[Android|OT?] CamSynth - Just an experiment

by Florian Paul Schmidt

Hi, I don't know if this is on-topic or off-topic - technically it runs on a linux, but then, maybe, just, no, no Android on LAD?? :D But anyways: I played a little with Android Development and hacked up a little experimental Synthesizer app. https://github.com/fps/android_camsynth https://play.google.com/store/apps/details?id=io.fps.camsynth It's free and open source and renders 8 voices (on my LG-P500) with a trivial (and wrong :D) synthesis method where the voice gains are determined by the camera image at a 8 x 8 px resolution.. I guess it's somewhat a minimal project which can be instructive to some (the synthesis part is implemented in C via JNI). And the code is very small.. Have fun, Flo

Some further questions about xruns and jackd2

by S. Massy

Hello, When I see something like: JackEngine::XRun: client = X was not run: state = 2 JackAudioDriver::ProcessGraphAsyncMaster: Process error ...Am I correct in assuming that client X failed to read/write to its end of the graph in time and is where one should investigate? Does State = 2 have any particular meaning? Thanks. Cheers, S.M. --

[ANN] AnalyseLV2 0.02

by S. Massy

Hello, Here is release 0.02 of AnalyseLV2. Improvements in this release: - Now handles non-integer scale points (useful for plugins keeping all values between 0 and 1, such as MDA plugins). - Scale points and their ports are now printed in the correct ascending order. Get it at http://www.wolfdream.ca/x/misc/AnalyseLV2-0.02.tgz Read below if you don't know what this is... AnalyseLV2 is a PERL module, AnalyseLV2.pm, and a front-end script, analyselv2, which parses the output of such utilities as lv2info and lv2ls and outputs it in a format closely modelled on that of analyseplugin for ladspa. I believe this makes using LV2 from the command line, using such hosts as Ecasound, lv22file, and lv2proc, much more straightforward. The backend module can also be used by other PERL programmes (Joel Roth's Nama already uses it) to receive the information pertaining to a given plugin already broken down in a key/value structure. Please consult the README for installation instructions and basic information. Cheers, S.M.

Praxis LIVE screencasts / good screencast software for audio?

by Neil C Smith

Hi All, Firstly, finally got around to some screencasts of Praxis LIVE in action - http://praxisintermedia.wordpress.com/2012/07/30/video-rough-cuts-1/ These are just 'rough cuts', unedited except titles and no voiceover. Only first 2 have audio, and the audio on the second is a little off in places (see below!) Secondly, anyone got a suggestion for screencast software that's good at glitch free audio? These are done with Kazam. First is mostly OK, but the second is a little glitchy. Finding only about 1 in 4 captures is any good - all sorts of weird glitches and sometimes speed issues, though the audio playback while recording is fine. Thanks and best wishes, Neil -- Neil C Smith Artist : Technologist : Adviser http://neilcsmith.net Praxis - open-source intermedia system for live creative play - http://code.google.com/p/praxis OpenEye - specialist web solutions for the cultural, education, charitable and local government sectors - http://openeye.info

[ANN] Virtual MIDI Piano Keyboard (VMPK) 0.5.0 has been released

by Pedro Lopez-Cabanillas

Virtual MIDI Piano Keyboard is a MIDI events generator and receiver. It doesn't produce any sound by itself, but can be used to drive a MIDI synthesizer (either hardware or software, internal or external). You can use the computer's keyboard to play MIDI notes, and also the mouse. You can use the Virtual MIDI Piano Keyboard to display the played MIDI notes from another instrument or MIDI file player. Changes for v0.5.0: * RtMidi 1.0.15 patched by Gilles Filippini <pini(a)debian.org> enabling several MIDI drivers to be compiled at once, and allowing the user to select one at runtime. * Fixed Bug #3507732. Transpose does not update correctly the octave in note name. Thanks to Patrick Meaney for the bug report * Fixed Bug #3503768. Removing the shortcut for an action having default shortcut keys, the change is not saved upon exit, so the shortcut appears again the next execution. * Fixed Bug #3502659. Saved preferences not set correctly. * New implementation of the Network MIDI driver (UDP multicast). * MIDI channel state enforcement (RFE #3517750) * MIDI IN Omni mode. * Independently enable/disable note input using keyboard, mouse, and touch screen. * Note highlight color policies (single, double, one color for each MIDI channel, one color for each grade in the chromatic scale). Color palettes editor dialog. Option to show a colorized scale. * XML comments within keyboard map files are allowed. Requirements for all platforms: CMake-2.8 and Qt-4.8 or later. Please use the mailing list <vmpk-devel(a)lists.sourceforge.net> for questions and comments. Thanks.

[ANN] MusE 2.0.1 released

by Robert Jonsson

MusE 2.0.1 has been released! This is a bug fix release that mainly fixes a problem with moving plugins in the plugin rack. Some changes: - Fixed controllers go wacky after moving effects rack plugins up/down. - Changed naming convention for recorded wave files to include track name and it's take number - Use cmake's own FindPythonLibs module instead of pkgconfig to detect Python - Updated Czech translation from Pavel Fric - Increased zoom range a bit in arranger For more information and additional changes see the changelog: http://lmuse.svn.sourceforge.net/viewvc/lmuse/tags/muse_2_0/ChangeLog?revis… Find the download at: https://sourceforge.net/projects/lmuse/files/ Happy MusEing!

