[linux-audio-user] Re: Korg Keyboard running Linux

by Juhana Sadeharju

Have you ever wondered why the new OASYS, Nord Modular G2, etc. have digital rotary knobs with the LED lights on the base of the knob? The knobs have a problem: when one does not look at the knobs from top, the LEDs are hidden by the knob itself and thus the value may go unseen. It appears that Euphonix (http://www.euphonix.com) has a patent on the knob where the LEDs are on the top of the knob (instead of base). LEDs are always visible. Why I wanted to tell all this is that prior the patent, when we had an electronics club at our elementary school, we came up with this patented knob design -- and we thought and laughed that it already must have been patented multiple times. Wrong. I have made an alternative design by now. Juhana -- http://music.columbia.edu/mailman/listinfo/linux-graphics-dev for developers of open source graphics software

Possible, but not without a struggle. Does anyone know how to get nvidia drivers loaded for the 2.6.9-multimedia-686 kernel? I've tried 3 or 4 methods and haven't gotten it. Says something about VMALLOC error. I've made significant progress though. At this rate maybe I can restart all over again with just DeMuDi and get the video working from the start... Jon

[linux-audio-user] AacPlus compared to Ogg

by Steven Clift

I understand the licensing differences between Ogg and MP3. What about the newer aacPlus? The new KCMP is using aacPlus because they claim they can webcast near CD-quality with a pretty small stream: http://minnesota.publicradio.org/radio/services/thecurrent/ (It is great! I am trying to get them to add Ogg and MP3 to reach more people.

[linux-audio-user] [OT] Have you ever felt this way about your gear?

by Curtis Sloan

Sorry for the OT post, but I thought maybe the LAU crowd would appreciate the following story. True or not, it's good for laugh. ------ (Comment copied from http://slashdot.org/comments.pl?sid=136725&threshold=1&commentsort=0&mode=t…) Re:A Piano... (Score:5, Funny) by mr i want to go home (610257) on Thursday January 20, @04:06PM (#11424155) I had a lot of friends who were making electronic music back in the mid 90's. This was when an old classic analogue synth from the 70's could be sold for thousands of dollars. Anyway, this guy I kind of knew had a problem with one of his old synths. In the middle of the night, he would be recording something and it would suddenly start squealing away. You'd walk up to it and it would stop. Turn your back on it and it would start again...all sorts of weird stuff like that. He was taking loads of e's and acid at the time which maybe why he decided that it had become possessed by Satan. He started loosing a lot of sleep over it - mostly because it would turn itself on during the night and bleep away. One night he couldn't take it any more, and took to it with a sledge hammer. He collected the pieces and burned them with diesel. We thought that was a bit tragic (it was a great synth), but he was adamant that the Evil must be destroyed. After that he disappeared for a while. I wasn't quite worried that he might have been kidnapped by the minions of Satan, but I was getting a bit worried. He turned up again a week later. He was fine - much calmer than I'd seen him in a long time. He'd been driving up and down the East coast of Australia, sprinkling the ashes of this damn synth to make sure that it could never reform!

Re: [linux-audio-user] DeMuDi unusable on widescreen nVidia

by Jon B

> No. If you want to use DeMuDi, then install AGNULA/DeMuDi. You are asking for > trouble if you try to install it backwards like this. The main problem you > are likely to be experiencing with DeMuDi is that it doesn't support > proprietary drivers, so the nVidia support is limited. PlanetCCRMA/Fedora or > Mandrake might be more sympathetic to your hardware. Uh. That's what I did. And it's completely unusable. So I asked if there is an alternative way to get the same functionality. According to Agnula: "Q: Can I install A/DeMuDi over an existing Debian installation? A: Yes, at least as long as you are running Sarge. Follow the following steps" http://www.agnula.org/download/demudi/1.2.0-FAQ#Upgrading And according to something I read somewhere, Libranet can be used as an (easy) installer for a normal debian system. You just do a "minimal install" and then dist-upgrade to testing and all will be perfectly debian. Or so I read. (And can't find it now.) If another distro like Mepis can be used the same way, that would be good. I've tried the debian installer by itself and it was a nightmare.

[linux-audio-user] cmipci & 5.1 output via jack

by J�rgen A. Erhard

I have googled, search, tried the surround51.conf as .asoundrc, but whatever I did, I didn't get 6 writable inputs in jack. The cmipci is built-in on an ASUS A7V333. If anyone with that configuration has managed to get 6 channels in jack, could that person kindly share his (or her) config with me? A RTFM with a hint to the Fine Manual would be appreciated too. A "dummies guide to how to get 6 channels to show up in qjackctl" would be the best. Thanks for your help in advance.

[linux-audio-user] Re: Downloadable archive of the list?

by Juhana Sadeharju

Hello. One could browse sourceforge.net for audio projects. The projects often have a list of links to other audio projects elsewhere in the web. I recently downloaded all project lists on audio (and graphics) projects. It is a huge job to go through them systematically and check for projects which have not reached our ears yet. (Anyone want take letters n-z? I take a-m.) Of course, not every project is interesting for users, but for developers a good code can be found from any project.
