Hiho, I am pleased to announce the release of version 0.2 of MotionTrackOSC. MotionTrackOSC is a small program that does motiontracking on either a camera image or a video file. The tracked motion is output to a client via osc. The program is based on the libraries OpenCV - http://opencv.willowgarage.com liblo - http://liblo.sourceforge.net MotionTrackOSC is distributed with some SuperCollider classes and help files, so you can start and use the program from and with that program.

Qtractor 0.4.0 (foxy dryad) released!

by Rui Nuno Capela

Howdy! It's been quite a while since last time (Fluffy Doll on Xmas:). However, Qtractor is back again on track and this time with great news. And the big news are that this pet is leaving its rusty four-on-the-floor cage and spreading it's musical genre targets. Still a bedroom/home-studio sequencer though, but not for the techno-boy/girl only anymore--if one may trump about it, it's getting a general-purpose sticker now. And what makes it like just that? One long due feature, now stroked by implementation lightning: Tempo/Time-signature Map. Or in other words: project sessions may now have multiple parts with different tempo (BPM) and/or time-signatures. Tempo/time-signature map is/was a very pervasive feature change. Although deeply internal, as it's only evidently visible from the new View/Tempo Map... interactive yet primitive dialog, it is also accessible by double-clicking on the time rulers (main track-view and MIDI clip editors) and by left-clicking over the main tempo spin-box, which also introduces the time-signature figures as seen from the current play-head position. One should probably say that this is the major change in Qtractor internals since its primordial inception. No doubt, we're still in /alpha/ status. It surely will take a (another) while, a year or so, for a similar payload take a lift, ever again. No sweat. Watch for next favorite feature requests, like MIDI controller map/learn/feedback and automation. Coming next, soon, hopefully :) A few words of caution must be said now. It is of paramount interest for all of you who already use Qtractor for any (small) project or prototype, to be prepared for less amenable surprises. Being optimistically wise, there's a very good chance that all new workings will bring a better experience overall. But given the whole nature and depth of what got through, it is wise enough to have your backups at hand and up to date. Don't hesitate asking for help, in any case. Caveat emptor! So, with no further ado, there it is: Qtractor 0.4.0 (foxy dryad) is now released! Good old intro/description: Qtractor is an audio/MIDI multi-track sequencer application, written in C++ on top of Qt Software's Qt4 framework, having JACK and ALSA as its main infrastructures and Linux as native and exclusive platform. Specially suited to the lone-wolf composer, arranger and (re)creative music-maker personal home-studio, it still hopes to evolve as a fairly featured desktop audio/MIDI workstation or at least, a prototypical part of it ;) Release highlights: * Tempo-map/Time-signature support. (NEW) * MIDI Song Position cueueing support. (NEW) * MIDI Clip Quantize command. (NEW) * Zoom direction mode option (NEW) * MP3 audio format support (FIXED) * and many other assorted fixes and brand new bugs ;) Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball http://downloads.sourceforge.net/qtractor/qtractor-0.4.0.tar.gz - user manual http://downloads.sourceforge.net/qtractor/qtractor-0.3.0-user-manual.pdf (nb. yes, it's the same old, dusty and outdated manual, sorry) Weblog (upstream support): http://www.rncbc.org License: Qtractor is free, open-source software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. Features: - Multi-track audio and MIDI sequencing and recording. - Developed on pure Qt4 C++ application framework (no Qt3 nor KDE dependencies). - Uses JACK for audio and ALSA sequencer for MIDI as multimedia infrastructures. - Traditional multi-track tape recorder control paradigm. - Audio file formats support: OGG (via libvorbis), MP3 (via libmad, playback only), WAV, FLAC, AIFF and many, many more (via linsndfile). - Standard MIDI files support (SMF 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 file. - 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). - LADSPA, DSSI and native VST 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/MIDI clip gain/volume, normalize and export. - Audio clip time-stretching (WSOLA-like or via librubberband), pitch-shifting (also via librubberband) and seamless sample-rate conversion (via libsamplerate). - Audio/MIDI track export (mix-down, merge). - Audio/MIDI metronome bar/beat clicks. - Unlimited tempo/time-signature map. - MIDI clip editor (matrix/piano roll). - MIDI instrument definitions (a-la Cakewalk(tm)) - JACK transport sync master. - MMC control surface enabled. - MIDI Song Position cueuing support. - Configurable keyboard shortcuts. Change-log: - MIDI (re)connections fix; now caring for the ALSA client and port textual names only, avoiding as much as possible, any reliance on those volatile client and port numbers. - Transport/Backward and Forward commands may now reset to immediate full start or end of session locations, by just pressing the Shift or Ctrl keyboard modifiers and clicking their respective toolbar buttons. - Default session/MIDI resolution has been set to 960 ticks per beat (960 TPQN, where a beat equals a quarter-note); it is worth of note that the previous default resolution was set to one order of maginute lower, ie. 96 TPQN ;). - Making (dis)connections now also flags session as dirty. - Internal Audio/MIDI engines queue/time drift correction takes a brand new approach, specially adapted to rolling tempo/time-siganture changes. - MIDI monitor refresh-cycle slight internal optimization. - Converted obsolete QMessageBox forms to standard buttons. - Transport/Rewind and Fast-forward commands may now be set to double-speed, by pressing the Shift or Ctrl modifiers while clicking their respective tool buttons. - MIDI clip editor zoom ratios are now saved and preserved across sessions. - Time-signature is now directly accessible from the main tempo spin-box which also reflects current tempo status. - Time/frame spin-boxes now allow to step change each field individually, depending on the cursor beam position. - Make sure that Transport/Follow playhead option is only effective when playback is actually rolling. - Primordial attempt to include MIDI Song Position Pointer (SPP), Song Start, Stop and Continue sequencing support. - A completely new time-scale infrastructure is now in place, with full support for session tempo and time-signature map; this long due feature is primarily accessible through the main menu, View/Tempo Map...; also by double-clicking on the the main window and MIDI clip editor time rulers and left-clicking on the main toolbar tempo/signature spin-box. - Moving and resizing individual clips now cares for track proper ordering and overlapping changes, avoiding nasty out of sequence clips and other unpredictable effects. - An expedite MIDI clip quantize command is now available from the main track view menu (Edit/Clip/Quantize), which simply applies the current snap-to-beat setting to a MIDI clip range selection. - Fixed that hideous bug affecting overlapped audio clips when playhead gets moved backward, causing the playback of those audio clips in particular, go out of sync. - Tracks are now limited to their minimum height, specially effective in face of vertical zooming. - Zoom mode option introduced (on menu View/Zoom/Horizontal, Vertical, All). - Tempo beat type is a new session property; however it is not yet user modifiable and currently disabled to default MIDI quarter note (1/4). - All open MIDI clip editor time-scales are now updated and corrected when the main session time base changes (tempo, time-signature, resolution, etc.) - MIDI metronome fixed, preventing duplicate click events. - MP3 audio file decoding was broken for way too long and falling short for every file with custom frames, ID3 tags and comments. Got shamefully fixed. - Time signature denominator (ie. beat divisor) is now an accessible and effective session property. - Attempt to retain original size (clip length) of all audio clips when changing the global session tempo and automatic time-stretching is not an option. Cheers && Enjoy! -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

