New features in the nightly builds
As the result of a quick reunion in Germany together with Werner and Thomas, several new features have been merged into master and so now appears in nightly builds. First, a selfie or it didn't happen.
There were 67 open pull requests two days ago. We merged 29, and closed or sorted for later several others. Most of the PR were about bug fixes but some implements new features. While we are into numbers, MuseScore has been written by 64 contributors as of today. Thanks to all of them!
Marc Sabatella implemented this feature. When adding an instrument change to a measure, if the instrument is a transposing instrument, the notes will be transposed accordingly. You should now be able to write this new jazz tune more easily and get the flutist picks a clarinet right in the middle.
Again by Marc Sabatella. It's now possible to make all the empty measure of a staff invisible. It's a new property in Staff Properties dialog called "Cutaway". It's also possible to hide one empty staff while keeping the other empty staff. It's done in Staff Properties > Hide when empty > Always. Combining "Hide when empty / Always" and "Cutaway" gives you a simple but effective ossia.
Igevorse implemented this feature this summer, as part of Google summer of code, under the umbrella of the Portland State University. It will have the bigger impact if you use MuseScore with JACK since it enables to choose precisely which channel and which port an instrument will send midi events to. In JACK it makes it easy to route a given instrument to a given VSTi for example. Note that this feature being quite specialized, it's hidden by default. You need to enable it in Preferences > Score > View for now.
Maurizio "Miwarre" Gavioli worked on tablature support and my guess is that MuseScore is quickly becoming the most complete open source tablature editor. The latest improvement is the ability to mix beam and normal figures in historical tablatures.
A picture is worth a thousand words.
Lots of other fixes
From a new shortcut for sforzato accent (Shift+V) to better control of dashes in lyrics or better glissando editing, there is a lot more to test in nightlies! Pick your favorite new features and test it.
Feedback is welcome on the Tech Preview forum. You can download a nightly from the download page. Keep in mind that files created with the nightlies might not open correctly in MuseScore 2.0.X nor in a future nightly or released version!
