Music recorded with Linux: c2015-19a

by jonetsu＠teksavvy.com

Greetings, This piece is a longer one that develops a bit slowly. I made up a tag for this: AcousticWaveRock. The instruments are acoustic guitar and acoustic bass guitar, to which a few synths sounds were added as well as drums and percussion, sampled from a Korg Microstation JazzBrush Kit. What's new in this project, as I progressively learn, is the use of what is called 'multing' tracks, eg. taking bits of a track and copying/moving them to another track. This was used to move some guitar parts to another track where a delay, for instance, was applied. It could have been done with automation although using another track is simpler IMHO, especially when a different EQ is chosen. No automation curves to make. Also got recently a headphone amp (Behringer HA400) that's connected to jack's 3 and 4 playback outputs (1 and 2 still remain connected to the M-Audio studiophone speakers), the audio card being a 1010LT. It is now possible to listen in stereo ! Previously the headphone jack from the M-Audio speakers was used, and it did not give much of a stereo effect. The switch from one set of playback device to another is done using Ardour's monitor output choices. Also, there's the use now of two mics for each of the acoustic instruments, each mic recording to its own track. There's an AT2020 in omni mode, no cut, and a M-Audio Pulsar (not Pulsar II). This piece 'goes forward' in the sense that themes only occurs once. When they occur they are repeated, but they do not come back later. The supporting structure stays the same though. Cheers. https://soundcloud.com/nominal6/c2015-19a

multitrack export midi type 0 (gramophone2) issue

by Benoît Rouits

Hello, I have written generative composition with a chomsky grammar parsed by and *old* program called gramophone2. Unfortunately, my tests composition have multitrack but gramophone2 generates midi type 0 files (1 merged track). So, all midi sequencers i tried does only import track #1 while there are 3 or 4 in the midi file with different speeds (i'm playing with yet another phasing music). It may be a grammophone2 bug, but before to dive into the code (if i find it) how could i convert the generated midi type 0 into a type 1 so that tracks speeds can be aligned ? With the hope the question is well asked and not out of topic. - Benoît

Re: [LAU] Updated to kernel 4.4.1, missing module snd_ice1712 -> no more envy24 support?

But thank you for initially pointing me to the bug-report where my "inappropriate" comments got this bug correctly resolved. Furthermore, hopefully this means people updating to 16.04LTS in the near future will still have use of their Envy24 sound cards.

Jconvolver example files and jconvolver packages

by Ralf Mardorf

Hi, after an off-list correspondence with Hermann, I noticed something, that might explain the difficulties those new to jconvolver have got. [rocketmouse@archlinux ~]$ pacman -Ql jconvolver jconvolver /usr/ jconvolver /usr/bin/ jconvolver /usr/bin/fconvolver jconvolver /usr/bin/jconvolver jconvolver /usr/bin/makemulti "Ralf_Mardorf commented on 2016-02-20 16:22 Hi, as it turns out by two LAU thread http://lists.linuxaudio.org/pipermail/linux-audio-user/2016-February/104030… http://lists.linuxaudio.org/pipermail/linux-audio-user/2016-February/104075… some users experienced difficulties using jconvolver. I couldn't understand why, since I've got examples how to do this, but then I noticed that the AUR package doesn't install the examples from the tarball. Consider to add those examples. Regards, Ralf" - https://aur.archlinux.org/packages/jconvolver/#news This might be an issue for other distro's packages too. Regards, Ralf

Fwd: Re: Is there a GUI for convolver?

Hermann Meyer <brummer-(a)web.de> schrieb: What you talk about is so called multi file support, and thru, that isn't implemented, but, that didn't mean it is not stereo. Just use a stereo IR file, and you have stereo reverb. Note, that the marity of Reverb files comes as Stereo files. Jc-gui may be usefull to get some working config files for jconv, they could give you a Hint how to wrote them, and you could start with edit them, to create your own, with multi file support, when you need it. -- Diese Nachricht wurde von meinem Android Mobiltelefon mit WEB.DE Mail gesendet.

