Hi, QMidiArp 0.5.2 has just seen the light of the day. It brings mainly two improvements. One is a comeback, that of tempo changes on the fly, and that now includes also tempo changes of a potential Jack Transport master. Also the Jack Transport starting position is finally taken into account, so that QMidiArp should be in sync also when starting the transport master not at zero. The second one is Non Session Manager support, mainly thanks to the work done by Roy Vegard Ovesen! Note that for compiling in NSM support you will now need liblo as dependency. Enjoy, and enjoy LAC in Graz this year Frank ________________________________ QMidiArp is an advanced MIDI arpeggiator, programmable step sequencer and LFO. Everything is on http://qmidiarp.sourceforge.net qmidiarp-0.5.2 (2013-05-09) New Features o Tempo changes are again possible while running, both manually or by a Jack Transport Master o Jack Transport position is now taken into account when starting, QMidiArp used to start always at zero o Muting and sequencer parameter changes can be deferred to pattern end using a new toolbutton o Modules in the Global Storage window have mute/defer buttons o Global Storage location switches can be set to affect only the pattern o Non Session Manager support with "switch" capability (thanks to Roy Vegard Ovesen) General Changes o NSM support requires liblo development headers (liblo-dev package)

itop

by elboulangero

Hello everyone, lately I had to fight big XRUN troubles, and thanks to this forum I finally solved that. This excellent thread saved me: http://linuxaudio.org/mailarchive/lau/2012/9/5/192706 On my long quest, I tried to see a little bit more what happened with the IRQs on my system. I searched for a kind of 'top' utility to monitor the interrupts, but the only apps I found were either deprecated, or missed some cool features. So, I ended up writing my own tool to monitor the file /proc/interrupts. It's available a this address: https://gitorious.org/elboulangero/itop As its name indicates, it behaves pretty much like top, but for interrupts. It's quite a simple thing, that I tried to enhance a bit with some cool features: + refresh period can be specified. + two display modes: display interrupts for every CPU, or only a sum of all CPU. + display every interrupt (sorted like /proc/interrupts), or only active interrupts (sorted by activity). + in case the number of interrupts changes during the execution of itop (due to a rmmod/modprobe), it's handled without any fuss. + command-line options are also available as hotkeys for convenience. + at last, the program display a summary on exit. The idea is that this summary could be copied/pasted in emails to help debugging. If anyone is interested, feel free to try and comment ! Cheers

Support for Steinberg UR22 (Yamaha USB chipset 0499:1509)?

by cullinan＠rocketmail.com

Hi, there! I just got a Steinberg UR22 USB<->Audio / MIDI interface for my semi-prof. DJ work. I am working on Linux (only), but wanted to give this new product a chance. Well, it's basically a nice device but with an Yamaha chipset in it which seem unfortunately not supported from the latest (3.7.9) linux kernel(s). My questions are: - How likely is it to get this device fully supported on linux? - What needs to be done to get this device fully supported? I am an electrical engineer and did some linux device driver development in the past on some DMA stuff, but I am quite new to linux audio. But I am willing to help somewhere... I could try to reverse-engineer the USB stuff on Windows with the usbmon/usbsnoop/libusb things... But if it's too much work, to get it working, I could also just decide to send it back to Steinberg and thank them for not supporting Linux with their products. The USB information I could get is: $ aplay -l doesn't list that device $ lsusb ... Bus 002 Device 016: ID 0499:1509 Yamaha Corp. ... (See the more comprehensive $ lsusb -v below...) Related USB devices are: 0499:1501 Yamaha 0499:1507 Yamaha THR10 0499:1509 Yamaha Steinberg UR22 (what I am talking about) 0499:150c Yamaha THR10C Related search resuls are: Getting a Steinberg CI1 USB audio interface to work http://ubuntuforums.org/showthread.php?t=1696336 Yamaha THR10 amp / USB2.0 audio interface http://linux-audio.4202.n7.nabble.com/Yamaha-THR10-amp-USB2-0-audio-interfa… Thank you, Clemens (different one as in last link) -----8<----- $ lsusb -v -d 0499:1509 Bus 002 Device 014: ID 0499:1509 Yamaha Corp.

Releasing source code is not enough, I think...

by Filipe Coelho

Hi there everyone, specially developers. I think we should stop assuming releasing source code is enough. [GNU/] Linux is getting more user friendly, and most users are not able to compile software, plus some distributions make it specially hard (debian, ubuntu, fedora, opensuse) by having the libs installed but not the headers. Releasing software on windows or mac, even open-source, *always* comes in a binary, and most users come from there. Now, I have a "toolchain" repository for ubuntu 10.04 with gcc4.8, python3+qt4 and a bunch of other useful stuff. I use this to get generic linux binaries that (from what I know) work everywhere. I can make a developer-oriented tutorial on how to use that, so that developers can provide linux binaries to its users. Would that be something useful to Linux Audio?

Release of new WORLD-based voice synthesizer

by Tobias Platen

Hello WORLD is a free software speech synthesizer on the basis of a Vocoder. It has been widely used as a backend for UTAU[1] but it should be also possible to use it as a backend for eSpeak and other accessibility and/or music applications such as the "Singing Computer"[2]. My modified version of WORLD uses the well known vorbis codec for compression. The world4espeak synthesizer is interface compatible to MBROLA, and can be used to synthesize both singing and speech in real time on a modern computer. It is hosted at gitorious.org [3]. Currently there are no voices yet, a manual how to create voices will be published soon.

Converting specimen banks to petri-foo

by Thomas Mayer

Hi, I have played around with petri-foo the first time, and I am thinking about switching from specimen to it. Is there a utility to convert specimen banks to petri-foo banks? As far as I can tell, it is a simple XML transformation, and I would try that, if such a utility does not exist. Thanks, Thomas -- "Ich komme aus dem Staunen nicht heraus."

But I find that a bit hard to believe... There's a difference on how KXStudio repositories are done vs regular debian/ubuntu repos. Debian and Ubuntu usually build against a specific version, and don't usually do backports. on KX repos I'm starting build all packages the same way (ie, the generic linux builds), and update software very often (sometimes minutes after release :D ). I hate when distros only package new stuff for the their newest, unreleased/testing/upcoming version and completely ignore the users running stable versions... :(
