TU Studio - Seminar: Unorthodox Sound Synthesis

by Henrik von Coler

The TU Studio will be hosting a workshop, free of charge and open to everyone interested: Unorthodox Sound Synthesis Daniel Mayer (IEM Graz) Topic of the seminar will be selected procedures that don’t fall into the area of classical sound synthesis resp. transformation as well as unorthodox combinations and applications of classical techniques. In that context participants will be encouraged to develop and implement own ideas. Possible topics (depending on knowledge and interest): buffer modulation, single sample feedback, wavefolding, synthesis with ordinary differential equations, functional iteration synthesis, variants of granular synthesis. Requirements: Basic knowledge of sound synthesis. The seminar refers to some of the lecturer's implementations in SuperCollider, therefore basic knowledge of SuperCollider is desirable but not absolutely necessary. The workshop includes three sessions - please bring your laptop (with SuperCollider installed): Tuesday, 11.02. Wednesday, 12.02. Thursday, 13.02. 18:00-21:00 TU Studio Einsteinufer 17c, Room EN-324 Links: https://daniel-mayer.at https://github.com/dkmayer/miSCellaneous_lib For further questions, please contact Daniel Mayer: mayer(a)iem.at Students can get 3 credit points for the module "Musikinformatik+Medienkunst" in combination with a project related to the seminar. --------------------------------------------------------------------- ---------------- --------------------------------------------------------------------- ---------------- Henrik von Coler Elektronisches Studio, Fachgebiet Audiokommunikation Technische Universität Berlin Fakultät I Geistes- und Bildungswissenschaften Institut für Sprache und Kommunikation Einsteinufer 17c, Sekr.

Find all "beat offsets" from .mscx (MuseScore 3 uncompressed) or exported MusicXML?

by Kevin Cole

Hi, I'm not terribly well-versed in either music theory or the capabilities of all the various musical software tools out there in the happy land of Linux (in my case, Arch Linux). I'm looking to "shortcut" a process: I want to generate two sets of WebVTT captions / subtitles for an MP3 that was produced from a MuseScore 3 file. One set will be chord notations like "F#m/A". (The other will be lyrics. Sort of a karaoke thing with chords.) Since the chord changes fall on a beat, and there are no alterations in the time of this piece -- i.e. no "slower" or "faster" parts, but there are time signature changes, it should be a programmatically solvable problem. The simplest approach seemed to be to generate a starting and ending time for each beat, and go through a parseable file and parse out which chord falls where and attach it to the appropriate element in the list of durations. The thought occurred that, if I have the duration of the file, and either the uncompressed MuseScore or uncompressed MusicXML, there might be a clever tool or Python module to parse the file and come up with the total number of beats, and then divide the duration by that. Rather than invent the wheel from scratch, I thought I'd ask if there was already a wheel -- or if the wheel I'm building ultimately won't roll. ;-) Is this making any sense, and are there such handy tools? Thanx.

Ninjas2 sample slicer plugin released (v.0.2.0)

by Rob van den Berg

Hi all, I've updated Ninjas2 audio sample slicer plugin. Source and binaries (linux/windows/mac) are available at : https://github.com/rghvdberg/ninjas2/releases/tag/v0.2.0 readme : https://github.com/rghvdberg/ninjas2/blob/master/README.md >From the readme: #Goal: Easy to use sample slicer, quick slicing of sample and auto-mapping slices to midi note numbers. # Intended usage: Primarily targeted at chopping up loops or short ( ≈ 10 - 20 seconds) samples. Think drum loops, vocal chops etc. Currently there's no limit on imported sample length. User can play the slices using midi notes and change the pitch with midi pitchbend. # Downloads: Linux, Windows and Mac binaries for several architectures are available here. There are no installers, just unzip and copy the plugin to an appropiate location. # New Features - redesigned interface - controls are grouped in Global, Slicing and Slice - the Slice box shows the currently selected slice number - keyboard - click on key to play slice - red dot on key indicates which slice is currently selected in the waveform display - keys that don't have a slice mapped to them are greyed out # Known Bugs and Limitations - some host don't work very well with the lv2 version - zrythm and qtractor had trouble with the lv2 version but worked fine with the vst - ardour, carla and muse3 worked well with the lv2 - care should be taken when automating the playmodes and adsr - the automation is sent to the currently played note (slice), when multiple slices are played, this leads to "undefinied behaviour"

liquidsfz-0.2.0

by Stefan Westerfeld

liquidsfz-0.2.0 has been released The main goal of liquidsfz is to provide an SFZ sampler implementation library that is easy to integrate into other projects. A standalone jack client and a LV2 plugin is also available. liquidsfz is implemented in C++ and licensed under the GNU LGPL version 2.1 or later. The release tarball can be downloaded here: https://github.com/swesterfeld/liquidsfz#releases Overview of Changes in liquidsfz-0.2.0: --------------------------------------- * Provide LV2 plugin * Support for <control>/<global>/<master> sections * Handle #define * Lots of new opcodes supported, including - key switches - crossfading for layers - more amp-related opcodes - allow changing more parameters using CCs * API additions - load progress function (Synth::set_progress_function) - global gain factor (Synth::set_gain) - provide list of CCs supported by .sfz file (Synth::list_ccs) - support pitch bend (Synth::add_event_pitch_bend) -- Stefan Westerfeld, http://space.twc.de/~stefan

Guitarix2 release version 0.39.0

by Hermann Meyer

I'm pleased to announce the release of guitarix2-0.39.0 A virtual guitar amplifier for Linux running with jack (Jack Audio Connection Kit). This is a maintenance release which mainly is meant to get rid of the python2 build dependency. Changes are so far: - updated waf version to 2.0.19 by Andreas Degert - cleanup all GTK(mm) calls to be able to build with -DGSEAL_ENABLE flag (prepare to update to GTK3) by Hubert Figuière - update Russian Translation by Valeriy Shtobbe and Olesya Gerasimenko (Basealt Translation Team) - bind lv2:enabled to guitarix on_off switch and remove from UI by Hermann Meyer - update all build scripts to use faust version 2.15.11 by Hermann Meyer - add new option -E --hideonquit, to make the UI experience smooth when used as LV2 plugin (via Carla export) by Hermann Meyer - add exit handler and warning when sample-rate is above 96kHz by Hermann Meyer You could get it here: https://sourceforge.net/projects/guitarix/ regards hermann

A new year, a fresh start

by Jeremy Jongepier

Dear all, First of all a happy 2020 (even though it's way past Epiphany)! So what's the fresh start about? Well, registration of the linuxaudio.org domain has been handed over to yours truly so if you need any DNS changes regarding any linuxaudio.org subdomains then I can take care of that now directly. Thanks Daniel James of 64 Studio for taking care of the domain for so long! Other part of the fresh start is that I migrated the web server to a new cloud region which is faster and more performant. I just changed all the DNS records so if you spot anything weird that just worked before then please let me know! The mail server will follow this weekend so if mail seems a bit flaky the coming weekend then you know what might cause it. Best regards, Jeremy

[ANN] Qtractor 0.9.12 - The QStuff* Winter'19 Release batch #3

by Rui Nuno Capela

Greetings, just one last time! Qtractor 0.9.12 (winter'19) is released! The change-log is rather short but nevertheless: - Basic key-signature has been added to tempo, time-signature and location markers map. - MIDI Clip editor (aka. piano-roll) horizontal and vertical splitter sizes, widths and heights resp. are now preserved as user preferences and also to session state. - Second attempt to fix the yet non-official though CMake build configuration. Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.
