[ANN] Radium Compressor V0.5.0

by Kjetil Matheussen

Radium Compressor is the system compressor in Radium, but distributed as a standalone jack application. Radium Compressor uses the stereo compressor found in effect.lib in the Faust distribution. This compressor is written by Julius O. Smith III. It has been optimized by using fast approximate logarithmic and exponential functions written by Paul Mineiro. The GUI accurately shows the sound used for compression, and how much, and how, the sound is compressed. I haven't seen this in any audio compressor GUI before, but it's probably been done before. Demonstration video: http://www.youtube.com/watch?v=KphCxloBq2w Tar-ball: http://archive.notam02.no/arkiv/src/?C=M;O=D Source repository: https://github.com/kmatheussen/radium_compressor Changelog 0.0.1 -> 0.5.0: * Don't autoconnect jack ports by default * Option to set jack client name * Faster graphics * Graphics uses less CPU * Support for ratios between 0 and 1

avw.lv2 0.1.2: Here they are!

by Aurélien Leblond

Hello everyone, I just released today a new version of the avw.lv2 plugins. As a reminder, this project started as a porting of the Alsa Modular Synth internal modules to LV2 plugins: VCO, LFO, VCF, etc... Teamed up with Ingen, they can be used to create modular synths or analog drum machines (but the list is not exhaustive!). But in the latest versions, the suite saw the addition of a few other plugins not coming from AMS: - a (very basic) DownSampler that can be used as a filter to degrade the sound - a Granulator which is a granular effect for real time audio - interesting for VCOs, but as well for vocals, guitars or even drums - a Beat Repeater and a Beat Slicer: the Beat Repeater would repeat a certain number of beats, where the Beat Slicer would repeat randomly beats in a bar - again I find them pretty interesting for drums and guitars They can be downloaded here: http://sourceforge.net/projects/avwlv2/files/avw.lv2-0.1.2.tar.gz/download SVN: svn checkout svn://svn.code.sf.net/p/avwlv2/code/trunk avw.lv2 GIT: git clone https://github.com/blablack/avw.lv2.git For Ubuntu users, a PPA is available: https://launchpad.net/~blablack/+archive/music-prod Finally, although I have been tested these plugins extensively and wrote them to be easy and straight forward to use, please please please provide any ideas, feedbacks, bug reports, anything to improve them! Hope you enjoy them! Aurélien

A manuscript submitted for review cannot be already under review for publication elsewhere, or be submitted for a second review elsewhere while under review for NIME 2013. Call for Performances We welcome submission of proposals for performances. Proposed performances should have a clear connection with the substance of the NIME conference. Performance proposals in conjunction with paper submissions are encouraged, but each will be judged on its own merit. Within reasonable limits, we may be able to provide musicians to perform pieces. Typical NIME performance pieces last for 5-15 minutes, but shorter and longer performance proposals may also be taken into consideration. Submitted proposals will be reviewed by an expert committee. Preference will be given to submissions with strong evidence that the proposed performance has already been realized or is technically feasible and within the artists' capabilities. Documentation of the performances will be available online after the conference. Call for Installations NIME 2013 will also provide several locations that can be used to exhibit new music installation work. These are foyer location installations or room-based installations in connection to the conference venues. Submitted proposals will be subject to a peer review process by an international expert committee. Documentation of the installations will be available online after the conference. Call for Workshops We call for short (3 hours) or long (6 hours) workshops and tutorials. These can be targeted towards specialist techniques, platforms, hardware, software or pedagogical topics for the advancement of fellow NIME-ers and people with experience related to the topic. They can also be targeted towards visitors to the NIME community, novices/newbies, interested student participants, people from other fields, and members of the public getting to know the potential of NIME. Tutorial proposers should clearly indicate the audience and assumed knowledge of their intended participants to help us market to the appropriate audience. Workshops and tutorials can relate to, but are not limited to, the topics of the conference. This is a good opportunity to explore a specialized interest or interdisciplinary topic in depth with greater time for discourse, debate, and collaboration. For any further information, please contact Woon Yeo (woony(a)kaist.edu). ---------- Woon Seung Yeo Assistant Professor Audio & Interactive Media (AIM) Lab Graduate School of Culture Technology, KAIST http://aimlab.kaist.ac.kr woony(a)kaist.edu | woony(a)ccrma.stanford.edu

lv2-mdaPiano v0.0.1

by rekado rekado

Hi all, I ported the mda Piano VSTi by Paul Kellett to the LV2 specs. The LV2 plugin has been tested in jalv. You can download the first working version here[1]. The original used a hard-coded C array to store sampled values; in this version the array has been replaced with a raw audio file. It should hence be possible to replace the sound material that the plugin operates on with some higher quality samples. The raw audio file can be played back with: aplay -t raw -f S16_LE -r 44100 data/samples.raw Contributions / bug reports are welcome. -- rekado ______ [1]: https://github.com/rekado/lv2-mdaPiano/archive/v0.0.1.tar.gz