It's _not_ really stereo, since there seems to be no way to use a left.wav and a right.wav. So assumed you like to use jconvolver as reverb, it will not sound that fantastic, as it sounds when writing a config with an text editor. _____________________________________________ Linux-audio-user mailing list Linux-audio-user(a)lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-user

Ardour session with plain ALSA, without JACK

by Ralf Mardorf

Hi, if I chose "Audio System: JACK" I can start a new session, but if I chose "Audio System: ALSA", I get "Failed to open audio device". Perhaps I make a mistake. There's no special reason that I want to use ALSA instead of JACK, I just want to test it. I never tried to do it before, with any other version of Ardour. $ pacman -Q ardour ardour 4.7-1 $ grep jack /var/cache/aur/current/ardour-4.7-1-PKGBUILD --with-backends="jack,alsa" \ --libjack=weak \ $ amidi -l;aplay -l;arecord -l Dir Device Name IO hw:0,0 HDSPMx579bcc MIDI 1 **** List of PLAYBACK Hardware Devices **** card 0: HDSPMx579bcc [RME AIO_579bcc], device 0: RME AIO [RME AIO] Subdevices: 1/1 Subdevice #0: subdevice #0 **** List of CAPTURE Hardware Devices **** card 0: HDSPMx579bcc [RME AIO_579bcc], device 0: RME AIO [RME AIO] Subdevices: 1/1 Subdevice #0: subdevice #0 Regards, Ralf

Looking for speakers and demonstrations for the "Open Source Audio Meeting Cologne" (monthly community meeting)

by Nils Gey

Dear developers and users, the "Open Source Audio Meeting Cologne" takes places monthly since June 2014 in Cologne, Germany. It is a community meeting: linux and open source audio enthusiasts, user, musicians and developers connect, share, discuss and help each other. But the meeting is also a monthly "mini linux audio conference". While not really a formal conference we have talks and demonstrations each time that deal with musical, technical or scientific aspects of everything music and audio with free and open source software and hardware. Regular attendance is close to 10 people for regular meetings and more for special meetings, for example when we have invited speakers and "guest-stars". I would like any of you to be such an invited star. If you are in the area (or willing to make a trip) it would be fantastic to have you here and give us a talk or demonstration about YOUR topic. Be it your music, your software or anything that you work with or on. You can answer me in private or publicly, your choice. If you are interested here is some more condensed information: -The time frame for a talk or demo is from 30 minutes to 2 hours for such an event. -Dates for 2016 (all Wednesdays, all 7pm): March 16th, April 20th, Mai 18th, June 15th, July 20th, August 17th, September 21st, October 19th, November 16th -The language can be English or German -The place is Heliostrasse 6a, 50825 Cologne Germany and has very good public transportation nearby and is therefore easy to get to. -While we have no money to offer you can get a place to sleep for the night and food. -We provide the option to record your talk on video and upload it (or simply send it to you, if you prefer) Website: http://cologne.linuxaudio.org It would be fantastic to hear from you! Yours, Nils Gey

soundcloud social environment

by jonetsu＠teksavvy.com

I do not know much about soundcloud. I know how to upload and I used to know how to enable download of files (I'll have to recheck what Set and/or others have written here about this :) For instance, I do not know the context much. How people scan for files, how people try to sell stuff like services or such (I have the impression that some attention a file may gather has nothing to do with the music). So on my latest upload someone has put a picture/comment on the track, to the effect that 'this is a nice picture where I would like to be'. When NOT logged into the account I clicked on this to see what it is about then I clicked on the picture itself. At that point Konqueror froze completely and the desktop went a bit jerky. So I killed -9 konqueror. I did not pursue any investigation as to why it happened. Just to let you know. It might turn out that everyone knows much more about soundcloud than I do and are aware of possible mishaps. Cheers.

Ardour: use case for monitor plug-in ?

by jonetsu＠teksavvy.com

Hello, In learning more about Ardour, recording and mixing in general... Ardour has recently added the capability for the monitor to also have plugins just like any regular track. What would be use cases for wanting to have a different audio specific to the monitor ? Cheers.
