Hi All, On this page (https://wiki.linuxaudio.org/wiki/hardware_support) the Tascam US-4x4 is listed as "*supported* There is a Windows and Mac configuration program, but it doesn't control much." I own one, and recently discovered that one of the things that is quite important if you need four distinct outs is controlling the output routing of the line outputs; without the Windows util, basically all the signals coming in from the PC are mixed together, along with inputs from the preamps (based on the Monitor Balance knob), and then the output is sent as stereo pairs out both of the pairs of line outputs. So, I kinda reverse engineered their USB protocol a bit, and wrote a tool to let you configure the outputs. You can find it here: https://github.com/guysherman/tascam-util Anyway, maybe that will help someone else out. Also, if anyone who maintains the Wiki can let me know how to update that hardware support page, I can link this util from there. Happy composing/recording/mixing/listening! Guy. -- Guy Sherman *w: *http://guysherman.com

desktop icon, wm, desktop and audio software [kind of collective bug report]

by Dominique Michel

Hi all, First, I will thank you all for all the great software you make. I am both a musician and the chief developer of fvwm-crystal http://fvwm-crystal.sourceforge.net/ I am very concerned with the look and feel of my desktop. Many audio software are providing both a desktop file and an icon file. The desktop file contain an Icon field of the form which is fine. That field is used by all Freedesktop compliant desktops in order to know the icon to display into the application menu. https://specifications.freedesktop.org/desktop-entry-spec/latest/ar01s06.ht… Until then, fvwm-crystal and all other compliant desktops will find and display your software with its icon into their application menu. When running a software in X, most desktops can use 4 wm hints to know the names of the software window and of its icon, for things like the text to display into the title bar of the window or into the taskbar, or the icon to display into the pager or icon manager if any. Here, fvwm-crystal and other desktops are in trouble with a lot of audio software, that because these wm hints are not consistent with their icon name and the desktop fail to display their icon. These 4 files are "Name, "Icon Name", "Class" and "Resource". At least one of them must match the icon name provided by the application, otherwise many desktops will not know which icon to display outside of the application menu. As example, after starting radium, I get: Name: ** Radium - New song. ** Icon Name: ** Radium - New song. ** Class: radium_linux.bin Resource: radium_linux.bin when the icon provided by radium is radium.png. fvwm-crystal (and other wms/desktops as well) will not find the icon and display garbage instead in places like pager or icon manager. If at least one of these hints was just radium, it would just work fine. Name is the text displayed into the tittle bar and task bars. Icon Name should be appropriated but many software don't use it. Many software are using Class or Resource. Normally it doesn't matter which one a software is using, as long than at least one of them match <icon_name_without_extension>. https://tronche.com/gui/x/icccm/sec-4.html I publish related style workarounds in fvwm-crystal for many audio software (just for that, it must be the desktop that have the best support of the linux audio software), but it is so much of them out there, and I just have a lot of other things to do than to test them all, or to report that issue to all of the ICCCM WM-HINTS non compliant ones. So please, consider to check your software for that issue and apply some fix when appropriated. A lot of desktop users will like such fixes. Best, Dominique

[ANN] Qtractor 0.9.14 - A Mid-Spring'20 Release

by Rui Nuno Capela

Congratulations! No matter what others say, you are here and that's awesome! You are also here kindly reminded to update to the very latest and greatest. There's no better time for just that than pretty much now! And now this: Qtractor 0.9.14 (mid-spring'20) is out! Notwithstanding some nasty crash-bugs being squashed--hopefully for good--changes for this mid-season release are as follows: - Export file type, format and quality are now specific options on the Track/Export Tracks.../Audio, MIDI dialogs. - LV2 plug-in UI GTK2 and X11 in Qt5 host native support in addition and alternative to libsuil. - Generic plug-in/Properties... dialog now showing each parameter/property automation status on a /skeuomorphic/ aka. /fake/ and tiny LED ;) - LV2 Plug-in Patch parameter/properties automation and MIDI Controller assignment/learn are now a possibility. - LV2 Atom/Port-event host notification support has been implemented (unofficial). - Fix clean-up of any recording leftovers. - JACK Transport latency is now taken into account for recording latency compensation. - Attempt to force correct audio clip offsets due on recording latency compensation are not quantized to MIDI metronomic time-scale anymore. - LV2 Plug-in MIDNAM support introduced. - Use Shift or Ctrl keyboard modifiers with the mouse- wheel to change any Direct Access plug-in parameters (issue #257). Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

linuxaudio.org maintenance 2020-03-29

by Jeremy Jongepier

Dear all, Today I'd like to perform maintenance on the linuxaudio.org web server around 20:00 CEST. Maintenance comprises moving from GlusterFS storage to disk storage in order to improve performance of the web server. GlusterFS seemed promising but through time we came to realize it's not optimal for our situation. Maintenance will take approx. 3 hours. During that period the sites hosted on the web server won't be reachable as I'd like to shut down all services before doing a final rsync. Thanks for your understanding. Best regards, Jeremy

[ANN] Qtractor 0.9.13 - A QStuff* Spring'20 Release batch #3

by Rui Nuno Capela

Greetings, just one third time! Qtractor 0.9.13 (spring'20) is released! Change-log: - All meters background color are now customize-able (cf. View/Options.../Display/Meters, color level "Back"). - Automatic mixer grid layout (multi-row) is now in effect permanently--being an option no more. - Always show plugins and meters on track list/left pane as permanent standard now. - LV2 UI Request-value feature/interface support has been implemented. - Audio output monitoring meters are now shown/hidden auto-magically on MIDI tracks and/or buses--no need for some user preference option anymore (ie. View/Options.../Plugins/Instruments/Show audio output monitoring meters, is now gone). - Default track height has been slightly increased. - Track / Duplicate Track... now also takes a MIDI track's audio meters setting into account. - VST3 plug-in support introduced. (EXPERIMENTAL) - Fixed first bar/measure position drawing on the time-scale/grid across time-signature changes on the MIDI clip editor (aka. piano-roll) (hopefully fixing issue #245). - Plugins and meters on track list/left pane, are now being set on as default--maybe going stapled in some near future ;) - Make man page compression reproducible (after request by Jelle van der Waa, while on the Vee-Ones, thanks). - Avoid resetting top or left position when zooming with mouse pointer is in main tracks or MIDI clip editor (piano-roll) views. - Make libaubio a build dependency on Debian/Ubuntu; also fix cross-build check to sizeof(float). - Bumped copyright headers into the New Year (2020). Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

New AMB plugins

by Fons Adriaensen

Hello all, Two new sets of AMB plugins are available at <http://kokkinizita.linuxaudio.org/linuxaudio/downloads/index.html> AMB1-plugins: First order panners, Z-axis rotation, and dominance. HOA3-plugins: Third order panners, Z-axis rotation, converters for SN3D to/from N3D and FuMa. See the README for details. All of them now use the 'Ambix' format and gains (except of course the convertors at the non-SN3D side). Ambix format uses ACN channel order, as does Ambdec. So e.g. Ardour master outputs will be in the same order as Ambdec inputs, but channel numbers are offset by 1, for example: Ardour master Ambdec input ---------------------------- 1 in.0 (W) 2 in.1 (Y) 3 in.2 (Z) 4 in.3 (X) If you use these with Ambdec, don't forget to check the 'Input scaling' in the configuration dialog. This should be set to 'SN3D'. If necessary, change, apply and optionally save the preset. -- FA
