This is the first public release of Virtual MIDI Piano Keyboard. It is a MIDI event 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. VMPK has been tested in Linux and Windows, but maybe you can build it also in Mac OSX and SGI Irix. If you can compile and test the program in those systems, please drop me a mail. The Virtual Keyboard by Takashi Iway (vkeybd) has been the inspiration for this one. It is a wonderful piece of software and has served us well for many years. Thanks! VMPK is written in C++ using two free and platform independent frameworks: Qt4 (4.3 or newer is needed) and RtMIDI for MIDI input/output. It uses ALSA sequencer in Linux, WinMM in Windows and CoreMIDI in Mac OSX, which are the native MIDI systems in each supported platform. See: http://www.music.mcgill.ca/~gary/rtmidi/ The alphanumeric keyboard mapping can be configured from inside the program using the GUI interface, and the settings are stored in XML files. Some maps for Spanish, German and French keyboard layouts are provided. VMPK can send program changes and controllers to a MIDI synth. The definitions for different standards and devices can be provided as .INS files, the same format used by Qtractor, TSE3, Cakewalk and Sonar. This software is in a very early alpha stage. Please feel free to contact me to ask questions, report bugs, and propose new features. You can use the tracking system at SourceForge project site.

Qtractor 0.2.1 (fainty diva) released!

by Rui Nuno Capela

Howdy! Vacation time is now gone and the rentrée is upon us, at least on this hemisphere side of the globe ;) Silly season, beloved August, summertime it is. And before it's too late, I'm proud to announce that a new alpha has summoned to the challenge: Qtractor 0.2.1 (fainty diva) has been released! Release highlights: - Gradient eye-candy (NEW) - DSSI multi-instance plug-in issue fixed - Clip waveform/piano-roll rendered while recording (NEW) - MIDI pitch-bend, omni-channel filtering and recording fixes - Play-head positioning in the thumb-view (NEW) - And many few more (see change-log below:) For the clueless: Qtractor is an audio/MIDI multi-track sequencer application written in C++ with the Qt4 framework [1]. Target platform is Linux, where the 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. 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 License: Qtractor is free, open-source software, distributed under the terms of the GNU General Public License (GPL) [15] version 2 or later. Features: - Multi-track audio and MIDI sequencing and recording. - Developed on pure Qt4 C++ application framework [1] (no Qt3 nor KDE dependencies). - Uses JACK [2] for audio and ALSA [3] sequencer for MIDI as multimedia infrastructures. - 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. - Built-in connection patchbay control and persistence (a-la QjackCtl [13]). - LADSPA [5], DSSI [11] and native VSTi [12] plug-ins 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 (via librubberband [9]) and seemless sample-rate 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] Download: http://downloads.sourceforge.net/qtractor/qtractor-0.2.1.tar.gz Change-log: 0.2.1 2008-08-30 The Faint Diva - Gradient eye-candy now featured for clips, tracks and mixer strips widget backgrounds, disabled on configure time (--disable-gradient). - MIDI pitch-bend/wheel events are now captured/recorded properly; in fact, there was this ancient bug, now squashed, as all MIDI clips weren't being stored at all if there weren't a single note event captured. - MIDI channel translation is finally in effect on monitored tracks, specially the ones set in omni-channel input mode. - MIDI open files dialog gets a few more file filter types now. - Playhead position is now shown, updated and can be also set on the main toolbar session thumb-view (shift-click to set the playhead). - The floating selection, as shown for a clipboard pasting operation, has been corrected regarding time scale (horizontal zoom) changes, while in the main track-view. Also fixed final position snapping precision (spotted in bug #2055846). - Current tempo and snap-per-beat setting now survive session cycling. - DSSI plugins implementing run_multiple_synths (eg. fluidsynth-dssi) are now formally supported according to the DSSI spec (hopefully); note that previously one could only have one DSSI plugin instance loaded in session in any given time, otherwise a sudden crash was in sure demand when either plugin got activated (fixes bug #2048198). - Audio plugin outputs now overrides each other when the number of output ports does not match the number of mix-down audio channels and thus fixing a nasty crash bug in the process. - All custom font sizes are now set relative to default global font. - Changing loop points by dragging on the time rulers is now mapped as undoable/redoable commands as it ought to be ever since. - Drop-span option (View/Options.../Drop multiple audio files into the same track) now takes into effect the current session snap-per-beat setting when concatenating multiple audio clips. - All plugins get their default bank/program selected on insertion. - Make record armed tracks muted for playback, a needed regression to let both audio and MIDI tracks behave consistently regarding input monitor switching through output. - Fixed a pretty old and shameless bug regarding MIDI clip recording, in which cases the queue start time offset was not taken into account, with captured events being recorded with erratic long delays. - Almost complete refactoring of the clumsy audio peak file classes, possibly making it even clumsier but straight neverthless, with the noble and final aim to build it in-flight and draw the waveforms while recording is rolling. - Recording clips get their initial name labels drawn while fade-in/out handles are dropped as found pretty useless while recording. - Escape key now closes connections and mixer widgets as found usual. 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 (still) 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. References: [1] Qt4 (core, gui, xml), C++ class library and tools for crossplatform development and internationalization http://www.trolltech.org/products/qt/ [2] JACK Audio Connection Kit http://jackaudio.org/ [3] ALSA, Advanced Linux Sound Architecture http://www.alsa-project.org/ [4] libsndfile, C library for reading and writing files containing sampled sound http://www.mega-nerd.com/libsndfile/ [5] LADSPA, Linux Audio Developer's Simple Plugin API http://www.ladspa.org/ [6] libvorbis (enc, file), Ogg Vorbis audio compression http://xiph.org/vorbis/ [7] libmad, High-quality MPEG audio decoder http://www.underbit.com/products/mad/ [8] libsamplerate, The secret rabbit code, C library for audio sample rate conversion http://www.mega-nerd.com/SRC/ [9] librubberband, Rubber Band Audio Time Stretcher, an audio time-stretching and pitch-shifting library http://breakfastquay.com/rubberband/ [10] liblo, Lightweight OSC implementation (needed for DSSI GUI support) http://liblo.sourceforge.net/ [11] DSSI, an API for soft synth plugins with custom user interfaces http://dssi.sourceforge.net/ [12] VST SDK, Steinberg's Virtual Studio Technology (see README.VST) http://www.steinberg.net/ [13] QjackCtl - JACK Qt GUI Interface http://qjackctl.sourceforge.net [14] GNU General Public License http://www.gnu.org/copyleft/gpl.html [15] Cakewalk (by Roland), powerful and easy-to-use tools for Windows-based music and sound production http://www.cakewalk.com/ Cheers && Enjoy. -- rncbc aka Rui Nuno Capela rncbc at rncbc dot org http://www.rncbc.org _______________________________________________ Linux-audio-user mailing list Linux-audio-user(a)lists.linuxaudio.org http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user

