Hello, My name is Kevin Kelley and I have been working with Unix/Linux for quite some time at work (mainly VoIP and slackware). I joined this list hoping to get some idea of what linux distribution to use for my home studio. I mainly need midi for sequencing and I may do some audio recording and effects and if all goes well I may try some soft synths. I currently have a large collection of vintage synths that I plan to mainly use. The question is for a new Linux audio user what is the easiest Linux distribution to setup and use and what programs work best. Sorry I am sure everyone has their own opinions but in this situation that is what I am looking for. I mainly build every thing from source on slacking as well as rebuild the base kernel per machine for work. Kevin Kelley www.keyboardmuseum.org

[LAU] A Linux Audio distro that can keep up?

by Darren Landrum

Is it really too much to ask for a distro which is supposedly dedicated to audio and video production work to keep up with the latest versions of those types of programs and libraries? Ubuntu Studio 64 v8.04 (Hardy) is still stuck at Ardour 2.3. I can't even get the Rubber Band library to compile because I can't get vamp-sdk to compile either, so now I can't compile Rui's Qtractor with the options I want. You'd think they'd all be in the Ubuntu Studio repositories, but they're nowhere to be found. Is there a distro for audio out there with a nice real-time kernel that can keep up with the updates so I don't have to keep doing it all manually? Thanks! -- Darren Landrum

[LAU] M-Audio MIDISport UNO Compatable with Linux?

by mowestusa

Hello, I'm trying to set up a simple Midi interface between a Linux box and a Midi keyboard. Will the M-Audio MIDIsport UNO work with Linux? I bought it on sale for $19.99, and I'm hoping it will work with Rosegarden and other Midi programs under Linux. Thanks, ---------------------------- | Steve | | mowestusa(a)yahoo.com | | mowestusa.nixsyspaus.org | ----------------------------

[LAU] Lexicon Omega

by Joshua Boyd

My Omega seems to have developed flacky output jacks, and maybe also flacky input jacks. Has anyone seen this on theirs, since I seem to recall a few people on here using them? I'm torn between sending it to be repaired, trying to repair it myself, versus just replacing it with a simpler device and dragging my mixing board back out. I'm concerned that trying to send it out for repair would end up costing more than I paid for it or even almost as much as a brand new one would be. Has anyone who owns one tried opening it up?

[LAU] Intercept (alsa) audio from totem-xinelib

by Johannes

Hi all, I would like to watch a video DVD with totem and send the audio to a file instead of the sound system (that is, capture the DVD audio as it flows). Could someone point me to the right direction? I tried adding a .asoundrc file to my homedir, containing pcm.fileout { type file slave.pcm "hw:0,0" file alsaout.raw } but can't figure out how to actually activate "fileout". My installation is ubuntustudio (gutsy, i686) with totem-xinelib. I picked ALSA for "Music and Movies > SOund playback" in System > Preferences > Audio (=gnome-sound-properties) The soundcard selected in QAMix is "VIA8237 (hw:0)" Thanks all in advance, Johannes

[LAU] MIDI latency in Ubuntu 8.04

by David Baird

When I use the kernels from Ubuntu 8.04, my MIDI latency becomes horrible. I have an external keyboard that connects to the computer and then proceeds to loop-back out to external synthesizers. By horrible, I mean that there is quite clearly a delay from when I hit a key on my keyboard to when sound comes out the synthesizer. If someone knows a tool I could use to measure the latency, I'd be glad too. Otherwise, I'd just guess it is somewhere around 100 milliseconds. When I switch back to my prior kernel from Ubuntu 7.10, the latency becomes great (but the X server and other things stop working, thanks to the magic of Ubuntu). Here are the kernels I've tried out with Ubuntu 8.10: 2.6.24-18-generic Bad latency 2.6.24-18-rt Bad latency 2.6.22-14-generic (This is the kernel from Ubuntu 7.10) Excellent latency Has anyone else had this problem? Do you know if it is kernel-related, library-related, or Ubuntu-related? It almost seems kernel-related, but why? -David

[LAU] Playing lilypond midi drum files with synth/sampler

by Grammostola Rosea

Hi, I want to write drum score in lilypond, export it to midi and play that with a sequencer. Which programs are the best for this? Muse, Rosegarden, Qtractor? Linuxsampler (gigedit) or specimen? How does the mapping work? The sequencers do use standard midi percussion maps...(?) Here is one: http://www.midistudio.com/Help/GMSpecs_PercMap.htm Key 35 is that key 35 on a 88 keys piano from left to right? so key 35 is G3? Thanks in advance,

[LAU] pulse audio with two cards Re: [LAD] joining the fun...

I'm sure others on this list may be able to offer some more insight. I'm assuming that you are using alsa drivers and that you can see the second card in /proc/asound/card1 What is the interface for PA saying when you try to access the second card? It's probably a asoundrc issue but it may be a bug with PA that you have found. Cheers. -- Patrick Shirkey Boost Hardware Ltd.
