Hi folks; For the third time in about 20 hours, rosegarden has locked the system up totally, requiring a hardware reset to reboot. All 3 times it was playing a song. System is a quad core AMD phenom at 2.1 Ghz, 4Gigs memory, rosegardens midi output directed to the midi synth built into an Audigy2 Value sound card installed in an ASUS M2N SLI Deluxe mobo. OS is pclos-2011 and up to date as of about midnight last night. Kernel is a pclos supplied version of 2.6.38-2, using Con K's bfs scheduler. Realtime feel for the desktop. :) rosegarden is version: Rosegarden version: 11.02 ("Claire de Lune") Build key: 34a6ea6dff Built against Qt version: 4.7.0 Qt's libs in /usr/lib say they are 4.7.3 Zero messages made it to the logs, its a total freeze. Take rosegarden out of the scene and uptimes for this machine have been in excess of 30 days. Generally, pclos has been a _very_ stable release. Can I dig up and supply any other info that might be needed here? Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

[LAU] [ANN] Qtractor 0.5.2 - The Charlie X-ray gets through!

by Rui Capela

Aha, TYOQA is finally coming to an end. Are we getting 'pre-beta' status? No way. Not there yet. And quite frankly, it will never be. As most of you who know my stance on this alpha-and-omega-thing, may well rejoyce: this is alphaaaaa!... Now, let's get some more cynicism to the extreme, an activity that I've been criticized more than often: the previous dot release nailed the day when a bitten-fruit boss passed away. I am no prophet, but could it be that we're witnessing the dawn of a brand 'new-age passover'? I wonder what will happen this time. Let's get over it, or better said, through it! Time will tell or else, never mind. Qtractor 0.5.2 (charlie x-ray) breaks out free! This solstice release comes with a long overdue loop-recording/takes 'featuritis' breakout. As a matter of fact, it is actually the relevant feature being introduced this season. BTW, happy holidays--before's too late ;) Well, I've tried to do something barely useful, at least for the lone, one-(wo)man-band and over-dubber, that is. There's still a point on the old motto, remember? That 'techno-boy(gal)-bedroom studio'? Now I think he/she can have a guitar ;) In other words, I'm not really sure this is going to be the best user-interface or paradigm, model, whatever. You tell me :) Release highlights: * Loop-recording/takes implementation (NEW) * Default session file format option (NEW) * LV2 State extension support (NEW) * Options dialog re-arrangement (FIX) * Improved in-flight recording display (FIX) * MIDI clip file revision numbering (FIX) * Clip "Unlink" option (NEW) Cheers!

Change-log: - Fixed a probably old lurking destructive bug, which was incidental to when an invalid or non audio file is imported, intentionally or by mistake, into new or existing audio clips (eg. importing a MIDI file where an audio file is expected). - Force audio file closing to occur on the very same disk-write (sync)thread, possibly mitigating an old random crash issue lurking in the vorbis reference encoder (recording) re. the non thread-safetyness of the vorbis_analysis() final call. - Fixed extraordinary shadow-playback of audio clips which extent were longer than the respective audio file length. - Default session file format option now promoted (see View/Options.../General/Session) in the way of whether file suffix gets honored upon session open or save (.qtr, .qts or .qtz). This brand new option also applies for default state file format on a JACK-session salvage context. - The View/Options... (aka. user preferences) dialog sees a new arranjement in layout, with some options moving into this brand new tab page called General. - LV2 State extension support has been added, which shall replace old LV2 Persist extension interface in the near future. It also replaces the LV2 Files extension from now on (thanks to Dave Robillard). - Dirty MIDI clips are now auto-saved when MIDI track properties get changed through its own dialog. - Fixed one probable too old crash when cancelling a new/add track dialog. - MIDI SysEx event list editing is now fixed. - Once again, make sure all recorded clips start and end at the very same position when multiple track recording is turned on/off, while playback is still rolling. - Fixed Makefile.in handling installation directories to the configure script eg. --datadir, --localedir. - Possible attempt to improve in-flight recording clip display, especially when looping and MIDI clips are involved. - MIDI clip revision (re)numbering paranoia has been improved as much to avoid MIDI file clashes as much as possible while editing multiple MIDI clips which reference the same SMF and track/channel. - Creating new or updating existing buses with exact same names of any current dedicated inputs/outputs (which are implemented as special covert buses) is now disallowed (preventing bug #3430406). - Loop-recording/takes functionality is now ready for the masses and accessible from brand new Clip/Take menu (Select, First, Previous, Next, Last, Reset and Range...; the latter is actually being provided as bonus feature :) as to fold any given clip into so-called takes, simulating loop-recording mode over an arbitrary range). - Loop-recording/takes infrastructure integration is sneaking in: all clips recorded under a loop/cycle range may now get split (folded) into one or more so-called takes. A new option is now provided, as to select which take is about to retain after the recording ends, either the First or the Last one. Just turn this mode off (None) and keep with the old recording behavior, where clips are laid out unfolded through the timeline, as usual (see menu View/Options.../Display/Loop recording mode). - Improved robustness in face of disabled audio buses when global maximum number of JACK (audio) ports is surpassed (mitigating bug #3421911). - Improved single-track clip selection status logic (possibly fixing bug #3419141). - Clip/Unlink action is now available for detaching linked/ref-counted MIDI clips, renaming and saving into auto-incremental SMF filenames. - Temporary session archive directory now (pre)fixed whith program name (eg. /tmp/qtractor). - Fixed VST GUI editor window title on first show. - Fixed build for ancient VST-SDK 2.3 (32bit only). Enjoy! -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

