So.. exams gone OK this semester, so i'm returning to linux-audio world :) unfortunately my tascam us122 still dont work, and the new jack backend doesn't even compile to me.. dont know what to do.. but, since someone is using this thing right now on linux, i think there's hope even for me :) willy@Zeryn:~$ uname -a Linux Zeryn 2.6.10-mm3 #1 Wed Jan 12 21:01:17 CET 2005 ppc GNU/Linux willy@Zeryn:~$ cat /proc/asound/version Advanced Linux Sound Architecture Driver Version 1.0.8rc2 (Wed Jan 05 06:44:40 2005 UTC). willy@Zeryn:~$ jackd -d alsa -d hw:0 jackd 0.99.0 Copyright 2001-2003 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK compiled with System V SHM support loading driver .. creating alsa driver ... hw:0|hw:0|1024|2|48000|0|0|nomon|swmeter|-|32bit control device hw:0 configuring for 48000Hz, period = 1024 frames, buffer = 2 periods Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead Sorry.

[linux-audio-dev] linuxsampler crashing anyway

by Julien Claassen

Hi! I did try the following things to get current cvs to work. I used the appropriate configuration method and then edited the Synthesizer.cpp and exchanged "ASM_X86_MMX_SSE" with "CPP" as in the other synthesizer_mode functions. The sampler compiled cleanly. But when running it (with OR WITHOUT the --no-tune option) it crashes after a few seconds. It says: Zombified - calling shutdown handler. Then it keeps idling there. I have to use killall -9 linuxsampler to terminate it. CTRL-C doesn't work. Any idea. I use jack 0.99.47 (CVS from sunday. Is there anything I can do to help find this "bug?"? Some debug information, etc...

[linux-audio-dev] [ANN] liblo 0.16

by Steve Harris

Liblo, the Lite OSC library, is an implementation of the Open Sound Control [1] protocol for POSIX systems. It is written in ANSI C and released under the GNU General Public Licence. It is designed to make developing OSC applictions as easy as possible. http://plugin.org.uk/liblo/ Changes: Patch from Dave Robillard that fixes bundles of more than 4 messages. Some const char * for C++ compatibility. Added a source field to messages that represents the source from which a message was received. Useful in method handlers to determine which client sent the message. Added patch from Walco van Loon and Pix that fixes a bug in the hostname detection fallback code - Steve [1] http://www.cnmat.berkeley.edu/OpenSoundControl/

[linux-audio-dev] seeking minimal C++ library for ear-training

by Jeffrey Brown

Hi everyone. It's an honor to be read by you. I'm not a professional programmer, but I wrote some text-based C++ programs that quiz me on musical stuff, and was so pleased that I want to do something similar with musical tones. All I'll ever need is a library that will let me playback a sample at a certain set of frequencies -- like 6 at a time (bass tone, high tone, and a four-note chord) -- until keyboard input signals it to stop. In fact, even that's more than I need -- if playing a sample is hard, I'd be perfectly happy listening to square waves. I've looked at some audio libraries (OpenAL, Penguinsound, Sound Object Library) but they're all very intense, designed to do far more than I could even understand, let alone want. Is there a non-threatening, perhaps even easy-to-install, C++ library that will do what I have in mind? (In case it's relevant, I run Mandrake Linux 10.1 Official, KDE, ALSA, and an old Sound Blaster Live. I often go to the San Fernando Valley LUG, in Los Angeles, California.) Thanks in advance, Jeff __________________________________ Do you Yahoo!? All your favorites on one personal page � Try My Yahoo! http://my.yahoo.com

[linux-audio-dev] korg oasys

by Jens M Andreasen

Hi! There is an article on slashdot today about KORGs Linux based music- workstation christened OASYS. The java-script on KORGSs page kills my Mozilla (well, actually the whole Xsession goes bunkers ...) Is this machine somehow related to the prototype HiEnd keyboard Benno introduced a while ago? Price and features seems to be about the same ... -- ( ) c[] // Jens M Andreasen

[linux-audio-dev] [ANN] LACommunity goes gentoo...