Amuc 1.7 released

by W.Boeke

Announcing Amuc version 1.7: http://members.chello.nl/w.boeke/amuc/index.html Amuc (the Amsterdam Music Composer) is an audio application for composing and playing music. With this version it is more or less loosing its innocence ... Amuc now interfaces with Jack, and text and graphics are neatly anti-alias'ed. What has remained is its speedy operation. As a little joke you can listen to this "audio greeting card": http://members.chello.nl/w.boeke/amuc/hi-woody.ogg

Strasheela 0.9.6 released

by Torsten Anders

Hello, Strasheela is a highly expressive constraint-based music composition system. Users declaratively state a music theory and the computer generates music which complies with this theory. A theory is formulated as a constraint satisfaction problem (CSP) by a set of rules (constraints) applied to a music representation in which some aspects are expressed by variables (unknowns). Music constraint programming is style-independent and is well-suited for highly complex theories (e.g. a fully-fledged theory of harmony). Results can be output into various formats including MIDI, Lilypond, and Csound. This release supports new techniques for constraining the musical form, and demonstrates them in examples. Also, the definition of complex distribution strategies (variable orderings in the search) is simplified by special constructor functions. Several further examples have been added, and many other extensions and bug fixes have been made; see the list of changes for details. For more information on Strasheela, please visit http://strasheela.sourceforge.net/ Changes are described at http://strasheela.sourceforge.net/strasheela/doc/Changes.html This release can be downloaded from: https://sourceforge.net/project/showfiles.php?group_id=167225 Best Torsten Anders -- Torsten Anders Interdisciplinary Centre for Computer Music Research University of Plymouth Office: +44-1752-586219 Private: +44-1752-558917 http://strasheela.sourceforge.net http://www.torsten-anders.de

