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"

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
