[linux-audio-user] old booze, new bottle

by Dave Phillips

Greetings: I've put a new recording here : http://linux-sound.org/prelude.ogg The piece is not new, but this time I used ZynAddSubFX's lovely DX Rhodes 2 instead of my beloved TX802s. Zyn sounded so good I started seriously considering giving up my hardware synths. I may not go so far yet, but it's only a matter of time. Anyway, I hope you like the piece, it's just a brief instrumental sequenced in Sequencer Plus Gold and performed by that program running under DOSemu. Throw in Zyn and QJackCtl, and there you have it. :) More (new) stuff coming soon... Best, dp

[linux-audio-user] RME Digi96/8 PST and jackd watchdog timeout

by Ismael Valladolid Torres

I just bought a RME Digi96/8 PST soundcard and installed it on my computer. Once rebooted, info in /proc/asound/cards seems to be correct: $ cat /proc/asound/cards 0 [CK8S ]: NFORCE - NVidia CK8S NVidia CK8S with ALC850 at 0xfc001000, irq 193 1 [PST ]: Digi96 - RME Digi96/8 PST RME Digi96/8 PST at 0xfb000000, irq 201 2 [UM1 ]: USB-Audio - UM-1 EDIROL UM-1 at usb-0000:00:02.0-4, full speed I am forcing index numbers via /etc/modprobe.d/sound so mobo's internal soundcard is the default device. If I tell xmms to use ALSA and output hw:1,0, it works nicely and RME plays sound. But if I tell jackd to use that same output, it gets killed by the watchdog! 13:49:32.867 JACK is starting... 13:49:32.869 jackd -R -t10000 -dalsa -dhw:1,0 -r44100 -p256 -n2 13:49:32.880 JACK was started with PID=5961 (0x1749). jackd 0.101.1 Copyright 2001-2005 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 .. apparent rate = 44100 creating alsa driver ... hw:1,0|hw:1,0|256|2|44100|0|0|nomon|swmeter|-|32bit control device hw:1 configuring for 44100Hz, period = 256 frames, buffer = 2 periods nperiods = 32 for capture nperiods = 32 for playback 13:49:35.000 Server configuration saved to "/home/ismael/.jackdrc". 13:49:35.002 Statistics reset. 13:49:35.005 Client activated. 13:49:35.007 Audio connection change. 13:49:35.012 Audio connection graph change. 13:49:35.057 XRUN callback (1). 13:49:37.017 XRUN callback (169 skipped). jackd watchdog: timeout - killing jackd zombified - calling shutdown handler 13:49:38.023 Shutdown notification. 13:49:38.025 Client deactivated. 13:49:38.027 JACK was stopped successfully. cannot send request type 7 to server cannot read result for request type 7 from server It's the same no matter if I change frames/period, periods/buffer, priority, timeout, input and output channels, it's always the same. I'm finding pretty difficult to find a PCI slot in my mobo which allows me to use an isolated IRQ for the RME, if anyone thinks this could be the problem.. I am running vanilla 2.6.17 with Ingo Molnar's rt8 patches. I can post my kernel config if useful. Any ideas will be very welcome so thanks in advance.

[linux-audio-user] Linux Audio Notebooks for recording? Any recommendations?

by Michael Wagner

Hello, (Lurking mode off ;-) Trying to keep this short: Is it possible, in general, to do low latency multitrack-recording in ardour with a notebook and a multichannel audio-interface? If so, does anyone have any recommendations for notebooks and audio-interfaces that are suitable for this task and still available? I'd like to run gentoo-linux on it, do some recording and maybe, from time to time, do some Sequencing / Sample playback and PureData-stuff. Thank you, -Michael

