The Drummer's Gigsaw: upgrade + BOOGIE-BASE.

by Philippe Hezaine

Hi all, I'm not goaded you and the Gigsaw is not a catapult, but there was a bug about ride bell (rb) hence a new version. You must DELETE or RENAME the old installed version before you'd decompress the new one. http://philippe.hezaine.free.fr/spip.php?article46 By the way there is a BOOGIE-WOOGIE BASE now. http://philippe.hezaine.free.fr/spip.php?article38 Have fun. -- Phil.

The Drummer's Gigsaw: CHA-CHA-BASE.

by Philippe Hezaine

Hi all, No! No! No! I'm not goadING you (oh! My God!) and the Gigsaw is not a 'Pata cult (see http://en.wikipedia.org/wiki/%27Pataphysics ) -Hé! may be a good old slingshot though - but still there is a new BASE. You'll find CHA-CHA-CHA BASE here: http://philippe.hezaine.free.fr/spip.php?article39 I Promise I no longer post on the list until the next week otherwise I'm heading for disaster. (for good!) Have fun! -- Phil. Superbonus-Project (Site principal) <http://superbonus.project.free.fr> Superbonus-Project (Plate-forme d'échange): <http://philippe.hezaine.free.fr>

Re: [LAU] [LAD] So what's the deal with controlling the aeolus organ?stops via midi

by Clemens Ladisch

David Robillard wrote: > Not enough context quoted to tell; are the stops in Aeolus really too > complicated to be controlled via controllers and programs? No: For 55 or so organ stops, you'd need 55 boolean controllers; this can be easily done with NRPNs. Best regards, Clemens

Sonic Visualiser v1.7 now available!

by Chris Cannam

Sonic Visualiser is an application for inspecting and analysing the contents of music audio files. It combines powerful waveform and spectral visualisation tools with automated feature extraction plugins and annotation capabilities. Version 1.7 of Sonic Visualiser is now available. http://www.sonicvisualiser.org/ This release contains a number of new features, enhancements, and bug fixes. For more details, please read the release notes at: https://sourceforge.net/projects/sv1/files/sonic-visualiser/1.7/CHANGELOG/d… Sonic Visualiser contains advanced waveform and spectrogram viewers, as well as editors for many sorts of audio annotations. Besides visualisation, it can make and play selections based on the locations of automatically detected features, seamlessly loop playback of single or multiple noncontiguous regions, synthesise annotations for playback, slow down playback while retaining display synchronisation, and show the ongoing alignment in time between multiple recordings of a piece with different timings. Sonic Visualiser supports the Vamp plugin API for plugins that extract descriptive or analytical data from audio.

[ANN] Qtractor 0.4.3 (fussy doula) released!

