This device is working with Kernel 3.1 (in debian wheezy). 1. Check dmesg if the device is registered. You should get something like this: [ 400.908425] usb 3-1: new full speed USB device using ohci_hcd and address 2 [ 401.129862] usb 3-1: New USB device found, idVendor=0a73, idProduct=0010 [ 401.129873] usb 3-1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 401.129879] usb 3-1: Product: Onyx Blackjack [ 401.129882] usb 3-1: Manufacturer: Loud Technologies Inc. [ 401.130118] usb 3-1: configuration #1 chosen from 1 choice maybe you get some of these, too: [79005.602627] 5:1:1: cannot get freq at ep 0x1 [79005.615632] 5:2:1: cannot get freq at ep 0x82 [79007.303653] 5:1:1: cannot get freq at ep 0x1 [79007.322655] 5:2:1: cannot get freq at ep 0x82 They are no problem! 2. Go to System Settiings (KDE Control Center) click on Multimedia (German version): Choose Audio output (Dont know the exact english descriptor) and choose the Onyx Blackjack device. Maybe you have to create the following file (dont know exactly if this has an effect, but its what I did and the device works now I guess this ones for alsa): /etc/asound.conf with the following content: options snd-usb-audio index=0 options snd-aoa index=1 you will have to change snd.aoa to the driver of your onboard soundcard. snd- aoa is the Apple Powerbook onboard soundcard. Maybe you will have to install apt-get install phonon-backend-xine 3. To use it in audacity with jackd: - Simply start qjackctl, in Preferences (Einstellungen in german) switch input device (eingangsgerät) and output device (ausgangsgerät) to Blackjack -> USB audio, maybe you wish to deselect 'force 16bit' (16bit erzwingen) to record in 24bit and turn the sample rate to 48khz Sometimes jackd doesnt start properly, then simply start it again and make sure you plugged in the blackjack first (and enabled phantom power, if necessary). - start audacity and switch its soundsystem to jack audio and start recording! So I think you can consider the mackie onyx blackjack working in linux (debian wheezy at least. but it should be working in a recent ubuntu with a 3.1 kernel, too). The devices' sound is really great, especially the preamps. Have fun drz

[slightly OT] Musical citation (what is allowed?)

by Julien Claassen

Hello everyone! I'd like to cite from a relatively recent work (1970), which of course is still copyrighted. So can I do it per se? I'd just like to cite a main phrase for a bit (2-4 bars) I suspect. any hints on that would be very much appreciated.

LinuxSampler and expression pedal

by Julien Claassen

Greetings LAUers! Has anyone of you experience with LinuxSampler and expression pedals (for controlling volume)? I have never owned one, butI'm thinking of buying one. I think all my synths are set to their respective standards, which I suppose should be OK as such. Do I need to re-route MIDI controller data (change the CC number) to get it to change the volume? Sorry, if that is a stupid question, I have the feeling, it's rather obvious.

Fwd: Re: The pain of Firewire audio hardware

by thijs van severen

Looks like i replied to Alexandre only iso the ML :-S My 2 cents below : ---------- Forwarded message ---------- From: "thijs van severen" <thijsvanseveren(a)gmail.com> Date: 29 Nov 2011 22:22 Subject: Re: [LAU] The pain of Firewire audio hardware To: "Alexandre Prokoudine" <alexandre.prokoudine(a)gmail.com> in the mean time the numbers have gone up (see http://www.ffado.org/?q=usage/bydevice) but Alexandre is right. quite often you hear linux users blaming the 'big bad' companies for boycotting linux. i work for a big company and it's quite simple. if there is no market the product will not be developed. it's a simple calculation. if those companies would be able to make more money by dumping MS and switching to android (or linux in general, but it looks like android is about the only 'linux variant' that is doing things right in terms of marketing, usability etc > boy, am i going to get my ass kicked for writing this! ;-) they would do so. simple. no $$, no product. for a company like focusrite (i just pick focusrite because i own a saffire LE, the same goes for some other companies) donating 1 device is not costing them anything. IMHO they are doing this for 2 reasons : first, there are a couple of people at focurite that are linux lovers and they pull some strings to have focusrite donate some units to the FFADO guys. Second, focusrite might be curious to see what happens "you never know what the next big market change might be". But one thing is for sure : they are NOT donating a device because they see it as a market opportunity that will increase sales. but like i said, this is just MHO 2011/11/29 Alexandre Prokoudine <alexandre.prokoudine(a)gmail.com> > > On Tue, Nov 29, 2011 at 8:06 ... -- follow me on my Audio & Linux blog <http://audio-and-linux.blogspot.com/> !

Keystroke or MIDI-controlled reverb/flange/etc. filter capability?

by Jonathan E. Brickman

Greetings. I have a need to turn on/off multiple software audio filters (reverb, flange, chorus, et al.) using either computer keystrokes or MIDI control signals. Anyone have a way? I've looked at GUI automation of calfjackhost instances and several other things, but have not found anything likely to work very well. -- Jonathan E.