[ANN] Ecasound 2.5.0 released

by Kai Vehmanen

Hello all, Ecasound 2.5.0 has been released! Releases notes follow: 1. Summary of changes in this release ------------------------------------- A set of new input types, including a tone generator, audio looper, selector and sequencer ("playat"), have been added. Ecasound EWF file support has gone through a major refactoring. Threshold gate functionality has been extended. The Ecasound Emacs mode has been updated with more ECI commands. The usual set of bugs have been fixed. 2. What is Ecasound? -------------------- Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console mode user-interface is included in the package. Primary platform for running Ecasound is GNU/Linux. Ecasound can also be run on many UNIX-derived systems such as FreeBSD, Mac OS X and Solaris. Limited support for Windows is available through Cygwin. Ecasound is licensed under the GPL. The Ecasound Control Interface (ECI) is licensed under the LGPL. 3. Changes since in 2.5.x series -------------------------------- v2.5.0: * Added a new audio looper object. For instance "-i:audioloop,foo.wav" will play "foo.wav" and loop it indefinitely. See http://eca.cx/examples and ecasound(1) man page for more information. * Added a new audio selector object. Specifying "-i:select,5,15.2,foo.wav" will play out 15.2sec of "foo.wav", starting at position 5sec (i.e. selects range 5.0-20.2sec). See http://eca.cx/examples and ecasound(1) man page for more information. * Added a new sequencer object that allows to play audio clips at a given position. Specifying "-i:playat,25.0,foo.wav" will play out "foo.wav" starting at position 25.0sec (i.e. the first 25.0secs will be silent and then "foo.wav" is played from the beginning). See http://eca.cx/examples and ecasound(1) man page for more information. * Ability to stack audio objects. For instance "-i audioloop,reverse,select,10,15,foo.wav" will loop a reversed 15sec segment taken from 10sec onwards from 'file.wav'. * Code for Ecasound Wave Files (EWF) has been mostly rewritten to fix longstanding bugs and design issues. This release also marks the ability to write to EWF files as a deprecated feature that will be removed in a later release. One new feature is the ability to specify parameters in terms of samples instead of seconds. * Added a simple tone generator object. For example '-i:tone,sine,440,10.3' will produce a 440Hz sine tone with duration of 10.3 seconds. This input type will be especially useful for reproducing bugs in complicated chainsetups, without the need to exchange complete session data (which usually are composed of large amounts of audio files). * Added 'reopen-count' parameter to threshold gate (-ge) operator. For instance when recording vinyl/tapes, this allows to automatically restart recording when a new track is started. When the gate is closed, no audio is passed through to the output file, but otherwise recording is kept running. Patch from Andrew Lees. * Major update to the "Ecasound Examples": http://eca.cx/examples * Updates to ecasound.el (ecasound emacs mode): new ECI commands exported. * Various bugs (in runtime functionality, documentation as well as build issues) have been fixed. Full list of changes is available at: - http://www.eca.cx/ecasound/history.php 4. Interface and configuration file changes ------------------------------------------- The interactive mode commands 'cop-add' and 'ctrl-add' now allow aternate syntax: both "-<id_string>:par1,...,parN" and "<id_string>:par1,...,parN" are now accepted. So while previously only "cop-add -efl:400" was recognized, now programs can also use the more sane looking "cop-add efl:400" variant. Output of "cs-status" (aka "status", "st") command has changed. More details are now printed about active chainsetups, while inactive setups are just listed. Previously one had to use multiple separate status commands ("cs-status", "aio-status" and "cop-status") to get a good overview of what is happening. The intent is to now print all essential information with just one command, while more detailed information is still available through the separate commands. 5. Contributors to 2.5.x series ------------------------------- Patches - Accepted code, documentation and build system changes v2.5.0: * Cyril Brulebois (1) [cyrilbrulebois] Compilation error with GCC-4.3. Reported as Debian bug #454890. * Fabian Groffen (1) [grobian] Fixed Mac OS X 10.5 build error. * Andrew Lees (1) [andrewl] Added 'reopen-count' parameter to '-ge'. Bug Hunting - Reports that led to bugfixes (items closed) v2.5.0: * Julien Claassen (2) Traced down a severe error in the development builds related to parsing and handling JACK connection parameters. Bugs in the refactored EWF code. * Rocco (2) Bugs in the new 'audioloop' object. Bug in JACK server connection management. * Duphil (1) Bug in 'cs-save/cs-save-as'. * Jan Weil (1) Bug in 'cs-status' output. * Sergei Steshenko (1) Sloppy parsing of "loop" device arguments Feature suggestions - Ideas that led to new features (items) v2.5.0: * Sergei Steshenko (1) Ability to use string tags as loop device identifiers Participants of the Last Minute Test Release Effort v2.5.0: * Brad Bowman * Julien Claassen * Dubphil * Rocco 6.

[ANN] klick 0.8.0, gtklick 0.1.0

by Dominic Sacré

Hi all, klick 0.8.0 is out, as well as the first release of its GUI frontend, gtklick. klick ===== klick is an advanced command-line based metronome for JACK. Features include tempo maps, four built-in sounds to choose from, JACK transport support, and a lot more. Changes in version 0.8.0: * There's a new "interactive mode" that allows you to change tempo, meter and volume while klick is running. This one was long overdue. * klick now speaks OSC. Currently only the most basic features can be controlled via OSC, but more will be implemented in the future. http://das.nasophon.de/klick/ gtklick ======= gtklick is a GTK metronome that uses klick as its backend. It's written in Python, and communicates with klick through OSC. gtklick is intentionally much more simple than klick, and does not support any of its more advanced features. http://das.nasophon.de/gtklick/ Cheers, Dominic
