[ANN] a2jmidid version 4 "Devsirme" released

by Nedko Arnaudov

a2jmidid is a project that aims to ease usage of legacy ALSA sequencer applications, in a JACK MIDI enabled system. a2jmidid implementation is based on jack-alsamidi-0.5 that is [almost] same as jackd ALSA "seq" MIDI backend, both created by Dmitry Baikov. Static bridges are based on code by Sean Bolton and Lars Luthman. Homepage with screenshots: http://home.gna.org/a2jmidid/ Tarball download: http://download.gna.org/a2jmidid/ Changes since version 3: * Fix typos in docs * Disable use of C++ demangling in sigsegv. Fix for sr #2074 * Fix a2j_control help text (thanks kfoltman!) * Request fixed JACK client name. Fix for bug #12139 * Handle missing svnversion executable nicely. Fixes bug #12138 Changes since version 2: * Improved port naming, support for bidirectional ports * Allow exporting of hardware ports (disabled by default) * Switch from autotools to waf * Remove support for old JACK MIDI API variants * Remove usage of posix semaphores that could cause sleep in realtime context, in rare circumstances * D-Bus background service mode. The old manual mode is still working. * Log file when running in background service mode. * Improved documentation * Import, with slight modifications, static bridges created by Sean Bolton and Lars Luthman. -- Nedko Arnaudov <GnuPG KeyID: DE1716B0>

[ANN] Realtime priority patch for the linux kernel, jack_capture V0.9.23 and Rollendurcmesserzeitsammler V0.0.4

by Kjetil S. Matheussen

Download from: http://old.notam02.no/arkiv/src/?M=D Realtime priority patch for the linux kernel ============================================ To make sure the Linux kernel is able to grant realtime priority, and full nice and mlock capabailites can still be a little bit inconvenient and/or frustrating. However, this super-tiny patch: http://old.notam02.no/arkiv/src/realtime.diff against the linux source shortcuts all other methods. No more pam, realtime-lsm, rtlimits etc. jack_capture ============ jack_capture is a program for recording soundfiles with jack. Its default operation is to capture whatever sound is going out to your speakers into a file. (But it can do a number of other operations as well...) Changes 0.9.19 -> 0.9.23: *Minor spellings *Check for out of memory *Clean up source a bit *Stop connection thread before closing jack client. *Made --help a tiny bit cleaner *Removed shut down code from the SIGINT signal handler. *Fixed segfault in case jack shuts down. Thanks to Julien Claassen for reporting the bug. (Note that there is also a 0.9.24 release. 0.9.24 has changed internal data representation from lockless ringbuffer to lockless lifo and fifo stacks. (Unmodified lifo/fifo code taken from midishare. (Copyright Grame 1999-2005)) 0.9.24 probably works fine, but it shouldn't be used for important recordings since it hasn't been much tested yet.) Rollendurchmesserzeitsammler v0.0.5 ------------------------------------ The Audio Rollendurchmesserzeitsammler is a conservative garbage collector especially made for running inside an audio DSP thread. New about this release is that I have finally replaced TLSF (http://rtportal.upv.es/rtmalloc/) with a pool-based dynamic memory allocator, which makes allocation using the rollendurchmesserzeitsammler approximately as fast as using custom memory pools. Using the rollendurchmesserzeitsammler should be a lot more convenient than memory pools though, and since memory is not freed manually, but instead is automatically freed in a separate thread, there is a slight chance that using rollendurchmesserzeitsammler instead of custom memory pools could make some DSP code run faster. In non-synthetic benchmarks, I have not been able to see any significant improvement in CPU use because of this compared to using the TLSF allocator. But for programs doing millions of allocations per second, the new memory allocator will probably perform significantly better than TLSF, if it would ever make sense doing so many and frequent allocations of course... Changes 0.0.4 -> 0.0.5 * Implemented a custom pool-based dynamic memory allocater. This new memory allocator is now set as default. To use TLSF instead, set "USE_TLSF=-DUSE_TLSF" in the Makefile before compiling. The following changes are caused by this switch: * Allocating memory is now approx 10 times faster (13 vs. 168 instructions for the allocation itself, but there are some GC overhead too) * The allocator copies used memory only (not just the whole heap). But not always! This was a lot more complicated to to with TLSF so I didn't do that. Note that for the garbage collector to still be hard realtime safe, the programs must ensure that full copies are taken now and then. (There's a change in the API for doing that) * Doing a garbage collection is much faster since the heaps are usually much smaller (because only used memory is copied) and that freeing is 10-20 times faster. * Further improvements for reducing memory overhead and make searching for used mem to be O(log n) instead of O(n) is much simpler now. (this is TODO though) * However 1: In case the code using the garbage collector will continue forever to allocate memory of different sizes, the new dynamic memory allocator could eventually run out of memory even if the program itself doesn't use very much memory. I don't think this is very likely to happen for DSP routines though, and there might even be solutions to fix this problem if it should ever come up. For now, just switching to TLSF fixes the problem. * However 2: in non-synthetic benchmarks, I have not been able to see any practical improvement in CPU use, apart from the slight improvement in CPU available for use in non-realtime threads because taking snapshots usually takes a lot less time now. But for programs doing millions of allocations per second, the new memory allocator will probably perform significantly better than TLSF, if it would ever make sense doing so many allocations of course.

