[linux-audio-user] sites at linuxaudio.org

by Pieter Palmers

I was just now looking for some links with respect to low latency configuration to put on the freebob site. I knew that there are some sites *.linuxaudio.org, but I had to use my memory & a gamble to find them (lau.linuxaudio.org, lad.linuxaudio.org). Wouldn't it be good if the main linuxaudio.org site had a link to all the sub-sites available? Greets, Pieter

[linux-audio-user] Ubuntu Studio: an interview with project manager Cory Kontros

by Jon H

Hey all, Recently there was a lot of rumblings on the news portals about Ubuntu Studio. It's a project that until recently had been active pretty much as just an audio-on-ubuntu wiki but the news suggested it was growing into something quite a bit more. Deciding to take a look for myself I ended up in the project's IRC channel and borrowed some of the valuable time of Cory Kontros, the project's manager, for a quick interview. Take a look if you like: http://oktyabr.wordpress.com/2007/01/27/ubuntu-studio-an-interview-with-pro… Best, Jon Hoskins

[linux-audio-user] debian / ubuntu

by greg

Ok, hopefully this will not set off a flame war :) Basically my experience with ubuntu has been that when it works right and you stay in the lines, it's great. Fixing problems or doing something unorthodox occasionally involves a touch of smoke and mirrors. Just for fun I thought I would give regular Debian a try. I just installed Debian on another machine. It's in the process of upgrading to "testing". I thought the documentation for Debian was very straight-forward, but perhaps scary to the text-file phobic, but that's where I always ended up in Ubuntu. Questions: - is that an accurate debian / ubuntu difference, what else is there? Basically the only sense i've gotten is that ubuntu is friendly, debian is balanced(?) and gentoo is for freaks. I kid. - is testing a good choice? From the description I am expecting current, but not bleeding edge packages and a machine that is unlikely to blow up. - will it be "easier" to do a machine based on compile-installs etc and not just relying on apt-get with debian than ubuntu. So therefore might it be easier to transition to a realtime machine. For my purposes edgy's 18ish kernel hasn't failed me yet, but hey. wow that turned out to be long but it's some stuff I'd been curious about.

[linux-audio-user] linux sampler and rosegarden

by BJaY

Hi, I was just reviewing some projects (again) and noticed that during the loading of the projects, the stating of rosegarden set the volumes of some (but not all) of the linuxsampler channels to 48. I've done nothing that I'm aware of to make it do this, all channels should be at full volume. When I change the volume control for the midi channel in rosegarden, the volume of the channel changes in qsampler but not to its full extent. I'm using planet CCRMA on FC6 (32 bit)- a recent version of linuxsampler and qsampler that Nando did to fix the 'immediate crash' bug. On an aside - the most immediately usfull tools for general musicians are the software synths - qsynth and qsampler - and I've had loads of trouble with them. With ZynAddSubFX having problems with real time (and soft synths are only any use with real time), users of linux audio are left with very few options. What can we do ? Cheers, Bruce.

[linux-audio-user] Monitoring (processed) input during playpack in Ardour

by Cesare Marilungo

Is there a way, in Ardour (I've just compiled 2beta10), to listen (monitor the input of) a track while playing back the other tracks with software monitoring (and thus having the input sound processed in realtime through some ladspa effects)? I can hear the input while recording (obviously), but sometimes I want to play over the tracks I've already recorded without recording a new track. This is how other DAWs I've used behave. Any hint? Thanks, c. -- http://www.cesaremarilungo.com

[linux-audio-user] midi timings

by we are

hey crew. just a quick question, i have had a lot of pain figuring out this midi timing issue but got it thanks to this page http://tapas.affenbande.org/wordpress/?page_id=40 when i cat /proc/sys/dev/rtc/max-user-freq it returns 64 which is always useless for midi audio work. so as suggested i simply echo 8192 > /proc/sys/dev/rtc/max-user-freq which brings it back up 8192. so, how do i make this a permanent thing so i don't have to type it in at every startup. also, is this the best/standard way to fix my midi timing issue, it works but is there any diadvantage to it. i only wonder this because it defualts to 64. thanks laters ps using up to date gentoo system with the pro-audio overlay

Re: [linux-audio-user] Where's the weak link?

by linuxmedia4＠netscape.net

I either found the culprit of the xruns, or I found the *main* one. But I have a question... I noticed that the xruns were every 20 seconds. So I went to KDE Control Center -> Power Control -> Laptop Battery... and changed "Check status every: 20sec" to "Check status every: 1sec". I started Qjackctl... and as suspected... there was one xrun per second. I couldn't shut off "Battery Polling" in KDE Control Center, so I set it to a ridiculously high number and the "regular" xruns stopped. I wanted to completely shut off "Battery Polling", and I was under the impression that this was controlled by "apm". So I set it back to "1 second polling" and went to System -> Services and disabled "apmd". That didn't effect the nibbling at the hard drive every second, but it stopped creating an xrun every second. Although there still were "regular" xruns. Does anyone have any idea how to disable "Battery Polling"? Thanks, Rocco

[linux-audio-user] another very cheap usb card ...

by Georg Holzmann

Hallo! I just found this very small and cheap card (something like 12€): http://www.speedlink.de/prod.php?lang=en&sys_id=8&pb_id=12&prod_num=SL-8850 http://www.speedlink.de/support.php?lang=en&view=1&sys_id=8&pb_id=12&prod_n… Because I was looking for something like this I wanted to ask, if this card should be supported by the general USB driver ? (It says that on windows it will work out of the box with no special driver - so I guess it should also work on linux ?) Thanks, LG Georg

[linux-audio-user] notation program needed

by Josh Lawrence

Hello all, I need the ability to generate very small pieces of musical notation for instructional purposes. For example, I need to show the student a particular chord or voicing; I would like for this program to be gui-controlled so I can open up a 1 bar grand staff, stack whole notes, and export that to some image format to be included in text or on the web. I've worked with Lilypond, and while it is amazing and very powerful, it is too powerful and complex for my needs. At one time there was a simple gui front-end to Lilypond, but I think it is no longer maintained. Does anyone have any suggestions? Thank you, -- Josh Lawrence http://www.hardbop200.com
