Just a couple of days since 2.8.8, and Ardour 2.8.9 is available from http://ardour.org/download Why? It turned out that the infamous mute bug (which caused the mute button to do nothing) was actually not fixed in 2.8.8 (or prior versions where this has been claimed). This has been one of the worst regressions of recent versions of Ardour, and I mistakenly blamed packagers and distributions for it. Thankfully ardour.org member the_CLA spent time with me on IRC and we finally proved to my satisfaction that the bug was really in Ardour. Its now fixed, hopefully forever. In addition, a new Ardour user on OS X pointed out two rather unfortunate problems that have now been fixed: * If a plugin has existing presets, the preset selector in the plugin editor window would steal key events, possibly causing an unintentional (and unrecoverable) reset of the plugin state (very annoying) * All canvas items except for the text used to label and regions could have their color adjusted. These two exceptions have now been added to the set of things that can be tweaked by, for example, a color-blind user, or someone who just wants dark colors for tracks and white text on region names. Many thanks to the_CLA and Maurits Lamers for patiently getting me to understand these 3 bugs.

Ardour 2.8.8 is released

by Paul Davis

Finally, its June and Ardour 2.8.8 is finally here. Although this is primarily a bug-fix release, some of the "bugs" fixed are so pervasive and significant that they could almost count as new features. In particular, automation editing has finally arrived at a place that people with experience on other DAWs may consider actually usable. Issues with alignment of new and existing recorded material are addressed too, and there are lots of other bug fixes for issues small and large (including 3 or 4 crashing bugs). Thanks to motivation provided by the Mixbus project, there are also yet more improvements to AudioUnit plugin handling on OS X. Anybody using Ardour 2.8.7 or earlier should upgrade to enjoy increased stability and better functionality. This is the last feature-adding release of the 2.8 series. The next release of Ardour will be version 3.0-alpha1 (unless notable regressions are discovered in 2.8.8). IMPORTANT FIXES Dramatic improvements to automation editing so that it more or less works as anyone might expect. DOWNSIDE: for this release, the display of automation data is not updated in realtime while in write/touch mode. This will be fixed in a future release. Correct very strange and erratic punch recording behaviour that would create regions on tracks that were not record enabled Fix crash when zooming canvas repeatedly Fix handling of files larger than 2GB that could cause very slow reload of existing sessions (speedup was from 9 minutes to 30 seconds) Subtle but important change that may fix issues with recording not placing material in the correct location on the timeline Correctly order signal processing after adding a send (fixes issues with placement of recorded material) Regions overlapped by 2 other regions will now no longer semi-randomly fail to be audible during playback Region exports and bounces now use region fade in and fade out curves. USEFUL FIXES Save & recall port insert latency values JACK Latency = 256 menu option now works Importing files with the "Sequence files" option now works Cleanup LV2 "external gui" extension support Clear solo state when deleting a route that is soloed Notify user that deleting a route will save the session state Ellipsize long names in the track/bus inspector Force exported AIFF files to be big-endian Anchor the crossfade start and end points so that they cannot be edited Correctly retain MIDI bindings for global transport controls Do not burn 100% of a CPU's available cycles if disconnected from JACK Put the fixed size columns (check marks) on the left side of the mixer's track and group lists for easier access to their functionality Fix strange behaviour when dragging region(s) towards time zero Rationalize track selection and range selection Make selecting a range in mouse range mode work even if there is already a time selection When splitting N-channel regions to mono regions, each new region shows up as its own region, not a child of the original Clearing an automation track of data no longer generates an error when next loading the session ("Cannot reconstitute XML history node ...") HANDY NEW FEATURES Include links in Help menu to the tutorial and reference manuals switch from ctrl-drag to alt-drag for "drag-selection-as-region" change automation track selection model slightly so that auto tracks are highlighted as expected. only show range boxes when the automation will actually get edited. clicking an automation track should show the editor-mixer for the parent track Configurable behaviour when an N channel track plays a region that has less than N channels (silence or replicate the last channel). Default is silence. OS X ONLY Significantly updated version of the GTK GUI toolkit in use, which fixes a number of issues including... Multiple monitors now supported correctly Various fixes for handling AudioUnits, particularly UAD Use Apple's ExtAudioFile API for file types not otherwise handled on OS X (MP3, AAC and others) Use libsndfile to try to get timestamp info because Apple has no API for this Do not categorize AU plugins using the "subtype" property because its meaningless. Use "type" instead which is coarser but has a clear meaning. Added a shortcut to Volumes (external disk drives) when opening a session Add option to enable/disable translation on OS X Remove automation mode selector from AU plugin view window, since it doesn't do anything useful Correctly handle AU parameter types, so that more parameters are available for automation If a plugin has a Carbon-based editor, properly close that window when deleting the plugin (e.g. when closing the session) TRANSLATION UPDATES Spanish (Pablo Fernández) French (Raphaël Doursenaud) CONTRIBUTORS Carl Hetherington, Lucus, DHess, Ben Loftis and Old Man Davis

