[LAA] [ANN] Virtual MIDI Piano Keyboard 0.4.0 released

by Pedro Lopez-Cabanillas

Virtual MIDI Piano Keyboard is a MIDI events generator and receiver. It doesn't produce any sound by itself, but can be used to drive a MIDI synthesizer (either hardware or software, internal or external). You can use the computer's keyboard to play MIDI notes, and also the mouse. You can use the Virtual MIDI Piano Keyboard to display the played MIDI notes from another instrument or MIDI file player. Changes * Touch screen support (multi-touch) if it is supported by the OS and hardware. * RtMIDI-1.0.14 with Jack MIDI support. * New network MIDI driver (UDP multicast) compatible with IpMIDI and QmidiNet. * New platform: Symbian^3 port. * New translations: Dutch by Wouter Reckman, and Swedish by Magnus Johansson. * Fixed a crash when changing the octave base while channel is 10. Thanks to Mike Cookson for the report. * New build options: * RTMIDI_DRIVER: selects the RtMIDI backend. Default depends on the OS. Allowed values: ALSA, JACK, COREMIDI, IRIX, WINMM, NET. * PROGRAM_NAME: selects the executable name. Minimum requirements for all platforms: CMake 2.8 and Qt 4.6 Please use the mailing list <vmpk-devel(a)lists.sourceforge.net> for questions and comments. Thanks.

[LAA] NASPRO 0.2.91 released

by Stefano D'Angelo

Hi all, I'm glad to announce the release of NASPRO 0.2.91. NASPRO (http://naspro.atheme.org/) is meant to be a cross-platform sound processing software architecture built around the LV2 plugin standard (http://lv2plug.in/). The goal of the project is to develop a series of tools to make it easy and convenient to use LV2 for sound processing on any (relevant) platform and for everybody: end users, host developers, plugin developers, distributors and scientists/researchers. This is mostly a bugfix release with a "not officialy supported" port to Win32/64 and bunch of LV2 data-only bundles containing handcrafted the equivalent of all LRDF data I could find. It includes: NASPRO core: the portable runtime library at the bottom of the architecture; NASPRO Bridge it: a little helper library to develop insert-your-API-here to LV2 bridges; NASPRO bridges: a collection of bridges to LV2 which, once installed, allow you to use plugins developed for other plugin standards in LV2 hosts. In particular, the NASPRO bridges collection includes two bridges: a LADSPA (http://www.ladspa.org/) 1.1 and a DSSI (http://dssi.sourceforge.net/) 1.0.0/1.1.0 bridge. All of the code is released under the LGPL 2.1 license. Due to a couple of issues with Lilv (http://drobilla.net/software/lilv/) 0.4.2 and zynjacku (http://home.gna.org/zynjacku/) 6, the installation of such bundles has to be explictly requested at ./configure time. Furthermore, patches to fix a tiny bug preventing Lilv 0.4.2 from properly working with dynamic manifests and to try to fix (i.e., perhaps more a hack than a fix) cross-referencing among bundles w.r.t. dynamic manifests in zynjacku 6 are avialable in the Downloads page. More information is available on the project's website. Enjoy!

[LAA] QMidiArp 0.4.0 released

by Frank Kober

Hello all, Work is underway, mainly stimulated and supported by Nedko Arnaudov, to make this animal handle JACK MIDI natively. It is far from being finished, so it is not time for this today, but since January, some other handy features have sneaked in making it worth to give an update. Playhead cursors, waveform-recording MIDI LFOs, some new MIDI controllables and a finer step sequencer control by the keyboard are the main new features coming with QMidiArp 0.4.0. Enjoy! ---------------------------------- qmidiarp-0.4.0 (2011-05-28) New Features o All modules now have a playhead cursor o LFOs can record controller data by a MIDI-learnable Record button. o Seq modules handle note events at the input for triggering o Spanish translation thanks to Pedro Lopez-Cabanillas (plcl) o Czech translation thanks to Pavel Fric o Functional doxygen documentation available by "make doxygen-doc" o New SVG icon and desktop file QMidiArp is available for download at http://sourceforge.net/projects/qmidiarp/files/qmidiarp/0.4.0/qmidiarp-0.4.… Project page http://qmidiarp.sourceforge.net/ Git repo (developers welcome) git://qmidiarp.git.sourceforge.net/gitroot/qmidiarp/qmidiarp

