[linux-audio-user] what's the best option here? / SosPubs article

by Kent, Gary

Hi: Last nite I read that article in SosPubs about Linux. Most folks in that article seemed to be using the RME HDSP 9652. I have been looking at the MultiFace for awhile, but am starting to feel that the best option would be to sink my money into some of the preamp/ADAT optical out outboard gear that is starting to come on the scene such as the M-Audio Octane, Tango24, or Behringher ADA8000 that feature lots of preamps w/ ADAT optical outputs, and just using the HDSP9652 as a really nice signal router into my Linux box. Would anyone be willing to share with me the pros and cons of this approach? Up until now I have been thinking about sinking all of my money into the MultiFace or a really high-priced audio card with minimal outboard. Now I'm starting to think just the opposite that just using a bare minimum optical card w/ decent converters and putting my money into outboard would maybe be the best way. Any good advice on this, and if so, any other cards I should consider? Thanks very much, gk

[linux-audio-user] Stuttering via HDSP, Cardbus, Multiface? More Info

by Timothy Polashek

It is great to see others have experienced this problem, and are trying to find a solution! The jitter/granular distortion that Tim (the other Tim!), Ico, and Derek describe seems to match exactly what I am experiencing, however I think my hardware is completely different. I wanted to post information about my current state for the record before I start experimenting with acpi and all the other suggestions. I am only on the CCRMA and LAU list, so feel free to forward this info to other lists, such as alsa or whatever.

[linux-audio-user] Beginner sampler questions

by Chris Metzler

Hi. I've been playing guitar for 7 years or so, and using linux in one way or another for about the same amount of time; but only this past year have I started playing around with what I can do musically with my linux box. One of the things I've recently learned about is samplers. As I understand it at this point (and I'm hoping someone will set me straight if I'm wrong), a sampler accomplishes basically the same thing as a wavetable synth -- it uses sound samples to generate tones, doing frequency shifting and interpolation as necessary. And as I understand it, the main difference between a sampler and a wavetable synth is the lack of constraints on the samples used -- with a sampler, anything at all could be a perfectly good sample, including samples of almost arbitrary duration (and thus size). One of the most obvious uses I can see for a sampler would be to use it to provide instrumentation that the user doesn't know how to play. For instance, if I wanted to record myself on guitar with a piano accompaniment, I could use a sequencer to write the piano line and generate it through a sampler. But that brings my first question -- if you don't own/play the instruments in question, where do you get the samples? I've done a lot of web searching, and found tons of drum loops and bass lines that are two measures long and so forth, but don't find much in the way of e.g. individual notes on basses. And I wonder about how people use the extended samples I find. It seems kinda constraining, to be stuck with a melody/harmony line given to you by whatever someone sampled. Of course, there are tons and tons of samples available; but then, in order to express the music you're hearing in your head, you're gonna be spending hours and hours trying to find samples that work. Am I missing some obvious things here? How do people use samplers, for the most part? Thanks for dealing with my beginner-type questions. -c -- Chris Metzler cmetzler(a)speakeasy.snip-me.net (remove "snip-me." to email) "As a child I understood how to give; I have forgotten this grace since I have become civilized." - Chief Luther Standing Bear

by sigir

I'm looking for an OmniStudio USB (see other message). But it doesn't have S/PDIF. I think I can add the ESI WaveTerminal U24 : http://www.esi-pro.com/viewProduct.php?pid=10&page=1 I see 3 WaveTerminal on http://www.alsa-project.org/alsa-doc/index.php3?vendor=vendor-Ego_Sys#matrix Do you know if it works with Linux?

[linux-audio-user] OmniStudio USB

by sigir

On http://www.alsa-project.org/alsa-doc/index.php3?vendor=vendor-MAudio#matrix there is the USB Audio Quattro, but the USB Audio Omni Studio is "untested". On M-Audio site, they said that it's the same as Quattro with some features more. Do you know if OmniStudio USB works with Linux? (Debian) Thank you -- sigir

[linux-audio-user] Suse vs. VXPocket on a T40 Thinkpad

by Geoffrey Martin

Hi, I'm installing Suse 9.0 on an IBM T40 Thinkpad with a Digigram VXPocket soundcard (for the third attempt...). Suse cannot detect that the sound card is there (it sees the internal card). When I try to override this and install manually, I get the following message An error occured during the installation of VXPocket, Digigram The kernel module snd-vxpocket for sound support could not be loaded. This can be caused by incorrect module parameters, including invalid IO or IRQ parameters. Anyone out there have any thoughts on how to fix this problem? I've exhausted everything I know of.... Thanks -geoff ____________________________________________________ Geoff Martin Ph.D. Tonmeister, Bang & Olufsen a/s email: ggm(a)bang-olufsen.dk web: www.bang-olufsen.com web: www.tonmeister.ca phone: +45 96 84 49 54

Re: [linux-audio-user] Re: Recent LKML discussion on preempt/latency in 2.6 kernels

But with DRI off, Qjackctl and some real Jack applications I do > get xruns even at 128x2, I guess my cpu is maxing out... I'm confused. I probably have misunderstood something, but: First you say, that you get a "hanging machine" with SCEHD_FIFO enabled applications, but later you say that you can run Jack with SCHED_FIFO with all the different configurations/kernels you mention. What do you mean with a hanging machine? Do you get 'random' lockups, or does your system hang always when some specific software is run with SCHED_FIFO? Do you get lockups with this kernel & setup (option d in your email)? Could you give a list of specific patches (and urls) you have applied to 2.6.4-1.286.2.ll (option d), or maybe a link to the source package? Sampo

[linux-audio-user] couple of muse questions

by antoine rivoire

Hi all. a simple stupid question: in muse the tempo is in percentage? or is 100 really 100 bpm? what is the rationale here? Secondly when starting muse as a normal user I get: cannot open rtc clock /dev/rtc: Permission denied how can I change the permission permanently? kernel 2.6 with realtime.0.04 Regards -- antoine rivoire <antoine.rivoire(a)ntlworld.com>
