MusE 2.2 - 2015-01-06 Hi All! Following our plan of making monthly releases. Ah, I mean yearly releases... Well, actually, it's been nearly two years since last stable release. Sorry. Here we are anyway with a new release of MusE, and we think it's a good one! Since last we have moved to github and Andrew has joined the team to, among other things implement LV2 support, which he has done excellently. We are quite happy with the current state and music has been recorded with MusE like never before, some demonstrations are listed below. Major feature improvements of this release includes: * Support for LV2 Synths and effects - effects are supported both in Effect rack and in Arranger - State interface - Worker interface. - Instance-access. - KX studio Programs interface + extended programs interface to support per-channel bank/patch change (only Yoshimi now supports this feature). - Common must-have features: Atom, buf-size, event, options, uri-map, urid. + Other extensions: CV type lv2 ports + LV2_TIME__Position + Atom_Event_Transfer support for plugin<->UI communication + LV2 path MAP and MAKE extensions + LV2 LOG extension - UI interface. Supported UI subtypes: + QT4 + GTK2 + GTKMM2 + X11 + External interfaces (from kx studio specs). + idle callbacks * Yet another MAJOR audio engine and plugin/synth process chain re-write - Track controllers (vol, pan) now sample-accurate and near noise-less Numerous bug fixes and minor enhancements: - Metronome with accent clicks and replaceable clicks - Synths rearranged in separate menus - Reworked the PluginDialog to use a ui file and give more filter possibilities - Added [HOME] button to file open dialog - Ignore undo/redo while recording - Fix crash reported by LakeIshikawa: Pressing delete while clicking or dragging events or parts - Fixed copy/paste problem: Paste copies not clones, if the original parts/tracks have been deleted. - More commands support Undo/Redo, like setting global tempo. - Some new scripts, RemoveAftertouch, TempoDelay - Fix song not 'dirty' on many operations (close was not prompting to save). - Instrument Editor now basically complete: Added Initialization Sequence editor. - Sysex event editor now allows selection from pre-defined Instrument Sysex list. - Revised and edited Roland SD-50.idf by Patrick (split into GM2/nonGM2). - MusE now imports GM2 midi files. (Properly selects GM2 instrument.) - Added a visual metronome to Bigtime - Added line drawing of tempo in graphical master track editor - Fixed bug (issue #342 Moving Aux sends crashes muse) - Added more keyboard shortcuts in midi editors - Mods/fixes to Midi Input Transformator plugin: - When midi in is enabled in drum editor the selected track is moved along with the triggered key - Fixed bug with playback of drums clicking on notes in the new drum editor, it was playing the wrong instrument - MESS synths (esp Deicsonze): Controls (like Track Info program) and synth controls now mirror each other, both ways. - Deicsonze softsynth: Fixed: Not remembering settings + ladspa plugin settings, midi controllers moved to NRPN14 type. - Native VST: Call idle periodically. Makes some plugins like Glitch work, as per LAD mail. - Change window title when there are unsaved changes - Add auto-save feature, when enabled tries to save after 5 minutes - Added pitch control to SimpleDrums, first version - Fixed Ctrl+arrows in the arranger so the track list is scrolled For more information and additional changes see the full changelog at: https://github.com/muse-sequencer/muse/blob/muse_2_2/muse2/ChangeLog News section: http://muse-sequencer.org/index.php/News Download: http://muse-sequencer.org/index.php/Download Demos page: http://muse-sequencer.org/index.php/Demos Forum: http://muse-sequencer.org/forum/ Happy new year from the MusE Team!

