Merry season greetings! After a very long quarantine period, and while after the last Flirty Ditz romance, this pet has calmly bumped a few more steps ahead. Please welcome, my Christmas present to y'all, Qtractor 0.3.0 (fluffy doll) has been released! Same old intro follows: 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: * Paste-Repeat command. (NEW) * Punch in/out recording. (NEW) * Session/project template support. (NEW) * Current track auto-monitoring. (NEW) * MIDI buses now supporting multi-timbral instrument plug-ins. (NEW) * Individual clip gain/volume, normalize and audio/MIDI file export. (NEW) * Copy/paste to desktop environment clipboard. (NEW) * and many, many fixes and new bugs ;) Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball http://downloads.sourceforge.net/qtractor/qtractor-0.3.0.tar.gz - user manual http://downloads.sourceforge.net/qtractor/qtractor-0.3.0-user-manual.pdf Weblog (think 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 libsndfile). - 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. - MIDI clip editor (matrix/piano roll). - MIDI instrument definitions (a-la Cakewalk(tm)) - JACK transport sync master. - MMC control surface enabled. - Configurable keyboard shortcuts. Change-log: - Almost complete rewrite of the plugin configuration and parameter initialization logic. - MIDI bank/program selection is now taken into account on plugins initialization and replication. - Fixed initial parameter values for native VST plugins. - Track form plugin lists are now properly (re)initialized when track type changes. - Generic plugin forms now have the option to show/hide the parameter widgets through the new "Params" button. - New auto-monitor toggle option (menu Track/Auto Monitor): the current selected track is now set on monitor and MIDI channel omni-mode automagically, as a convenient workflow feature (kindly suggested by Holborn). - MIDI clip editor Tools menu is not disabled anymore when there's no selection, drop-down menu items are instead. - Make all recorded clips to honor either the punch-out or play-head accumulated position; resolve all pending MIDI sequence note events on record stop/close. - Major silent move: audio plugins chain are now applied in a pre-fader/meter basis as is usually implied from the mixer strip layout ie. signal flows from the top to the bottom. - All MIDI buses may now have plugins inserted so that multi-timbral synth/sampler plugins get driven to their fullness. - MIDI track plugin's dedicated audio output bus may now be effective, as it seems, good old master audio output bus was being used, no matter what. - Paste-repeat command has been introduced, now allowing to replicate and concatenate the clipboard contents over the time-line, with a given repeat-count and optional period (see menu Edit/Paste Repeat... on the main and MIDI clip editor windows). - Normalize tool on MIDI clip editor got rewritten from its previous brain dead, useless and utterly wrong operation. - All time offsets and lengths are now zero-bar/beat based when displayed in the BBT (bar.beat.ticks) format. - MMC STEP gets adjusted to current snap-per-beat setting. - Fixed broken initial buffering that was randomly crippling those audio clips that fit integrally in cached and while on playback. - Fix initialization of multiple instances of DSSI plugins which implement run_multiple_synths (eg. fluidsynth-dssi), preventing an instant crash on activation. - Exclude deprecated VST elements from compilation. - Export tracks dialog has new punch in/out range option. - Somehow realized that looping and punch-recording are two mutually exclusive states, at least until loop recording (ie. takes) gets real. - Fixed bug #2249291 - Crash on tempo change; affecting the WSOLA based time-stretching on all non-stereo audio clips. - Incomplete audio peaks were being cached prematurely, fixed. - Make way for paste/dropping items from the system clipboard over the main track view. Cut/Copy/Paste/Delete of file items have now this workaround fixed, wrt. Files widget keyboard shortcuts, respectively. - Clip gain/volume propriety is now in place and reflected in audio clip waveform drawing in particular. - A new hideous progress bar is now lurking in the main status line, as found convenient to display progress of the also new clip tools (normalize, export, etc.). - Clip normalize tool is now available (Edit/Clip/Normalise). - Audio and MIDI clip file export is now available as a tool (see Edit/Clip/Export...). - Punch in/out (range) recording is now in experimental shape, with minimal settings and functionality, already accessible through the main menus, transport toolbars and visible on main tracks view and MIDI editors as magenta colored line markers. - External MIDI control events for channel volume (7) and channel panning (10) are now handled properly through session tracks. - Session file templates make its debut with new usability option, on whether new sessions are created based on existing template file (see View/Options.../Display/Session/New session template; nb. session templates are just regular session files but loaded and saved with no media content (no clips nor files). - Grayed/disabled palette color group fix for dark color themes. - Implicit attempt to flush all pending notes for some, if not most plugin instruments (eg. VSTi), on playback stop. - Fait-divers: desktop menu file touched to openSUSE conventions. - Internal refactoring alert: Session and Options instances are now being redesigned as singletons, preparing to get out of the way from the master GUI/MainForm instance. - Clip drawing methods refactored so let the fade-in/out handles get seen with transparency over the clip graphics content. - Reset and continue looping even still when continue past end transport option is not set and playback is rolling. Hope it makes through a Happy New Year with flying colors ;) Cheers && Enjoy! -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

