audio in GPU. The second patent deals with sound source clustering. I have given a thought for that kind of clustering earlier than them when I wrote GVerb. The number of early echoes are reduced by grouping the virtual source points in 3D space and by representing one group with one spatialized source point. They specially mention the early echo reverberator as an application of their method. When a person is killed, it means 8-14 years of prison: a life is cheap compared to the intellectual property, which is worth of 20 years. So, I suggest I keep up with my intellectual property and we implement our version of the invention. Your help is needed in coding.

Re: [linux-audio-dev] Drum synth

by Lachlan Davison

Hey Dmitry, I'm planing to write a drum synth at some point in the very, very near future, for use in the progressive/tribal house and breaks stuff that i try and write. i'm thinking of trying to copy the Electron Machine drum http://www.machinedrum.com/ as much as possible. So implement everything Drumatic does as well as maybe some of the physical modeling stuff suggested on the BeatLAB board. So both roland style synth and physical. Well, i think physical is the best way to get the sound of different tribal drums, which are hard to find with samples. wine 20040309 works fine with Drumatic. though for some strange reason on my machine it seems to run better as a normal user rather than root... RANT TIME (to everyone but dmitry ;). Everytime i talk about a drum synth people point me to a sampler. i think i've worked out what a sampler is for by now or they point me to a modular. Samplers are wonderful but for drums i want both because some flexibility is really nice, i.e being able to change decay and tone just on the fly and tell how it sound with the other elements of the track or slowly change aspects of the drums duing the track, like in Sultan or GPal's tracks. Really i've tried drums in SSM, etc however it's just not quite as useful as a TR808 or drumatic. A) it doesn't sound good B) horrible UI and C) doesn't run too well on my machine (650mhz P3 laptop) Is anybody who writes the great collection of modulars keen on coding a useful synth in one of them? Something along the lines of an Access virus or JP8080 might be handy. Also a bass synth of some discription might be nice too. This is my first ever post to the mailing list because i don't usually like mailing lists much, i can always be found on IRC for more discussion :-) Just thought i should join in on this one, at last talk of a drum synth!! ;-) Loki ---------- Fall in love with everything, fall in love with life, fall in love with music and you will get by.

[linux-audio-dev] A vstserver/wine strange error

by lassantos＠inf.ufrgs.br

Hi all! I am new here and I have a problem in run the vstserver 0.3.1. I did every thing that is in the INSTALL file, but I got some erros: --------- lucasa@Hall9:~/audio/vst-linux$ vstserver VSTSERVER/main: Vstserver 0.3.1 started. Waiting for requests. ----> VSTSERVER/updatecache: Please wait. Updating cache. If nothing happens for 40 seconds, or the server is trying to start the same plugin over and over again; press ctrl-c, and start vstserver once more. VSTSERVER/main: Going to try to start vst plugin "Oberon-4.dll". wine: cannot determine executable type for L"X:\\vstservant.so" --------- I don't know what is this error, because I'm using the vstserver-wine-tar.bz2. Does anyone here know how to fix this? Thanks, I'm a brazilian linux musician.
