Has anyone got ingen to work recently? I'm running all the latest stuff from Dave's svn repo here, but I'm getting bitten by this bug: http://dev.drobilla.net/ticket/798, which makes it rather unusable (loading patches doesn't work, neither from the command line nor inside ingen). I went back as far as r3829, which still had the same bug. Can anyone recommend a revision that works? I'd really like to give it a go, but without the ability to load patches it's only half the fun. :) Albert -- Dr. Albert Gr"af Dept. of Music-Informatics, University of Mainz, Germany Email: Dr.Graef(a)t-online.de, ag(a)muwiinfa.geschichte.uni-mainz.de WWW: http://www.musikinformatik.uni-mainz.de/ag

Ambisonic Effect processing

by Harry van Haaren

Hi everyone, I'm currently thinking about how to process B-format ambisonic signals. For basic compression, gating, expanding, limiting etc things are relatively simple: process all 4 of the W,X,Y and Z signals. But what bout effects like Reverb: Should that effect only be applied to the W signal? This will change the signal's direction due to the unrelated-ness between the signals. But appling reverb to the directional components will smear any sudden changes in location, or am I missing something here? I'm applying most effects in mono before doing the B-format encode, perhaps all effects like reverb should be placed before that encoding? Open to theory, experience, guesstimates etc :) -Harry

[ANN] Qtractor 0.5.3 - The Delta Whisky natural cask strength!

by Rui Nuno Capela

TYOQA is officially over. Qtractor 0.5.3 (delta whisky) drops from angels share! nuff said :) Impromptu release highlights: * Clip drag-and-move stepping with keyboard arrow-keys (FIX) * Plugin parameter automation GUI feedback (FIX) * LV2 plugin Qt4 GUI support (FIX) * Clip/Split on current play-head location (FIX) Slaintheva! Website: http://qtractor.sourceforge.net Project page: http://sourceforge.net/projects/qtractor Downloads: - source tarball: http://downloads.sourceforge.net/qtractor/qtractor-0.5.3.tar.gz - source package (openSUSE 12.1): http://downloads.sourceforge.net/qtractor/qtractor-0.5.3-2.rncbc.suse121.sr… - binary packages (openSUSE 12.1): http://downloads.sourceforge.net/qtractor/qtractor-0.5.3-2.rncbc.suse121.i5… http://downloads.sourceforge.net/qtractor/qtractor-0.5.3-2.rncbc.suse121.x8… - once upon the time, eons ago: 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: - Fixed initial LV2 plugin UI widget/window titles. - Attempt to get any brand new LV2 plugins Qt4 enabled UI's working on either slv2 and lilv build modes ;) (nailed by falkTX, thanks). - Current clip is ultimately inferred from the one under the play-head position and current selected track; the last one clicked over and/or selected still has precedence (following request by Loiugi Verona). - Drag-moving clips horizontally with the keyboard arrow-keys just got a step better with a fixed minimum of one pixel, depending still on the current snap-per-beat setting and horizontal zoom level (as suggested by Louigi Verona, thanks). - Get maximum and minimum peak values back when drawing audio waveforms.- Automation play/feedback has been missed to show on those plugins that provide their own GUI, now on par with all the rest 'homebrew' widgets (eg. generic plugin properties dialog). - All plugin parameters automation and selection were left inaccessible until the generic native plugin dialog is eventually shown, now fixed (re. bug #3463916). Enjoy && Happy New Year! -- rncbc aka Rui Nuno Capela rncbc(a)rncbc.org

FOSDEM 2012

by Nils

Hello lists, DISCLAIMER: I am not affiliated with FOSDEM. who is going to attend the FOSDEM Open Source Developers meeting in Brussels(Belgium) on 4./5. February? http://fosdem.org/2012/ There is no registration or fee (but you can donate). Since the LAC is in the USA this year maybe not many Europeans have the money to travel there, this could be an opportunity to meet anyway. I think I will go, somebody announced an inofficial Music Notation Meeting on the Lilypond mailing list. Nils

Cheer a loud "Hip Hip,..." to Ico, who made it possible in the first place and send Kudos to Brian Maloney from the vt.edu tech dept for outstanding excellent GNU/Linux support! All systems go. robin

ganv build error: error: ISO C++ forbids declaration of ‘cairo_region_t’ with no type

by Diego Simak

Hi all, I don't really know if this email should be directed to LAD, or LAU or just Drobilla devs... anyway: I'm trying to build Ingen from SVN using all LV2 files (packages, extensions, tools, etc.) from SVN as well. During ganv build stage I'm getting this error: /home/diego/Desktop/ingen/drobilla-lad/ganv/ganv/canvas-base.h:259:2: error: ISO C++ forbids declaration of ‘cairo_region_t’ with no type /home/diego/Desktop/ingen/drobilla-lad/ganv/ganv/canvas-base.h:259:16: error: expected ‘;’ before ‘*’ token .....and the build just fails. I know that there's a ticket 792 [1] opened about this issue but I would like to know if there is some simple solution to solve this error. I'm on Ubuntu 10.04 with libcairo2-1.8.10. Thank you very much. Diego [1]: http://dev.drobilla.net/ticket/792
