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

[LAA] 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.

[LAA] gst123-0.3.1

by Stefan Westerfeld

gst123-0.3.2 has been released. Overview of changes in gst123-0.3.2: ------------------------------------ * Support building with gstreamer 1.0 or gstreamer 0.10 (Issue 11). * Added "-a pulse" PulseAudio output support. * Fix time display updates (broken by introduction of quiet mode). * Properly quit player if none of the files in the playlist can be played. * Cleanup code to avoid compiler warnings. What is gst123? --------------- The program gst123 is designed to be a more flexible command line player in the spirit of ogg123 and mpg123, based on gstreamer. It plays all file formats gstreamer understands, so if you have a music collection which contains different file formats, like flac, ogg and mp3, you can use gst123 to play all your music files. Since gst123-0.1.0 support for watching videos has been added; however gst123 should run fine in situations where no X11 display is available; videos can be played without X11 display, too (-x, --novideo); in this case, only the audio stream will be played. It is implemented in C++ and licensed under the GNU LGPL version 2 Links: ------ Website: http://space.twc.de/~stefan/gst123.php Download: http://space.twc.de/~stefan/gst123/gst123-0.3.2.tar.bz2 -- Stefan Westerfeld, Hamburg/Germany, http://space.twc.de/~stefan

[LAA] Wiimidi 0.7

by Roland Mas

Hello, After a certain amount of feedback and related improvement, I'm happy to announce version 0.7 of Wiimidi, a gateway for turning a Wiimote, possibly with an attached accessory/controller, into a source of MIDI events. New features in this version include: - syntax in the configuration file to send Control Change messages; - handle button release as well as button press; - full support for the guitar controller: frets, touch-frets, strum bar, buttons, whammy bar; - full support for the “classic controller”: buttons, sticks, and the analog triggers (which are buttons on the “classic controller pro”); - completed support for the nunchuck (directional stick). The code has also been vastly refactored, which should allow for easy support of additional controllers if someone feels like implementing a wah-wah pedal or a theremin with their wii balance board for instance. Also, the documentation is now much more complete :-) For more information, the documentation and the pointers to the actual code, see the Wimidi page at: http://roland.entierement.nu/pages/wiimidi.html Roland. -- Roland Mas Seems to me, the only sensible thing is for people to know if they kill a whale, they've got a dead whale. -- Adam, in Good Omens (T.

[LAA] First release of Wiimidi

by Roland Mas

I'm both pleased and surprised to announce the first real public release of Wiimidi, which I've arbitrarily numbered 0.5. Wiimidi is a gateway for turning a Wiimote, possibly with an attached accessory such as a Guitar Hero drumkit, into a source of MIDI events. While that's far from original, I seem to have gained a very excited user who encouraged me to actually make the program more visible (hence this email) and to add features, to the point that now it may be useful beyond just my own personal use case. The aforementioned user apparently used it with a hacked Wiimote as a pedal board during a jam session, and reports that it all went fine (hence his excitement) The “interesting” features that may or may not differenciate Wiimidi from other similar projects: - customisable mapping of the Wiimote buttons (and drumkit pads) to arbitrary actions; - actions are either MIDI signals (notes, program changes, controller events, or actually any arbitrary MIDI messages), action on the Wiimote LEDs (on, off, toggle, or even an animation for more visible feedback), or a set of such actions: one button could send a program-change and change the LED status to reflect on it; - actions can be grouped in "cycles", and a button/pad can then execute a different set of actions on each hit; useful for toggles or to go through presets; - drumkit pads can generate different actions based on the strength of the hit, allowing for open/closed hi-hat sounds without a separate control for instance. For more information, a little documentation and the pointers to the actual code, see the Wimidi page at: http://roland.entierement.nu/pages/wiimidi.html [About the name: I'm aware that there are several other projects around with the Wiimidi name; however, none of them seem to have seen any activity in recent years. Whether mine will follow the trend or break it, only time will tell.] Roland. -- Roland Mas One... two... one, two, many, lots! -- Lias, in Soul music (Terry Pratchett)

[LAA] [ANN] jack_capture V0.9.70 and Radium V1.9.24

by Kjetil Matheussen

jack_capture ============ jack_capture is a program for recording soundfiles with jack. The default operation of the program is executed by writing "jack_capture" in the terminal without any extra command line options: $ jack_capture ...which will record what you hear in your loudspeakers into a stereo wav file. Download tar balls from http://archive.notam02.no/arkiv/src/?C=M;O=D Git repository: https://github.com/kmatheussen/jack_capture Changelog 0.9.69 -> 0.6.70: * notify user about jack x-runs that occurred during recording (Robin Gareus) * Include timemachine documentation in README file Radium ======= Radium is a music editor with a new and better interface. It's inspired by trackers, but has fewer limitations and uses graphics to show musical data. The advantages of this interface compared to piano rolls (the normal sequencer interface), are that note editing is quicker, and that more musical data fits on the screen. The advantage of this interface compared to trackers, is that note positions and effects are edited graphically, which is both quicker, provides more vertical space, and gives a better musically overview. However, despite it's unusual appearance, it's a design goal for Radium to be straight forward to use, and easy to learn. It should not be harder to learn Radium than any tracker or most midi sequencers. Screenshot: http://users.notam02.no/~kjetism/radium/pictures/radium-1-9-21.png Homepage: http://users.notam02.no/~kjetism/radium/ Source code repository: https://github.com/kmatheussen/radium Most important changes 1.9.22 -> 1.9.24: * Write settings to disk when selecting Set Default Editor Font * Dont crash when using MIDI menu unless the current instrument is a midi instrument * Workaround for bug in newer versions of libbfd, causing compilation to fail. Patch from James Morris * Wait to handle events until program has started. * Remove check for jack in rt midi in check_install script.
