Announcing synthclone-0.1.0

by Devin Anderson

After almost two years, I'm happy to announce that a new version of `synthclone` is available for download! The new version of `synthclone` is a complete departure from the utility application I wrote two years ago on a rainy weekend. Here are the most important changes: - `synthclone` is now a Qt-based application with a table interface that allows a user to configure sample times, release times, notes, velocity values, aftertouch, channel pressure, and MIDI control changes on a zone-by-zone basis. You can tweak the parameters and audition samples until you're satisfied with the samples you've acquired. - The application is now session-based. Sessions can be saved and restored. - `synthclone` comes with `libsynthclone`, a plugin API that allows developers to write plugins that can interact with and extend the application. Developers can add components to `synthclone`, including sampler components (for sending MIDI and acquiring audio data), effect components (for altering audio data), and target components (for writing patches that work with software that can play back sample-based instruments). In addition, the API allows plugins to do almost anything that the application itself can do. All changes to the session are accessible via the observer pattern (using Qt signals and slots), allowing plugins to easily sync to session changes. - `synthclone` is distributed with several plugins: 1.) libsynthclone_hydrogen - Builds Hydrogen drumkits. 2.) libsynthclone_jack - Sampling via the JACK Audio Connection Kit. Includes JACK Session support. 3.) libsynthclone_sfz - Builds SFZ instruments. 4.) libsynthclone_trimmer - Trims "silence" off of the start and end of acquired samples. 5.) libsynthclone_zonegenerator - Generates zone data for acquiring samples. - The application can write multiple targets (i.e. Hydrogen and SFZ) in one session. No need to restart `synthclone` and wait while samples are reacquired. The new version of `synthclone` is available at: http://synthclone.googlecode.com/ This is an alpha release. Please report bugs using the issue tracker: http://code.google.com/p/synthclone/issues/list If you like `synthclone` and have ideas that can make it better and/or want to keep up with its progress, join the users group: http://groups.google.com/group/synthclone-users If you're a developer and want to write plugins for `synthclone` or contribute to the application itself, join the development group: http://groups.google.com/group/synthclone-development On a closing note, I'd like to thank Peter L. Jones for patiently answering my questions about the SFZ format. With his help, I was able to understand far more about the SFZ format than I ever could using the official documentation. Thanks, Peter! -- Devin Anderson devin (at) charityfinders (dot) com CharityFinders - http://www.charityfinders.com/ synthclone - http://synthclone.googlecode.com/

Qtractor 0.5.1 - The Bravo Yankee return!

