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

Granting user access to alsa->jack plugin

by Julien Claassen

Hello everyone! There ave been countless threads - or shall I say threats? :-) - about this question of permissions, but I can't figure it out. I start my jackd as root. I have a user, which is in the group audio, perhaps that matters. I've had another look at limits.conf, but can't figure a good way to adapt it. I know, this somehow comes into it. I thought, I'd just store a .asoundrc for my user telling it to use the jack-plugin of ALSA. It doesn't work. If I run aplay -L or aply -l I only get the hardware card or some other pure and REAL alsa devices and null. So what is the point, that I'm missing? Any help on this is appreciated. I'm afraid, my system isn't set up by the distro, when it comes to audio. It's all self compiled and a lot of it has never been installed from packages. So no typical configs are there. I'm running a debian Squeeze, if that could help.

How to use? Calf Reverb DSSI control-in

by Jonathan E. Brickman

Anyone know what MIDI signals are acceptable to the Calf Reverb DSSI control-in port? All I need at the moment is bypass on/off, but how do I do this? I'd like to be able to send the MIDI signal both from a simple command-line applet and a programmable MIDI keyboard. -- Jonathan E.

AMS LV2 0.0.4

Hmmm, that's a weird one! My only explanation is that you have the file /usr/lib/pkgconfig/lv2-plugin.pc but not /usr/lib/pkgconfig/lv2-gui.pc... Could you check on your system? Btw, what distribution do you use? >From my side, I'm not even sure I need to check for both libraries in my wscript... As you said, they come from the same lv2-c++-tools package. Thanks for the feedback anyway :) Aurélien

AMS LV2 0.0.4

by Aurélien Leblond

Hello everyone, I just posted a new version of the AMS LV2 plugins: https://sourceforge.net/projects/avwlv2/files/latest/download The main change from the version 0.0.3 is a embeded GUI for the VCO. As a reminder, these LV2 plugins are a porting of the AMS internal modules designed to be used in a modular synths (especially Ingen). At the moment, the Analog Driver, normal and Advanced Envelop, Amp, LFO, Mixer, Noise2, Slew Limiter, VCA (Exponential and Linear), VCF and VCO2 have been ported. This should be enough to be able to create basic patches, and two presets for Ingen are available in the package. Testers, comments, feedback....everything is more than welcome! For the ones who wants to create LV2 plugins, the code is written in C++, using Lv2-C++-Tools and GTKMM (the GUI designed with Glade). The code is quite simple, making them examples on how to mix all these things together and be able to design LV2 plugins quickly... Aurélien

[absolutely OT, was: slightly OT] Musical citation (what is allowed?)

by Ralf Mardorf

http://www.consolesource.com/blog/wp-content/uploads/2008/01/rock-bank-xbox… (Subtitle for the blind: The picture shows pseudo-musical-instruments for a game console.) IMO everybody who makes music, on what level ever, is welcome. Fight dullness! Burn such game console trash! When I offered to teach children arts, my bosses wanted me not to do, but instead to teach them to keep order. Order is very important, and if everything is tidy, we can play pseudo-musical-instruments on Billy's game console. Have fun! "Musical citation" is the best way to learn, not especially to learn music, it will help you to learn anything. But we are living in a society of dullness. Reality scripting, participation shows, let's keep the folks stupid! And don't forget three times a day dusting your Ikea furnishings. Btw. Hartmut, you're right regarding to the GEMA. I could become much more off topic and write about my hard way, to get out of the GEZ. We are the borg, Ralf, aka eight of seven

a little web based ear training application

by Tony Austin

I found another web based ear trainer that also works with Linux: http://www.trainear.com/ It uses well known tunes to help fix the intervals in your mind.