gst123-0.1.0

by Stefan Westerfeld

gst123-0.1.0 has been released. Overview of Changes in gst123-0.1.0: ------------------------------------ * proper support for watching video files with gst123 - fullscreen mode (f) - keys (like page up, cursor left, ...) work within the video window - hide mouse in video widget - use correct aspect ratio during zoom * better option parsing (--help, --help-gst, --help-gtk work) * possibilty to disable video stream (-x, --novideo) * indicate pause / muted state (prints [PAUSED], [MUTED] in status display) * use GStreamer playbin2 What is gst123? --------------- The program gst123 is designed to be a more flexible command line player in the spirit of ogg123 and mpg123, based on gstreamer. It plays all file formats gstreamer understands, so if you have a music collection which contains different file formats, like flac, ogg and mp3, you can use gst123 to play all your music files. Since gst123-0.1.0 support for watching videos has been added; however gst123 should run fine in situations where no X11 display is available; videos can be played without X11 display, too (-x, --novideo); in this case, only the audio stream will be played. It is implemented in C++ and licensed under the GNU LGPL version 2 Links: ------ Website: http://space.twc.de/~stefan/gst123.php Download: http://space.twc.de/~stefan/gst123/gst123-0.1.0.tar.gz -- Stefan Westerfeld, Hamburg/Germany, http://space.twc.de/~stefan

xjadeo 0.4.10 is out.

by Robin Gareus

I'm please to announce that xjadeo just got bumped up to version 0.4.10: Xjadeo - X Jack Video Monitor http://xjadeo.sourceforge.net/ Xjadeo is a simple movie player that synchronizes video to an external time source such as jack-transport or Midi timecode. Download: https://sourceforge.net/projects/xjadeo/files/ Release Notes for xjadeo 0.4.10 (svn r215) ------------------------------------------ Recent Changes: - added drop-frame timecode detection by video-file framerate. Previous versions relied on MTC to report it and it was not available when synchronized to JACK or using OSC or manual sync. This change affects only the on-screen displayed timecode; internally xjadeo is computing/counting frames - not timecode. - re-implemented video start-time/start-offset parsing. - fixed some orthographic typos (man page, usage information) - updates to the build & packaging system. - various small fixes for OSX: OSD font & alignment default black-screen (no more YUV green) DMG with symlink to Applications & background-image multi-arch (PPC, i386) builds (no 64bit version) linked with JackMP (http://www.jackosx.com/) - contrib: updated time-stamp movie-maker & ran various [regression] tests. - return of the debian package (compiled for debian + debian-multimedia)

Qtractor 0.4.6 - The Funky Deviless is here!

