The first unified LV2 release, LV2 1.0.0, is out. This release merges the previous lv2core package with all the official extension packages, as well as example plugins, lv2specgen, and additional data. From a developer point of view, the biggest change is that all LV2 API headers can be used by simply checking for the single pkg-config package "lv2" (for compatibility the previous "lv2core" package is still installed). Implementations are encouraged to abandon the "copy paste headers" practice and depend on this package instead. With this release, several new extensions have become stable that together greatly increase the power of LV2: atom, log, parameters, patch, port-groups, port-props, resize-port, state, time, worker.

[LAA] Laborejo 0.5: Container, Collection, Parts

by Nils Gey

Laborejo, Esperanto for "Workshop", is used to craft music through notation. It is a Lilypond GUI frontend, a MIDI creator and finally a tool collection to inspire and help you compose. It works by reducing music-redundancy and by seperating layout and data. Before you read the details make sure to connect to Laborejos Facebook, Twitter or Google Plus! https://www.facebook.com/Laborejo https://twitter.com/#!/Laborejo https://plus.google.com/b/116744898976321238325/ Screenshot: http://www.laborejo.org/latestscreenshot.png and: http://laborejo.org/Screenshots This marks the release of version 0.5 Download: https://github.com/nilsgey/Laborejo/tarball/0.5 Dependencies: http://www.laborejo.org/Download Linux Instructions: Unpack, cd into the created directoy, start the GUI Editor with: ./laborejo-qt and the Collection Editor with: ./laborejo-collection-editor Then use the number- and cursor keys for immediate success! Check Help->Manual for navigational and note/rest entry keys. Everything else is in the menus. Important New Features: * Laborejo Collections: A new file format (.lbj), editable by the new GUI tool "Laborejo Collection Editor" or with a text-editor, because it is very easy. * Combine several score files (.lbjs) into a bigger one during export: Multi-movement symphonies, songbooks, collections of your band songs in one pdf etc. * Doesn't touch your actual music data but reformats for the new format and can add extra information like piece-numbering, transposition of the whole music and more. * Load a lbj file in the standard Score editor to open all used .lbjs files. * Can also combine several .lbjs scores into one, seamlessly. If you like to write long, progressive rock pieces with no breaks (in the music or pdf) you can still edit and keep them in separate pieces. Just keep the names of the tracks the same in each lbjs file. * Can use different templates (Lilypond, Ardour3 etc. layout and style files) and override the original score file template. * Part Extraction / Voice Extraction (aka. Custom Export): * Create multiple PDFs or MIDI files from one .lbjs. Does not touch your music, all automated. Simply choose a parameter as extract basis (Track, Group, Instrument, a special Extract parameter for complete individual control [recommended]) and hit "Export". * Can be combined with Collections! Combine your songs into a song collection and then export parts, one songbook/PDF for the guitarist, one songbook for the bassist. The singer and the drummer can't read notes, though. * Collapse/Shrink Tracks to save space. * Reverse Selections by 1.simply reverse order 2.reverse only pitch 3. reverse only rhythm * Non-Transparent Containers. Can contain any objects, represented by a colored "block" in the GUI. Editable in its own windows. Screenshot: http://www.laborejo.org/dl3&display * Edit any container (including transparent containers, whole tracks and substitutions) in its own tab. * Mini Lilypond Parser so you can insert notes by a script, using Lilypond syntax (just the music, no ornaments, no scheme functions) * And of course the usual GUI improvements, bug fixes and stability improvements. Greetings, Nils Gey http://www.laborejo.org
