[ANN] Qtractor 0.5.1 - The Bravo Yankee return!

by Rui Nuno Capela

Howdy, Summer is now long gone, obviously fall has already begun. As winter looms on the horizon the year steadily marches into its due end. (oh crap!...) Today marks the day of this second public release while on the TYOQA age. It also marks yet another birthday of mine. One more year's gone, one less to go. Be happy! I hope you'd like my party as soon you get over from yesterday's bitten fruit showtime. Now's the time... Qtractor 0.5.1 (bravo yankee) is out! Yes, it's "bravo" alright, not "beta" nor anything else. Despite any previous existing codename. Now, it's all dumb-down easy to predict any next release codenames, a matter of convergence and fact that just chalks one less of a burden on me :) Believe it or not, this is the best and, allegedly, the most stable release ever. Ain't them all? ;) Release highlights: * Linked (aka. ref-counted) audio/MIDI clips (NEW) * Aux-Send pseudo-plugin (NEW) * Direct-access plugin parameter slider (NEW) * MIDI file player (NEW) * Automatic time-stretching of audio clips on tempo-map changes (FIX) * Improved native Linux VST support (FIX) * Improved JACK-Session support (FIX) * Improved generic plugin form (FIX) * MIDI-fx plugin support (NEW) * Audio bus/ports auto-connect option (NEW) * First translation call (Czech) (NEW) Cheers!

Change-log: - More LADISH support: SIGTERM signal is now trapped for graceful application close. - Improved paste-repeat snap precision when dealing with large repeat counts. - Czech (cs) translation added, by Pavel Fric. - Added a few snap-to-beat divisors (unusual Beat/5, Beat/7, Beat/9 and Beat/10) for completeness sake. - Such a simple change of mind with a visual twist: the "A" track automation button/menu has now been - moved to the right-most, as it belongs ;) - Auto-connection of dedicated audio outputs is now optional for default audio master bus, metronome, player and MIDI instrument plugin dedicated audio outputs. - Finally, after a pitiful large brain-dead period, generic plugin forms are now showing all possible controllable plugin parameters featuring a paged, tabbed dialog, whenever applicable. - Special hack/fix for JUCE based native VST plugins, which are the most actually found with a GUI editor, skipping explicit shared library unloading and thus avoiding some mysterious crashes on session close and/or application exit. - Support for MIDI-fx plugins (native VST and/or LV2) is now implemented and functional (intra-chain only). - Instrument plugin bank/program selection was found broken or dead in the water, specially on VSTi, now finally fixed again. - VST plugin parameter value display on generic form is now back in business (were dead regarding value changes). - All plugin's provided GUI editors are now honored by being popped up first, instead of the usual but good old generic plugin form. - Long overdue implementation of a dedicated MIDI file player is now accessible from the MIDI files widget; one can play the whole SMF or just a single track or channel. - Update to a newer VeSTige header, probably fixing an old 32 vs. 64 bit mismatch. - Avoid JACK session filenames/paths to be ever shown; also avoid all buses ports (re)connections when JACK sessions are (re)loaded, given the fact that session management will take care of just that; more also, untitled/default session names are now also picked up to match current LADISH project name, obviously given by LADISH_PROJECT_NAME environment variable, whenever present (as suggested by Nedko Ardaunov). - Paste-repeat floating selection has been fixed (was showing only the last repeated selection). - Coherence of tempo changes on audio and MIDI clips, whether automatic time-stretching is in effect, has been slightly improved, hopefully fixed. - Bold attempt to get linked (aka. ref-counted) audio and MIDI clips into practice (EXPERIMENTAL). - Main track view now showing all clips above the grid. - Added support for both new and older (deprecated URI) lv2_external_ui extension (by Nedko Ardaunov). - Following yet another great idea, and implementation, by Holger Dehnhardt, who already brought us the new aux-send insert plugin, thanks again, the so-called direct access control option is now featured for any plugin parameter right from plugin listings eg. mixer strips. - General resource consumption and management has been slightly improved, due to internal buses allocation optimization. - Fixed nasty crash-bug that was severely affecting all sessions that had at least one insert (pseudo-)plugin on any audio input bus. - All automation curve nodes are now relocated whenever disparate session sample-rate is detected on load. - New aux-send/insert pseudo-plugin is now introduced, allowing to route any track audio output to any other audio output bus besides the nominal one -- thanks to an original implementation from Holger Dehnhardt. - New immediate edit/loop-range settings from current clip extents, accessible on the main menu (Clip/Range Set, Loop Set) and from MIDI clip editor menu as well (File/Range Set, Loop Set). - MIDI Names XML files (*.midnam) may now be imported into MIDI instrument definitions. (EXPERIMENTAL) - Avoid cursor reset while editing MIDI events list (fixes bug #3380259, reported by Frank Neumann). - Just some typos fixing (patch #3378382 by c-korn). - Track view automation curve editing mode has been slightly fixed, now allowing for other previously existing point-and-click mouse operations. - Default automation curve mode is now preserved (following a suggestion by Alexandre Prokoudine, thanks). Enjoy! -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