by Rui Nuno Capela

So much to tell, even more to do... then one could hardly shake, this long overdue. Lousy rhymes and no miserly times. And there it is: a bug-fix release, I'll mean to ease. Oh crap! Let's get it through once and for all. With huge compliments to all who got the nerve and report as many too much idiosyncrasies (nee bugs). Don't, never look back. There's plenty more ahead, no matter where you look, or hear, whether is up or down hill :) Qtractor 0.4.6 (funky deviless) is here! Release highlights: - MIDI Editor draw mode (aka paint mode) (NEW) - MIDI Swing-quantize (NEW) - LV2 UI Instance & Data-access extension support (NEW) - JACK Session support (EXPERIMENTAL) (NEW) - LV2 Save/Restore extension support (NEW) - MIDI Editor event list in-line editing (NEW) - MIDI Clip time-stretching (FIX) - MIDI Clip editor file salvage quietness (NEW) - MIDI Control bus switching crash (FIX) - MIDI Bank-selection backout (FIX) - Initial widget geometry extents (FIX) - Input-only bus playback crash (FIX) - Bus connection persistence crash (FIX) - Drag-and-drop cloning plugins (FIX) - MIDI Editor floating-selection persistence (NEW) - Audio inserts garbage signal (FIX) A bit more or not so detailed change-log is found below. Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball: http://downloads.sourceforge.net/qtractor/qtractor-0.4.6.tar.gz - source package (openSUSE 11.2): http://downloads.sourceforge.net/qtractor/qtractor-0.4.6-4.rncbc.suse112.sr… - binary packages (openSUSE 11.2): http://downloads.sourceforge.net/qtractor/qtractor-0.4.6-4.rncbc.suse112.i5… http://downloads.sourceforge.net/qtractor/qtractor-0.4.6-4.rncbc.suse112.x8… - binary packages (Ubuntu 10.04): http://downloads.sourceforge.net/qtractor/qtractor_0.4.6-4.rncbc.ubuntu1004… http://downloads.sourceforge.net/qtractor/qtractor_0.4.6-4.rncbc.ubuntu1004… - user manual (outrageously outdated): http://downloads.sourceforge.net/qtractor/qtractor-0.3.0-user-manual.pdf Weblog (upstream support): http://www.rncbc.org License (no kiddin'): Qtractor is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Change-log: - Introducing a non-painting edit sub-mode on the MIDI clip editor's piano-roll (see Edit/Select Mode/Edit Draw menu). - The MIDI clip editor (aka piano-roll) is now a lot more quiet about saving its own dirty content, delegating all salvage questions to main session control. - Don't show session restart message box when changing JACK transport mode option anymore. - Dedicated MIDI control bus switching fixed. Was closing the wrong bus eventually and crashing the whole show with it (fixes bug #2989590). - MIDI bank/program backout has been corrected on MIDI track properties dialog rejection (ie. user cancellation). - MIDI bank select method has been corrected for tracks with no instrument defined (probably fixing bug #2987071). - LV2 UI Instance and Data Access extension support added; reduce LV2 external UI parameter value update flickering. - JACK session infrastructure support. (EXPERIMENTAL) - Initial widget geometry and visibility persistence logic has been slightly revised as much to avoid crash failures due to wrong main widget hidden state. - Initial mixer widget extents are now set reasonably larger. - General source tree layout and build configuration change. - Ever since smooth-ramping introduction that having at least one input-only buses were causing immediate playback crashes, now hopefully fixed. - Refactored for common engine client nomenclature, primarily provided by JACK, then secondarily passed to ALSA Sequencer, getting rid of the JackUseExactName requirement and lifting the unique/single instance restriction in the process. - Current JACK Transport, MMC Device, and MIDI Song Position pointer (SPP) control modes are now saved/loaded as part of session option properties. - MIDI clip editor's context menu crash on Qt >= 4.6 has been fixed (resolving bug #2972603). - An ancient double-free corruption has been finally fixed at the audio/MIDI bus connection persistence logic. - Improved visibility of track state buttons text (R, M, S) when turned on dark colored themes. - LV2 Save/Restore extension support kicks off. - MIDI engine read-ahead period has been shortened to half than it was since inception--now it's a 500msec cycle. - MIDI clip editor event list gets its due inline editing, for time, note, value/velocity and duration columns, just one double-click away over the target cell ;) - Add-plugin selection dialog position and extent are now remembered across invocations and application sessions (tipping by Frank Neumann). - MIDI clip time-stretching is now made available through the same gestures as audio ones, by just shift+dragging either of the clip edges. - Drag-and-copying plug-in instances (cloning) is now fixed with regard to parameter value replication. - MIDI clip editor snap-per-beat setting is now independent from main multi-track view; File/Save As... dialog fixed; the current event selection is now kept floating as long as it's possible after editing command actions; finally, edit mode has been extended to free-hand event drawing, chalking off (piano roll) draw mode from the TODO list. - Swing-quantize has finally made its overdue debut as an additional MIDI clip editor tool (see Tools/Quantize...). - Almost since its inception, audio inserts were injecting garbage random noise when not being activated, now fixed. - Dedicated audio output ports for MIDI track plugins, now have their connection persistence back in business due on session load. Cheers && Enjoy (what else?) -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