by Rui Nuno Capela

Howdy, Summer is now long gone, obviously fall has already begun. As winter looms on the horizon the year steadily marches into its due end. (oh crap!...) Today marks the day of this second public release while on the TYOQA age. It also marks yet another birthday of mine. One more year's gone, one less to go. Be happy! I hope you'd like my party as soon you get over from yesterday's bitten fruit showtime. Now's the time... Qtractor 0.5.1 (bravo yankee) is out! Yes, it's "bravo" alright, not "beta" nor anything else. Despite any previous existing codename. Now, it's all dumb-down easy to predict any next release codenames, a matter of convergence and fact that just chalks one less of a burden on me :) Believe it or not, this is the best and, allegedly, the most stable release ever. Ain't them all? ;) Release highlights: * Linked (aka. ref-counted) audio/MIDI clips (NEW) * Aux-Send pseudo-plugin (NEW) * Direct-access plugin parameter slider (NEW) * MIDI file player (NEW) * Automatic time-stretching of audio clips on tempo-map changes (FIX) * Improved native Linux VST support (FIX) * Improved JACK-Session support (FIX) * Improved generic plugin form (FIX) * MIDI-fx plugin support (NEW) * Audio bus/ports auto-connect option (NEW) * First translation call (Czech) (NEW) Cheers! Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball: http://downloads.sourceforge.net/qtractor/qtractor-0.5.1.tar.gz - source package (openSUSE 11.4): http://downloads.sourceforge.net/qtractor/qtractor-0.5.1-4.rncbc.suse114.sr… - binary packages (openSUSE 11.4): http://downloads.sourceforge.net/qtractor/qtractor-0.5.1-4.rncbc.suse114.i5… http://downloads.sourceforge.net/qtractor/qtractor-0.5.1-4.rncbc.suse114.x8… - from the paleolithic shelves: user manual: http://downloads.sourceforge.net/qtractor/qtractor-0.3.0-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: - More LADISH support: SIGTERM signal is now trapped for graceful application close. - Improved paste-repeat snap precision when dealing with large repeat counts. - Czech (cs) translation added, by Pavel Fric. - Added a few snap-to-beat divisors (unusual Beat/5, Beat/7, Beat/9 and Beat/10) for completeness sake. - Such a simple change of mind with a visual twist: the "A" track automation button/menu has now been - moved to the right-most, as it belongs ;) - Auto-connection of dedicated audio outputs is now optional for default audio master bus, metronome, player and MIDI instrument plugin dedicated audio outputs. - Finally, after a pitiful large brain-dead period, generic plugin forms are now showing all possible controllable plugin parameters featuring a paged, tabbed dialog, whenever applicable. - Special hack/fix for JUCE based native VST plugins, which are the most actually found with a GUI editor, skipping explicit shared library unloading and thus avoiding some mysterious crashes on session close and/or application exit. - Support for MIDI-fx plugins (native VST and/or LV2) is now implemented and functional (intra-chain only). - Instrument plugin bank/program selection was found broken or dead in the water, specially on VSTi, now finally fixed again. - VST plugin parameter value display on generic form is now back in business (were dead regarding value changes). - All plugin's provided GUI editors are now honored by being popped up first, instead of the usual but good old generic plugin form. - Long overdue implementation of a dedicated MIDI file player is now accessible from the MIDI files widget; one can play the whole SMF or just a single track or channel. - Update to a newer VeSTige header, probably fixing an old 32 vs. 64 bit mismatch. - Avoid JACK session filenames/paths to be ever shown; also avoid all buses ports (re)connections when JACK sessions are (re)loaded, given the fact that session management will take care of just that; more also, untitled/default session names are now also picked up to match current LADISH project name, obviously given by LADISH_PROJECT_NAME environment variable, whenever present (as suggested by Nedko Ardaunov). - Paste-repeat floating selection has been fixed (was showing only the last repeated selection). - Coherence of tempo changes on audio and MIDI clips, whether automatic time-stretching is in effect, has been slightly improved, hopefully fixed. - Bold attempt to get linked (aka. ref-counted) audio and MIDI clips into practice (EXPERIMENTAL). - Main track view now showing all clips above the grid. - Added support for both new and older (deprecated URI) lv2_external_ui extension (by Nedko Ardaunov). - Following yet another great idea, and implementation, by Holger Dehnhardt, who already brought us the new aux-send insert plugin, thanks again, the so-called direct access control option is now featured for any plugin parameter right from plugin listings eg. mixer strips. - General resource consumption and management has been slightly improved, due to internal buses allocation optimization. - Fixed nasty crash-bug that was severely affecting all sessions that had at least one insert (pseudo-)plugin on any audio input bus. - All automation curve nodes are now relocated whenever disparate session sample-rate is detected on load. - New aux-send/insert pseudo-plugin is now introduced, allowing to route any track audio output to any other audio output bus besides the nominal one -- thanks to an original implementation from Holger Dehnhardt. - New immediate edit/loop-range settings from current clip extents, accessible on the main menu (Clip/Range Set, Loop Set) and from MIDI clip editor menu as well (File/Range Set, Loop Set). - MIDI Names XML files (*.midnam) may now be imported into MIDI instrument definitions. (EXPERIMENTAL) - Avoid cursor reset while editing MIDI events list (fixes bug #3380259, reported by Frank Neumann). - Just some typos fixing (patch #3378382 by c-korn). - Track view automation curve editing mode has been slightly fixed, now allowing for other previously existing point-and-click mouse operations. - Default automation curve mode is now preserved (following a suggestion by Alexandre Prokoudine, thanks). Enjoy! -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

[ANN] JACK 0.121.3 + D-Bus (jackdbus)

by Nedko Arnaudov

Apart from the usual jackdbus addition, this release contains fix for xrun reporting. This release provides both the new jackd.py (D-Bus bound and available in the vanilla tarball) and jackdbus. Tarball containing D-Bus patched jack 0.121.3 is available here: http://nedko.arnaudov.name/soft/jack/dbus/ http://nedko.arnaudov.name/soft/jack/dbus/jack-audio-connection-kit-dbus-0.… http://nedko.arnaudov.name/soft/jack/dbus/jack-audio-connection-kit-dbus-0.… A patch against vanilla 0.121.3 is available here: http://nedko.arnaudov.name/soft/jack/dbus/jack-audio-connection-kit-0.121.3… http://nedko.arnaudov.name/soft/jack/dbus/jack-audio-connection-kit-0.121.3… After applying the patch you have to run autoreconf. D-Bus modifications add optional autodetected support for the D-Bus based server control system. D-Bus is object model that provides IPC mechanism. D-Bus supports autoactivation of objects, thus making it simple and reliable to code a "single instance" application or daemon, and to launch applications and daemons on demand when their services are needed. * Simplified single thread model for control and monitor applications. Various D-Bus language bindings make it trivial to write control and monitor applications using scripting languages like Python, Ruby, Perl, etc.. * JACK has log file (~/.log/jack/jackdbus.log) that is available for inspection even when autoactivation happens because of first JACK application is launched. * There is real configuration file used to persist settings that can be manipulated through configuration interface of JACK D-Bus object. * Improved graph inspection and control mechanism. JACK graph is versioned. Connections, ports and clients have unique (monotonically increasing) numeric IDs. * High level abstraction of JACK settings. Allows applications that can configure JACK to expose parameters that were not known at compile (or tarball release) time. Currently there are some minor differences between jack1 jackdbus and jack2 jackdbus: * There is no parameter constraints support (no enums and no ranges) * Settings file (in ~/.config/jack/) is conf-jack1.xml instead of conf.xml, because jack1 and jack2 settings and not really compatible. When configured with D-Bus support, jack_control is installed. jack_control is simple commandline interface for jackdbus. Other tools that can communicate with JACK through D-Bus: * LADItools (tray icon, configuration, etc.) * Patchage (and lpatchage too) * LASH 0.6.x * ladish * QJackCtl -- Nedko Arnaudov <GnuPG KeyID: 5D1B58ED>