PHASEX-0.14.97

by William Weston

Announcing PHASEX-0.14.97 !!! [P]hase [H]armonic [A]dvanced [S]ynthesis [EX]periment The new version of PHASEX is shaping up quite nicely. For those of you who missed the announcement of v0.14.96 on linux-audio-dev, here's a recap of what's new since v0.12.0: New Features: - Multitimbral (1 thread per part). - Session bank (very much like the patch bank). - Jack Session. - Stereo- and Multi- outputs for JACK. - ALSA PCM audio. - JACK MIDI. - ALSA Raw MIDI. - Generic MIDI (/dev/midi support). - MIDI clock for timestamping and queuing events. - Active Sensing. - New oscillator waveforms. - Portamento for Osc Transpose events. - FM oscillator latching. - New LFO parameters. - Moog (24db/octave) filter. - Fast fade-out mono retriggering. - Interpolated oscillator table lookups. - Ability to run with no GUI. - JACK MIDI / ALSA Raw / ALSA Seq connections in menus. - Widescreen layout mode. - New preferences dialog w/ nearly all settings. - New knobs. - Pure 64-bit math in builds with --enable-cpu-power=4. New Features from Anton Kormakov: - LASH. - MIDI Hold pedal. - JACK Transport. Bugs Removed and/or Squashed: - The "bad PHASEX noise" is gone. - GUI widget sensitivity is fixed. - Notebook tabs behave properly (and quickly). - Patch loading bugs are gone. - MIDI program change works dependably. - Spurious envelope triggering pops are gone. - Offsets for neg. filter env. now calculated properly. - Chopped portamento slides are fixed. - Keytriggering for all keymodes is fixed. - Voice stealing works as expected. - Chorus phase balance issues have been corrected. - System lockup on shutdown is a thing of the past. - Denormals don't eat up all the CPU anymore. Code Overhaul: - Build system overhaul. - Reorganization of source code. - Rebuilt data structures for multimbral architecture. - New driver layer (engine relies on no libraries). - Replaced pthreads based buffer synchronization code. - New lightweight patch parser / patch format. - New thread-safe MIDI event queue. - Restructured engine, GUI, and MIDI code. - Almost complete separation of GUI and engine. (still need to separate bank changes from the GUI.) ChangLog for v0.14.96 --> v0.14.97: * Cleaned up pointer sign warning in queue_midi_event(). * Included (/usr)/bin/true configure.ac fix from Jörn Nettingsmeier. * Included falktx's build patch for src/Makefile.am. * Added synth-part to MIDI channel assignments to midimaps. * Removed unused type_id from struct jack_port_info. * Added proper detection and conditions for new JACK features. * Reworked BPM handling and removed duplicated code. * Fixed typo in pixmaps/Makefile.am. (Adam Sampson) * Implemented note-off instant release from attack and decay. * Implemented round-robin voice assignment for mono-multikey. * Fixed bug with assigning MIDI CC in GUI. * Changed MIDI CC mapping event (now ctrl-middle-click). * Changed depracated AM_CONFIG_HEADER to AC_CONFIG_HEADERS. * Fixed FTBFS on systems w/o CLOCK_MONOTONIC_RAW. (Adrian Knoth) * Fixed crash and clock sync issues with changing jack buffer size. * Consolidated gtkknob frame offset calculations. * Added checks to prevent errors on JACK client close. * Fixed usage of JACK stereo/multi menuitems for monotimbral builds. * Fixed potential LASH client name bug when using ALSA MIDI. * Added JACK latency recalculation when changing buffer_latency. * Added git version tag tracking to build system. * Changed default locale to "C" instead using env defaults. * Fixed settings not saved on quit. * Fixed new dirs/files not created bug in phasex-convert-patch. * Fixed GUI param update race condition on updated flag. * Fixed sporadic GUI param sensitivity update issue. * Updated system synth-patches. Thank you everyone who contributed build fixes for v0.14.96. Out of the box, v0.14.97 should build cleanly on any recent Fedora, CentOS, Debian, Ubuntu, ArchLinux, Puppy, or Mint distribution. Please report any build failures immediately! NOTE: The patch file format has changed, so any old patches (or patch directories) will need to be converted with the phasex-convert-patch script (included). Any old (pre- v0.14.x) patches found in ~/.phasex/user-patches will be converted to new v0.14.97 patches in ~/.phasex/patches automatically. Patches in other directories will need to be converted manually. Please take this as an opportunity to sit down and familiarize yourself with the new features and cleaner sound. (If you actually do prefer a more aliased sound, you can always configure your build with --enable-cpu-power=1...) Overall, I am pleased with where PHASEX has arrived. In the past, I had always been disappointed with PHASEX and its shortcomings, and for many reasons. Until now. The code is cleaner and easier to work on. Most of the old bugs have been replaced with more intelligent design. On an -rt kernel, xruns are a thing of the past. Sound quality is cleaner. GUI is much more responsive. Starting from the command line is only necessary for running without the GUI. Sessions can be managed with ease. Per part memory and CPU utilization has decreased vs. multi-instance v0.12.x. Timing is almost as good as it gets (sample accurate for JACK MIDI, near sample accurate for ALSA seq, and almost as good as your hardware will allow for ALSA raw MIDI.) Most of the major barriers to use that have been identified over the years have been eliminated. Many thanks go out to Anton Kormakov for his work on PHASEX and his git repo, which appear to have served the community well in the time since the old server went down. And of course, I'd like to thank the regular posters to linux-audio-dev and linux-rt-users for sharing the knowledge that's made this release possible. PHASEX-v0.14.97 is currently availiable in source code form only. (Binaries will be available starting with v0.14.99.) Sources are available via git: git clone https://github.com/williamweston/phasex.git Number of synth parts is configurable at compile time. For live / on-stage use, please limit to 1 part per CPU core and test your polyphony limit ahead of time. For songwriting / studio settings, 1-2 parts per CPU core is recommended. (Tested extensively with 8 parts on a quad-core q6600.) As usual, YMMV. Please refer to INSTALL and README for more details. Enjoy the new PHASEX. This release aims to be as bug-free as possible (and IMHO, v0.14.97 is already more stable and trouble-free than any previous version). As is usual with GPL'ed software, there's no warranty whatsoever and I'm not responsible if you blow out your speakers (or your hearing), but please don't let that hold you back from trying it out. Let's make some music! Cheers, --William Weston