by Albert Graef

[Sorry for cross-posting, please distribute.] Linux Audio Conference 2015 - Call for Participation (Due to exceptional circumstances, this announcement comes a bit late, so please note the early deadline of Feb 1st for submissions. We apologize.) We are happy to announce the next issue of the Linux Audio Conference (LAC), April 9-12, 2015 @ JGU | Johannes Gutenberg University, in Mainz, Germany. http://lac.linuxaudio.org/2015/ The Linux Audio Conference is an international conference that brings together musicians, sound artists, software developers and researchers, working with Linux as an open, stable, professional platform for audio and media research and music production. LAC includes paper sessions, workshops, and a diverse program of electronic music. *Call for Papers, Workshops, Music and Installations* We invite submissions of papers addressing all areas of audio processing and media creation based on Linux and other open source software. Papers can focus on technical, artistic and scientific issues and should target developers or users. In our call for music, we are looking for works that have been produced or composed entirely/mostly using Linux and other open source music software. The online submission of papers, workshops, music and installations is now open at http://lac.linuxaudio.org/2015/participation The deadline for all submissions is Feb 1st, 2015 (23:59 HAST). You are invited to register for participation on our conference website. There you will find up-to-date instructions, as well as important information about dates, travel, lodging, and so on. This year's conference is hosted by the Computer Music Research Group (Bereich Musikinformatik) at the IKM (Institut für Kunstgeschichte und Musikwissenschaft) of the Johannes Gutenberg University (JGU) at Mainz. Being founded in 1991, our research group has been among the first German academic institutions in this interdisciplinary field at the intersection of music, mathematics, computer science and media technology. In our media lab students are working almost exclusively with Linux, and in our research we are also devoted to contributing to the growing body of open source audio and computer music software. http://www.musikwissenschaft.uni-mainz.de/Musikinformatik/ We look forward to your submissions and hope to meet you in Mainz in April! Sincerely, The LAC 2015 Organizing Team -- Dr. Albert Gr"af Computer Music Research Group, JGU Mainz, Germany Email: aggraef(a)gmail.com WWW: https://plus.google.com/+AlbertGraef

[LAA] MIDI Trigger LV2 plug-in announce

by Viacheslav Lotsmanov

We released our plug-in which sends MIDI notes by audio peaks under GNU/GPLv3. It has one audio input port and one MIDI output port. It works like trigger-sampler, but more unix-way (without sampler). You just send output MIDI note to sampler that you love. You can save dynamic of your audio signal, just use velocity controls. About "Note-off mode" control you can read here: https://github.com/metachronica/audio-dsp-midi-trigger/blob/6992e837f8cdce1… We'll document it in the future more user-friendly. https://github.com/metachronica/audio-dsp-midi-trigger First release here: https://github.com/metachronica/audio-dsp-midi-trigger/releases/tag/v0.0.1

[LAA] LSA 0.1.0

by Mark Karpov

I would like to announce LSA (LiSt properties of Audio files). This is a minimal, lightweight, console, Unix-style program to list various parameters of audio files. 'Unix-style' means that it tries to do one thing and do it well. LSA also tries to be fast. It has been written in C, it's multithreading (creates one thread per physical core), it uses SSE and SSE2 intrinsics (some people are still using some AMD processors that have no support for SSE4). If you ever have to wait for results, it's because of hard drive speed or decompression. Decompression is performed by Audio File library, so I cannot easily speed up this. LSA is built on top of Audio File library, so it inherits its list of supported file formats: * AIFF/AIFF-C (.aiff, .aifc) * WAVE (.wav) * NeXT .snd/Sun .au (.snd, .au) * Berkeley/IRCAM/CARL Sound File (.sf) * Audio Visual Research (.avr) * Amiga IFF/8SVX (.iff) * Sample Vision (.smp) * Creative Voice File (.voc) * NIST SPHERE (.wav) * Core Audio Format (.caf) * FLAC (.flac) Supported compression formats: * G.711 mu-law and A-law * IMA ADPCM * Microsoft ADPCM * FLAC * ALAC (Apple Lossless Audio Codec) The program currently is capable to display the following parameters: * sample rate; * sample width; * sample format (signed or unsigned integer, single or double precision floating point); * number of channels; * length in minutes, seconds, and hours (if necessary) per file; * total length of all files in actual directory; * number of frames per file; * total number of frames of all files in actual directory; * peak [0..1] per file; * maximum peak among all files in actual directory; * compression scheme. TODO: * efficiently calculate perceived loudness (as per ITU-R BS.1770-3); * efficiently calculate loudness range. LSA repository is here: https://github.com/mrkkrp/lsa Documentation: LSA comes with its own man page License: GNU GPL