Hi all, (And apologies for cross posting) I'm pleased to announce QuteCsound version 0.4. This version incorporates new features and bug fixes arising from the 3 previous Release Candidate releases. QuteCsound is a simple frontend for Csound featuring a highlighting editor with autocomplete, interactive widgets and integrated help. It is a cross-platform drop in replacement for MacCsound (it can open files created in MacCsound), and aims to be a simple yet powerful and complete development environment for Csound. QuteCsound 0.4 has been tested on Windows, OS X, Linux and Solaris, and it is free software released under the GPL. You can get it here: http://sourceforge.net/project/showfiles.php?group_id=227265&package_id=275… There's more information here: http://qutecsound.sourceforge.net/ Questions, comments and suggestions can be posted to the main Csound mailing list, or join the QuteCsound users mailing list at: http://lists.sourceforge.net/lists/listinfo/qutecsound-users Thanks very much to all the people (particularly Joachim Heintz), who have provided great feedback and ideas to improve QuteCsound. Also a big thanks to Andy Fillebrown for the fixes for Windows and for preparing the Windows installers. Enjoy! Andrés Changes from version 0.4RC2: New: - Added "_Browse" channel for value buttons, which open a browse file dialog and send the selected file name to any widget with the same channel which can receive strings, like LineEdit. Added this feature to the reserved channels example. - New tutorials and example files, with clearer names. The examples can now be run directly WITHOUT saving, which is very handy especially for testing audio IO. - Console text font color can now be changed - Added a close tab button on the right corner of the tabs panel. - Modified execute code for Windows (for external utilities and terminal) - Added option to enable/disable line wrap - Added clear option to console context menus - MacCsound output filename is now parsed and added to the options - Added new FM and additive examples Fixed: - Improved stability - Files with extensions different to csd, orc and sco can now be opened - External programs and terminal are now launched correctly on all platforms - Fixed storing changes in widget panel when tab changes - Graph widget now displays graphs generated by ftgen - Widget values are now properly sent for the first control period - Files now open properly on OS X when double clicked from the Finder - Fixed problem when buffering messages - Fixed problems with filenames with spaces when rendering or opening in external programs - MacCsound sections are only created if save Widgets preference is set - New default file more consistent with current state. - Files are now not marked as modified when changing tabs - Fixed path of Manual for newer versions - Fixed resizing and moving widget edit frames when changed from the properties dialog

Strasheela 0.9.9 released

by Torsten Anders

Dear all, 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 brings many small-scale improvements and extensions to Strasheela. Most importantly, the implementation of Schoenberg's Theory of Harmony as CSP has been documented (HTML with sound examples), Strasheela now supports adaptive just intonation, the music representation has be extended by several convenient constructors, and a number of pattern constraints have been added. Also, some bug fixes have been made. 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 -- 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

First version of jackpanel (0.0.1) released

by Hans Baier

The first roughly usable version 0.0.1 of jackpanel (http://www.hans-baier.de/wordpress/jackpanel) is available. jackpanel is a graphical frontend for the JACK audio server, emphasizing simplicity, good look and feel and GNOME integration. Realtime switch, latency and samplerate can be changed with one or two mouse clicks. It comes in two flavors: A GNOME panel applet and standalone. X-runs are displayed and can be reset with a mouse click. Before starting up, make sure you have a valid .jackdrc (eg. generated using qjackctl). It will be imported on first startup. Would be nice to hear some feedback, be sure to file issues to the tracker mentioned on the project homepage. Kind regards, Hans P.S.: Jackpanel currently is not goot at configuring, but running jack. You might use qjackctl for a first time setup. After that you can use gconf-editor to manually change settings. I wrote it primarily to have JACK run when GNOME starts and to monitor its status as well as change the most important settings with one or two mouse clicks. JACK server configuration will be added later.
