[LAD] linuxaudio.org scheduled maintanance

by Robin Gareus

Hi all, I'm not quite sure how to interpret this, but it sounds like linuxaudio.org will be offline for a short time (failover period) coming Saturday January 12th 8am EST. -------- Original Message -------- Just wanted to make sure you were aware of the upcoming maintenance this Saturday. Maintenance for the central storage system known as minnow.cc.vt.edu is schedule for Saturday, January 12 starting at 8am. Several hardware components in the filer head needs to be replaced. Since this is a cluster storage system, the maintenance will be performed in failover mode, so minnow services will continue to be available. During the failover, services will pause until the failover is complete.

[LAD] [ANN] Sqorlatti 0.1.0 (Debut of a music notation program.)

by M Donalies

Yet another music notation program to pollute the internet. It's still just a baby, but it already implements at least a few bugs. It's not really ready for general use yet. The user interface is still rather lacking and there are way too few sanity checks, but it does read and write native *.sqo files (an xml format), and supports a crude and low-quality export to standard MIDI files. The Staff Editor can display standard notation and tablature moderately well, and work is ongoing to produce better percussion staff and chord staff display. Tracks can be nested. Staffs can be grouped. The score format supports multiple simultaneous time signatures. Currently, it's just for display and editing. There's no playback yet. Website: http://sourceforge.net/projects/sqorlatti Download (bzipped source tarball): http://downloads.sourceforge.net/sqorlatti/sqorlatti-0.1.0.tar.bz2 It's written in C++ and uses Qt4. There's no config or anything yet, just Qt project file. So, as an ordinary user: 1. Create a Sqorlatti (or whatever you want to call it) directory somewhere. 2. Unpack to the directory. 3. CD to the directory. 4. qmake 5. make 6. Install the Sqorlatti.ttf font. It's located in the fonts subdirectory. In KDE you can install it by going to System Settings and clicking through Computer Administration / Font Installer / Personal Fonts / Add. 7. To run, type ./Sqorlatti examples/Air.sqo This will open one of the examples. Due to a bug in the program (just found it today!), you have to start the program with a file. Any *.sqo file in examples will do. Once the program is running, you can open any other *.sqo file. If you open Staff Editor and the staffs looks huge and filled with garbage characters, you forgot to install the font. UserManual.pdf provides a small amount of documentation on how to use the program. It's not all that well developed yet. Developer documentation can be generated using doxygen. Just type doxygen to generate html documentation in the doc directory. You can fiddle with doxyfile if you want to generate documentation in other formats (e.g. latex). -- 7:8

[LAD] [ANN] ladspamm - a small c++ library for handling LADSPA plugins

by Florian Paul Schmidt

Hi, GIT repo: https://github.com/fps/ladspamm DOXYGEN docs (very minimal): http://fps.github.com/ladspamm For my own small side projects I needed a little c++ wrapper lib around LADSPA plugins. Since someone else might be interested in it, too, I put it on github. ladspamm::world world; ladspamm::plugin_instance instance( world.libraries[0]->plugins[0], 48000 ); instance.activate(); instantiates and activates the first found plugin in the first found library.. This is version 0.0.1 so expect bugs and missing features.. Have fun, Flo -- Florian Paul Schmidt http://fps.io

[LAD] CAPS 0.9.3 and 0.4.6

by Tim Goetze

CAPS 0.9.3's guitar amplification contains four new tonestacks, distortion asymmetry dependent on output power and other sound improvements. The modulation of the mono chorus has been smoothened, and the Plate default parameters have been restored to be nearer the more reverberant response of the older versions. http://quitte.de/dsp/caps.html There's also a 0.4.6 release, stamped 'obsolete', containing all the plugins that were in 0.4.5 but did not make the cut to 0.9. There are no duplicate plugin IDs, and the library is differently named, so both versions can co-exist on one system. http://quitte.de/dsp/caps.html#Older_Versions

Proper detection and optional inclusion of jack/session.h has been added as well. AFAICT, this should take care of the last of the jack1 issues. Could you try the latest in v0.14.97-dev and let me know how it goes? Thanks! --ww

[LAD] ANN: Audiality 2 1.9.0 - Refactored, renamed, rearmed!

by David Olofson

Audiality 2 1.9.0 - Refactored, renamed, rearmed! ------------------------------------------------- "Audiality 2 is a realtime audio and music engine, primarily intended for video games. While it supports traditional sample playback as well as additive, subtractive and granular synthesis, the distinctive feature is subsample accurate realtime scripting." Audiality 2 (previously released as ChipSound) is used for sound effects and music in the game Kobo II. The name originates from an old structured audio and sampleplayer engine, originally developed as part of the XKobo port Kobo Deluxe. The old engine is no longer maintained, so the new one, which has similar goals but much greater potential, is now inheriting the name. Key features: * Microthreaded realtime scripting engine * Modular voice structures * Subsample accurate timing * Designed for hard realtime applications * No hardwired voice/channel/bus structures * No hardwired "MIDI-isms" or similar * No hardwired instruments or songs - only programs * Lock-free timestamping C API * Audio I/O drivers: * SDL audio * JACK * Application provided drivers * System drivers: * libc malloc (soft RT) * Application provided drivers * Implemented in portable C * zlib license Official site: http://audiality.org/ Direct download: http://audiality.org/download/Audiality2-1.9.0.tar.bz2 Related; Kobo II site: http://kobo2.net/ -- //David Olofson - Consultant, Developer, Artist, Open Source Advocate .--- Games, examples, libraries, scripting, sound, music, graphics ---. | http://consulting.olofson.net http://olofsonarcade.com | '---------------------------------------------------------------------'
