[JACK] Can tempo be synced between hosts?

by Francesco Napoleoni

Hi everyone I’m experimenting with netjack (mainly version 1), and I’m quite impressed by its ability to get different machines march together without (at least apparently) hassle. However I cannot find a way to transmit tempo changes from master machine to slaves. I’ll try to explain myself better: the “master machine” is a PC with a soundcard, running JACK on a Linux Fedora OS, and is connected with the “slaves” with a gigabit ethernet link. The “slaves” are currently two, but I would like to expand this to a wider configuration, maybe with devices such as Raspberry sharing the load of multiple synths, effects and so on. The problem is that I can see the start/stop of the Jack transport synced between the hosts, but not the tempo. This limits the use of applications which do make use of tempo changes on slave hosts, forcing me to copy the tempo map to them and run it in a DAW. As a side effect I can see the BBT drifting between hosts (apparently its value is computed using the local tempo mark). Is there a way to solve this problem? Or am I missing something? Thanks in advance cheers Francesco Napoleoni

[Music] Symphony of love illusive

by Jeanette C.

Hey hey, the symphony of love illusive was written using the free Sonatina Symphonic Orchestra (SSO) SFZ library in LinuxSampler. Only when the first two movements were completed did I discover the Virtual Playing Orchestra and so I will have to write something else symphonic some time soon. :) (There are currently only Youtube links, no direct downloads, they will follow within the next few days.) Here are the four movements: 1. Allegro (Fantasia - possibly) https://youtu.be/BC2RuiFDlOw 2. Molto Vivace (Scherzo - nearly and my pride and joy :) ) https://youtu.be/7vNi--527Sk 3. Larghetto (Lament - maybe) https://youtu.be/-FiuTQRRVF4 4. Andante Moderato (Rondo - could be) https://youtu.be/sdYGqnYhyxA Feedback, as ever is appreciated. I know that I was only consistent in one particular: I always broke the form. :) Some more details: the whole symphony was recorded with the Sonatina Symphonic Orchestra. The strings and brass were layered with some - self designed - sounds from my Roland module, to flesh the sound out and have more of a dynamic range available. The symphony was written in Midish, recorded straight to Nama and only little processing was added, mostly to the sounds from the hardware to match them with the software samples.

Need some Ideas for a streaming helper ...

by nik＠parkellipsen.de

Hi! So, i recently started streaming a lecture. The institution uses Discord as a platform. Using a strange mix of PulseAudio and JACK, i managed to get a configuration running where I could stream my voice and the media from my slides (slides were presented using chromium). The problem is that discord seems to have some form of compression/auto-gain that can't be turned off ... so to hear the sound from the videos (the quieter parts especially) I had to crank them way up. But then, my voice was suddenly way to low in volume. So, my idea would be to have a mixer in JACK that allows me to mix my voice and the streaming audio before it goes into discord (via the PulseAudio JACK Source), and in addition allows me to put a compressor on the mix so that the streaming audio and my voice will be at a good level. Does anybody have a hint what could be a good tool here ? Best, Niklas

Hi List, I recorded a workflow demonstration for Patroneo, the "Easy Pattern Sequencer" The video is edited, but still a bit longer. But it should give a good impression how the software can be used. https://youtu.be/pEmKrZQuE8Q Nils https://www.laborejo.org

Parorama T6

by Will Godfrey

I bought this keyboard controller based on the advert stating it was class compliant, plug and play, Linux compatible. However, I found that it starts up with a firmware update message, and apart from Note On, Note Off, Channel Pressure, none of the controls work, not even the ones designated for manually setting the others. On conacting nektar for support, it took over 2 days for them to tell me that I had to install the firmware. WTF! I've never heard of any hardware being effectively dead until you install firmware. What's more, so much for supporting Linux, the software to install the firmware is Windows or MacOs - nothing else. I tried using Wine to get this done, but the software reports that it can't find the keyboard. This is on Devuan Boewulf, which carries Wine V4.0. I also tried grabbing a more recent version of Wine from wineHQ, but devuan refused reporting an uninstallable dependency. I'm very reluctant to try to install a VM, I'm running out of storage space, and this is a working machine - I can't risk messing it about too much. If it weren't for the pandemic lockdown situation I might have been able to go to a Windows using friend for help, but this is out of the question for the forseeable future. Any suggestions? -- Will J Godfrey http://www.musically.me.uk http://yoshimi.github.io Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

by Rui Nuno Capela

Hello again! The 'Vee One Suite' of 'old-school' software instruments, synthv1 [1] as a polyphonic subtractive synthesizer, samplv1 [2] a polyphonic sampler synthesizer, drumkv1 [3] as yet another drum-kit sampler and padthv1 [4] as a polyphonic additive synthesizer, are here and again released as the second batch to the so called 'QStuff*' (boreal) Winter'21 release season. All delivered in the two usual forms: - a pure stand-alone JACK client with JACK-session [5], NSM (Non/New Session Management [6]) and both JACK MIDI and ALSA MIDI [7] input support; - a LV2 instrument plug-in [8]. Changes for this release are just a few: - When under under the NSM auspices, fix SIGTERM handler on exit and just hide the main-window on close (applies to the JACK stand-alone only). - Fixed sample loop when the DCA EG is off or disabled (applies to samplv1 [2] only). The 'Vee One Suite' are free, open-source Linux Audio [10] software, distributed under the terms of the GNU General Public License (GPL) [11] version 2 or later.

KX Studio Carla - which version or how to install

by adam

I'm looking for clear install instructions for Carla, with its Win VST bridge. Tracktion Waveform comes with few instrumental sounds (only "Collective", I believe) so I hope to use KXStudio's Carla to enable the use of Win VST instruments. Waveform 11.1 on Ubuntu 18.04 64bit, my CPU is Intel i5. Here a demo of Carla running a Win VST or plugin, is quite persuasive, https://www.youtube.com/watch?v=PiaWozQ69eE On installing Carla on Ubuntu, one query and recommendation is here, https://askubuntu.com/questions/1035116/cannot-install-carla-on-ubuntu-18-04 KXStudio says first enable its repositories. So I've done that, https://kx.studio/Repositories Carla pre-compiled binaries and zipped source code to compile, are here, https://kx.studio/Applications:Carla Carla github install.md is here, perhaps this can make and install everything, https://github.com/falkTX/Carla/blob/master/INSTALL.md But here is what I don't understand, the 4 Carla variants listed; carla, carla-bridge-win, carla-git, carla-vst-wine https://kx.studio/Repositories:Applications Presently it looks like 'sudo apt install carla-git' is the 1st to try.
