I'm looking for some kind of midi processor that would allow me to convert midi input (from a controller) into some other midi output (to gear) so that I can workaround the limitiation of my faderfoxes that have all midi pre-wired. Would there be an application like that is lightwheight enough I could run it on my EEE ? Thanks for any pointers Marc

controlling dssi parameters from keyboard?

by James Stone

Hi there, I am currently using the excellent whysynth with ghostess. Does anyone know of a way I can assign different midi controllers to different parameters for real-time editing? I am also trying to work out the most efficient way to do a keyboard-split? I guess running 2 instances of ghostess might be the best. James

Re: [LAU] realtime problem on 2.6.25

by Ben Tartsa

Hi Tim, seems no patchset has been released yet for 2.6.25 See here: http://www.kernel.org/pub/linux/kernel/projects/rt/ So I would say stick w/ the 2.6.24 series for now. Hope this helps.

Interest for localized linux audio wikis ?

by nradd

Hello, In the name of all the co-admins of www.LinuxMao.org, wich is a Tikiwiki [1] web site, I would like to know if there is an interest for any kind of collaboration in the field of (pirmarily) non-english Linux audio wikis ? Sometimes ago one of our members, who is multilingual, expressed the wish to translate ours pages in german and spanish, which was favorably received by other members, later a polish user asked to translate part of our content for his own site (BTW, everything is under CC share alike license and there is no need for authorization). Then started the idea to ask here if there are other non-english people who want to involve themselves in the same kind of site but in their own native language. Either imitating us or cloning our "concept". It's been 3 years that we run "Linuxmao" and we have reached over 1000 members (MAO stands for Musique Assistee par Ordinateur=Computer Aided Music). As non english linux users, we do have the need of reappropriation of all the english resources on the net. This has turned into a website specially aimed at easing newbies's life, as well as sharing various original infos for our advanced users. Our contents are not really encyclopedic but deal with a selection of the best applications for which we try to provide up to date informations and quick starter guides. Our site is not only a wiki, there are some forums, a megaphone (which is a quick chat box that adds some life), a news section that often pick up the news from LAA, an IRC channel on freenode (#linuxmao) and recently we started a collaborative Open CD project (files are shared via bittorrent). Well, this is a community web site. :) At the moment most of our articles are not yet complete, after all a wiki is an ever evolving thing and will be never really finished. But for sure it's been a very satisfying experience seeing this site evolving constantly with new interesting members arriving with fresh ideas. It would be great to share this to a higher (transnational) level. So, the intent of this mail is to ask several questions here: * Are there already some non english sites, specially in Spanish or German, about audio and computer music under Linux ? If not, are there some people here who would want to start one ? * Would there be some interest to create a webring, some sort of collaboration between all of theses (possible) sites ? * Then, what could be this collaboration (we have a member that has written scripts to handle properly the translation of the Ardour manual, for instance). * Would it be pertinent to envision an user centric english site, wich could serve as the reference and the source for all the localized versions ? And, as theses kind of community sites provide forums wouldn' it help to gather a broader audience, given that mailing lists like LAU (yet great) lack a little of usability and accessibility ? * Is there an interest for Tikiwiki as the CMS technology ? It would be possible to collaborate at this level too, sharing tricks and improvements. We are thinking about sharing a starter kit with already set up various modules so that people who would want to adopt TW will quickly get a working site like us. Best regards, N.R.

[ANN] jack-smf-utils 0.9

by Edward Tomasz Napierala

Jack-smf-utils is a set of two utilities - jack-smf-player and jack-smf-recorder - whose purpose is to play and record MIDI streams from/to Standard Midi Files (i.e. the files with .mid extension) using JACK MIDI. There is also smfsh, "SMF shell" that is kind of interactive, command line SMF files manipulation tool which started its life as a debugging aid. And finally libsmf, C library for loading, writing and manipulating the contents of SMF files. http://pin.if.uz.zgora.pl/~trasz/jack-smf-utils/jack-smf-utils-0.9.tar.gz -- If you cut off my head, what would I say?

