Here I am, back again. I've added a song to my site. It's only missing a few things: a real drummer someone who can play bass someone who can sing an entire band that really knows how to play reggae You know, just a few things ;-) This is more a proof of concept than anything else. It's really all about the story (which is on the site). For those interested, the implements of destruction are: Home-made guitar ;-) Roland GR-9 guitar synth (organ) Mesa Boogie Maverick Dual Rectifier 212 Digitech RP250 Blue Ball mic ESP 854 bass through an Art Pro Channel Alesis SR-16 http://www.thecfband.com/Bio/MyMusic/MyMusic.html Oh, the name of the song is "Joe Black" (ya gotta read the story to understand). -- Jan 'Evil Twin' Depner http://myweb.cableone.net/eviltwin69 "Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, chardonnay in one hand, chocolate in the other, body thoroughly used up, totally worn out, and screaming 'WOO HOO, what a ride'"

[LAU] What's some good hardware for recording??

by Brian King

Hello :-) I'm looking for a hardware interface for recording purposes... At the moment I have a basic sound card that I either plug my guitar into and run it into ardour which creates a single track or I have a mic that sits in the middle of everyone jamming but I'd like to get a m-audio delta 44 or similar so I can have more than one input stream for multi track recording?? I've heard of a delta 1010LT which has 2 preamped microphone inputs which is good..... So what else is out there that's in this vein??? Other brands that are just as compatible in linux?? I like the breakout box type connection interface....

[LAU] What hardware is actually used by freebob/ffado users?

by Pieter Palmers

[Appologies for the cross-posting] [Please DON'T use reply-to-all to reply on this email] Hi all, With this I'm hoping to gather some data that can help us in convincing the firewire device manufacturers that we are of some significance to their sales (I'm actually wondering if we are...). So I would like to ask everyone on these lists that has/considers/considered purchasing a firewire audio device if they would be so kind as to answer the following questionnaire. ** Those that have bought one or more firewire devices... * can you provide which device(s), preferably with their GUID (can be found out using gscanbus or sometimes on the device itself) * Do they work with linux? ** Those that considered buying a firewire device: * What device(s) did you consider buying? * What device did you go for in the end (if applicable)? * To what extent was the lack of Linux support a determining factor in your decision? ** Those that consider buying a firewire device: * What device(s) are you consider buying? * How important is Linux support for you? ** any comments? It would be nice if you would reply to this email with the answers inlined with the questions. Please don't reply-to-all but reply to pieterp(a)joow.be in order not to spam the mailing list with these answers. It would also be nice if you left the subject line intact such that I can auto-filter these messages. Again, sorry to bother you guys with this, but it's a bit difficult to convince manufacturers without some decent data. Thanks, Pieter Palmers ffado.org PS: If you know other freebob/ffado users that are not subscribed to these list please pass this mail on.

[LAU] Ati driver installation for low latency kernel (Kubuntu)

by Matthias Schönborn

Hi list! This is my first post and I hope it's not too off-topic.. I've already posted it in the Kubuntu forums but got no reply, so I hope that someone here can help me. My problem is as follows: On my notebook I have installed Kubuntu, and for my everyday work I use a generic kernel, because the low latency kernel would drain too much power, so that the battery would be empty very soon. For recording I use a low latency kernel. Now the problem is, that in the Ati driver installation, the kernel is modified. If I install the driver while using the generic kernel, it works well with the generic kernel. If I then boot the low latency kernel and install the driver, it only works with the low latency kernel, but not anymore with the generic kernel. Now I would be fine without 3D acceleration while I'm using the low latency kernel, but the annoying thing is that sometimes the system freezes if the driver doesn't work properly. Can anyone help me solve the issue, or does someone know a workaround? I would be most gratefull! Thanks, Matthias

But it seems like your agenda is to defend Ardour, no matter what. In case that is true, why? Oh, and you are completely wrong, by the way. Traverso's interface is not about simplicity and intuitivity, you had known that if you had tried traverso. (and especially protux, its predecessor). And yes, I must admit I have a small agenda too, against Ardour. I don't think ardour's user interface is very efficient [1]. Ardour is great, but it would have been even greater if all the developers on ardour spent all of their time exclusively working on making ardour's user interface more efficient to use. Traverso is an excellent program to look at to improve the situation. [1] http://lists.ardour.org/pipermail/ardour-dev-ardour.org/2007-March/004085.h…

[LAU] Time to update system - thoughts on SUSE 10.2 + JackLab?

by David Haggett

Hi, List Have run into too many dependency issues on my existing SUSE 9.3 x86_64 system, and am now considering a migration to a more recent platform. My main aim is not to have to relearn too much linux stuff, and get up-and-running as quickly as possible (my PC is also my practice amp). I've read the installation guide on the JackLab wiki: <http://wiki.jacklab.net/index.php/3_Steps_to_JAD_for_Beginners> I noticed that it recommends to use the 32bit variant, but cites VSTs as the only reason. Are there other reasons not to use the 64bit version (I have an Athlon64 and no desire to use VST plugins)? I currently have no difficulties running the NVidia 3D driver on a realtime enabled kernel. Are there any known and unresolved problems with the JAD kernel and NVidia? TIA -- David Haggett

Re: [LAU] Realtek ALC882D

by Daniel Garmendia

I have made two graphs of the hums frequency content (via some Matlab wizardry). The "zoomedout.jpg" shows most of the frequencies in the signal. The "zoomedin.jpg" shows that 60 Hz is by far the loudest frequency. Interpret as you please. http://www.prism.gatech.edu/~gtg601q/LAU/zoomedout.jpg http://www.prism.gatech.edu/~gtg601q/LAU/zoomedin.jpg -DanielG On 7/30/07, linux-audio-user-request(a)lists.linuxaudio.org < linux-audio-user-request(a)lists.linuxaudio.org> wrote: > > > ------------------------------ > > > I have been told that this is probably caused by the power distribution > circuitry within the laptop: it does not separate earth ground from "signal" > (I'm assuming USB signal since my audio interface is USB) ground.

[LAU] Realtek ALC882D

by Chris McCormick

Hi All, I'm about to purchase this ASUS laptop: <http://www.alvio.com/config.aspx?t=&product_ID=11110> I was just wondering if anyone had experience with the sound device (Realtek ALC882D) or this laptop specifically? I will be 'touring' with it next year. I chose this ASUS over a macbook based on the testimonies on this list earlier in the year; thanks for yr help! Best, Chris. ------------------- http://mccormick.cx