[LAA] [ANN] JACK 0.120.2 + D-Bus

by Nedko Arnaudov

Tarball containing D-Bus patched jack 0.120.2 is available here: http://nedko.arnaudov.name/soft/jack/dbus/ http://nedko.arnaudov.name/soft/jack/dbus/jack-audio-connection-kit-dbus-0.… http://nedko.arnaudov.name/soft/jack/dbus/jack-audio-connection-kit-dbus-0.… A patch against vanilla 0.120.2 is available here: http://nedko.arnaudov.name/soft/jack/dbus/jack-audio-connection-kit-0.120.2… After applying the patch you have to run autoreconf. D-Bus modifications add optional autodetected support for the D-Bus based server control system. D-Bus is object model that provides IPC mechanism. D-Bus supports autoactivation of objects, thus making it simple and reliable to code a "single instance" application or daemon, and to launch applications and daemons on demand when their services are needed. * Simplified single thread model for control and monitor applications. Various D-Bus language bindings make it trivial to write control and monitor applications using scripting languages like Python, Ruby, Perl, etc.. * JACK has log file (~/.log/jack/jackdbus.log) that is available for inspection even when autoactivation happens because of first JACK application is launched. * There is real configuration file used to persist settings that can be manipulated through configuration interface of JACK D-Bus object. * Improved graph inspection and control mechanism. JACK graph is versioned. Connections, ports and clients have unique (monotonically increasing) numeric IDs. * High level abstraction of JACK settings. Allows applications that can configure JACK to expose parameters that were not known at compile (or tarball release) time. Currently there are some minor differences between jack1 jackdbus and jack2 jackdbus: * There is no parameter constraints support (no enums and no ranges) * Settings file (in ~/.config/jack/) is conf-jack1.xml instead of conf.xml, because jack1 and jack2 settings and not really compatible. When configured with D-Bus support, jack_control is installed. jack_control is simple commandline interface for jackdbus. Other tools that can communicate with JACK through D-Bus: * LADItools (tray icon, configuration, etc.) * Patchage (and lpatchage too) * LASH 0.6.x * ladish * QJackCtl -- Nedko Arnaudov <GnuPG KeyID: 5D1B58ED>

[LAA] JACK 0.120.2 released

by Paul Davis

Jack 0.120.2 is now available. http://jackaudio.org/downloads/jack-audio-connection-kit-0.120.2.tar.gz This is primarily a bug fix release, though some of the bugs are important. Fixes/Changes * Fix issues with stack initialization in client threads that stole large chunks of the stack from applications. * if the ALSA backend finds that a device is busy, try to tell the user what application(s) are using it. * Reimplement the jack_cycle_wait/jack_cycle_signal() API for OS X, where in previous versions it was completely non-functional. * extended documentation for the transport API data structures. * extended documentation for the JACK Session API * more useful warning message when duplicate port registration is attempted * fix logic for setting up device parameters in the ALSA backend (fixes JACK startup on some ALSA-supported devices that would report "impossible sample width (1) discovered" during startup).

