The first unified LV2 release, LV2 1.0.0, is out. This release merges the previous lv2core package with all the official extension packages, as well as example plugins, lv2specgen, and additional data. From a developer point of view, the biggest change is that all LV2 API headers can be used by simply checking for the single pkg-config package "lv2" (for compatibility the previous "lv2core" package is still installed). Implementations are encouraged to abandon the "copy paste headers" practice and depend on this package instead. With this release, several new extensions have become stable that together greatly increase the power of LV2: atom, log, parameters, patch, port-groups, port-props, resize-port, state, time, worker.

QMidiArp-0.5.2 released

by Frank Kober

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)

Yoshimi V 1.2.3

by Will Godfrey

Up on sourceforge now. It's faster: Has better compatibility with Zyn: Has some usability enhancements: Introduces 'naturalising', a small, configurable, per part random pitch shift: Kudos to Mark and Paul for an interesting optimisation to Zyn in AddSynth. At the last minute I heard of a bug in ALSA MIDI where trying to auto connect resulted in Yoshi bailing out, so from this version onward until I can sort it out the feature is disabled. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

[ANN] xjadeo 0.8.0

by Robin Gareus

Xjadeo is a video player that displays a video-clip in synchronized to an external time source (MTC, LTC, JACK-transport). http://xjadeo.sf.net/ -=- Greetings Soundtrack Designers and fellow Multimedia Artists, Xjadeo version 0.8.0 just came out and brings a lot of significant changes. Most notably: * openGL display * video-frame indexing * built-in UI / context menu With openGL, video-scaling is now performed in hardware and playback synchronized to the screen's vertical refresh (if the hardware permits that; most graphics cards do). This is the new default display and supersedes prior platform-specific video outputs (XVideo, X11/imlib2, SDL, quartz, which are still available via the --vo option and also used a fallback). Video files are now scanned and indexed on load which provides for reliable seeking to video frames for a wide variety of codecs where frame-accurate seeking was not possible with earlier versions of xjadeo. This also acts as a guard to detect and refuse broken video files early on. User interaction has been overhauled, most notably by adding a menu that facilitates discovering key-bindings. This deprecates the external control application qjadeo which previously came with xjadeo. There have been over 200 changes since the last release, the complete changelog is available at https://github.com/x42/xjadeo Other highlights include: * separate On-Screen-Display for Sync-Source and Video Timecode * self-documenting OSC API * disable screensaver * 64 bit timeline * new website Note that various command line options have changed. The seek-related -K, -k parameters are no longer needed due to the change to indexing. Letterbox is enabled by default, and it is now also possible to start xjadeo without an initial file. In short, a lot of defaults have been updated to make xjadeo more topical (despite that fact the the menu for the X11 variant is plain old toolkit-less Xlib :) Statically linked binaries are available for GNU/Linux, OSX and Windows from http://xjadeo.sourceforge.net/download.html as is the source code in terms of the GPLv2. xjadeo is developed and has been tested for accuracy with ffmpeg-2.2.5 it may or may not work properly with different versions, but compiles with any version of ffmpeg >= 1.0 to date. Many thanks to Chris Goddard who provided valuable feedback and spent several weeks on quality assurance and polishing user interaction. We're far from done on the quest to 1.0, yet 0.8.0 marks a major milestone in the life of xjadeo. Cheers! robin

Re: [LAA] [LAU] [LAD] hrec

Hi Silvain Thanks for trying it out! On 8/21/14, F. Silvain <silvain(a)freeshell.de> wrote: > Hey egor, > thanks for the new tool.

Yeah at the moment I can only confirm that hrec works when run with Python2 explicitly. As I mentioned I had problems running it with Python3. As far as I know, the pyeca python module, which I use as a bridge between hrec and ecasound, doesn't play well with Python3. Try installing hrec with python2 explicitly, on Arch Linux it would be like this: $ python2 setup.py install

[LAD] hrec

by Egor Sanin

Hi folks, I've been working on and off for the last little while on a command line recording utility. It's really basic and the code is pretty ugly. It exists partly because in my lazy search I couldn't find anything that satisfied my particular need, and also because it was interesting. I just made a first release, so you could try it if you like. The program is called hrec, it's basically a curses front end to a very limited subset of ecasound's functions. Code is here: https://sourceforge.net/projects/hrec/ AUR package is here: https://aur.archlinux.org/packages/hrec/ I'm planning to do change it soon, but the basics will remain the same. Mostly I plan to remove the playback functionality, as it's almost useless -- plenty of other software to do it much better. Also I need to migrate the code to Python 3, but I'm getting stuck on the python ecasound bindings. In the couple of (admittedly not very thorough) attemps I've made I ran into problems with the current pyeca module. Any advice would be appreciated. Anyway I thought I might as well release it now and get some feedback. I hope someone finds hrec useful! Criticism and insults are also welcome. Thanks!
