Co-chairs’ meeting minutes – October 2, 2025

MNX

All dictionary objects in MNX can now have a _c object (comment), which can be a string. Adrian has added some comments to a few of the examples by means of demonstration (e.g. here).

Adrian has also added the _x object (extension) to every object for vendor-specific extensions, and as the first example of its use, the MNX documentation now uses the _x object to define areas that can be highlighted in examples to draw attention to particular parts of the encoding.

The documentation now also lists the globally-available attributes in a special section at the bottom of each object page, rather than listing them as if they were specific to that object, which you can see e.g. here.

Adrian has also changed the word “keys” to “attributes” throughout the documentation as this seems to fit better with our use of the word “object”.

Adrian discovered via Reddit a new GitHub project from Oliver Paddock called Capo-Compose that defines a new text-based language for describing music notation that compiles to MNX.

Up next, Adrian plans to complete the encoding of multi-note tremolos, which the co-chairs discussed in the London workshop back in July (issue #119).

MusicXML

The attachment of directions to grace notes was discussed (#602) and it was confirmed that the documentation is correct.