Re: [LAA] Contemplative Practices Conference -- call for art/demos/installations

by Ivica Ico Bukvic

Small clarification. The deadline is posted on the submissions page (http://www.cpe.vt.edu/cpts/submissions.html), namely: Proposal Submission Opens - Monday, December 17, 2012 Proposal Submission Deadline - Monday, February 11, 2013 Authors Notified of Proposal Acceptance - Friday, March 1, 2013 For additional info please see: www.cpe.vt.edu/cpts/ Finally, we are not anticipating programming any concerts but we may have a "listening room." For your convenience, below is also a summary description that may help answer some of the commonly asked questions: ICAT's IMPACT Studio invites proposals for art, installations, and technology demonstrations with focus on contemplative practice. All submissions will be reviewed by an interdisciplinary panel consisting of ICAT faculty. Selected projects will be showcased as part of the ICAT Open House and on display throughout the conference. Where appropriate, some submissions may be also presented in a paper and/or poster format as part of the "Technology" track. Authors of selected submissions will be expected to attend the conference. We seek any art, installations, and technology demos with focus on contemplative practice. While proposed art and installations should also leverage technology, within the context of this submission we define technology in the broadest terms possible. Please provide as much information as possible, including space and technology support requirements, to help us determine the best venue for your work. While limited funding may be available to help offset the cost of shipping the equipment, applicants for the ICAT Art, Installations, and Technology Demos track should assume that all unique exhibit/demo-specific equipment and supporting hardware will have to be shipped at presenter's expense. Best wishes, -- Ivica Ico Bukvic, D.M.A. Composition, Music Technology Director, DISIS Interactive Sound & Intermedia Studio Director, L2Ork Linux Laptop Orchestra Head, ICAT IMPACT Studio Virginia Tech Dept. of Music - 0240 Blacksburg, VA 24061 (540) 231-6139 (540) 231-5034 (fax) ico(a)vt.edu http://disis.music.vt.edu http://l2ork.music.vt.edu
