by Lilli Chiffon

Hello people. After upgrading to debian lenny i had to remove my old version of xjadeo and try to compile a new one. ./configure is ok but when i type make, i've got a lot of errors, start by this one xjadeo.c:36:28: error: ffmpeg/avcodec.h: Aucun fichier ou répertoire de ce type xjadeo.c:37:29: error: ffmpeg/avformat.h: Aucun fichier ou répertoire de ce type "No such file or folder"= Aucun fichier ou répertoire de ce type. But i've got this file in /usr/include/ffmpeg/libavformat and /usr/include/ffmpeg/libavcodec Do you any idea of what's wrong ? I really need this small utilitie. Thanks, best regards P'tit Louis

band in a box alternative

by Jeremiah Benham

I was looking for a band in the box alternative. My idea so far is to use LeMMA as a front end to MMA. I am lacking a way to loop the chord progressions though. I think maybe a command line midi player that supports looping may work. I tried timidity in --loop mode but it pits a long pause after each loop. I also tried seq24 but I have to set up assign Alsa channels for each track each time. Is there a tight looping midi player or a band in the box alternative! Jeremiah

jackd, libasound_module_pcm_jack.so, custom pcm devices in asoundrc

by R Dicaire

Hi folks...Once upon a time, using Ubuntu Edgy, and rebuilding libasound2 plugins to include libasound_module_pcm_jack.so, I was able to successfully use skype with jack, using a custom pcm device specified in .asoundrc: pcm.skype { type plug slave { pcm "configvoip" } } pcm.configvoip { type jack playback_ports { 0 system:playback_1 1 system:playback_2 } capture_ports { 0 system:capture_1 1 system:capture_1 } } The sound card in question is an M-Audio Delta 44 (ice1712). The above configuration worked flawlessly, but due to issues with other sound applications using jack, I was forced to attempt various upgrades of jack, alsa, kernels, and even distributions. Eventually I settled on Debian Lenny, which includes the alsa jack pcm plugin by default, unlike Ubuntu, and now have few if any issues with jack-capable sounds apps. However, I cannot use skype with the above configuration on any consistent basis because for reasons unknown, when I make a skype call, and the alsa jack plugin is invoked, that thread may last a few seconds, the thread dies, and crashes jackd in doing so. Currently I'm using a custom RT kernel, 2.6.26.8-rt12-daw1, and stock versions of alsa*/jack* that Debian Lenny uses as of todays date. alsa-base: 1.0.17dfsg-4 libasound2: 1.0.16-2 libasound2-plugins: 1.0.16-1+b1 libjack: 0.109.2-3 jackd: 0.109.2-3 skype: 1.4.0.118 (yes, I tried 2.x and got same result) So, some questions. How would I go about troubleshooting the cause of the dying thread, and subsequent crashing of jackd? How do I determine the alsa version of the ice1712 driver used in kernel 2.6.28.8, alsa website shows 1.0.18a as current driver version. I can play 16 bit 44k1 wav files fine using aplay -D skype /path/to/file, from jack_lsp: alsa-jack.configvoipP.18769.0:out_000 alsa-jack.configvoipP.18769.0:out_001 Any thoughts, directions, etc would be greatly appreciated, thanks. -- aRDy Music and Rick Dicaire present: http://www.ardynet.com http://www.ardynet.com:9000/ardymusic.ogg.m3u

[ANN] Qtractor 0.3.0 (fluffy doll) released!

