Hello everyone, I'm trying to install and use zita-jacktools, but unfortunately I don't get it to work. https://media.ccc.de/v/lac2018-46-jacktools_realtime_audio_processors_as_py… I managed to compile it and install it. According to http://linux-audio.4202.n7.nabble.com/zita-jacktools-available-now-td106280…, I needed also to compile zita-convolver 4.0.0 first, which I did, and which also went well. I've done the following: 1. download and unpack: - zita-audiotools - zita-jacktools - zita-jclient - zita-convolver 4.0 2. make and install zita-jclient and zita-convolver: - go to source, them make, then sudo make install 3. install zita-audiotools and zita-jacktools: - go to folder, then python3 setup.py build - then install with sudo python3 setup.py install Now I can import jacktools in Python without errors. But if I try to use it OR to run an example file (e.g. tobspect.py like in the ccc video), I get the following error: ImportError: libzita-jclient.so.0: cannot open shared object file: No such file or directory In the nabble thread, a user said that zita-jclient is installed to /usr/local/lib64, but zita-jacktools only included /usr/lib as the library path. So I copied libzita-convolver and libzita-jclient from /usr/local/lib64 to /usr/lib, but I still get the same error message. Does someone have any hint? I'm developing a open source Python application, where I really need fast and rock solid interpolation for the mixer faders, so I'd really love to use JackGainctl for this.... Here the full error message: File "/media/sda7/Programming/Python/jacktooltest/main.py", line 3, in <module> from jacktools import jackkmeter File "/usr/local/lib/python3.6/dist-packages/jacktools/jackkmeter.py", line 22, in <module> from jacktools.jackclient import JackClient File "/usr/local/lib/python3.6/dist-packages/jacktools/jackclient.py", line 21, in <module> from jacktools import jackclient_ext ImportError: libzita-jclient.so.0: cannot open shared object file: No such file or directory Thank you for any help! All the best, Vince

Looking for interested developer - TonePrint editor & TC Electronic Plethora X5

by Mark Knecht

Hello, TC Electronic has a lot of pedals that use their toneprint technology. They have recently released a new device called the Plethora X5 which slots 5 TC pedal 'models' into a single virtual 'board' and supports 128 'boards' stored in the Plethora. Visit YouTube for a plethora (sorry) of videos on the device over the last couple of months. I purchased one of these devices. It works well (so far). It's Linux internally running 4.9.47-rt37. Sadly there are a couple of rather disappointing issues: 1) Nothing new but TC doesn't support Linux with their TonePrint editor. I see some reports of users running the app with Wine but I cannot be bothered to do that so I'm using it on a Win10 laptop where my excessive Native Instruments investments reside. This is manageable but not preferable for me. 2) The biggest issue - there is apparently no way to back up your settings which reside in the Plethora X5. The TonePrint editor communicates with the Plethora over USB or BlueTooth but apparently acting as little more than a monitor. You can create and edit settings for each of the 5 pedal models you are running in a single board but it seems the only way to store them is in the Plethora itself. My (very limited) initial investigation leads me to believe that there are no data files left on the Windows machine and all data is only in the Plethora X5. Therefore, be it fire, theft or accident, if something goes wrong with your Plethora all of your personally created sounds are lost. (I'm waiting for confirmation of this from TC Electronic but so far I cannot see why this wouldn't be true.) Anyway, I'm not a coder but I am technical. If there's someone out there with an interest of working on some sort of Linux TonePrint support please get in touch. Cheers, Mark Knecht markknecht(a)gmail.com

Tascam US-4x4 Utils

by Guy Sherman

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

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.