by Arnold Krille

Hi all, if you are not a gentoo user stop here, otherwise read on. All the english linux-audio-lists please accept my apologies for crossposting to german gentoo list. [DE: Gentoo-user-de, bitte vergebt mir das Crossposting an die Englischen Listen.] Today I decided to make my little but constant gentoo-portage overlay available for the public. It contains only some apps not in already in portage. Currently available are aeolus-0.3.1 with aeolus-stops-0.1.1, fmit-0.9.[89], museseq-0.7.0, tuneroid-0.9.4 and (not an linux-audio-app) ktechlab-0.1.2. You can access the repository via svn, the address is: http://roederberg.dyndns.org/svn/apps/portage-arnold/ If there is interest, I could also create a tarball, just ask... Feel free to use it and feel free to send patches or to apply for write access. Currently I am trying to follow the anounces on this list, filter away the apps, where gentoo.org is fast enough and add the remaining into my repo. The chances are better if I personally use this app. :-) Thanks for your patience, Arnold PS: [EN: This will be the last time I do such a crossposting.

[linux-audio-dev] [ANN] QjackCtl 0.2.14 released!

by Rui Nuno Capela

Hi, QjackCtl 0.2.14 has been released. No big features, only a bunch of optimizations and cleanups. Check it out: http://qjackctl.sourceforge.net From the change log: - Put a limit on XRUN callback messages and statistics report rate, preventing the potential hosing of the GUI due to a XRUN cascade storm. The maximum reasonable report rate has been fixed to be one XRUN callback occurrence per second. - Set to ignore the SIGPIPE ("Broken pipe") signal, where available, as the default handler is usually fatal when a JACK client is zombified abruptly. - All conection view items are now sorted in natural case insensitive order, not just as audio port names as was before. - Got rid of those nonsense paranoid and rather stupid pseudo-mutex guards on the connections management framework and event notifications (nuff said :). - Optional confirmation warning on audio server shutdown, if there's some audio clients still active and connected (as suggested by Sampo Savolainen). - Check for <jack/statistics.h> on configure time (as of JACK 0.99.42+ CVS). - "Unlock memory" server setup option was added, allowing the release of memory used by common toolkit libraries (GTK+, Qt, FLTK, Wine) that were being superfluously locked on every GUI JACK client; number of periods has now the minimum allowed value of 2; server start delay widget converted to spinbox; setup dialog layout slighly changed. - Removed stand-alone usx2y driver support. Since JACK 0.99.41+ CVS, the special "rawusb" support on the Tascam US-122/224/428 USB Audio/MIDI interface controllers have been merged and properly integrated into the regular alsa backend driver. Being still experimental, this special mode of operation is now triggered only when "hw:N,2" is specified as the alsa device name (N = soundcard index of snd-usb-usx2y module). - Messages window limit is now enforced only when the line count exceeds in one third the user configured line count maximum; if Qt 3.2.0+ is in use, the QTextView widget is otherwise set to the optimized Qt::LogText format. - XRUN status items are kept double-dashed if none has been detected. Enjoy. -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

[linux-audio-dev] linuxsampler cvs from this weeks compile problem

[linux-audio-dev] Realtime audio and IO schedulers

by Florian Schmidt

Hi, i wonder if there's a way to grant a process priority over all other processes when it comes to disk i/o.. Somewhat similar like SCHED_FIFO scheduling for cpu priorities. This would be very useful especially for high reliability hard disk recording. I mean it would be simply great to record 24 tracks in ardour and not having to worry about disk underrun [or overrun] when a cronjob kicks in that scans the whole filesystem.. I heard and read a bit about the new io schedulers in the 2.6.x kernels, but i wasn't able to find any infos specifically on this subject.. So anyone knows more? Please let us know! Maybe current io-schedulers actually take the cpu priorities [nice level or relatime priorities] into account when assigning io bandwidth to processes, but if so i wouldn't know where to look to find out.. Thanks, Flo -- Palimm Palimm! http://affenbande.org/~tapas/