by Rui Nuno Capela

Fall is upon us. Summer is gone. Trivial speaking, as it marks yet one's another birthday, mine that is. It also marks the approaching bankruptcy of this funny F&D release code-names. One can also think as the last and stable release before a probable next generation do break all loose. Automation and full MIDI control is popping up over the horizon. So take all children home and be prepared for the worst. Nah, don't be that afraid. With some help from good friends, everything can and shall be arranged. No second thoughts. No hard feelings. Meanwhile... Qtractor 0.4.3 (fussy doula) released! Release highlights: * Audio send/return aux. inserts (NEW) * Mixer peak meters gradient eye-candy (NEW) * MIDI System Exclusive (SysEx) setup manager (NEW) * MIDI Playback/Queue timer resolution option (NEW) * MIDI Instrument definitions from SoundFont 2 files (NEW) * MIDI Output bus default instrument (NEW) * Buses dialog manager update (FIX) * Plugin references by label (FIX) * First audio metronome beat/bar (FIX) * Ghost clip selections (FIX) * Overlapping MIDI clips (FIX) Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball: http://downloads.sourceforge.net/qtractor/qtractor-0.4.3.tar.gz - source package (openSUSE 11.1): http://downloads.sourceforge.net/qtractor/qtractor-0.4.3-1.rncbc.suse111.sr… - binary packages (openSUSE 11.1): http://downloads.sourceforge.net/qtractor/qtractor-0.4.3-1.rncbc.suse111.i5… http://downloads.sourceforge.net/qtractor/qtractor-0.4.3-1.rncbc.suse111.x8… - binary packages (Ubuntu 8.04 LTS): http://downloads.sourceforge.net/qtractor/qtractor_0.4.3-1.rncbc.ubuntu804_… http://downloads.sourceforge.net/qtractor/qtractor_0.4.3-1.rncbc.ubuntu804_… - binary packages (Ubuntu 9.04): http://downloads.sourceforge.net/qtractor/qtractor_0.4.3-1.rncbc.ubuntu904_… http://downloads.sourceforge.net/qtractor/qtractor_0.4.3-1.rncbc.ubuntu904_… - user manual (ever still outdated): 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: - External preset files are not removed nor deleted from the file-system anymore. - Connections support for UTF-8 encoded client/port names. - Force track and clip properties dialog widget to be modal as it should from their beginning dawn. - Audio effect send/return aux. inserts are implemented as special pseudo-plugins (Plugins/Inserts). - Reset play-head position on auto-backward and keep playback rolling when continue past end transport option is not set. - MIDI clip editor (aka piano-roll/matrix aditor) gets better on the virtual piano keyboard eye-candy side of things ;). - Plugins are now also referenced by label, avoiding plugin index clash/misses eg. when plugin object file/path changes or is moved externally. - Keyboard focus is now cleared/reset from the main toolbar time and tempo spin-boxes when editing gets finished (eg. Enter key is pressed). - First audio metronome beat/bar now played back correctly (fixes bug #2841437). - Client to/from port (dis)connections now found consistent as good ol'QjackCtl behavior (fixes bug #2834657). - All dirty open MIDI clip editors are now prompted to save before the main application closes (fixes bug #2835516). - Mixer level meters get their long deserved gradient look. - Fixed any ghost clip selections that were haunting the main track view, specially after undo/redo. - Increased tolerance on reading corrupt MIDI files (SMF). - A MIDI SysEx manager is being finally introduced, in some primordial rather basic form though. MIDI System Exclusive (SysEx) event strings may now be freely assigned to MIDI output buses only, allowing for proper setup of external outboard MIDI equipment. Each bus may have an unlimited SysEx queue that gets sent out on every connection change (see View/Buses.../MIDI/SysEx...). - A default MIDI instrument name may now be assigned to any MIDI output bus (see View/Buses.../MIDI). - More legacy headers, stdio.h and stdlib.h, are yet again necessary to build with gcc/g++ >= 4.4 (as patch noted by Alexis Ballier on Gentoo bug report #274168, thanks). - Bus manager dialog (View/Buses...) gets new columns on the left pane buses list as for displaying number of channels and bus mode. - Crash when updating bus probably fixed (bug #2811630). - Fixed glitch displaying beat snap/grid lines on MIDI clip editor, incidental to clips located at absolute zero time. - Overlapped MIDI clips were rendering garbled note events to DSSI/VSTi plugins, now fixed. - New MIDI Playback/Queue timer (resolution) option is now available (see View/Options.../MIDI). - MIDI instrument definitions may now be imported from plain SoundFont files. Cheers && Enjoy. -- rncbc aka Rui Nuno Capela rncbc at rncbc dot org http://www.rncbc.org

which audio synthesis environment?

by Grammostola Rosea

Hi, How to choose a audio synthesis environment? Why and when Pd, Supercollider or Csound? And why do you use Chuck Atte? Just for orientation... \r

The kind of image I'd use on my blog, but, haven't found an occasion for it, so why not just pass it along: http://www.flickr.com/photos/pilax/57002123/ -ken

Re: [LAU] MTC syncing Ardour to hardware sequencer as a slave

by sonofzev＠iinet.net.au

So you do have the MTC/SMPTE chip installed. I don't believe it responds to MTC otherwise.

