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. The output facilities to Lilypond are greatly revised in this release. Strasheela now outputs the format of the latest stable Lilypond release (2.10.0), supports various special cases (e.g., single staff polyphony, chords, enharmonic notation, basic tuplets), and the customisation options have been extended. New examples demonstrate these features. In addition, this version facilitates composition in 22-tone equal temperament (22 ET): various 22 ET chords and scales are provided, and output to Lilypond, as well as Csound is supported. New examples have been added which create microtonal chord progressions. Other additions and bugfixes have been made to the system as well.

Rivendell v1.0.0rc0

by Fred Gleason

On behalf of the entire Rivendell development team, I'm pleased to announce the release of Rivendell v1.0.0rc0. Rivendell is a full-featured radio automation system targeted for use in professional broadcast environments. It is available under the GNU General Public License. Changes in this release include (from the NEWS file): *** snip snip *** New Switcher Device. Support has been added for the 'Quartz' line of video routing switchers made by Evertz. See the relevant section in 'docs/SWITCHERS.txt' for details. Logging Changes. A [Logs] section has been added to rd.conf(5) for configuring event logging. Logging can now be done directly to files (as before) or through the syslog facility. See the comments in 'conf/rd.conf-sample' for details on setting this up. Overlap Transition Retired. The ability to schedule 'Overlap' transitions in program logs has been removed. The equivalent functionality can still be achieved by scheduling a 'Segue' transition with the 'No Fade at Event End' attribute enabled. Any existing overlap transitions will be automatically converted when the database schema update is applied. Random Cut Rotation Retired. The ability to schedule cuts to rotate 'randomly' within a cart has been removed, with all cut rotation now using the original 'sequential' algorithm. Bugfixes. See the ChangeLog for details. Database Update: This version of Rivendell uses database schema version 158, and will automatically upgrade any earlier versions. To see the current schema version prior to upgrade, see RDAdmin->SystemInfo. As always, be sure to run RDAdmin immediately after upgrading to allow any necessary changes to the database schema to be applied. *** snip snip *** Further information, screenshots and download links are available at: http://www.rivendellaudio.org/ Cheers! |-------------------------------------------------------------------------| | Frederick F.

[ANN] jack_capture V0.9.10 and Snd-ls V0.9.8.16

by Kjetil S. Matheussen

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...) Screenshot: http://www.notam02.no/arkiv/src/jack_capture.png http://www.notam02.no/arkiv/src/?M=D 0.9.7 -> 0.9.10: *Fixed segfault in case the --channels / -c argument is higher than the number of ports which is possible to connect to. *Added a terminal vu meter by default. It'll also display red in case the recorded jack value is equal to or higher than 1.0. Use "-dv" to disable. *Added the --meterbridge / -mb option, which automatically starts Steve Harris' meterbridge (http://plugin.org.uk/meterbridge/) and constantly connects them to the same ports as jack_capture is connected to. *Added the --write-to-stdout / -ws option which writes 16 bit little endian sound to stdout. Code made by looking at jack-stdout.c by Robin Gareus. *Added the --print-formats / -pf option. *Replaced jack_client_new() with jack_client_open() Snd-ls V0.9.8.16 ================ Snd-ls is a distribution of Bill Schottstaedt's sound editor SND. (http://ccrma.stanford.edu/software/snd/) Its target is people that don't know scheme very well, and don't want to spend too much time configuring Snd. It can also serve as a quick introduction to Snd and how it can be set up. Snd-ls also serves as base code for the San-Dysth softsynth (http://www.notam02.no/~kjetism/sandysth/) and the Snd-rt music programming language (http://www.notam02.no/arkiv/doc/snd-rt) http://www.notam02.no/arkiv/src/snd/ 0.9.8.13 -> 0.9.8.16: *Fixed definstrument and faust. *Removed deprecated CAIRO_FONT_TYPE_ATSUI *Updated <slider> in snd-rt, <slider> in gui. (bugs reported by "border") *Fixed definstrument. *Replaced jack_client_new with jack_client_open

[ANNOUNCE] pytagsfs version 0.6.0

by Forest Bond

Hi, [I've sent this message to several large mailing lists. Please be sure any replies don't get sent to all of them, i.e. don't use the Reply-to-all feature of your mail client.] I'm pleased to announce the release of pytagsfs version 0.6.0. This release includes significant enhancements as well as critical bug fixes: * Support for mkdir/rmdir. * Improved performance for readdir. This makes directory listings faster. * Fix for broken stat result caching. This bug would have caused significant performance problems. * Fix for incorrect directory timestamps. * Fix for bad handling of updates to previously unrepresentable source files. This bug would cause files to not appear under the mount tree when tagged. * Fix for incompatibility with version 0.2 of the Python FUSE bindings. Thanks to Chris Pickel and Jeremy Jones for reporting bugs and testing fixes. The full set of changes for this release is available: http://www.pytagsfs.org/Changelogs/0.6.0 To download this release: http://www.pytagsfs.org/Download pytagsfs is a FUSE filesystem that arranges media files in a virtual directory structure based on the file tags. For instance, a set of audio files could be mapped to a new directory structure organizing them hierarchically by album, genre, release date, etc. File tags can be changed by moving and renaming virtual files and directories. The virtual files can also be modified directly, and, of course, can be opened and played just like regular files. For a more thorough introduction, see: http://www.pytagsfs.org/Introduction Please visit http://www.pytagsfs.org to obtain more information. Feel free to contact me with any questions. Feedback is appreciated. Thanks, Forest -- Forest Bond http://www.alittletooquiet.net http://www.pytagsfs.org

Strasheela 0.9.3 has been released

by Torsten Anders

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 adds music theoretical concepts. A generalized version of Schoenberg's guidelines on writing good tonal chord progressions have been implemented as constraints. Strasheela now facilitates composition in 31-tone equal temperament (31 ET). For example, various 31 ET chords and scales are provided, and output to Lilypond, as well as Csound is supported. 31 ET MIDI output can be defined by the user, depending on your MIDI setup. Other additions and bugfixes have been made to the system as well.