[LAU] Rosegarden -> lilypond help

by gene heskett

Greetings everybody, midi folks in particular; I have a .mid file that plays using the wrong instruments because it was composed before GM. Sent to the built in synth in an audigy2, it plays at normal speed but wrong instruments. Loaded into rosegarden (to fix this), it plays at about 1/100th speed. This doesn't surprise me too much as the originating program dates to 1991 on a TRS-80 Color Computer 3 & GM was something we only got in the then brand new Sound Canvas's and such. Obviously something in the header doesn't meet .mid file specs. I did change the internal name from .ume to .mid in a hex editor, and reloaded but other than the track title now showing the correct string, no other effect. In an effort to see what might be wrong, I fired up the print preview which uses lilypond to generate the 'sheet' music. But from the looks of it, its going to use 80% of all 4 cores of this phenom for several hours to render, probably because of this same time error, (transport says its like nearly 3 hours long, but its a bit over 3 mins in actual play time) so the generated pdf is likely to be 40Gb! Does anyone know enough about this to tell me where, in rosegarden, to fix this? Or do I need the hex editor again? Or, heaven forbid, its a bug in rosegarden (shudder). Thanks midi folks.

[LAU] Help with amateur radio setup

by Ali Polatel

Hello, I and a couple of friends have decided to set up an amateur internet radio. We have a relatively small budget thus we want to go step by step. What we've thought so far is to have a devoted box with all the music archived. Ideally we want to make the interface very simple for DJs to use, even if this means increasing the maintenance cost of the system administrator. They should be able to grab a microphone and use a portable interface (yes, some DJs may be using windows) to choose music, play and start talking right away. The devoted box will be running Linux and I plan to administer the system. I have relatively good knowledge on Linux systems and programming in general. I want the system to be flexible, be it at the cost of difficulties in configuration or deployment. Please advice and share your experiences. -alip

[LAU] Three Variations (new Csound piece)

by Dave Phillips

Greetings, A new piece created with AVSynthesis (audio by Csound) : http://soundcloud.com/davephillips69/three-variations Beyond a wholesome discipline, no samples were harmed or otherwise damaged during the composition of this piece. Also, with reference to recent discussions here on LAU, I must point out that not a shred of originality attaches to these variations. Every effort was made to remove any and all hints of self-expression. Further, not one moment of this music is suitable for public airplay - restaurants, cafes, bistros, diners, gun shops, libraries, etc - with the sole exception of the DeGaulle airport. Parental discretion advised. Not suitable for minors or unaltered majors. Best, dp

[LAU] ANN: pd-l2ork Holiday release now available

by Ivica Ico Bukvic

Greetings fellow FOSS/Audio enthusiasts, It is my great pleasure to announce pd-l2ork 20111215 a.k.a. Holiday release. In the latest version of Linux Laptop Orchestra's in-house version of Pure-Data we've squashed a number of lingering bugs, as well as added some exciting new features, including: *infinite undo that covers all editing actions (while some externals with custom dialogs may require minor adjustment to their code to work with the newfound undo, most of them will work out-of-box). *more robust paste from external clipboard. copying pd scripts from an email and pasting them directly into a canvas has never been easier. *multiple entry bug that has been plaguing pd for years has been finally squashed. *resizing GOP window via gui (just like the rest of iemgui objects). *a number of usability improvements in terms of pasting logic and other editing features (e.g. gop resize via gui now prevents users to make it smaller than its text size unless hidetext is enabled, objects are automatically resized (except for gop objects with hidden text for obvious reasons) to accommodate adequate spacing for inlets and outlets, etc.) *all known graph-on-parent redraw issues have been addressed and gop redrawing is now as robust as it has ever been. *and many more... (see Changelog and git logs for more detailed info) If interested, head to http://l2ork.music.vt.edu/main/?page_id=56 to download 32-bit builds, source, and more.
