I am going to be setting up a second machine (probably Windows) to use as a dedicated machine for VST plugins and instruments, and I plan to use SP/DIF between my Linux DAW and the Windows box for the send/return (getting a Delta1010 for Linux and moving my M-Audio 2496 to the Windows boix). Is latency going to be an issue with this kind of setup and if so, how would I compensate in Ardour or other applications? -- Brett ----------- Programmer by day, Guitarist by Night http://www.chapelperilous.net http://www.alhazred.com http://www.revelmoon.com

[linux-audio-user] Latest real-time benchmarking results

by Maluvia

Just finished reading Con Kolivas' latest benchmarks on the 2.6.12 kernel over at kerneltrap (http://kerneltrap.org/node/5466) - and found them quite interesting. I was wondering if there is anyone using Ingo Molnar's latest RT-preempt patch who has been unable to obtain acceptable latencies without it?

Re: [linux-audio-user] 2.6.12-3 multimedia kernel--snd-mpu401 does not modprobe

What soundcard are you using? I have > experienced problems with the i8x0 alsa drivers (since alsa-1.0.6). It is attempting to load the driver as per the preexisting successful alsa configuration and this fails. I had to place the sequencer in /etc/modules at one point when this was being skipped but load of snd-mpu401 fails. I am using it to drive and older sw60xg sound generator. This card uses no IRQ or DMA, just a port address. So the driver is being modprobed with appropriate port=0x300 irq=-1 options. Maybe this stuff has changed?

[linux-audio-user] 2.6.12-3 multimedia kernel--snd-mpu401 does not modprobe

by David Baron

Anyone had this? Fixed it? The module file is in place. (This kernel was on Debian Sid. Kernel headers available, not sources. Realtime-lsm--needed or not needed--will compile with the headers as will the directory rendering modules.)

[linux-audio-user] homemade music -- notation

by Steve D

Recently I posted a link to a rough-draft recording I made of a piece I composed some days ago, "Abstraction 1 for Piano"-- OGG version: http://www.xscd.com/pub/music/audio/ogg/abstraction-1-for-piano.ogg MP3 version: http://www.xscd.com/pub/music/audio/mp3/abstraction-1-for-piano.mp3 I decided to use the piece as an excuse to dig into the music notation program LilyPond again and try to improve my rudimentary skills: http://www.lilypond.org/ If anyone cares to see the score, or hear the rather mechanical sounding MIDI file produced by LilyPond from the source code of the score, they are here: PDF score: http://www.xscd.com/pub/music/scores__notation/pdf/abstraction-1-for-piano.… MIDI file: http://www.xscd.com/pub/music/midi/abstraction-1-for-piano.mid I love LilyPond. It takes a bit of learning and getting used to, but it is really a great program.

[linux-audio-user] hi list...

by Wolfgang Lonien

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi LA users, after approx. a 20-year-break as a musician, I decided to get some MIDI equipment and do something more fun with all these computers. And wow it seems hard. I still remember someday when I bought my first MIDI stuff and started with DOS - so this was pre-Cubase & Co, and everything worked fine with some soundblaster and the Y-cable. Now I am reading since days about low-latency, tried both the live and the install of DeMuDi, configured an older companies' laptop (Asus with P3-750) to make use of my MidiSport2x2, and since then I'm fuddling around with jackd, alsa, rosegarden4, muse, and all the like. The latencies are horrible. Ok; it's UNIX/Linux, and that is meant for more than one person, I know, but I didn't assume it to be *that* hard. So I'm greeting all members of this list, and since I'm obviously a (rather old, I know) "newbie", don't kill me because of the questions I might ask here. Oh, andd thanks to all the authors of these great & free applications - as well as all the others who are writing good articles about them. Life is fun again ;-) cheers, wjl aka Wolfgang Lonien from Bremen, Germany - -- Key ID 0x728d9bd0 - public key available at wwwkeys.de.pgp.net Honda NTV '94 still running on fuel - everything else here runs Debian GNU/Linux -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) Comment: Using GnuPG with Thunderbird - http://enigmail.mozdev.org iD8DBQFC35RbqrjTanKNm9ARAm8OAKCDiuAuraQvu8rf+/AVD3rweM4CSwCfe4lJ EkIW0jJr6GSjFdjPYDEXSqM= =GV7R -----END PGP SIGNATURE-----

[linux-audio-user] jack and Edirol UA-1A USB soundcard

by Atte André Jensen

Hi I'm trying to get jack running with my Edirol UA-1A USB soundcard. The card works well with alsa (so no jack) but my system freezes after a while (often when a client, fx xmms or ams) disconnects. Anybody has a clue how to proceed or what could be wrong? Here's some hopefully relevant info: atte@aarhus:~$ cat .jackdrc /usr/bin/jackd -R -dalsa -dhw:1 -r44100 -p256 -n3 atte@aarhus:~$ cat /proc/asound/cards 0 [SI7012 ]: ICH - SiS SI7012 SiS SI7012 with ALC200,200P at 0xdc00, irq 10 1 [UA1A ]: USB-Audio - EDIROL UA-1A Roland EDIROL UA-1A at usb-0000:00:03.1-2, full speed atte@aarhus:~$ cat /etc/modutils/alsa alias char-major-116 snd alias char-major-14 soundcore # i810 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss alias snd-card-0 snd-intel8x0 alias sound-slot-0 snd-card-0 # ua-1a alias sound-service-1-0 snd-mixer-oss alias sound-service-1-3 snd-pcm-oss alias sound-service-1-8 snd-seq-oss alias sound-service-1-12 snd-pcm-oss alias snd-card-1 snd-usb-audio alias sound-slot-1 snd-card-1 # virtual midi alias sound-service-2-1 snd-seq-oss alias sound-service-2-8 snd-seq-oss alias snd-card-2 snd-virmidi alias sound-slot-2 snd-card-2 #evolution 1 alias snd-card-3 snd-usb-audio alias sound-slot-3 snd-card-3 #evolution 2 alias snd-card-4 snd-usb-audio alias sound-slot-4 snd-card-4 # options snd-intel8x0 index=0 options snd-usb-audio index=1,3,4 vid=0x0582 -- .''`.
