Hi everybody, I'm glad to announce the first pre-release of SoundTracker v1.0.1 You can download it here: https://sourceforge.net/projects/soundtracker/files/ I would say, v1.0.1 is a big step ahead from v1.0.0. It contains numerous improvements everywhere and some important bugfixes, among which I have fixed the annoying (at least for me) performance issue with Gtk-2 bitmap graphics. Now SoundTracker is about so fast as old Gtk-1 variant. Regards, Yury. What is new in soundtracker-1.0.1-pre1 (21-Feb-2020): * Improved mouse usage in the instrument editor (yaliaev) * Indication of pressed keys in the instrument editor (yaliaev) * Better look of the scopes (yaliaev) * Record indicator in the sampling monitor (yaliaev) * More configurable colors (yaliaev) * Logarithmic scale of the amplification slider; numeric entry in addition to the slider; ability to determine the optimal amplification (yaliaev) * Extended editor on the module info page with functions of exchanging and copying samples and instruments, mixing samples and tuning a sample using another one as a reference (yaliaev) * Different selection modes in tracker, selection can be extended with SHIFT (yaliaev) * A new method of waveforms' drawing in the sample displays in addition to the existing one (yaliaev) * Automatic file extension adding (optional) (yaliaev) * More convenient keybindings; new keybindings are added (see README) (yaliaev) * Some more keys are made configurable including that for song / pattern playback (yaliaev) * New playing modes are added: Playing selected block and Playng from cursor, playback looping control (yaliaev) * Facility for loading somewhat broken modules (yaliaev) * Stepping volume / FX parameter with mouse wheel (yaliaev) * Improved export to audio file (yaliaev) * Volume column can be displayed like in FT2, with letters, mnemonics and optional decimal volume representation (yaliaev) * Jack input driver (yaliaev) * Improved live recording using PC keyboard: better key pressing / releasing times are recorded using FXes (yaliaev) * Some other small improvements (GUI, usability) (yaliaev) * Some bugfixes including the CPU overhead with graphics (yaliaev)

dssi-vst lives again. Some kernel futex patches applied?

by Tim

Hi all. Long time no talk. Sorry for the cross-post. When I last tried dssi-vst in November, I got it running but with a continuous stream of errors and xruns. That was apparently caused by kernel futex problems. dssi-vst was assumed dead. But I just tried again and it's working 100% no errors or xruns. Seems maybe these kernel futex patches have been applied? https://lkml.org/lkml/2019/7/30/1399 https://lkml.org/lkml/2019/7/30/1398 Anyone in a position to try and verify? May have to edit a wee path or two in the Makefile. I can't believe it, it's working for over an hour now... Thanks. Tim.

spectmorph-0.5.1

by Stefan Westerfeld

spectmorph-0.5.1 has been released. If you haven't watched our video tutorial for the instrument editor added in 0.5.0, you can do so here: https://youtu.be/JlugWYPDp84 This release introduces statically linked generic 64 bit linux plugin binaries, so even if the packages don't match your linux version, you should be able to install these without compiling. This is a new feature, let me know if it doesn't work for you. Overview of Changes in spectmorph-0.5.1: ---------------------------------------- * Add new LFO modes (saw, square, random) * Support generic 64-bit linux binaries - new linux file selector (no longer needs Qt) - ship font for static build * Fix crashes caused by fftw planner being used from multiple threads * Ported all python2 code to python3 * Support midi all notes off * Implement LV2 StateChanged * French translation for smjack desktop file (Olivier Humbert) * Thread race fix (JP Cimalando) * Minor fixes and cleanups What is SpectMorph? ------------------- SpectMorph is a free software project which allows to analyze samples of musical instruments, and to combine them (morphing). It can be used to construct hybrid sounds, for instance a sound between a trumpet and a flute; or smooth transitions, for instance a sound that starts as a trumpet and then gradually changes to a flute. SpectMorph ships with many ready-to-use instruments which can be combined using morphing. SpectMorph is implemented in C++ and licensed under the GNU LGPL version 3 Integrating SpectMorph into your Work ------------------------------------- SpectMorph is currently available for Linux, Windows and macOS users. Here is a quick overview of how you can make music using SpectMorph. - VST Plugin, especially for proprietary solutions that don't support LV2. (Available on Linux and 64-bit Windows/macOS) - LV2 Plugin, for any sequencer that supports it. - JACK Client. Links: ------ Website: http://www.spectmorph.org Download: http://www.spectmorph.org/downloads There are many audio demos on the website, which demonstrate morphing between instruments. -- Stefan Westerfeld, Hamburg/Germany, http://space.twc.de/~stefan

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"
