Jalv 1.2.0

by David Robillard

Jalv 1.2.0 is out. Jalv is a simple but fully featured LV2 host for Jack. It runs LV2 plugins and exposes their ports as Jack ports, essentially making any LV2 plugin function as a Jack application. This release makes several improvements, upgrading is recommended. Download and more available at http://drobilla.net/software/jalv/ Changes: * Tune UI update rate and ring size based on JACK rate and MIDI buffer size to handle the handle the maximum message rate the plugin can send. * Support lv2:sampleRate control ports. * Tolerate loading presets with port values that aren’t xsd:decimal * Notify plugins of Jack transport changes by sending events (an atom:Blank with properties from the LV2 time extension) * Refuse to instantiate plugins which require unsupported features * Support LV2 buf-size extension (with all features) * Add Gtk3 UI * Port to MinGW * Fix Jack Session support Enjoy, -dr

LV2 1.2.0

by David Robillard

LV2 1.2.0 is out. This release adds three new extensions: * options, a generic mechanism for hosts to pass options to plugins at instantiation time (and optionally get/set them later) * buf-size, which allows hosts to provide block length and buffer size information to plugins (via options), and plugins to to require restrictions such as fixed and/or power of 2 block lengths * morph, which allows port types to be changed dynamically, with backwards compatibility (e.g. control ports can optionally be used as CV ports in hosts aware of this extension) There are also many improvements to the existing specifications. Complete list of changes: * Use stricter datatype definitions conformant with the XSD and OWL specifications for better validation. * Move all project metadata for extensions (e.g. change log) to separate files to spare hosts from loading them during discovery. * lv2core: Use consistent label style. * atom: Fix lv2_atom_object_next() on 32-bit platforms. * atom: Fix outdated documentation in forge.h. * atom: Add lv2_atom_object_body_get(). * atom: Add LV2_ATOM_CONTENTS_CONST and LV2_ATOM_BODY_CONST. * atom: Fix implicit conversions in forge.h that are invalid in C++11. * atom: Use consistent label style. * buf-size: Initial release. * dynmanifest: Use consistent label style. * event: Use consistent label style. * event: Use more precise domain and range for EventPort properties. * event: Remove asserts from event-helper.h. * event: Make event iterator gracefully handle optional ports. * midi: Add C definitions for message types and standard controllers. * midi: Remove non-standard midi:Tick message type. * midi: Add midi:binding and midi:channel predicates. * midi: Use consistent label style. * midi: Add midi:HexByte datatype for status bytes and masks. * midi: Fix definition of SystemExclusive status byte. * morph: Initial release. * options: Initial release. * parameters: Add parameters.h of URI defines for convenience. * parameters: Use consistent label style. * parameters: Add param:sampleRate. * port-groups: Use consistent label style. * port-props: Use consistent label style. * presets: Use consistent label style. * resize-port: Initial release. * state: Use consistent label style. * time: Use consistent label style. * urid: Fix typo in urid:unmap documentation. This release is backwards compatible with LV2 1.0.0, though updating is recommended. Enjoy, -dr

Laborejo 0.3 release

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/images/screenshots/latestscreenshot.png This is the release of version 0.3 Download: https://github.com/nilsgey/Laborejo/tarball/0.3 Dependencies: http://www.laborejo.org/documentation Linux Instructions: Unpack, cd into the created directoy, execute: ./laborejo-qt 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. New since version 0.2 (highlights): -Many performance and stability improvements -Improved Midi performance. Slur ends, tenuto etc. -Ardour 3 exporter -Fine control over midi velocity and note durations per note. -Translation is now possible. A partial German translation is included. -Lisalo Importer (convenient way to create new files with all jack connections set up already) -Mirror notes, reverse, shuffle, sort ascending/descending -The GUI can now open multiple files in tabs. -Open as template: Use existing save files as templates for new ones. No need for explicit template files. Every file is one. -Many new Lilypond and GUI functions such as: Auto-Piano staff from a single track (great for arpeggios), piano pedals and many more. -Convert chord-tracks to single voice tracks Most important known problems: * This is Alpha Grade Software. Don't use for long-term work. However, the produced midis and PDFs will last forever. * There is no built-in jack midi output yet. You have to export midi files. * Documentation is nearly non-existent. * Deleting selected objects may result in strange gui behaviour. Nothing a save/reload can't fix for now. Have fun, it would be nice to hear from you! Nils http://www.laborejo.org

Mixer4 1.08 and Waveplayer 1.0

by Grekim Jennings

I am excited to announce the release of Mixer4 v 1.08 and Waveplayer 1.0. Waveplayer is a lightweight (16 KB in size) console-based .wav player using ALSA. It allows you to choose start and stop playback points, and repeat playback or editing of those points. Mixer4 is a text based audio mixer and processor which has been in development for over a year. The current release includes integration of the Waveplayer so that audio playback can initiate as soon as the mixfile is built. Preview mode allows efficient processing of portions of the mix at a time. Recent work also includes 8 submixes with patchable effects, tempo and meter mapping, and more user customizations. Mixer4 packs a lot into 120 KB! The emphasis is on sound quality, stability, and simplicity. 32 and 64 bit binaries are available here.. www.acousticrefuge.com/mixer4.htm Please feel welcome to contact me for support and questions. Best wishes, Grekim grekimj at acousticrefuge dot com