[LAA] Several LV2 extensions

by David Robillard

>From the Dept. of Hasty Out of Order Releases: New releases of several LV2 extensions are out, updating packaging to the new LV2 4.0 style. LV2 extensions define extended functionality for LV2 plugins and are primarily of interest to developers. In particular, this provides the packages required for building the recently released Suil and Lilv (oops!), and any other code that uses the new URI-like #include style for LV2 extension headers. The extensions are: http://lv2plug.in/ns/ext/data-access http://lv2plug.in/ns/ext/event http://lv2plug.in/ns/ext/instance-access http://lv2plug.in/ns/ext/midi http://lv2plug.in/ns/ext/uri-map Documentation, links to release tarballs, and other resources can be found at the URIs above.

[LAA] Qtractor 0.4.9 - The Final Dudette is out!

by Rui Nuno Capela

Yess :) This is one hopeful attempt to be the very last one before officially entering the TYOQA age. Mainly a big fix and optimization release. Yes, you've read that right. Big. Some earthquake-bound changes have sneaked in and all under the hood. Most are bearable visible, if at all. Quite frankly, the most time-critical code paths have been subject to some kind of a deep overhaul, and to say the very least, might get only noticeable while loading hugely complex sessions. Whatever that means. In other words and put simply, there are gentle performance wins and nice resource savings. Anyway, there's no breakage regarding the past. Everything should work smooth as ever. Nevertheless, there's a good chance it might enter beta phase or whatever you wish to call it. I guess most people had ditched any serious assessment on this piece of software just because I've been sticking with an infamous alpha label for so long. Well, inb my own opinion (what else?), if you care, it's just that. All software is always either in that so-called alpha or omega-there's no middle term, all else is marketing gibberish--all software is more or less in a broken state (ie. alpha) or just simply dead and gone (omega). There you have it :) With nothing else to say (and then time being the worst of enemies), Qtractor 0.4.9 (final dudette) is out! Release highlights: * MIDI scale-quantize and snap-to-scale tools (NEW) * Audio recording latency compensation (NEW) * Mute/un-solo tracks shading (NEW) * MIDI controller invert value and connects access (NEW) * Tempo map dialog tap helper (NEW) * Audio peak/waveform generation pipeline (NEW) * Track-view clip invert selection (NEW) * MIDI clip editor range selection (NEW) * Major audio clip buffering/streaming thread optimization (FIX) * Temporary JACK session extract directory (FIX) * Red shade recording display (NEW) and looping (FIX) * Audio clip over-extended ghost-playback (FIX) * MIDI tempo map resolution import (FIX) * Audio/MIDI time drift correction (FIX) * Changed bus connections preservation (FIX) * Simultaneous multi-track recording result extents (FIX) * Track-view selection and redrawing optimization (FIX) * LV2 instrument/synth on audio tracks crash (FIX) Real juice follows, below...