Fedora 11 + pyjack + blender

by Patrick Shirkey

Hi, I'm trying to get the pyjack patch to work with blender. I'm using a Fedora 11 machine for this test. Unfortunately Fedora packagers have to compile the official blender package without ffmpeg support so it is fairly useless for my specific requirement of editing video with Blender. I have the latest binary from the Blender site which is compiled for python 2.6.2. Fedora 11 comes with python 2.6 Python 2.6 (r26:66714, Jun 8 2009, 16:07:29) I'm not sure if that is 2.6.2 or not. However the blender binary cannot find python on my system at all. I guess because it is installed in /usr/lib64 instead of /usr/lib/ and or the included python libs are overriding my system settings for some reason. If I set the python path to /usr/lib64 or /usr/lib64/python2.6 then I get nothing. If I set it to /usr/lib64/python2.6/site-packages/ which is where the pyjack script is installed I get a crash. If I run python by itself it tells me that it can find the correct paths. ================ #python Python 2.6 (r26:66714, Jun 8 2009, 16:07:29) [GCC 4.4.0 20090506 (Red Hat 4.4.0-4)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> print sys.path ['', '/usr/lib64/python26.zip', '/usr/lib64/python2.6', '/usr/lib64/python2.6/plat-linux2', '/usr/lib64/python2.6/lib-tk', '/usr/lib64/python2.6/lib-old', '/usr/lib64/python2.6/lib-dynload', '/usr/lib64/python2.6/site-packages', '/usr/lib64/python2.6/site-packages/Numeric', '/usr/lib64/python2.6/site-packages/PIL', '/usr/lib64/python2.6/site-packages/gst-0.10', '/usr/lib64/python2.6/site-packages/gtk-2.0', '/usr/lib64/python2.6/site-packages/scim-0.1', '/usr/lib/python2.6/site-packages'] ================ So ideas on why the blender binary is failing here and how to fix it would be welcome. Also if anyone can recommend a quick way to test pyjack to make sure it is installed properly that would also be handy. Cheers. -- Patrick Shirkey Boost Hardware Ltd

The Drummer's Gigsaw: BLUES-BASE (testing)

by Philippe Hezaine

Hi all, I publish this BLUES-BASE in a relatively rough state for two reasons: Firstly you can try more deeply the Gigsaw as it's explained in the README+Tutoriels. I assume and believe it's working for you though I still get a single feedback from a guy running AV Linux. Good news! It is positive. ;=) Secondly because so far I'm not totally fixed about the way to sort out the patterns. Well! It's a Jigsaw. How to sort out a jigsaw? (I wanted to talk with my psychoanalyst but he only speaks in Lisp language.) From my experiences I reach the point as follows: A BASE is organized in 5 groups if they exist: 1. SIDESTICK (ss) 2. ACOUSTIC SNARE (sna) 3. ELECTRIC SNARE (sne) 4. Others sounds (if they exists without snares ) 5. COLOR of SOUND (sounds mixed together. ex: sna + sne + tamb) Each group is subdivided as follows (if they exists): Ex. for ACOUSTIC SNARE SNA + HIHATS sna hhpedal sna hhclosed sna hhc + hhopen sna hho alone SNA + CYMBALS sna cymra or cymrb SNA + PERCUSSIONS sna tambourine sna cabasa sna cab maracas ... etc... I would be glad if someone has an opinion about this classification. Hum... Ideas, opinions, suggestions, drawbacks are welcome. :=) It's useless to download again the last Gigsaw.tar.bz2 (01-10-2009) if it works for you. Just download the BLUES-BASE and put it in the "Bibliotheque". And play with it in your workroom, i.e in MA-BASE after you have pasted and renamed MY-SONG-blank.ly. Hereby I present a underground dedication to Dave Phillips who loves the blues. You'll find the BLUES-BASE here: http://philippe.hezaine.free.fr/spip.php?article36 Have fun. -- Phil.
