Hello et bonjour! :-) And this is the other outstanding release. this time I took more care regarding the links and I wasn't in such a trance. :-) I can only say: thanks to everyone, who has helped me create this album. There were a lot of people, including Joern, who designed the album art, which unfortunately won't appear anywhere but on the six copies of this CD. Yes, it was the first and only time, that I decided to make a fully fledged CD from that, with everything. and from inspiration, to recording, to proof-listening and reading, I got help from lots of very nice people, Both from this list and somewhere else in the world. this time the concept is much more evident, mostly in inspiration, but also in the titles, in some quoted music and production. So here we are with "Soit-il la Vie: Intense, Aimante": http://juliencoder.de/nama/soit_il_la_vie I had a fond time with it. I hope, you may also have a few nice minutes with it. - And that's the "back log" cleared. Warm regards Julien ---------------------------------------- http://juliencoder.de/nama/music.html

[LAU] sndfile-waveform direct display?

by Peter P.

Just discovered Robin's wonderful sndfile-waveform program- what a nice addition to the Linux Audio toolchain! i was wondering if there i a way to make it display images directly, perhaps piping its output to "display" or other programs? best, Peter

[LAU] Envy24Control is missing the Analog Volume tab - need guidance...

by Cullen Davis

I need help troubleshooting a recording issue on a dedicated audio computer with a single DSP2000 C-Port. I can not record from the analog inputs of my audio interface. I suspect that it is because the analog volume tab on the envy24control mixer is missing which means that I can not raise (or activate) the ADC sliders. 1) Should the analog tab exist for an ICE1712 device (dsp24 with an ADC&DAC2000)? 2) If yes - can anyone help me troubleshoot why the tab is not there? 3) Can anybody confirm if the DSP2000's channel LEDs should light up? (They do light up when using the OEM drivers on an XP partition of the computer) A lot of solutions to this problem are “on the envy24control analog tab, make sure the sliders have been moved up". Without that tab, I can not see if this is a solution to of my recording woes.... Hardware / Software The hardware is a MSI 915 (intel p4) mb with all on-board devices turned off in bios (except for graphics). The only card on the motherboard is a dsp24 pci card connected to an external 8 channel ADC&DAC2000 box. (aka DSP2000 - http://www.st-audio.de/products/dsp2000/info.html). For the OS, I am running Fedora 17 with PulseAudio removed and a realtime kernel (3.4.11-1.rt19.2.fc17.ccrma.i686.rtPAE) installed. The pci hardware is found, the ICE1712 mods load, and alsa reports the card as device 0 (the only device). The card does work when booted to an XP partition on the machine. Driver versions are: alsa-lib-1.0.26-1.fc17.i686 alsa-tools-1.0.26.1-1.fc17.i686 jack-audio-connection-kit-1.9.8-9.fc17.i686 The jack subsystem is working fine for synthesized audio and playback of existing files. My USB control services are passing through jack just fine. My problem is that I can not get the analog inputs on the DSP2000 to activate. I am absolutely sure that I am sending a signal to the input box - but no combination of settings on the alsamixer or the envy24control seem to be effective in activating the input channels or recording the signal. To record, I am running a Shure SM58 into a PreSonas Bluetube preamp and running the unbalanced out into the DSP2000 input 1 (I have tried all eight) of the DSP2000. When the same signal is run into a standalone mixer - the meter shows a hot signal. The DSP2000 has two preamps - I can get the clip indicator on the DSP2000 to trigger if I push the signal too hot. That tells me that I am getting a signal to the breakout box’s input. I would appreciate any help or troubleshooting tips anyone could provide. CjD

[LAU] Does somebody use a RME HDSPe AIO?

by Ralf Mardorf

Does somebody use a RME HDSPe AIO with ADAT? If so, is Linux working with all 8 channels? I bought one in Mai 2011, but didn't need all channels until today. Analog IOs and ADAT 1 and 2 are ok. HDSP mixer does see incoming audio signals from all ADAT ports, so I thought everything is ok, unfortunately it isn't, the jackd ports for ADAT 3,4,5,6,7 and 8 don't work. Tested with Ubuntu Studio Precise and Quantal 64-bit (hdspmixer 1.11) and AV Linux 32-bit (hdspmixer 1.6). At the moment I need some additional channels :(. I don't think the card is broken, because HDSP mixer does show the incoming audio signals, but you never know. Since it has got a 3 year duration of cover I should check this immediately, but I don't know how to test it. Do I need to install Windows to test the card? Regards, Ralf

[LAU] List of working MIDI devices?

by Thijs van severen

Hi all Last week my brother got his new digital drum. its an octapad clone (only cheaper) that fits our needs perfectly. Before we decided to get this model i googled to see if it is linux compatible, but couldnt find anything. Now that we have it i can confirm that it works :) However, i was wondering if there is a page/wiki/list where i could add this info so others can see this? Grtz Thijs