Change-log: - Session file format saved on JACK session has been reverted to archive/zip bundle one (.qtz) now using temporary extraction directory when loading an existing JACK session. - Main toolbar time and tempo widgets get their visual extents a bit more theme-friendlier ;). - Some current working directory trickery is now in place avoiding JACK session directories to ever be picked as default, as much as possible. - Ghost-playbacks are now avoided on audio clips that are artificially extended beyond their own audio file lengths. - Recording clips now shown in a reddish shade; also, it's all now shown a bit more correctly, regarding the lead and withing looping range. - Custom tempo spin-box widgets now honoring the decimal point cursor positioning for integral up/down tempo value stepping. - Audio recording latency is now compensated via automatic clip offsetting. - Audio peak file generation is now pipelined on a single unique thread, instead of old one per audio clip file basis. - MIDI tempo/time-signature map import problem has been hopefully fixed (bug #329791). - Session and track names are now sanitized from slashes (bug# 625798(a)bugs.debian.org). - Mouse wheel effect to sliders is now reversed. - An appropriate export filename is now suggested as default (Track/export Tracks...). - Follow-playhead automatism is now temporarily suspended while mouse cursor hovering prompts for any editing action (applies to main track-view and MIDI clip editor/piano-roll). - Audio vs. MIDI time drift correction now takes jack_frame_time() as audio time reference. - Audio buffering internal synchronization logic gets it bartered: three bools for a single byte flag. - Connections are now preserved as possible when changing bus properties (View/Buses.../Update). - A rare audio clip looping out-of-sync condition got squared, hopefully the last ;) - Yet again, the audio clip buffer/disk-streaming optimization has been almost completely redrawn: now there's one thread per audio track. - Not replacing a session directory that already exists on loading an archive file (.qtz) is now fixed with an usable brand new untitled session. - The major thread optimization has been slightly improved: the audio clip buffer/disk-streaming thread is now served in a FIFO manner (was LIFO). - Custom time/tempo spin-box widget change fixup. - Audio clip filename change segfault/crash fixed. - Make sure all clips in multiple recording tracks start and end at the very same position whenever recording is already engaged and rolling. - Hopeful fix to a potential audio buffering race condition, which was a probable cause of random muted clips (maybe fixing bug #3290178). - Avoid recursive observer widget value updates. - Almost complete rewrite of the main track-view selection and redrawing logic, taking advantage of the fundamentally static graphical backstore. - Autonomic resizing of mixer bus splitter sizes. - Improved timing for monitored MIDI events being buffered though MIDI instrument plugins, while playback/transport is rolling. - Audio peak/waveform is now slightly tweaked from the early optimization days (master C++ guru has always said that was root of all evil anyway :). - MIDI controller mapping now with "Invert" value option. Also, new "Inputs" and "Outputs" buttons have been added as helpers for MIDI control port connections access. - Main left pane vertical splitter resize hack, avoiding some track list update re-entrancy. - Inserting a LV2 instrument/synth plugin on an audio track or bus were causing immediate crash, now fixed (give or take some event buffer stub). - Plugin Activate All/Deactivate All menu fixing. - Make sure given session directory has all the necessary access permission (read/write) while on session properties dialog. - Dedicated audio outputs setting for instrument plugins inserted on the MIDI track properties dialog were not being honored, now fixed. - Force update/close of all MIDI clips and their respective editors (piano-roll) if open, when changing the global session tempo (BPM). - Removed the misleading "(Any)" special channel value while on MIDI controllers/learn dialog. - Floating tool-tips now being shown also while on mouse rubber-banding (drag-select). - Audio clip pitch-shifting change fixing; also, tooltips now showing semitones units instead of a clueless percentage. - Rendering audio wave-forms while recording is now a little bit smoother than before. - New main track-view clip selection tool: invert current selection (Edit/Select/Invert). The MIDI clip editor (piano-roll) also gets proper range selection tool (Edit/Select/Range). - More eye-candy: muted/non-soloed tracks are now slightly shaded on the main track-view. - A major hidden optimization has been implanted: all audio clip buffer/disk-streaming threads are finally merged into a single multiplexing thread (was one thread per audio clip longer than 3 sec. which was quite wasteful and creepy;). - All plugin list view changes are now properly signaled to track properties and bus manager dialogs and enable their respective acceptance. - Two brand new MIDI tools make their appearance: Scale-Quantize and Snap-to-Scale. The later may be readily accessible from the MIDI clip editor toolbar and menu (check View/Toolbars/Scale and View/Scale). - Mixer track strips are now completely redone whenever a track gets moved or re-ordered on main track list-view. - Transport auto-backward option is now honored whenever a new session gets loaded. - LV2 extension headers update. - Got rid of recent QX11EmbedContainer bloating, while introducing gtk_init() as for LV2 GTK UI support stabilization. - Tempo tap helper button was added to View/Tempo Map... dialog. - Executable DSSI plug-in GUI detection fixed. - Backout default session directory after cleaning up extracted archive/zip bundle session (.qtz). - Files widget item selection feedback/focus fix. - MIDI editor anchor event floating tool-tip fix. - Probable fix for GtkStyle usage detection (might be gentoo specific). Cheers && Enjoy (with lots of fun!) -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org