Small audio app's, examples with GUI toolkit 'SDL-widgets'

by W.Boeke

Hi, As you may know there exists a cross-platform graphics library called SDL. It is mainly used for games, but it is excellent for normal app's also. Some time ago I wrote a GUI toolkit on top of SDL, called SDL-widgets. It is far from complete, because I focussed on 2 example audio applications, that might also be of interest for visitors of this newsgroup. The first example app is called make-waves. It can: - draw waveforms to the screen, modulate them by each other, you can listen to the result, - draw a physical model of a string or a spring that you can listen to and animate with the mouse, - draw and edit the harmonic spectrum of a sound, - display the frequency curve of digital filters, that you also can plug in yourself. The 2nd example app, wav2spectrum, can read a wave file and perform FFT analysis on it. You can scroll through the cached waveform chunks and FFT spectra easily. I tried to document the toolkit and the examples fairly well, so maybe they have some use for others as well. You can get it from: http://members.chello.nl/w.boeke/SDL-widgets/index.html Kind regards, Wouter Boeke

Vamp plugin SDK v2.0 now available

by Chris Cannam

Version 2.0 of the Vamp plugin SDK is now available. http://www.vamp-plugins.org/ Vamp is a plugin API for audio analysis and feature extraction plugins written in C or C++. Its SDK features an easy-to-use set of C++ classes for plugin and host developers, a reference host implementation, example plugins, and documentation. It is supported across Linux, OS/X and Windows. A documentation guide to writing plugins using the Vamp SDK can be found at http://www.vamp-plugins.org/guide.pdf. == What's new in 2.0? * Each returned feature can now specify a proper duration as well as start time, value array, and label. * A new PluginSummarisingAdapter is provided in the host SDK, permitting hosts to easily obtain summary results such as averages based on a plugin's returned features. * An RDF ontology is provided for the description of Vamp plugin capabilities and configurations (see http://omras2.org/VampOntology). * The SDK libraries have been reorganised so as to draw a clearer distinction between plugin and host SDKs. * Better platform-specific build documentation is provided (in the build directory), particularly for MSVC builds which now also feature project files for the example plugins. * Two new example plugins have been added (Simple Power Spectrum and Fixed Tempo Estimator). * The command-line host provided now has an extra-informative plugin information listing option (--list-full). == Backward compatibility A detailed compatibility statement is included in the SDK, but to summarise: * Plugins and hosts built with 1.x and 2.0 SDKs are mutually compatible. You can load old plugins in new hosts and new plugins in old hosts. * Plugins written for 1.x can be compiled against 2.0 without modification. * Hosts written for 1.x will require some changes to #include directives, but most hosts should compile against 2.0 without other modifications. * Although the plugin binary interface is compatible with 1.x, the SDK libraries are not binary compatible with the 1.x libraries. Plugins and host code will need to be recompiled if they are to be updated to 2.0, not just re-linked. == Credits This work was carried out at the Centre for Digital Music, Queen Mary, University of London. It was funded by the EPSRC through the OMRAS2 project EP/E017614/1. See http://omras2.org/ for more information. Chris

Rivendell v1.2.0

by Fred Gleason

On behalf of the entire Rivendell development team, I'm pleased to announce the release of Rivendell v1.2.0. 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 *** Changes: RDCatch Download Events. An 'Event Offset' setting has been added to Download Events to allow date wildcards used in the URL field to be offset by the indicated number of days. Hard Time Handling in Logs. The logic for processing hard start times in logs has been changed so that a hard time event will be executed when wall clock time matches regardless of it's place relative to other hard timed events. Now & Next Changes. A new plugin architecture has been added that makes it possible to create "Rivendell Loadable Modules" (RLMs for short) that can be used to generate Now & Next PAD data to a wide array of external devices and services. Runtime plugin configuration is accomplished in RDAdmin->ManageHosts->RDAirPlay->ConfigureNow&Next. A set of sample plugins is provided for transmitting data via UDP and serial ports as well as for interfacing to 'social networking' services such as Twitter and FaceBook. Information on writing new plugins can be found in the 'rlm.h' header file. Dropbox Changes. Several new dropbox features have been added, including the ability to configure a box not to delete source files after import (particularly useful in conjunction with satellite-based audio delivery services such as AMB-OS and PRSS ContentDepot). Also new is the ability to apply an automatic date offset to any encoded Start or End Date value of imported files. Automated System Management. It is now possible to configure various objects to be automatically purged from the system after they expire. For audio cuts, this can be configured on a group-wide basis in RDAdmin->ManageGroups, while Logs and ELR data purging can be configured in RDAdmin->ManageServices. RDLogManager Enhancements. A 'Remarks' field has been added to the Event and Clock dialogs to provide an area for entering free-form text notes. GPIO Enhancements. It is now possible to configure separate and independent macro carts to execute upon the rising and falling state of a GPIO line. Username Length. The previous limit of a maximum of eight characters in a Rivendell username has been increased to 255, thus allowing for better integration with external authentication systems such as Active Directory. Bugfixes. Several bugfixes have been implemented -- see the ChangeLog for details. Database Update: This version of Rivendell uses database schema version 170, 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.