Qtractor 0.2.0 (frolic demoiselle) is out!

by Rui Nuno Capela

Qtractor 0.2.0 (frolic demoiselle) is out! ------------------------------------------ Qtractor is an audio/MIDI multi-track sequencer application written in C++ with the Qt4 framework [1]. Target platform is Linux, where the a Jack Audio Connection Kit (JACK) for audio [2] and the Advanced Linux Sound Architecture (ALSA) for MIDI [3] are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio. Qtractor is free open-source software, distributed under the GNU General Public License (GPL) [15]. Author: Rui Nuno Capela <rncbc at rncbc dot org> Weblog: http://wwww.rncbc.org Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Download: http://downloads.sourceforge.net/qtractor/qtractor-0.2.0.tar.gz Executive summary: - Multi-track audio and MIDI sequencing and recording. - Developed on pure Qt4 C++ application framework [1] (no Qt3 nor KDE dependency). - Uses JACK [2] for audio and ALSA [3] sequencer for MIDI as infrastructure. - Traditional multi-track tape recorder control paradigm. - Audio file formats support: OGG (via libvorbis [6]), MP3 (via libmad [7], playback only), WAV, FLAC, AIFF and many, many more (via linsndfile [4]). - Standard MIDI files support (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 files (SDI). - 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. - Buil-in connection patchbay control and persistence (a-la QjackCtl [13]). - LADSPA [5], DSSI [11] and native VSTi [12] plug-in 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 clip time-stretching (WSOLA-like or via librubberband [9]), pitch-shifting (vib librubberband [9]) and samplerate conversion (via libsamplerate [8]). - Audio/MIDI track export (mix-down, merge). - Audio/MIDI metronome bar/beat clicks. - MIDI clip editor (piano roll). - MIDI instrument definitions (a-la Cakewalk(tm) [15]) - JACK transport sync master. - MMC control surface enabled. - Configurable keyboard shortcuts. Requirements: Mandatory: libqt4 [1], libjack [2], libasound [3], libsndfile [4], LADSPA [5]. Optional: libvorbis [6], libmad [7], libsamplerate [8], librubberband [9], liblo [10], DSSI [11], VST-SDK [12]. Disclaimer: Qtractor is still in some alpha stage of development, although already functional it surely has a plenty of lurking bugs. It also lacks some features that some might find critical in the application field. All is not lost, as the following are among the ones planned to be worked on in the times to come (not in any particular order): - Automation and MIDI controller mapping. - Session/project templates. - Puch-in/out and loop recording (takes). - Audio clip cross-fading. - Audio effect send/return aux. inserts. - Clip locking, muting, normalize (gain). - LV2 plug-in support. - JACK MIDI support. - Tempo and key signature map. - Paste-repeat command. - MIDI SysEx manager. - MIDI event list editor. - MIDI editor (piano roll) draw mode. - MIDI groove/swing quantize. - OSC interface. - Scripting. - Etc. etc. Change-log: 2009-07-18 0.2.0 The Frolic Demoiselle - MIDI clip filename revision logic is now introduced, thus avoiding the proliferation of several numbered SMF's on each edit/save; some lurking bugs were exposed in the MIDI clip externalization method but promptly squashed. - Fixed a mouse release event glitch while in drag-and-drop items in the Files tree list widget. - A dummy plugin type option has been devised, just to bear with some troubled behavior of the lovely JUCETICE plugins (View/Options.../Plugins/Experimental/Dummy VST plugin scan). Bad news are that all, yes all as in every native VST plugins, are indistinguishable from being just pure audio effects, either mono or stereo, whatever, and thus all being considered full-blown stereo VSTi instruments (which are the vast mainstream and rather interesting majority, nevertheless:). - The plugin selection dialog (Add Plugin...) now features the option whether the selected plugins should be activated on insert. - Mixer strip titles now have distinguishable