arpage 0.3.3 alpha - JACK Sync'd Arpeggiator - available on sourceforge in tarball and SVN

by Mark Vitek

Arpage alpha 0.3.3 is now available on sourceforge in tarball and SVN Main Page: https://sourceforge.net/projects/arpage/ Tarball: https://sourceforge.net/projects/arpage/files/Alpha%20Release%200.3/arpage-… SVN access: svn co https://arpage.svn.sourceforge.net/svnroot/arpage arpage ** 0.3.3 New Features: (1) The state of each arpeggiator is saved when the transport stops, or the application is shut down. This is a precursor to actually saving/restoring patches on demand, by name. These files are stored to ~/.arpage, which is created if not there. ** Fixes: (1) The initial patch number is now sent when the transport starts rolling. ** Extras: (1) Demo mp3s and session xml files available on sourceforge, as "arpage_extras-0.3.3.tar.gz" Copy the xml files to ~/.arpage to recreate the demo settings. Demos were made using WhySynth DSSI plugin w/ ghostess (a jack-dssi GUI host). ** 0.3 New Features: (1) Enhanced latching functionality: - New "Tap-out" mode - when enabled, any note in a pattern that is latched by Controller 64 ON can be removed from the latched pattern by tapping the note again. - Notes which are still held when a latched pattern is released by Controller 64 OFF will remain in the arpeggiated pattern until they are released. (2) Status "lights" for active/inactive status, MIDI output and pattern latch status (3) UI should now be small enough for netbook screens (4) Comprehensive tooltips are now provided ** Fixes: (1) Timing drift is corrected (2) Latching should be much more stable (3) Note length functionality has been corrected Enjoy! Let me know how it works for you.

spectmorph-0.0.2

by Stefan Westerfeld

spectmorph-0.0.2 has been released. This is the first publicly announce release. Overview of Changes in spectmorph-0.0.2: ---------------------------------------- * bugfixes * include proper phases, so phase-correct reconstruction of samples is possible * new programs: - smstrip - removes debugging information from SpectMorph model files - smextract - extracts data from SpectMorph models, for developers only for now * added --no-noise / --no-sines switches for smplay * added -s switch for smenc, to create stripped models * use boost numeric bindings + lapack for ideal phase/magnitude estimation (smenc -O2) - slow! * SSE optimizations and other speedups for fast phase/magnitude estimation (smenc -O1) * use odd/centered FFT to be able to reconstruct phases from FFT data (smenc -O0) * use different thresholding scheme for encoder, detecting more partials * document API with doxygen * move Encoder and other classes to libspectmorph * added python binding, capable of reading SpectMorph model files * added automated tests * added manual pages for smenc, smplay, smvisualize and smstrip * added overview document in docs directory What is SpectMorph? ------------------- SpectMorph is a free software project which allows to analyze samples of musical instruments. This should allow constructing hybrid sounds, for instance a sound between a trumpet and a flute. Also interpolating between two samples of the same instrument (different attack velocity of a piano) could be interesting. SpectMorph is implemented in C++ and licensed under the GNU LGPL version 3 SpectMorph currently is in the early stages of development, which means that it is not yet ready to be used by end users. Links: ------ Website: http://space.twc.de/~stefan/spectmorph.php Download: http://space.twc.de/~stefan/spectmorph/spectmorph-0.0.2.tar.gz There are sound examples on the website which demonstrate the sound quality of the current SpectMorph models using piano samples. -- Stefan Westerfeld, Hamburg/Germany, http://space.twc.de/~stefan