by Rui Nuno Capela

Merry season greetings! After a very long quarantine period, and while after the last Flirty Ditz romance, this pet has calmly bumped a few more steps ahead. Please welcome, my Christmas present to y'all, Qtractor 0.3.0 (fluffy doll) has been released! Same old intro follows: Qtractor is an audio/MIDI multi-track sequencer application, written in C++ on top of Qt Software's Qt4 framework, having JACK and ALSA as its main infrastructures and Linux as native and exclusive platform. Specially suited to the lone-wolf composer, arranger and (re)creative music-maker personal home-studio, it still hopes to evolve as a fairly featured desktop audio/MIDI workstation or at least, a prototypical part of it ;) Release highlights: * Paste-Repeat command. (NEW) * Punch in/out recording. (NEW) * Session/project template support. (NEW) * Current track auto-monitoring. (NEW) * MIDI buses now supporting multi-timbral instrument plug-ins. (NEW) * Individual clip gain/volume, normalize and audio/MIDI file export. (NEW) * Copy/paste to desktop environment clipboard. (NEW) * and many, many fixes and new bugs ;) Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball http://downloads.sourceforge.net/qtractor/qtractor-0.3.0.tar.gz - user manual http://downloads.sourceforge.net/qtractor/qtractor-0.3.0-user-manual.pdf Weblog (think upstream support): http://www.rncbc.org License: Qtractor is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Features: - Multi-track audio and MIDI sequencing and recording. - Developed on pure Qt4 C++ application framework (no Qt3 nor KDE dependencies). - Uses JACK for audio and ALSA sequencer for MIDI as multimedia infrastructures. - Traditional multi-track tape recorder control paradigm. - Audio file formats support: OGG (via libvorbis), MP3 (via libmad, playback only), WAV, FLAC, AIFF and many, many more (via libsndfile). - Standard MIDI files support (SMF format 0 and 1). - Non-destructive, non-linear editing. - Unlimited number of tracks per session/project. - Unlimited number of overlapping clips per track. - XML encoded session/project description file. - Point-and-click, multi-select, drag-and-drop interaction (drag, move, drop, cut, copy, paste, delete, split) - Unlimited undo/redo. - Built-in mixer and monitor controls. - Built-in connection patchbay control and persistence (a-la QjackCtl). - LADSPA, DSSI and native VST plug-ins support. - Unlimited number of plug-ins per track or bus. - Plug-in presets, programs and chunk/configurations support. - Audio/MIDI clip fade-in/out (linear, quadratic, cubic). - Audio/MIDI clip gain/volume, normalize and export. - Audio clip time-stretching (WSOLA-like or via librubberband), pitch-shifting (also via librubberband) and seamless sample-rate conversion (via libsamplerate). - Audio/MIDI track export (mix-down, merge). - Audio/MIDI metronome bar/beat clicks. - MIDI clip editor (matrix/piano roll). - MIDI instrument definitions (a-la Cakewalk(tm)) - JACK transport sync master. - MMC control surface enabled. - Configurable keyboard shortcuts. Change-log: - Almost complete rewrite of the plugin configuration and parameter initialization logic. - MIDI bank/program selection is now taken into account on plugins initialization and replication. - Fixed initial parameter values for native VST plugins. - Track form plugin lists are now properly (re)initialized when track type changes. - Generic plugin forms now have the option to show/hide the parameter widgets through the new "Params" button. - New auto-monitor toggle option (menu Track/Auto Monitor): the current selected track is now set on monitor and MIDI channel omni-mode automagically, as a convenient workflow feature (kindly suggested by Holborn). - MIDI clip editor Tools menu is not disabled anymore when there's no selection, drop-down menu items are instead. - Make all recorded clips to honor either the punch-out or play-head accumulated position; resolve all pending MIDI sequence note events on record stop/close. - Major silent move: audio plugins chain are now applied in a pre-fader/meter basis as is usually implied from the mixer strip layout ie. signal flows from the top to the bottom. - All MIDI buses may now have plugins inserted so that multi-timbral synth/sampler plugins get driven to their fullness. - MIDI track plugin's dedicated audio output bus may now be effective, as it seems, good old master audio output bus was being used, no matter what. - Paste-repeat command has been introduced, now allowing to replicate and concatenate the clipboard contents over the time-line, with a given repeat-count and optional period (see menu Edit/Paste Repeat... on the main and MIDI clip editor windows). - Normalize tool on MIDI clip editor got rewritten from its previous brain dead, useless and utterly wrong operation. - All time offsets and lengths are now zero-bar/beat based when displayed in the BBT (bar.beat.ticks) format. - MMC STEP gets adjusted to current snap-per-beat setting. - Fixed broken initial buffering that was randomly crippling those audio clips that fit integrally in cached and while on playback. - Fix initialization of multiple instances of DSSI plugins which implement run_multiple_synths (eg. fluidsynth-dssi), preventing an instant crash on activation. - Exclude deprecated VST elements from compilation. - Export tracks dialog has new punch in/out range option. - Somehow realized that looping and punch-recording are two mutually exclusive states, at least until loop recording (ie. takes) gets real. - Fixed bug #2249291 - Crash on tempo change; affecting the WSOLA based time-stretching on all non-stereo audio clips. - Incomplete audio peaks were being cached prematurely, fixed. - Make way for paste/dropping items from the system clipboard over the main track view. Cut/Copy/Paste/Delete of file items have now this workaround fixed, wrt. Files widget keyboard shortcuts, respectively. - Clip gain/volume propriety is now in place and reflected in audio clip waveform drawing in particular. - A new hideous progress bar is now lurking in the main status line, as found convenient to display progress of the also new clip tools (normalize, export, etc.). - Clip normalize tool is now available (Edit/Clip/Normalise). - Audio and MIDI clip file export is now available as a tool (see Edit/Clip/Export...). - Punch in/out (range) recording is now in experimental shape, with minimal settings and functionality, already accessible through the main menus, transport toolbars and visible on main tracks view and MIDI editors as magenta colored line markers. - External MIDI control events for channel volume (7) and channel panning (10) are now handled properly through session tracks. - Session file templates make its debut with new usability option, on whether new sessions are created based on existing template file (see View/Options.../Display/Session/New session template; nb. session templates are just regular session files but loaded and saved with no media content (no clips nor files). - Grayed/disabled palette color group fix for dark color themes. - Implicit attempt to flush all pending notes for some, if not most plugin instruments (eg. VSTi), on playback stop. - Fait-divers: desktop menu file touched to openSUSE conventions. - Internal refactoring alert: Session and Options instances are now being redesigned as singletons, preparing to get out of the way from the master GUI/MainForm instance. - Clip drawing methods refactored so let the fade-in/out handles get seen with transparency over the clip graphics content. - Reset and continue looping even still when continue past end transport option is not set and playback is rolling. Hope it makes through a Happy New Year with flying colors ;) Cheers && Enjoy! -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

place to share and give away music?

by Nils Gey

Hi list, After my little Album is sold out I want to give it away for free now. I will choose one of the CC licenses I think so that people can share,download, listen, play-back (even commercial) to it unlimited and free of charge but that they are prohibited to change, remix, rent or sell it. Now I want to share with a big audience so do you know any sites and places where I can share under the terms I've mentioned before? Nils