Qtractor 0.5.6 - The Golf Tango release!

by Rui Nuno Capela

Hi there, Maybe some of you agree with me, that this has been the longest since last dot release and the new one with the least brand new features count being introduced. Aha no big deal I say, the uber-procrastinator is just roaring its ugly head once more, specially after a beloved summer vacation season. Whatever. Qtractor 0.5.6 (golf tango) is now released! One of the interesting dots, if not the most, is that LV2 State Files interface implementation, once in a gruesome SNAFU support status, is now officially over. For the laymen it means that any files, referenced by those LV2 plug-ins which implement the LV2 State Files interface, will get righteously bundled to an archive/zip session file (suffix or extension .qtz), all other cases remain untouched. That should add up some notches on the session portability and archival ranks and purposes. Besides, LV2 1.0.0 compliance status is now closed business. I hope. Moving on, slowly forward... Release highlights: * LV2 State Files support (NEW) * Unused files clean-up removal (NEW) * Edit/Insert empty range (NEW) * MIME Document types and icons (NEW) * Improved plug-in state resilience (FIX) * French and Japanese translations (NEW) Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball: http://downloads.sourceforge.net/qtractor/qtractor-0.5.6.tar.gz - source package (openSUSE 12.2): http://downloads.sourceforge.net/qtractor/qtractor-0.5.6-2.rncbc.suse122.sr… - binary packages (openSUSE 12.2): http://downloads.sourceforge.net/qtractor/qtractor-0.5.6-2.rncbc.suse122.i5… http://downloads.sourceforge.net/qtractor/qtractor-0.5.6-2.rncbc.suse122.x8… - quick start guide & user manual: http://downloads.sourceforge.net/qtractor/qtractor-0.5.x-user-manual.pdf 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. Change-log: - The dedicated audio outputs setting for instrument plugins was not in effect as default global option for new MIDI tracks, now fixed, hopefully (thanks to danboid aka. Daniel MacDonald persistence). - An immediate Files widget cleanup option is now made available, as to select and remove all unused file entries. - MIDI track (un)solo/mute reset clip event sequence fixing; definite regression to MIDI track's occasional muting bug while clip editing and playback is rolling. - Apologies due on this one: shift/ctrl keyboard modifiers are back in business to change MIDI events currently selected in one single step while on MIDI clip editor (aka. piano-roll). Sorry. - Japanese (ja) translation added (by Takashi Sakamoto). - General time-scale bar, beat and tempo rounding fixing. - Keyboard shortcuts configuration (Help/Shortcuts...) now checks and warns for already assigned key sequences. - The View/Snap menu is now listed as fully accessible actions, making each snap-per-beat setting assignable to a keyboard shortcut (after a feature request by danboid aka. Daniel MacDonald, thanks). - Fixed MIDI resize tool, now applying symmetric proportional changes to pitch-bend event values [-8191, +8191]. - Fixed re-loading of LV2 Presets that are newly created/saved during current session; actually delete and remove a LV2 Preset if found in the file-system (as suggested by Jiri Prochaszka aka. Anchakor, thanks again). - Preset drop-down list is now sorted, on plugin properties dialog. - After a long absence, edit(blue) cursor vertical lines are back on the MIDI clip editor views (aka. piano-roll). - LV2 1.0.0 compliance phase II: LV2 State Files support completed. - Updated to newer LV2 External UI extension support (now maintained by Filipe Coelho aka. falktx). - Brand new editing tool: empty range insertion, split/moving clips or events forward the specified edit-head/tail interval, defaults to next measure or bar (cf. menu Edit/Insert/Range, Track Range). - Don't show the waiting cursor anymore when loading any plugins which might have a nice native editor (GUI) and options are set to show it. - MIDI clip editor now hopefully rid of random but persistent muting, a slight regression to editing while playback is rolling. - A MIDI file player's bug, evident while transport rolling in looped mode, has been fixed with yet another oneliner patch (kind by Jiri Prochaszka aka. Anchakor, thanks again). - LV2 plugins with a Qt4 GUI (guess what or whom?) are now guaranteed to some reasonable window type like Qt::Widget but not Qt::Dialog nor Qt::Popup, preventing those from standing always on top while on some window managers or desktop environments (a simple addition by Jiri Prochaszka aka. Anchakor, thanks). - MIME type icons support for session (*.qtr *.qtr), template (*.qtt) and zip/archive (*.qtz) are now being introduced. - LV2 State Files feature support is shamelessly getting real trial, now letting files referenced in LV2 plugin states to be seamlessly included when saving to a zip/archive file bundle (.qtz suffix). Added some virtual destructor stubs to shut up gcc 4.7 warnings. - Improved plugin state resilience, now finally with parameter name matching, specifically targeted on loading old sessions or plugin preset files (.qtx), preserving old saved plugin states as much as possible in face of rogue or discrete parameter index renumbering, due naturally on any plugin's life cycle ie. upgrades etc.;) - Added some more snap-to-beat divisors (Beat/14, /21 and /28) due on feature request ticket, while dropping highest, probably useless one (Beat/128). - New French (fr) translation added (by Yann Collette, thanks). - Slight late optimization on vertical zebra/grid lines drawing. Enjoy! -- rncbc aka Rui Nuno Capela
