Hi! Yesterday I finalised the international counting track and submitted low-quality versions (1 MB size limit) to the Ubuntu Free Culture Showcase. https://wiki.ubuntu.com/UbuntuFreeCultureShowcase I made 2 versions, with and without whistling. The speech melodies inspired me, but the whistling might be found to take away from the counting. Several formats and the complete Ardour session are available from http://www.archive.org/details/countint Wavpacking the source audio-files would have saved about 40 MB, but I decided that it wouldn't be worth the trouble on the receiving side :) Big thanks to all the contributors: Sampo Savolainen, Finnish, http://sampo.garageflower.net becks, Italian, http://msound.org Robin Gareus, German, http://gareus.org Ken Restivo, US-English, http://restivo.org David Paez, Spanish Gordon JC Pearce MM3YEQ, English, Gaelic, http://www.nekosynth.co.uk Savvas Z.

clicks in sound when running dual core

by Robert Jonsson

Hi folks, Been reinstalling my studio computer these last few weeks. Moving to 64 bit and dual core.. or so I thought. As it turns out I have found that my system is unable to run jack reliably while using dual core. I use MusE as sequencer and it's especially evident there but I believe I have noticed it with other applications. The thing that happens is that I get random clicks in both input and output. If I start the computer and add maxcpus=1 to the kernel line all seems ok. Thinking back I realize that I stumbled on this problem on the last rebuild some years ago but ended up running single core without investigating why this was. I thought I would at least throw this out here now, google seems to know nothing about this issue. Anyone else have experienced anything similar or is my hardware faulty? (AMD64X2 based) Regards, Robert

FST status update

by torbenh＠gmx.de

hi... small status update. the race conditions related to lash and gui drawing should be fixed now. vst window takes keyboard grab most of the time, so keypresses are working. i am mucking around with reactor now, but i cant get it to update its GUI. Martin Profittlich contributed load/save which got integrated now. MidiLearn is only saved via lash. ok... so give it a test please, i think i am going to make a realease after this weekend. -- torben Hohn http://galan.sourceforge.net -- The graphical Audio language

In search of a new laptop for audio - Firewire with Power-Out needed.

I could be wrong, but I always thought that the full size firewire plugs were powered and the smaller ones were not.

In search of a new laptop for audio - Firewire with Power-Out needed.

by Nils Gey

Hi list, I try not to start some flamewar. Normally I can look up my hardware alone, but all the hardware-websites can't help me in one point: I need a laptop which is able to power my Firewire-Interface (Terratec Phase X24) over Firewire. Do you know if something like this exists? All my laptops in the past (2) were not able to do that. Both had only a "small" firewire-interface. Nils

Success! An Asus EEE softsynth!

by Ken Restivo

I'm happy to report that I am writing this from my new EEE softsynth, running an RT-patched kernel, jackd, and several softsynths. System info, if anyone is interested, is here: http://restivo.org/projects/eee I'm stunned that this even works, but it does, and astoundingly well! I've got cpufreq userspace governor, manually set to maximum CPU speed (1.6Ghz). I'm using the crappy built-in hda-intel card, and not even at its native frame rate (I'm at 44100, not 48000). I'm also using a version of jackd that has been reported to be sub-optimal (0.109.2-3). The last missing peices were the rt2860sta and atl1e drivers, which I built in a few minutes from source packages already in Debian-EEE (make-kpkg modules_image .... done!). Many thanks for the patch to fix the alsa_seq; it works perfectly in the 2.6.26.8-rt12 kernel. I now have a usable Linux synth for live performance, which weighs 1.45KG, fits in a backpack, runs all my crucial sounds, draws about 1 amp at maximum CPU speed, and reportedly will run 6 hours on its own internal battery. With the cheap Edirol PCR-30 I bought a few months ago, and a small battery-powered amp, I can do street performances now-- or other casual gigs-- while lugging a minimum amount of gear. I'm thrilled. I still have to compile a couple packages that aren't in Debian: my own few utilitiies, AZR3-JACK, klick, WhySynth, and a few others, and I'm set to go. I also want to recompile the kernel again to change the timer 1000Hz not 250Hz. 0.109 works, but what is the most stable/reliable/efficient version of JACK I should look into. 0.116? -ken

Request for open source solution to spectrograms and phase measurement

by Ismael Valladolid Torres

Sorry for the crossposting, but I don't know which list is more suitable to what I'm asking. One friend of mine is looking for a solution based in Linux. I admit I don't understand fully what he needs. That's why I am asking to you gurus out there... :) He needs something for level measurement of spectrograms, callibrated as K-14, also for phase measurement. He used [1]a plug-in for Nuendo in the past, but now he's looking for a netbook devoted only to this task, and he wants to use an open source solution. 1. http://www.nugenaudio.com/visualizer.php Any suggestions welcome.
