[LAU] OT What newer CDR/RW drives should I consider?

by Vince Werber

Hi Folks... It's about time for me to get a few more CD-R/RW drives for a Slackware 11 box... Only CD read and write are required, speed isn't an issue either... Price is but these things seems to be low enough in price these days so even that doesn't seem to be an issue... Writing is the important part... I don't rip CD's anyway... So... what new units do you all recommend these days??? Thanks in advanced vince aka Wesa http://vincewerber.org

[LAU] simple DJ program

by M-.-n

Hi, Still exploring the Eee possibilities, is there a simple mp3 mixing program out there ? No even doing real time stretching but lightweight with two playlist and an assignable USB crossfader would be nice. Is there such a thing ? Thanks Marc

[LAU] [OT] cc music licensing for a film [update]

by Cesare Marilungo

Thank you all once again for your help. I've just received a mail from the producer. They asked me to fax them a letter granting them non-exclusive SYNC, MASTER USE, PERFORMANCE and VIDEOGRAM licenses for three tracks (they added another one: "Hope"). I can't afford a lawyer (and I don't think it would be worth anyway). So I'm doing everything myself (writing the letter etc.) If you're curious here's some info about the movie at imdb: http://www.imdb.com/title/tt1130968/ They offered me a donation (don't know the amount, and no royalties), plus possibly a second donation based on the success and the distribution of the film. This is the first movie for both the producer and the director. They seem nice, and so I accepted. Cheers, -c. -- www.cesaremarilungo.com

[LAU] a SndObj Library tutorial?

by Francisco López

Hi list, I was wondering if any of you know about a good SndObj Sound Object Library Page tutorial for dummy like me. The only documentation i can find on the home page (http://sndobj.sourceforge.net/) is the complete reference manual and some uncommented source code of simple applications. But since i'm just starting to code on c++, i'll need something more "step by step" or "dumb proof"... Any tips? Thanks, -Fran

[LAU] Eee As Synth Engine?

by holotone＠gmail.com

I've been tinkering recently with my Eee running Xubuntu and a newly acquired M-Audio Axiom 49 USB Midi Keyboard; I think it'd be just about as great as it could get if I could use the Eee as a synth engine via XynAddSubFX or similar - Unfortunately, I've been unable to tweak my JACK settings to the point that all stutters and chops have been eliminated. I understand that the Eee specs are quite low (900mhz proc, 512MB RAM), but watching my resource usage while I'm playing shows the processor at less than 50% and RAM holding steady at 60% or so - This would lead me to believe that my problem is configuration related. Any other Eee users out there had any luck getting JACK fine tuned to the Eee? Since we're all working on nearly identical hardware, perhaps we could swap configs? Thanks! -- ~holotone http://holotone.net/

[LAU] [Fwd: Re: Freebob problem with M-Audio Firewire Solo breakout box]

by verymeta＠riseup.net

THANK YOU!!! It works! I feel stupid - really the only reason I wasn't getting sound was I had the wrong input selected on my Firewire Solo box.. I was sure FreeBob wasn't working, because aplay -l didn't work, and it hadn't occurred to me to try starting Ardour, but as soon as I did I saw that it was showing the inputs and outputs from my Firewire Solo. I can't tell you how great it feels to get audio, after a week of struggling with this!!

[LAU] Freebob problem with M-Audio Firewire Solo breakout box

by verymeta＠riseup.net

Hi, I apologize for cross-posting, as I've already sent this to the Ubuntu Studio list, but I don't think the problem is specific to Ubuntu... I need some help getting Freebob to work with my new M-Audio Firewire Solo device instead of a soundcard. When I run gscanbus, the Firewire Solo is recognised, but when I do $ aplay -l I get the message: aplay: device_list:204: no soundcards found... However I know that the Jack server can 'see' the Firewire Solo in some way because if I do $ jackd -d freebob without the Solo plugged in, Jack won't start. But if the Solo is plugged in Jack will start, and I get the messages: JACK compiled with System V SHM support. loading driver .. SSE2 detected Freebob using Firewire port 0, node -1 libiec61883 warning: Established connection on channel 0. You may need to manually set the channel on the receiving node. libiec61883 warning: Established connection on channel 1. You may need to manually set the channel on the receiving node. But still I don't get any sound. I have no idea what 'manually set the channel on the receiving node' means. Also, I don't know if this is meaningful in any way, but when I open qjackctl and go to setup, the 'input device', 'output device', 'input channels', and 'output channels' drop-down boxes are greyed out. I've read all the info I could find on this from Google searches (though a lot of it is way over my head) and I'm running out of things to try to make this work, does anyone have any ideas? Thanks, -Katie.

[LAU] jack and RT-patched kernels

by Julien Claassen

Hi everyone! I narrowed my recent problem down to not being LinuxSampler, but either jack or its interaction with the kernel. So: Does any of you use 2.6.23.1-rt11 or 2.6.24-rt1 in conjunction with jack? How well does it work? Is it easy to make connections when the system is working nicely (with a good deal of memory in use)? I still have trouble connecting my linuxsampler when I've loaded my 1.3gig sample (32768 samples in RAM) or when I use fluidsynth with a very big soundfont (200M). It's all much too instable? Suggestions anyone? What to test? Where to start? Kindest regards Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net the Linux TextBased Studio guide ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de

[LAU] OT: book - Musimathics

by Greg

Dr. Gareth Loy, Musimathics 1 and 2 Has anybody read these books? I did a quick search of my archive of the list and it doesn't look like they've been discussed here. Vol I is "musical elements," Vol II is "musical signals." Judging by the table of contents they appear to be comprehensive. www.musimathics.com