type icons, either for audio or MIDI, and shown on all buses and track strips. - Major optimization breakthrough: muted audio tracks aren't streamed any longer, saving precious CPU cycles from decoding, resampling, pitch-shifting, time-stretching, plugin effects, whatever. - Incredible as it might be, audio/MIDI track record monitoring is now mixed (or merged) with rolling playback content, thus not as mutually exclusive between record and playback states anymore; also, track mute/solo states doesn't apply to recording material anymore. - Main form timer slot gets corrected and now independent of current process buffer-size in regard to JACK transport synchronization. - All file references in session state file are now stored as relative paths to main session directory. - DSSI/VSTi plugin presets can now be explicitly recalled from file (ie. Open/load preset) through this new tool button whether visible while in the generic plugin form. - Due to some trouble with newer Qt >= 4.4 applications regarding font size configuration, a new global user option is now available to the rescue: View/Options... /Display/Base font size (default is no-op). - Logarithmic scale is now taken into effect by control parameter sliders, in the generic plugin editor dialog as provided by LADSPA and DSSI plugin types. - MIDI track bank/program does not default to zero (PC#0) anymore. - Second attempt for Qt4.4 build support, regarding the bundled atomic primitives, now corrected and way more seriously :). - Long due DSSI/VSTi plugin host implementation has taken shape for MIDI instruments (eg. soft-synth plugins); DSSI reached its full host implementation and VSTi is already kicking as well (HIGHLY EXPERIMENTAL). - DSSI/VSTi plugin presets may now be stored to external XML files, which should include all parameter values and configuration data chunks, taken as proper state snapshot and subject for recall. - Dedicated audio output bus option is now also accessible for all MIDI instrument plugins, either set globally as a default mode in View/Options.../Plugins/Instruments or in the plugin context menu for MIDI tracks, as an undoable command. - Fixed a potential crash-exception due to freeing a null-pointer, raised on some ever stringent platforms and while adding tracks to empty sessions, which is the same to say this was crashing more than always:). - Loop turn-around is now taken care of, as this has been found missing and causing noticeable gapping when un-muting or changing MIDI track events while in playback. - An off-by-one bug was fixed while inside MIDI cursor backward seek method, which was missing all other events that have the same exact onset timing. - Attempt to load Qt's own translation support and get rid of the ever warning startup message, unless built in debug mode. (transaction by Guido Scholz, while on qsynth-devel, thanks). - Only one application instance is now allowed to be up and running, with immediate but graceful termination upon startup iif an already running instance is detected, which will see its main widget shown up automatically (Qt/X11 platform only). - Clip fades have now a slight transparency. - Avoid loop read-ahead on initial audio clip loading. - Messages file logging makes its first long overdue appearance, with user configurable settings in View/Options.../Logging; options dialog was slightly rearranged and moved the Plugins section into a new tab page. - Audio/MIDI drifting correction was missing its own correct and due (re)initialization whenever playback is (re)started; also, MIDI metering synchronization has been fixed once again. - Fixed session cursor backward seeking, specially applicable when playback passes the end of overlapped clips. - Fixed potential crash when opening bogus audio files. - Time-stretch FIFO buffer implementation is now made generic, as template, fixing a destructor memory leak in the process. - Include legacy headers, stdlib.h and string.h, where necessary to build with stricter gcc/g++ >= 4.3.

