Creating a pipe organ part with mx::api

[rpatters1]

As you know, I am in the throes of creating a new musicxml export for Finale using MX. The goal is to be the best semantic export it can be, without getting bogged down in engraving details that are unlikely to port to any other program anyway.

I've got brackets working well, but part brackets do not seem to be supported by mx::api. This is how a pipe organ part is supposed to look:

My LLM is telling me I need to do that with <part-symbol top-staff="1" bottom-staff="2">brace</part-symbol> which is not in mx::api. So my question is, is this correct? Is there another way, other than cheating? (FWIW: Finale cheats and creates a hidden extra pedal part.) How much trouble is it to add the part-symbol with mx::core?

I created an issue and PR to support this. Regarding your question as to whether it's right or not, I'm not quite sure. It seems logical. You could ask on the MusicXML GitHub regarding representational correctness.

I'm not sure if you saw this comment: #244 (comment)

I'm wondering if I should promote mx::core in a way as something that one can more easily use directly, whether as it's on build target (without impl+api) or with a flag that promotes the headers to public or something.

In the meantime, as you come across features you need, we can most likely surface them pretty quickly now that we have LLMs for this stuff.

P.S. I'll have less time during the work week, but if you hit another missing feature you can cd into mx and give this a try:

I might be a little picky about certain things if it doesn't follow existing patterns, but it could be worth a try to see what it comes up with for a missing feature.

I did see the comment you linked. Thanks so much for such a quick response and for making MX in the first place. It changed this project from being a sludge to kinda fun.

The only other missing mx::api feature I've found so far is the ability to change instruments & change transpositions in a part. But that's down the road for me.