[LAU] Laborejo 0.4 release

by Nils Gey

A wild crosspost appears! Laborejo, Esperanto for "Workshop", is used to craft music through notation. It is a Lilypond GUI frontend, a MIDI creator and finally a tool collection to inspire and help you compose. It works by reducing music-redundancy and by seperating layout and data. Before you read the details make sure to connect to Laborejos Facebook, Twitter or Google Plus! https://www.facebook.com/Laborejo https://twitter.com/#!/Laborejo https://plus.google.com/b/116744898976321238325/ Screenshot: http://www.laborejo.org/images/screenshots/latestscreenshot.png This is the release of version 0.4 Download: https://github.com/nilsgey/Laborejo/tarball/0.4 Dependencies: http://www.laborejo.org/documentation Linux Instructions: Unpack, cd into the created directoy, execute: ./laborejo-qt Then use the number- and cursor keys for immediate success! Check Help->Manual for navigational and note/rest entry keys. Everything else is in the menus. New since version 0.3 (highlights): * Lyrics are visible under the tracks directly and aligned to their notes * Nicer cursor :) * New dynamics like fp and sfz. * New commandset for note speed entry with the numblock. * Colored always-visible Marker in the GUI to indicate track groups. Also displays small instrument name for better orientation * Lilypond binary and pdf viewer are now a config variable * More Subsitutions (assign a pre-defined group to host notes. Group gets transposed and scaled accordingly). Final Fantasy arpeggio, common melody figures etc. * Many bugfixes and small improvements that make the program work like you expected it to do anyway Most important known problems: * This is Alpha Grade Software. Don't use for long-term work. However, the produced midis and PDFs will last forever. * There is no built-in jack midi output yet. You have to export midi files. * Documentation is nearly non-existent. * Deleting selected objects may result in strange gui behaviour. Nothing a save/reload can't fix for now. Have fun, it would be nice to hear from you! Nils http://www.laborejo.org

[LAU] OT: New i7 rig, Gfx card recomendations and more.

by Kaza Kore

Hi all. A little of your expertise and experience would be appreciated here. I am aiming to build a new computer to go in my old rack-mounted case, which has basically been out of service since I got my laptop some years ago. The main parts I have chosen based on what are used in some of the Ubuntu based video servers here at work. But they run in an X-less environment (using Firefox Chromless interface, controlled remotely via http from any (generally Windows) computer on the network) and use Blackmagic cards for HD video ingest and playout. Most likely I will be hoping to get a stable Fedora/CCRMA install working on this computer (something I'm sorry to say I have attempted a few times on the laptop and failed.) I do suspect I will be persuaded to install Win7 on it at some point though. Why, you ask? Because it is due to be used with a mobile sound system for a combination of digital DJing, some VJing and probably some audio recording too. Although I will try and persuade people to use Mixxx (or use their own laptop) too many people are more used to, and have their controllers configured for, Tracktor or Serato. Of course it depends on it being commercially viable for me buying a licence for one of these and for basic, vinyl controlled digital DJing I believe Mixxx is now sufficient (although yet to test their claims.) On the VJing side the argument seems just as strong, with there being nothing to even remotely challenge Resolume out there! Somebody please correct me if I'm wrong. (And also a good place to discuss Linux (Live) Video. I joined the sister list to this one on the subject but don't think I'm yet to see a single email on it.) But as I said I want to try and go the Linux (and predominantly FOSS) route at first. I start with the few questions on the chosen pieces first: Motherboard I am looking at is the Asus P8Z68-V Pro/Gen3. As this is going to be very mobile I want to use the RAID option of the card. I was thinking 3x WD Caviar Black 1TB drives, connected to SATA 3Gb/s ports using RAID5 (cheaper than 2x 2TB drives and same redundancy.) I believe this is on the Z68 chipset. Does this kind of RAID play well with Linux? I would want multiple partitions across this main space so OS(s) and data both have redundancy. Specs for the video servers used here are i7 2600k but I see the 2700k is only a few quid more so assume the upgrade would make sense? I currently have a RME RPM (useful due the the dual Phono input meaning no prestage is needed for vinyl control of DJ software.) I only have the HDSP card for the laptop though. Would you recommend the PCIe or standard PCI HSDP card for use on Linux? At some point I would quite like to also get a Multiface for recording multiple streams at once but that is probably some time away and if I can get it all working with the RPM I'm sure it will with the Multiface. Graphics card recommendations??? As stated some VJing work so will need something reasonable but I don't think it needs to be up with what is needed for the latest games. Budget is flexible-ish... I've already extended it once ;-) Although maybe I should scale it back a little and go for a cheaper motherboard and i5 processor of some kind? At this specification it would seem silly not to use it as my main rig! Sorry for going on and on so much. Many thanks to all that have managed to read and digest everything I have written. I have a backlog of posts from this list I will read through now, before getting to any replies I hope to receive from you ;-) TL/DR: Z68 - works with RAID5 on SATA2 ports OK? RME HDSP card - PCI or PCIe? Gfx card recommendations?? Or persuade me to go for a cheaper rig as I probably don't really need all that... Regards, Dale.

[LAU] New release of jmeters

by Fons Adriaensen

Hello all, Jmeters-0.4.1 is now available at the usual place: <http://kokkinizita.linuxaudio.org/linuxaudio/downloads/index.html> Jmeters is a Jack app offering software versions of various traditional analog audio level meters. This release is a major update. It offers VU meters, BBC, EBU and DIN style PPM meters, stereo versions (using red and green 'needles') of the three PPMs, and correlation meters matching the VU, BBC and DIN styles, most of them in different sizes and shapes. The Jmeters instruments have the correct 'ballistics' for both the VU and the PPMs. Given the same input, they will indicate exactly as the original electro-mechanical meters, all of which are rather strictly specified in various standards documents. New features: * DIN style peak program meter (IEC type I). * Stereo correlation meters. * The default 'style' is now a rectangular frame of around 300 by 170 pixels. There is also a smaller rectangular form, and the two original round 'Meterbridge' styles are still available for all types except the DIN style PPM. * The meter 'needles' are now plotted using the Cairo library which provides much better visual quality than the raw X11 graphics used previously. * It is now possible to put labels on the meters, just include them on the command line, either mixed with the Jack port names or after them. Anything not containing a ':' is considered to be a label instead of a Jack port name. Many thanks to Richard Lamont for all comments and suggestions. Enjoy ! -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