Ardour 2.5 released

by Paul Davis

As happens all too often, its been longer than expected between releases, but finally Ardour 2.5 is ready to ease the path, soothe the brow and excite the heart of musicians and audio engineers worldwide. Tons of bug fixes and several new features will make it worthwhile for everyone and anyone to try this out. http://ardour.org/download Note that you should probably remove ~/.ardour2/ardour.bindings in order to ensure that you get the latest key bindings. As noted below, this file will no longer be created unless you explicitly edit the key bindings yourself via the GUI. PACKAGERS and SOURCE BUILDERS please note that this release sees a new library dependency. Ardour 2.5 requires the aubio library, which is small and fast to build. Many distributions do not currently package it. You know what to do ... OS X users The first native release of 2.5 will not be ready until at the earliest July 13th, possibly as much as several days after that. We apologize for the delay, caused by problems with our build system. New Features ============= * plugin selection via menu (per plugin "manufacturer") * plugin "favorites" * dynamic track resizing with the mouse * Rhythm Ferret now has note onset detection as an alternative to percussion onsets. * make track faders display automation-driven changes * add "Consolidate Range" which writes a new audio file and uses it to replace whatever was in the playlist within the range * add "make range to next marker" and "export range" context menu items for range markers * all GUI menu items/actions can now be activated using OSC * new "name-new-markers-at-creation" option * zoom-to-region (on one or both axes) * fit-tracks (selected tracks sized to vertically fill editor window) * insert-time operation to add "silence" to the timeline * 12 saved "view states" that save zoom levels and timeline positions * working latency compensation and I/O configuration for AU plugins * goto-wall-clock command * * Fixes and Improvements ====================== * at least 20 crashing bugs fixed * use latest version of libsigc++ (potential bug fixes) * use version 1.2 of RubberBand for speed & quality improvements and potential patent avoidance * online (and available) manual updated, including correct key binding tables * editor GUI is now 100% 64-bit for audio timeline values * never save keybindings to user's ardour directory unless they change them * allow keybindings to use arrow keys (GTK doesn't permit this) * fix for plugins-do-not-work-on-all-channels bug * fix track selection sensitivity botch for Import action, should have been toggle-waveform-visible instead * Support FFT for multi channel tracks and fix analysis for tape track regions. * fix mix group problems caused by recursive loop when modifying gain/gui * make big clock stay on top even in broken desktop environments * fixes to correct the results of running time/pitch shifting multiple times on the same region * updated swedish translation * don't double-call JackStartFreewheeling if we're already freewheeling * small changes to export code to hopefully fix some bugs with range export(s) * minor UI fixes for clocks and Locations dialog. Prevent tape tracks from skewing the session extents * major fix for computing plugin I/O configuration when using mono/stereo plugins in stereo/mono tracks/busses * fix up scaling problems with cleanup caused by redisplaying all regions every time a file is removed * fix for illegal audio device selection in audio setup dialog * fix for plugins being shown twice in the automation menus * make generation of new region names scale properly rather than being O(N^2) * reset meter peaks when meter point is reset * editor faders now insensitive to unmodified scroll wheel events (Alt-scroll does the same thing) * change the step size for scroll-driven resizing * make region context menu items always operate on well-defined and reasonably obvious region selection * ctrl-w shortcut ("close dialog") works on plugin editors * make bounce range and bounce region work properly (wrong boundaries before) * prevent periodic auto-save from causing GUI deadlock during export-ranges * improve horizontal scrolling. When the playhead is moved past the end marker, the canvas will alter its boundaries as needed. The Zoom to Session button will now reset the canvas size to start-2-end plus a little extra after end, so the end marker is visible. * Move the Enable Track Meters option to Metering menu section * removing sends now cleans up fully, preventing problems when adding sends again later * check both whole-file and part-file regions when adding to the visible region list, and do not show regions that are region list equivalent with existing entries * Fix up checks for whether the track height is too small for the name highlight. Fixes irritating issue with 31 pixel height tracks having small waveforms but no name highlight. * make "feature lines" always be the right height as tracks resize * nudge clock now has a default value of 5 seconds, not zero * What used to be the pink recording rectangle is now blended into the recording regions so that they appear to be the same thing. Then recording specific colors are added so the waveform and region base when recording are all various shades of red during recording. *** Open Theme Manager and click Restore Defaults for these changes to apply *** Contributors ============ Paul Davis, Ben Loftis, Doug Mclain, Ryan Scott, Colin Fletcher, Sampo Savolainen, Jesse Chappell, Sakari Bergen, Dominic Sacre

