Hi all,
For a sound playback system I'm putting together, based on a Raspberry Pi 3,
I'm looking to have 4 channels of input and output, and to have the system
to run automatically at startup.
For this, I'm wondering how to (best) execute zita-a2j and zita-j2a; I've
tried two methods that don't work:
1. ask Qjackctl to execute the following script after startup:
sleep 5
zita-j2a -d hw:CODEC_1
2. execute this script:
qjackctl (with auto-start)
sleep 10
zita-j2a -d hw:CODEC_1
Executing the zita-j2a manually after Qjackctl has finished starting the
jack server does work.
Any pointers greatly appreciated!
Cheers, Steven

Anyone have any comments about Muse 3.1?
muse-sequencer.org is down right now, but their github is up...
I've been on 2.1 as my main sequencer for ages.

Hello!
I'm setting up a remote server now to run generative audio ideally routed via JACK to liquidsoap and out to a web radio stream.
The server is a physical machine colocated in a datacenter but I'm not sure if I will be able to install an audio card into it -- it would be easiest if I didn't have to.
Does anyone know if there a way to run jack for routing internal audio without an actual audio card?
I'm also interested in using jacktrip on the server.
Thank you!
Best,
Erik
jalv.select is a little gtkmm GUI to select lv2 <http://lv2plug.in/>
plugs from a list and run them with jalv
<https://drobilla.net/software/jalv/>.
Project :
https://github.com/brummer10/jalv_select
Features:
* select jalv interpreter from combo box,
* select LV2 plugin from list,
* select preset to load from menu
* search plugins by regex or plugin class,
* reload lilv world to catch new installed plugins or presets,
* load plugin with selected preset.
* minimize app to systray (global Hotkey SHIFT+ESCAPE)
* wake up app from systray (global Hotkey SHIFT+ESCAPE)
* left mouse click on systray to show or hide app
* right mouse click to show quit menu item
changelog in this release:
* add support for a user made blacklist.

Dear list,
I am compiling a list of suitable sound cards for a mobile real-time
experimental setup. There are some criteria that such a sound card should
fulfil:
- External sound card: We have a mini PC with an on-board sound chip. We
want to use an external sound card with a decent sound quality. Our mini PC
has USB-2, USB-3, USB-C (Thunderbolt 3) connections.
- Class compliance: We have a real-time signal processing platform, the
Master Hearing Aid, which runs on Linux (Actually it also supports Windows
and Mac, but we prefer Linux). Therefore we need a sound card, which Linux
can operate. Manufacturers usually do not officially support Linux, but
there are some, which run on Linux, because they are class compliant and do
not require a dedicated driver.
- At least 4 (preferably 6) analog (identical) inputs and at least 2 analog
(identical) outputs
- Lower sampling rates: As we will do real-time signal processing, we
prefer lower sampling rates for the sake of computational complexity.
Therefore, ideally we would like to have a sound card, which supports even
16kHz, but 32kHz also OK.
I know that these criteria are not easy to fulfil. So far, I couldn't find
any sound card, which fulfils all the requirements. In the worst case, we
can sacrifice the last requirement and downsample our sound input before
processing, but it is a good-to-have one.
We would appreciate any suggestion. Thank you in advance.
Best Regards,
Kamil Adiloglu
