[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) --

Hi, i just scratched an itch i had for some time. A command line based small and simple utility to store/restore jack connection states. Thus i release this initial [hack] version. Maybe someone else finds it useful. http://www.affenbande.org/~tapas/wiki/index.php?jack_snapshot flo

[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.

[linux-audio-dev] ANNOUNCE: Polypaudio 0.5.1

by Lennart Poettering

Hi! A few minutes ago I released version 0.5.1 of the Polypaudio sound server. Changes include: - improved esound protocol compatibility - fix autospawning via libesd - make use of POSIX capabilities - allow SCHED_FIFO scheduling only for users in group realtime - minor build system fix. Since I didn't announce Polypaudio 0.5 on the LAD list, here is the changelog of 0.5: - extensive API improvements - new module module-combine for combining multiple sound cards into one - gcc 2.95 compatibility - configuration files - "lazy" samples - support for source and network latency measurements (in addition to sink latency measurements) - add module-pipe-source - many other fixes and improvements. Thanks, Lennart -- name { Lennart Poettering } loc { Hamburg - Germany } mail { mzft (at) 0pointer (dot) de } gpg { 1A015CC4 } www { http://0pointer.de/lennart/ } icq# { 11060553 }

[linux-audio-dev] P4 kernel patch/option against denormals

by derek holzer

Hi all, I have had non-stop CPU spikes and freezes related to denormal numbers on my Pentium 4 1.6GHz laptop ever since I switch to Linux, going from kernel 2.4.18 up to 2.6.4. The main applications which seem to be affected are Freqtweak, Jamin and Pure Data, along with a handful of LADSPA plugins, which can sometimes make my Ardour sessions a real PITA. Does everyone develop on Celerons or AMDs these days?!? ;-) I have pursued the problem in particular with Pure Data, but have been assured that there is already denormal handling in the program... It has gotten to the point where either I find a kernel-level solution for the problem or I buy a new laptop! Tim Blechman reported on the PD list that his denormal problems only started when he switched from SuSE to Gentoo. My suspicion is that the SuSE kernel developers either cooked up a very good patch against denormals, or they are using a proprietary Intel compiler for their kernels which somehow alleviates the problem. For my own purposes, the former is more attractive than the latter, of course. Tim also mentioned that some P4s have a Denormals-As-Zero switch to handle the problem [although I suspect that my CPU might be too old for this feature...]. Can anyone explain how such a DAZ switch can be tested for and toggled? Can anybody shed some light on the situation? I would hate to have to ditch a decent computer over this issue. best wishes, Derek -- derek holzer ::: http://www.umatic.nl ---Oblique Strategy # 127: "Openly resist change"