Qsynth 0.3.3 Knobs Galore!

by Rui Nuno Capela

Greetings, Thanks to Pedro Lopez-Cabanillas and Guido Scholz, this Qsynth release is now a reality. Main new features are a the new rotating knob style options, first full translations, German and Spanish and last but not least, there's this Windows(TM) all-in-one package available (includes FluidSynth port) for your (sick:) pleasure only. Please read below the brilliant notes from Pedro about this breakthrouth release. Yes, before's too late: Qsynth</a> 0.3.3 (unstable-qt4) is out! For the clueless, Qsynth is a Qt GUI frontend application to the excellent FluidSynth (http://www.fluidsynth.org) soft-synth library implementation for the SoundFont 2 specifications. Available from the usual place: http://qsynth.sourceforge.net http://sourceforge.net/projects/qsynth There's the change log for this point release: - Due to some trouble with newer Qt >= 4.4 applications regarding font size configuration, a new global user option is now available to the rescue: Options.../Other/Base font size (default is no-op). - Knobs: graphic styles are now QStyle derived classes, which are assigned to the knobs using QWidget::setStyle(). Three styles are implemented in this way, supporting also the legacy QDial: * Our former look, tweaked and ported from Sonic Visualizer. * A port of the new look implemented by David Garcia. * Another ported widget style, designed by Giuseppe Cigala. - Spanish translation added. - Attempt to load Qt's own translation support and get rid of the ever warning startup message, unless built in debug moderr; also introducing the very first and complete German translation (patching transaction by Guido Scholz, thanks). - Messages file logging makes its first long overdue appearance, with user configurable settings in Options/Logging. - Only one application instance is now allowed to be up and running, with immediate but graceful termination upon startup iif an already running instance is detected, which will see its main widget shown up and all engines started automatically (Qt/X11 platform only).</li> Notes about the Windows(TM) package: (http://downloads.sourceforge.net/qsynth/qsynth-0.3.3-setup.exe) * It is a bundle of Fluidsynth 1.0.8 (patched) and QSynth 0.3.3, compiled in Windows with MinGW 3.4.2 and Qt 4.4.0. The package includes all the required libraries except DirectX-9, which should be installed before. The setup program itself was created with NSIS 2.37 (http://nsis.sf.net) * The patch for Fluidsynth (attached) was needed to allow QSynth to specify the name of a MIDI port to be opened other than the first one. The patch was sent to the Fluid-dev mailing list, but maybe we could offer it also in the QSynth web site? Link to the mailing list message: http://www.mail-archive.com/fluid-dev@nongnu.org/msg00816.html * Users should not expect the same functionality level in Windows compared to the Linux version. In windows it is not possible to connect the MIDI out from one program to the MIDI input of another application. QSynth/Fluidsynth needs to read MIDI events from a real MIDI device, as a keyboard. For something similar to the ALSA sequencer routing capabilities, you can try MIDIOX/MIDIYoke (http://midiox.com) Cheers && Enjoy -- rncbc aka Rui Nuno Capela