The big changes since 1.1 are as follows: * Moved to qt4, this affects the visuals and potentially improved portability * Graphical automation in the arranger * A new score editor * MusE now defaults to using midi through Jack, -A enables native alsa support * New style MDI gui with a bunch of configuration options to satisfy all tastes * Redone midi editing tool dialogs with lots of new functionality * Lots and lots and lots of internal small and big changes to improve stability, speed and functionality * PSIIF support (support for: probably something important I forgot) A much condensed list of changes since the last beta are as follows: - Sync fix: MusE now records tempo changes from externally clocked midi. - Finally! Audio controller playback has smooooth frame resolution even with large audio buffers. - Feature: Midi control of audio paramters. - Lots of automation improvements - Switched to use JACK midi - Added: -A switch: "Force inclusion of ALSA midi even if using Jack". - Lots of leaks removed - Added colorhints to iR and oR routing buttons - Templates: File dialog: Lots of changes - Lots of widget focus fixes - Allow loading of DSSI synths in LADSPA browser. - Midi editors: Added "Delta Mode" button to Note Info toolbar. The full changelog is available at: http://lmuse.svn.sourceforge.net/viewvc/lmuse/tags/muse_2_0/ChangeLog?revis… Find the download at: https://sourceforge.net/projects/lmuse/files/ Also a big thanks to everybody who has helped translate, find and fix bugs and otherwise been lending a helpful hand!

The alpha indicates this is an early version so it's mainly - a teaser to spread the word. - an early adopters build. - to welcome developers who want to port MusE to other platforms. MusE has now been completely ported to the Qt4 architecture and we (mainly Tim and Orcan) are busy to make it even better than before, lots of gui stuff being reworked. MusE now also sports a new version of the DeicsOnze, DX11 emulating softsynth, up from version 0.2 to 1.0. The homepage has received a new look that we hope will give a better indication of what MusE is and does. Do visit http://muse-sequencer.org.

ANN: New version of Pd-L2Ork Software Featured in the Inaugural VT ICAT Maker Workshop for Middle-School Kids

by Ivica Ico Bukvic

Apologies for x-posting... It's been a busy summer--pd-l2ork <http://l2ork.music.vt.edu/main/?page_id=56>has been making big strides towards becoming a robust full-fledged digital signal processing tool. The latest version includes revolutionary preset_hub and preset_node system that supports a wide range of data types as well as abstractions. It is essentially Pd's counterpart toMax's pattrstorage <http://cycling74.com/docs/max5/refpages/max-ref/pattrstorage.html>. We've also squashed dozens of bugs and clean-ups making pd-l2ork better than ever. Perhaps the most exciting improvement involves Pd-L2Ork'sK12 module <http://l2ork.music.vt.edu/main/?p=1964>geared towards elementary, middle, and high school students. The new version has over 40 objects/abstractions, allowing students to seamlessly interact with both Wiimotes andSARC iteration of Arduino Uno devices (a.k.a. Sarcduino firmware) <http://www.musicsensorsemotion.com/2010/03/08/sarcduino/>. And this very version together with 15 L2Ork stations is being used this week by more than 30 middle-school students as part of the inauguralICAT K12 Maker Workshop <http://www.icat.vt.edu/> taking place in Virginia Tech Institute for Creativity, Arts & Technology's Studio 1. So, head on over to the L2Ork's software page <http://l2ork.music.vt.edu/main/?page_id=56>and check out what the latest version of pd-l2ork is all about ;-) 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 Department of Music Blacksburg, VA 24061-0240 (540) 231-6139 (540) 231-5034 (fax) disis.music.vt.edu l2ork.music.vt.edu ico.bukvic.net

[ann] out now petri-foo 0.1.85

by James Morris

Petri-Foo, the fork of the soft-sampler known as Specimen, has a new release, 0.1.85, available: http://sourceforge.net/projects/petri-foo/files/Source/petri-foo-0.1.85.tar… This new release brings two and a half new features with it: (1.0) Non Session Management support (2.0) 'Full Save' functionality (2.5) Import (1.0) NSM support can only be built if the system has liblo installed. If liblo (the lightweight OSC implementation) is _not_ installed petri-foo will be built _without_ NSM support. (2.0) "Full Save" functionality increases the portability of Petri-Foo's 'dish files'. A dir is created (the bank dir) containing the dish file along with symlinks to external samples used. the bank dir can then be archived using `tar -h`. To use full save, just select 'full save as' instead of 'save as' from the file menu. Selecting 'save' will do the right thing after doing so. (2.5) The import function is very self explanatory: it loads a dish file without deleting the existing patches. http://sourceforge.net/projects/petri-foo/files/Source/petri-foo-0.1.85.tar… Further resources: http://petri-foo.sourceforge.net https://sourceforge.net/tracker/?group_id=404816 http://lists.sourceforge.net/lists/listinfo/petri-foo-devel http://github.com/jwm-art-net/Petri-Foo Cheers, James.