Re: [LAU] Keystroke or MIDI-controlled reverb/flange/etc. filter capability?

by thijs van severen

Is there no option for you to switch this fx chain on/off by creating some sort of bypass in your audio path? It might be easier to control just this 1 'switch' via midi iso all of your fx at once.

[ANN] Jass-0.9 - Jack Simple Sampler

by Florian Paul Schmidt

Hi, I spent a few hours here and there to work on jass. Thus I give you release 0.9 which is fairly feature complete. But it might still have a gazillion of bugs. So please test, before I go 1.0.. http://shirkhan.dyndns.org/~tapas/Jass-0.9.tar.bz2 Jass - A Jack Simple Sampler Qt4-, libsamplerate-, libsndfile-, jack_midi-, jack_session-, ladish-L1-enabled sampler.. Changes (AFAICT): * graphical editors for most parameters (those can be resized to suite your needs) * waveform display to set sample start/end, loop start/end * keyboard widget to set note, min note and max note * a retarded dial_widget that is barely usable :D * global voice allocation (you can set the global polyphony per setup in the xml file * ADSR envelope that actually works * show/hide some parameter sections Screenshot (showing all parameter editors): http://i.imgur.com/Ssc4F.png Regards, Flo

The pain of Firewire audio hardware

by Lorenzo Sutton

[Long, partly rant-ish, pouring OT email, so if you want feel free to skip] This morning I got the most polite, kind email from a person who knows me as "the linux guy" and saw me use linux with audio a lot, candidly asking "I need your help: were can I get drivers for my RME Fireface 400" for Ubunto? Now, I went writing the usual leitmotiv of explaining the situation with Firewire hardware on linux, the fact that most audio hardware makers suck at linux, the great FFADO effort, etc. etc. What will he think? I don't know. But, while writing I couldn't keep back a bitter frustration feeling thinking of having to explain this over and over. I'm not trying to find 'someone' to blame or anything, simply it feels frustrating, evangelising linux, showing it how great it is for audio, but then... there you go a simple polite question and this bitter feeling you can't really help him much... Arrrghh. And I wouldn't feel like saying thow it away and get a fully supported FFADO one, right? So. I wonder if we should do a audio-hardware-manufacturers push effort. I once wrote a (probably solitary, naive) email to RME who (rudely) replied that "ALSA does the drivers for linux, ask them" (WTF??). Maybe we could pick the 5 most popular yet lieux-unfriendly manufacturers and do a collective petition, lobbying, PR action. I'm no low-level dirver programming expert, but my feeling is that in some cases doing a binary version of their drivers wouldn't be so much effort. I know, I know... I said the "B" word (binary), but that's yet another debate. Having "something" for linux IMHO would be good starters. Sorry for the long pouring out, but this is one topic which I'm really sensitive to especially when relating to the "Macs are for serious audio" universe. (Arrrrggghh) Lorenzo. -- ** NOTE **: This gmail address is my new email. I will still be reading my libero.it email, but please use this new one for any further email. Thanks you for understanding. ** NOTA **: Questo indirizzo gmail è la mia nuova email. Continuerò a leggere la posta libero.it ancora per un po' ma vi prego di usare questa nuova da ora in poi. Grazie per la comprensione.

Building kernel headers 3.0.x-rt fails

by Ralf Mardorf

Hi :) is there a known issue for building kernel-headers (regular rt, no manipulation to get the proprietary Nvidia driver installed) 3.0.7-rt20 and 3.0.9-rt25 by running "make-kpkg --rootcmd fakeroot --initrd kernel-image kernel-headers" with Debian testing? At least in June building kernel-headers for 2.6.39.1 (not rt, just threadirqs) still worked. $ uname -a Linux debian 2.6.39.1 #1 SMP PREEMPT Tue Jun 7 01:40:05 CEST 2011 x86_64 GNU/Linux Right now I'm doing another trial to build the headers. If there should still be any messages, I'll post them later. Regards, Ralf

Since it's night, here's a lullaby :-)

by Julien Claassen

Evenin' all! this is very simple. It's the Goldberg variation no.7 slightly swinged andplayed on a rhodes. http://juliencoder.de/nama/lullaby.ogg Or for the ogg-ily impaired: http://juliencoder.de/nama/lullaby.mp3 Or access it through the website: http://juliencoder.de/nama/music.html Oh and it's actually called "Singing In Lullabies, Vowing In Adoration". I know, it might get a little repetitive. :-) Shouldn't be many more of them, then I'll think of something new. :-) I hope you might find it nice.It was done in the spur of the moment, just because I felt like it. Any comments welcome. Goodnight and sleep well :-) Uncle Julek =-=-=-=-=-=-=-=-=-=-=-=- Such Is Life: Very Intensely Adorable; Free And Jubilating Amazement Revels, Dancing On - FLOWERS! ====== Find my music at ====== http://juliencoder.de/nama/music.html .....................................
