I think this is because the mcu (port?) of ardour isn't connected to the BCF. But, qjackctl won't let me connect those. They don't show up in the MIDI tab of qjackctl. They only show up in the ALSA tab of qjackctl. >> > >> >> run a2jmidid -e > Right now MIDI Driver is set to "raw". I'm not sure when or if > I set that, or whether it might be the default. Try none.

MIDI keyboard not recognized

by jy

Hi all, I've recently installed ubuntustudio 12.04 and after trying it out, i discovered that my M-Audio Oxygen8 v2 MIDI USB (yes it is class compliant) keyboard is not recognised. It was recognised out of the box on my previous setup based on ubuntu 10.04. By not recognized, i mean that it doesn't appear in qjackctl connexions. thus i cant route the connexions correctly... Below are some logs ! How come it doesn't work any more ? How can i correct this ? Thanks a lot Cheers, jy ####LOGS#### $cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xf0400000 irq 45 $aplay -l carte 0: Intel [HDA Intel], périphérique 0: ALC888 Analog [ALC888 Analog] Sous-périphériques: 1/1 Sous-périphérique #0: subdevice #0 carte 0: Intel [HDA Intel], périphérique 1: ALC888 Digital [ALC888 Digital] Sous-périphériques: 1/1 Sous-périphérique #0: subdevice #0 carte 0: Intel [HDA Intel], périphérique 3: HDMI 0 [HDMI 0] Sous-périphériques: 1/1 Sous-périphérique #0: subdevice #0 $lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 002: ID 0bda:0158 Realtek Semiconductor Corp.

Re: [LAU] [ot] Data recovery

by Colin Fletcher

Julien, photorec (http://www.cgsecurity.org/wiki/PhotoRec) claims to be able to recover .wav files: it might be worth a try. Good luck! Colin. -----Original Message----- From: Julien Claassen Sent: 09/09/2012, 16:11 To: linux-audio-user Subject: [LAU] [ot] Data recovery Hello everyone! I'm sorry to post this here. I've just deleted two days worth of recording work by accident or lack of concentration. It has just happened. Any trick to get the files back. I think, nothing should have been written on the partition yet. It's mostly .wav-files, so I can't just grep the device file for the partition for some text. The computer has one more partition, but it's smaller, so methods, that require a full image of this partition are out. Thanks for any advise! and kind regards Julien ---------------------------------------- http://juliencoder.de/nama/music.html _______________________________________________ Linux-audio-user mailing list Linux-audio-user(a)lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-user

Featured Artist : #2

by Patrick Shirkey

Hi, The second selection in the new series called "Featured Artists" is up now at: http://linux-audio.com Featuring ##### Louigi Verona ##### ******************* Background info ******************* The idea behind the new "Featured Artists" section at the Linux Audio Users Guide is to provide a promotional vehicle for the artists in our vibrant community to showcase their work and to entertain and educate our audience at the same time. Think of it as an exhibition or installation where the "Art Gallery" is 450x800 pixels and the audience is people who are genuinely interested in Linux Audio and multimedia. If you are an artist and you would like to participate in this project we will assist with programming and planning to help you realise your vision. Please contact me directly if you would like to take part in this project. Cheers -- Patrick Shirkey Boost Hardware Ltd

matrix mixer?

by michael noble

I haven't come across anything before, but has anyone come across a matrix mixer, either in plugin or standalone form for Linux? Something similar to the matrix mixer objects in AudioMulch or the Acousmodule VSTs. I am aware of a couple of examples in PD, and googling brings up links to SuperCollider emails, but I would rather a more ready made approach if possible. thanks Michael

Praat problems - no more console usage?

by Julien Claassen

Hello everyone1 Is anyone here a little familiar with praat? Praat is supposed to run on the commandline, accepting its scripting languages. But when I ran praat just now - after years of no use -, I only get this: > praat - (praat:25242): Gtk-WARNING **: cannot open display: On the praat webstie, this method is still mentioned in the tutorial as acceptable. I'm running Debian Squeeze and Praat 5.1.42-1 from the Debian repository. Last time I started it must have beenunder Debian Lenny. Does anyone have any suggestion? all the libraries are correctly installed, or should be. I did work with GNOME a little on this release. Warm regards Julien ---------------------------------------- http://juliencoder.de/nama/music.html