[linux-audio-user] ANNOUNCE: Rosegarden 1.4.0 released

by Chris Cannam

ROSEGARDEN 1.4.0 RELEASED The Rosegarden team are delighted to announce the release of version 1.4.0 of Rosegarden, an audio and MIDI sequencer and musical notation editor for Linux. http://www.rosegardenmusic.com/ This is a particularly exciting release for the Rosegarden project. It includes a number of interesting new features, many of which we expect to build upon further in future releases. It also contains significant code contributions from a greater number of people than any previous Rosegarden release, including D. Michael McIntyre, Pedro Lopez-Cabanillas, Heikki Junes, Stephen Torri, Magnus Johansson, Vince Negri and Martin Shepherd as well as Chris Cannam, Guillaume Laurent, and a number of active translators. Significant new features include: * You can now record to multiple MIDI tracks at once from different devices and/or channels. * There is a new track parameter box which can be used to select the playback instrument for a track, recording filters, and the default parameters for new segments created on that track. * You can now create tracks identified with particular real-world performance instruments, so that new segments subsequently created on those tracks inherit the right clef, transposition and note range for each instrument (notes outside that range are displayed in a different colour in the notation editor). A database of around 300 instruments is included, courtesy of Erik Magnus Johansson of Eolin KB (http://www.kandav.com/eolin/). * The composition no longer has a fixed duration. In previous releases it was necessary to adjust the composition duration manually in order to record or create segments longer than the default duration. As of this release, the composition extends itself as you record or drag out new segments. * If you add a key change across multiple segments that differ in performance transposition, you can now choose to have the key transposed automatically for each segment. * You can now enter special directives in the notation editor that will be interpreted when creating LilyPond output, to achieve effects that are possible in LilyPond but not yet supported in Rosegarden (glissandi, arpeggios, segno/coda etc). * Soprano clef has been added. * Lilypond export now supports LilyPond 2.8 and has a new feature to merge multiple staffs as voices into one LilyPond staff, a new option to group staffs with a system bracket, as well as a huge number of bug fixes and performance improvements, which have tremendously improved the reliability and usefulness of the export engine. * You can choose to display the parameter boxes in a tabbed layout as an alternative to the default vertical stack. In the tabbed layout you can display a much greater number of MIDI controllers than was previously possible. * You can now cut, copy and paste "ranges" within a composition (cross-sections of all segments and tempo and time signature changes between two given end points in time). * There are new functions to split selected segments at an arbitrary time, and to split segments according to the MIDI device used to record them (which can be applied retrospectively to recordings made with Rosegarden 1.0 and newer). * The facilities for adding and editing markers (labelled positions in time) and setting loop ranges have been improved in a number of ways. * Tempos can now be "ramped" (smoothly changing from an initial to a final tempo over a period of time). * The tempo ruler has been overhauled and now permits in-place editing of the tempo map with the mouse (with undo and redo, of course). * You can finally zoom in and out of editing views using the mouse wheel (with Ctrl pressed). * The Panic function is now accessible from all transport toolbars. * When step-recording notes from a MIDI device, you can now enter chords simply by playing overlapping notes. * Rosegarden can now respond to MIDI Start, Stop and Continue system messages (as well as MMC/MTC), and send MMC Locate messages (as well as Play and Stop). For more information about Rosegarden and what it can do for you, please see http://www.rosegardenmusic.com/ Rosegarden is Free Software under the GNU General Public License. Chris

[linux-audio-user] Simplest MP3 player?

by Lee Revell

Hello LAU, What's the smallest and simplest command line MP3 player available? I need it for testing an embedded system. It must be cross-compilable for PPC target. The fewer dependencies the better (ideally it would be self-contained). Lee

[linux-audio-user] Qjackctl: Too many Writable Clients

by Ismael Valladolid Torres

When using qjackctl to launch jackd, in my list of writable clients I see 6 playback devices. I am using my mobo's internal soundcard which has only a stereo output. But if I check ALSA devices, information seems to be correct: $ cat /proc/asound/devices 0: [ 0] : control 1: : sequencer 16: [ 0- 0]: digital audio playback 18: [ 0- 2]: digital audio playback 24: [ 0- 0]: digital audio capture 25: [ 0- 1]: digital audio capture 33: : timer Why jackd registers more devices than those made available by ALSA? Any pointers? Cordially, Ismael -- Ismael Valladolid Torres "Il est vain de pleurer sur l'esprit, il suffit de travailler pour lui."