Freecycle compile errors

by Christian Delahousse

Hello once again guys! I was wondering if you could help me with a problem I'm having with Freecycle. I'm trying to get it to compile to no avail. I've also tried to install the debian binary (even though I'm running Ubuntu Studio Gutsy) but it still won't install since the ubuntu binary installer says I don't have libc6 which I do have installed, including libc6-dev. I also have a buncha qt3-qt4 core packages installed These are some of the errors I'm getting with the make command (after it tells you to use the qmake command). freecycle.cpp:1194: error: within

Hardware latency of firewire controller

by Ismael Valladolid Torres

My colleague bought a Presonus FP10 firewire audio interface, which reports working nice in Linux. Moreover he owns a firewire controller made by Sunix with a Texas Instruments chipset. He tells us that for having jackd working without xrun and no other artifacts he needs to use 512 frame/periods, then latency is 34ms, which could be considered awful as this card is able to work with 2ms latency using other operating systems. He checked IRQ and saw that the firewire controller shared IRQ with the network interface. Check out output of lspci -v . 03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01) Subsystem: Giga-byte Technology Unknown device e000 Flags: bus master, fast devsel, latency 0, IRQ 17 I/O ports at a000 [size=256] Memory at eb000000 (64-bit, non-prefetchable) [size=4K] [virtual] Expansion ROM at 50000000 [disabled] [size=64K] Capabilities: <access denied> 04:01.0 FireWire (IEEE 1394): Texas Instruments TSB43AB23 IEEE-1394a-2000 Controller (PHY/Link) (prog-if 10 [OHCI]) Flags: bus master, medium devsel, latency 32, IRQ 17 Memory at ec004000 (32-bit, non-prefetchable) [size=2K] Memory at ec000000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> lspci lists 18 devices and every one of then reports 0 latency except the firewire controller. And hardware latency is 32ms, very near the 34ms of audio latency reported by jackd. So one could think that if the firewire controller added no latency, audio latency could be as low as 2ms. Strange, isn't it? So it looks that audio latency achievable by jackd is limited by hardware latency achievable by the firewire controller. He even tried locating a PCI slot that doesn't share IRQ and running the kernel with the noapic and nolapic options so the system ends reporting the sound card in the IRQ 11, which is nice. No change, hardware latency is 32ms in any case. marcel@ubuntu:~$ uname -a Linux ubuntu 2.6.22-14-rt #1 SMP PREEMPT RT Tue Feb 12 09:57:10 UTC 2008 i686 GNU/Linux Anything else can be tested? Or should he put back the PCI firewire controller and buy another? Which one? Any ideas welcome. Personal answers not to the list also welcome.

audio-cd ripping and burning with conditions...

by Julien Claassen

Hi everyone! Certainly not new, but still... I want to rip an audio-cd, with it's absolute track-spacing and everything you can hear and I want to burn it that way. My burning-tool of choice is: cdrecord. My cd-writer is installed as an ide-device. I want to preserve the track-gaps and if there are non, I want to preserve the direct bl3ending from one track to the next. How can I manage? NOTE: I need text-oriented tools only! Thanks for any good advise inadvance!

EU + USA tour!

by Chris McCormick

Hello, (apologies if you recieve this more than once) My wife and I are doing a tour of Europe (in a campervan) and the USA starting at the end of August and I'm trying to organise some gigs for myself. I'm counting on the help of you good folks of the Free Software music oriented lists! I hope you'll excuse the imposition. I've written up a bit of a bio[1] and you can download demo tunes from my music website - see the links below for a selection. Finally, I've put up a tour page on my music site, so please check it out if you're at all interested in having me play at your event or venue, and please feel free to forward this email to anyone you know who might book experimental electronic/dance music. Here is the tour information: <http://sciencegirlrecords.com/chr15m/page/tour> Please contact me off-list if you are interested. I will be updating the tour page with dates, as I get them. Thanks for your time. Best regards, Chris.
