New Website and Music

by Gerald

Hi folks, I would like to announce the new website of my Band Jimson Drift (www.jimson-drift.de). For now its in German, but I think the word 'Songs' is clear enough ;) Just 3 Songs there, but are more to come, for e.g some of these older ones: www.jamendo.com/en/list/a62900/groove-venture, with the new Band Members . It's lovely here in Karlsruhe at LAC2014 and I'm happy to meet some of the key devs of linux audio, thanks for your efforts and check the Dank& Links section of the website. Regards, Gerald

AVLinux in KVM?

by Ken Restivo

I was going to play around with some studio stuff, don't have a system set up for that any more, so figured I'd try running a linux audio distro in a VM. UbuntuStudio runs fine. But the latest release of AVLinux refuses to boot, it says: > No DEFAULT or UI configuration directive found! > boot: _ Googling around shows that I need to rename isolinux to syslinux in order to fix this. However, the file system for the image is ISOFS, and there does not appear to be a way to mount it read-write in order to change it. Is there any other trick/workaround for this? Thanks. -ken

[ANN] OpenMusic 6.8.1 - fresh build from latest sources

by anders.vinjar＠bek.no

Hi all. I'll be running now to catch the flight to Frankfurt/Karlsruhe. Just uploaded a freshly built OM (still beta) based on recent changes in the sources. Look here: http://repmus.ircam.fr/openmusic/linux The build is available as .rpm and .tar.bz2. This one changes to portmidi for midi playback. All midi-handling (files, messages, events) is shared between all 3 supported platforms, presumably making code more general and sustainable. This also means you'll need a (32-bit) version of libportmidi.so installed (but no longer need libfluidsynth.so). Im looking very much forward to come to the LAC (1st time for me). Hoping to meet many of you there! Cheers, -anders

[New music made with Linux]: Prophetic jazz

by F. Silvain

Hey hey, Prophetic jazz is a jazz impro played purely on a hardware hybrid analogue/digital syntheszier, later on only processed by an IR reverb. I leave it to you to guess the synth. :) http://freeshell.de/~silvain/audio/prophetic_jazz.ogg or check it on the MicroLabel interface: http://www.freeshell.de/~silvain/microlabel The soundbank for the synthesizer is also available for download as a SysEx dump: http://www.freeshell.de/~silvain/p12_fs_bank.zip Ta-ta ---- Ffanci * Internet: http://freeshell.de/~silvain

Using recording equipment in Karlsruhe

by Egor Sanin

Hi folks! For everyone here in Karlsruhe at LAC2014, good to see you all! I was wondering if someone would be kind enough to allow me to use some medium-awesome to full-awesome recording equipment for a short recording session during the next few days. I didn't bring my gear over and have a short fit of inspiration that I would like to capture. All I need is a decent audio interface and a stereo pair of mics (I would settle for a single mic, too). Please respond off-list if you can help me out. Thanks!

HW upgrade - new computer

by Len Ovens

I have finally upgraded my music computer. I started with an older P4 with 2.5G memory. It was working well and able to get good latency (sub ms by qjackctl at 48000) but didn't have the guts to do much with it :) it had a single core. New MB: asus z87-k CPU: intel i5 at 3.2G I could have gotten an i7, but same speed/cores plus hyperthreading. Hyperthreading is anti low latency. so the i5 gives the same performance with less power use. Memory: 8G, all one stick, which is slower than two 4G sticks... maybe not the best choice, but seems ok. Video: on board, dual monitors - VGA plus DVI both 1600x900 Disk: 2TB sata about 5 years old (as I recall) Audio interface: Delta 66 Midi interface: ensoniq pci audio card. I chose this MB because it had three pci slots as well as 4 pcie slots which allowed me to keep using my old audio interfaces while giving me possibilities for upgrades. ASUS was nice enough to list the irq layout of the pci(e) slots in the user guide. All three PCI slots are shared with something else :P However, one is shared with a single channel PCIe slot - good! That PCIe slot will not be used. That is where the delta 66 went. One is shared with three PCIe slots and "IGD" (graphics?)... skip that one. The last is shared with the SATA controller and that is where the ensoniq went. The internal audio has its own irq (of course) but that is turned off in bios (as useless). The USB setup uses 3 irqs (two for USB2 and one for USB3) and so may do well with USB audio... if I had anything other than a USB1.1 audio device to try ;) I also turned the speed "Boost" off in bios as it can not be controlled by the OS. So far things look very good. With almost no changes at all and 3.13.0-24-lowlatency #46-Ubuntu for kernel (fresh ubuntustudio 64bit 14.04 install. I can run the D66 at 16 frames with very few xruns and all are spurious. Just to be sure the ensoniq was not interfering I modified the rtirq order to: "rtc snd_ice1712 snd usb i8042" This did make some small difference. Next, I turned cpufreq from ondemand to userspace so I could play with different speeds. I set cpu0 to max (3.2G) and assumed the others would follow all being on the same chip. I was wrong and the other cores were actually at 800 Mhz (were ondemand had left them). All of my xruns vanished. Ondemand sucks. I obviously wasn't pushing this too hard (it would have been too hard on the old P4). I was running jack at 16 frames (2 periods) with the pulse to jack bridge running at the same time playing a video full screen too. Qjackctl said the DSP load was less than 10% so I will have to find some way of loading it up some more. Things to try (to load the system): - mostly MIDI stuff. - keyboard in - some HW synths I have around here - soft synths... lots of them at once. - IDJC with: - live mic - skype through pulse to idjc - some mp3 or ogg files playing (at least two at once) - maybe mumble at the same time too or more than one skype. I will monitor the cpu temperature with different user set CPU speeds. So far I am very happy with what I have seen. PCI is certainly not dead, though it is getting harder to find. I could not find any Xeon boards with PCI slots for example... even if I had wanted to pay the extra. qjackctl gets loaded at session start and is setup to start jack and a2jmidid when it runs. Pulse starts then too. Pulse is set up to have all audio interfaces turned off so that jacksink/source is always default. For all the bad things I have heard about pulseaudio... it just works. -- Len Ovens www.ovenwerks.net
