Some music made with linux, from the vaults

by Ken Restivo

Found these cleaning an old hard drive, all made with Linux, Fluidsynth, Ardour, PHASEX, JACKRACK, seq24, jace, and probably others. Techno-ish and featuring PHASEX heavily: http://storage.restivo.org/music/krmusic/semipublished/breakfast-at-one-0.1… Funky in 9/4 and with enough shifting patterns that the 1 is pretty much arbitrary (the way I like it), and also using PHASEX in the background: http://storage.restivo.org/music/krmusic/semipublished/allure-oddmeter-0.1.… These are both from August 2007, according to the git history. Enjoy. -ken

[New music]: Days of Borrowed Time

by Julien Claassen

Hello everyone! Here is the serious piece of electronic music. Rather more depressive than I would have predicted. First though I have to express my gratitude to Alison Utter for the sweet vocals, that she has supplied. Thanks! And then we have the links: http://juliencoder.de/nama/borrowed_time.ogg http://juliencoder.de/nama/borrowed_time.mp3 And the lyrics: http://juliencoder.de/nama/borrowed_time.html Or you can access it all from the music page: http://juliencoder.de/nama/music.html Now about that song: technically speaking I used a lot of Midish and Nama. And for the first time I really came to appreciate Ecasound's LV2-support. So also a big thanks to Jeremy Salwen, who contributed that feature! Musically, this is a mixture of different influences. I'm still not sure, if it should be categorised as pop or electronica. there's some dubstep in this, as well as some hiphop - in German! :-) - and some basic depressive pop. As to instruments used: almost everything I have at my disposal. In software I only used LinuxSampler for the Solina sample. Thanks to the friend, who made a present of it to me! It's a versatile instrument! This latest experiment concluded, I will just lean back and relax. As ever: feedback is very welcome! Warm regards and enjoy Julien ---------------------------------------- http://juliencoder.de/nama/music.html

Community Interaction and Working Together

by Harry van Haaren

Hello all Users & Devs of linux-audio-land, Moving forward from the topic on Aeolus and forking projects, perhaps it is wise to look at how the community as a whole can grow from this situation: 1) It seems the frustration of forks is mainly due to lack of communication. 2) Had appropriate communication been in place, patches could have been merged. 3) If 1) and 2), then the community flourishes as a whole. In the Aeolus thread on LAD, Michel Dominique wrote (and I feel its relevant here): "That imply we must communicate more with each other" "I think this is a big problem, and not only related to Fons work, or the LAD, but to the whole community." The mailing list you're reading from now is one of the central hubs for the community: The -developers list is the perfect place to announce projects, forks, patches etc. The -users list is good for asking users and interested parties questions. I will try to announce more patches / code, to contribute upstream, and hopefully benefit the community. Cheers, -Harry

Synchronization of audio with MIDI file

by Angel de Vicente

Hi all, this weekend I need to do some synchronization work, and I was planning to use Qtractor (though I've never used it before), but I thought I might ask here, in case you think there are better tools to accomplish this. My setting is very simple: I have a two guitars piece and I have recorded one of the parts myself. For the second guitar I have entered the score with Rosegarden. But now I want to fine-tune the mixing of both and I want to be able to synchronize the MIDI file to my playing. With Rosegarden and the piano roll, I can easily stretch/move each of the MIDI notes, but I didn't find an easy way to synchronize with my audio wave (though I haven't used Rosegarden a lot, so perhaps I missed something). Ideally I would like to: + load in one program both the audio and the MIDI file + see the soundwave forms for both audio and MIDI plus the piano roll for the MIDI file + if something is not synchronized properly (due to the nature of the music, I can see it nicely by inspectint the soundwave), I would like to stretch/move the MIDI notes in the piano roll and interactively see how the soundwave changes, so that I can immediately see if the MIDI and the audio are better synchronized. Is there a tool where I can do that easily? Perhaps there is some other procedure/tool that can help me with this? Thanks for any suggestion, -- Ángel de Vicente http://www.iac.es/galeria/angelv/ --------------------------------------------------------------------------------------------- ADVERTENCIA: Sobre la privacidad y cumplimiento de la Ley de Protecci�n de Datos, acceda a http://www.iac.es/disclaimer.php WARNING: For more information on privacy and fulfilment of the Law concerning the Protection of Data, consult http://www.iac.es/disclaimer.php?lang=en

Jack does not see USB sound card Boss Micro BR-80

by Erik Steffl

trying to use Boss Micro BR-80 as USB soundcard with Jack but seems like jack (qjackctl) does not recognize it. My system: Ubuntu 13.04 with pretty much standard configuration (runs pulseaudio, installed jackd2, pulseaudio-module-jack, qjackctl) Have built in audio that I don't really plan to use with jack (or at least not in initial setup where I am just trying to make something work): 00:01.1 Audio device: Advanced Micro Devices [AMD] nee ATI Wrestler HDMI Audio [Radeon HD 6250/6310] 00:14.2 Audio device: Advanced Micro Devices [AMD] nee ATI SBx00 Azalia (Intel HDA) (rev 40) Boss Micro BR-80 seems to be recognized properly (see below) but qjackctl does not list it in Set under any of Interface, Input Device, Output Device choices, I only see /dev/dsp, /dev/audio, plughw:0 and hw:0. Any ideas why it does not work or how to troubleshoot it further? When I plug BR-80 in I get (output of usb-devices): T: Bus=08 Lev=01 Prnt=01 Port=01 Cnt=02 Dev#= 3 Spd=480 MxCh= 0 D: Ver= 2.00 Cls=ff(vend.)

noise with pulseaudio on Delta 66

by Paul Coccoli

I've had a Delta 66 PCI audio card for over a decade, and it's always sounded great. I recently had to transfer it to a new PC with a fresh install of Fedora 17. Now, when I play anything using any pulseaudio client, I get a strange digital noise (sort of like static, but almost like aliasing too). This does NOT happen when running jack, as far as I can tell. Aside from disabling or uninstalling pulseaudio, is there anything else I can do? Does anyone else have this problem?

Launchpad S and Linux

by Aurélien Leblond

Hi all, I'm thinking of getting the Launchpad S and I was wondering if anybody had any go at them with our favourite operating system: - the Novation website says the S version of the Launchpad doesn't need a driver ans is therfore compatible with Linux. Is it simply seen as a MIDI device? - Would Hydrogen or SooperLooper be compatible with it? I know it might be a stupid question if it is a midi device, I'm just curious how it would interact with the tools we have. - It might be a misconception on my part, but from the videos available online it looks like software can control the device to change colors of the pads... I would be curious to know if say SooperLooper can control the Launchpad a light up the corresponding pad if the loop is muted or not Thanks for any information you guys and girls might have, I'd really love to be able to use it!

by Rui Nuno Capela

yet again, a new batch the Vee One Suite of old-school software instruments is out: synthv1 [1] polyphonic synthesizer, samplv1 [2] polyphonic sampler and drumkv1 [3] drum-kit sampler. as usual, all three are made available in dual form: - a pure stand-alone JACK client with JACK-session, NSM (Non Session management) and both JACK MIDI and ALSA MIDI input support; - a LV2 instrument plugin. as for this release changes: - First attempt on separating the DSP code from UI as runtime objects, effective for the LV2 plugin deploy. - MIDI channel filter switch is now introduced. - Fixed uninstall target make rule. - Mono(phonic) mode switch is now being introduced. - Another minor fix to note-off fast-release. all free and open-source Linux Audio software, distributed under the terms of the GNU General Public License (GPL) version 2 or later. so, here they go again: [1] synthv1 - an old-school polyphonic synthesizer synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.
