It appears that the first time the application is run there are some resources not yet setup, but when they are created the application does not load them right away. Run once, shut down, run again and all the translated text labels and menus are available. It does look like it could be interesting. -- Chris Caudle

[LAU] San Francisco contacts ?

by Dave Phillips

Greetings ! A student of mine is traveling and will be in the San Francisco area soon (within the next couple weeks). She'd like to see some musical sites, so of course I've recommended she check out CCRMA. Are there any other notable places or events - music stores, art museums, concerts - that she could check out while she's there ? Any and all recommendations appreciated ! She's a beginner in electronic music production, working mainly with a Grimes-like setup including Ableton Live, a nice Arturia controller, a few good VST synth plugins, and - best of all - an open mind and a receptive ear. Thanks in advance ! dp

[LAU] Installer Script for cm-incudine on Arch Linux-based Distros

by Brandon Hale

Hello all, Have you ever wanted to use cm-incudine, but felt like it was too hard or too much work to install on your Arch Linux-based distro? Now you can install it with https://github.com/brandflake11/install-cm-incudine <https://github.com/brandflake11/install-cm-incudine>. This script will take you from zero to hero, installing emacs, slime, quicklisp, and all of the dependencies needed for cm-incudine. Hopefully this helps you install cm-incudine if you've ever been interested, but couldn't figure out all of the smaller bits. Feedback is welcome! Thank you very much for your time, Brandon Hale

[LAU] Open Sound Control: Is it still a thing?

by worik

Vaguely Linux Audio related Is Open Sound Control still a thing? Was it ever? I am shopping for a mixer, I am a bit worried that the digital controls are a bit too propitiatory. I do not want to get orphaned by a firm going out of business and letting its iPad App rot. OSC looks like a solution, but it does not seem to be implemented by many vendors I am hoping that eventually the mixer will be controllable by the software I am building around a Raspberry Pi Worik -- If not me then who? If not now then when? If not here then where? So, here I stand, I can do no other root(a)worik.org 021-1680650, (03) 4821804 Aotearoa (New Zealand)

[LAU] Four channels playback?

by Rodolfo Medina

Hi everyone from a new one to this list. It is a sort of experiment. Suppose you have a multi channel audio file, i.e. composed by, say, three, or four different channels. Is it possibile (I guess it is), and how?, to send each of the four channels into a different loudspeaker and so listen to the song...? Do you think, e.g., the Behringer UMC404HD audio interface will allow to do that? Thanks in advance for any help, Rodolfo

[LAU] consolidating a firewire sound card with my other existing pci (alsa) soundcards

by Athanasios Silis

Hi all, I have recently acquired a Focusrite SaffireLE (analog: 4ins & 6 outs, firewire) and I am trying to figure out how can I consolidate its analog ins/outs with the rest of my setup: The same audio server hosts other soundcards that are happily driven by alsa. so JACK can see all the rest of the sound cards (through zita-a2j, etc). Now comes the firewire card. If I start a separate jackd session with the firewire backend jackd -R -n firejack -dfirewire then I get to see 6 ins and 8 outs (digital in/out included). I have 2 problems with this setup: - how do I connect the 2 jack sessions (with 0ms latency if possible). I tried with zita-n2j but with anything less than 100ms buffer the sound is unbearably choppy. - I tried to route some audio stream to each one of the outputs but from some outputs I could not get any sound, then routing to out1,2 would play from physical outs 3,4 - so not ideal. I tried to use the ffado-mixer to fiddle around with routing , but did not manage anything. Then I thought, to use the alsa driver , since alsa "sees" the card normally. $ cat /proc/asound/cards 6 [SaffireLE ]: BeBoB - SaffireLE Focusrite SaffireLE (id:2, rev:1), GUID 00130e010004184f at fw1.0, S400 but aplay only registeres a single PCM device: $ aplay -l card 6: SaffireLE [SaffireLE], device 0: BeBoB [SaffireLE PCM] Subdevices: 1/1 Subdevice #0: subdevice #0 so this is not ideal. IS there a way to get the alsa driver to identify all the ins and outs ? Alternatively, is there a better way to use a single jack session and load the 2nd backend as well ? (maybe through audioadapter or otherwise) Finally, is there a chance to coordinate 2 jack sessions (each with one of alsa, firewire backends) with 0 latency between them ? In this setup does anyone have experience with SaffireLE and how to control the mixer? Thank you!