[OT] Program now online - International Conference on Spatial Audio, Nov 10-13 2011, in Detmold, Germany

by Jörn Nettingsmeier

Hi *! The timetable for the International Conference on Spatial Audio 2011 in Detmold/Germany is now online: http://www.icsa2011.org/vdt/webdownloads/icsa2011/ICSA_Program_Schedule_201… The conference emphasizes the scientific and technical aspects of spatial audio, but a number of workshops and presentations will be devoted to the artistic and esthetic possibilities and challenges as well. In addition to five structured sessions on various spatial audio topics, the conference will feature installations of WFS + Height, Auro-3D, Binaural and Higher-order Ambisonic systems. During a three-day recording session last week totalling more than 140 microphone signals, we have recorded several chamber music ensembles simultaneously for all those methods and will offer conference participants a first-hand opportunity for comparison. Complementing the two fixed WFS installations available in Detmold, an additional temporary 40-speaker setup will be rigged for WFS and Higher-order Ambisonics reproduction, and one seminar room will be equipped for 9+2 channel Auro-3D playback. Registration is now open. Best regards, Jörn

Internally representing pitch : A new approach

by harryhaaren＠gmail.com

Hey Everybody, I've been thinking about the "best" way to represent tonality & pitch in software. AFAIK most software implements thier "internal workings" as MIDI messages. This seems a clean easy solution, pass around 3 values and the whole Engine is sorted. But what if one wants to expand on the possibilities of MIDI, and not confine oneself to the 127 notes that are available, but rather allow the use of *any* tuning, pitch or scale. Scala seems pretty much designed to handle this kind of situation, and while I can read the example .scl files, I can't find any example "host" or simple example program to guide me along in how to use it... So that's the question here really, how does one go about it? -Harry

jack session compatible applications?

by m.wolkstein＠gmx.de

hi, i am interested which jack supporting audio applications currently also support jack-session. http://trac.jackaudio.org/wiki/WalkThrough/User/jack_session holds a list, but i think it is a bit out dated. imo, it would be nice, if involved linix audio devs would add her jack-session application to this email. a really easy way to collect a list of this apps. i am involved in hydrogen so this is why i add only this application to this list. greetings and thx in davanced, wolke list of jack-session supporting applications: * hydrogen0.9.6 (svn head)

calling zita-convolver users

by Fons Adriaensen

Hello all, A new release of zita-convolver is being prepared. It's currently in the 'torture department' for testing, and it will remain there for a week or so. There are quite a lot of changes. The new release will not only be binary incompatible with 2.0.0, there will be some small but unavoidable API changes as well. This also means there will be an update of jconvolver at the same time. If you are one of the brave using zita-convolver in your own project even if there was no documentation at all, please get in contact. I will then provide the new library along with instructions that should allow you to provide a compatible source version of your app at the same time as the library update. Ciao, -- FA

RDF libraries, was Re: [ANN] IR: LV2 Convolution Reverb

I couldn't see it in a quick browse on your SVN server. I have a library (Dataquay, http://code.breakfastquay.com/projects/dataquay -- preparing a 1.0 release of it at the moment, so if anyone wants to try it, go for the repository rather than the old releases) which provides a Qt4 wrapper for librdf and an object-RDF mapper. It's intended for applications whose developers like the idea of RDF as an abstract data model and Turtle as a syntax, but are not particularly interested in being scalable datastores or engaging in the linked data world. For my purposes, Dataquay using librdf is fine -- I can configure it so that bloat is not an issue (and hey! I'm using Qt already) and some optional extras are welcome. But I can see the appeal of a more limited, lightweight, or at least less configuration-dependent back-end. I've considered doing LV2 as a simple example case for Dataquay, but the thought of engaging in more flamewars about LV2 and GUIs is really what has put me off so far. In other words, I like the cut of your jib here. Chris

JACK 0.121.3 released

by Paul Davis

JACK 0.121.3 is a bug fix release containing (almost) no new functionality. It is required if you want to use JACK1 on OS X with any clients that use weak linkage for JACK feature detection (e.g. Ardour). Changes: * Make the printed output of jack_iodelay more useful to actual users * Compilation fixes for OS X (particularly PPC architectures) * Remove SSE-related messages during startup * Fix a few argument type declarations for a few functions * OSS backend: fix a call to yet undefined engine instance http://jackaudio.org/downloads/jack-audio-connection-kit-0.121.3.tar.gz

linuxaudio.org network outage

by Robin Gareus

Hi all, There is currently some network problem affecting the vt.edu uplink which hosts linuxaudio.org. We do not yet know the details and the issue is outside of our scope but the Virginia Tech Admins are on to it. Apparently low bandwidth requests - such as email - still make it through occasionally. We're sorry for the inconvenience. greetings, root(a)linuxaudio.org

AMS to Ingen: VC to PCM

by Aurélien Leblond

Hi everyone, I'm porting the AMS internal modules to LV2 plugins to be used in Ingen. Small problem is, AMS uses VC (even the output of the VCOs that produce sound) when Ingen uses PCM... So far, my research seems to lead that a simple multiplication by 16 of the VC output should convert it to PCM, and vice-versa. That doesn't seem right though, as I would think the sample rate should be involved in this conversion! Would somebody have any ideas? Thanks in advance guys, Aurélien

RME Multiface/Digiface/RPM testers needed

by Adrian Knoth

Hi! Back in July, I've hacked a bit on the hdsp driver to fix the RPM support. Those of you who own a Multiface, Digiface or RPM: Could you give http://adi.loris.tv/hdsp-test-20110925.tgz a whirl? I just want to make sure the RPM fixes don't introduce any regression, so if your Multiface/Digiface was working fine before, I hope nothing changes. If you own an RPM, the box should be detected automatically now. I've verified it with my Cardbus based Multiface so far, but I'd love to have a broader test phase before sending the patches upstream. TIA -- mail: adi(a)thur.de http://adi.thur.de PGP/GPG: key via keyserver
