[musicxml2hum] Fix missing lines when nowevents includes nonzerodur elements

WolfgangDrescher commented 12 months ago

This PR fixes the missing data lines problem explained in https://github.com/craigsapp/humlib/issues/87.

However, it introduces a new bug. The parts and staves are now in the wrong order:

**kern  **kern  **kern  **kern  **fb    **kern  **kern  **kern  **kern
*part6  *part5  *part6  *part5  *part5  *part4  *part3  *part2  *part1
*staff8 *staff6 *staff7 *staff5 *   *staff4 *staff3 *staff2 *staff1

Expected:

**kern  **fb    **kern  **kern  **kern  **kern  **kern  **kern  **kern
*part6  *part6  *part6  *part5  *part5  *part4  *part3  *part2  *part1
*staff8 *   *staff7 *staff6 *staff5 *staff4 *staff3 *staff2 *staff1

Also note that the **fb spine will be attached to the wrong part and staff now. Do you have any idea how to debug this further?

WolfgangDrescher commented 12 months ago

I debugged this further and it looks like there are two different problems. I use this file for debugging 004-p5-6-m5-7.xml.zip

It looks like it's currently not possible to add figured bass numbers when there is no note in the bass. MuseScore also seems to have problems with this when I open the debugging file:

Both 6 figures should actually assigned to the last quarter note of the measures, and visually below the quarter passing note of piano 1. This will also mess up musicxml2hum and push the **fb spine to another field index.

Regardless of this the **kern spines are not ordered correctly:

**kern  **kern  **kern  **kern
*part2  *part1  *part2  *part1
*staff4 *staff2 *staff3 *staff1

Expected:

**kern  **kern  **kern  **kern
*part2  *part2  *part1  *part1
*staff4 *staff3 *staff2 *staff1

WolfgangDrescher commented 12 months ago

Never mind about the wrong order of the systems. This was caused by my import script to relocate the figured bass numbers from the upper to the lower system of piano 2…

https://github.com/WolfgangDrescher/schiorring-choral-bog/blob/29c04e254cff1f817f38835270377ec8cdbeff75/convert#L59

So the problems seems to be that **fb is mapped to the wrong system:

I will have a look at this.

WolfgangDrescher commented 11 months ago

I have improved the assignment of the figured bass numbers, but it is not perfect yet. I have created a few files that allow to debug this easier: fb-examples.zip

Here is the current status for each example file:

Example 0

MuseScore

fb0

VHV (after)

This is fine. But it's strange that musicxml2hum creates a **recip spine.

Example 1

MuseScore

fb1

VHV before	VHV after

I'm not sure why the figured bass numbers in the oboe are not displayed. I will keep debugging this.

Example 2

MuseScore

fb2

VHV before	VHV after

As there is only one **fb spine per part (note that this is one part with 2 staves): I think it is fine that the fb numbers of both staves are displayed in a single **fb spine.

Example 3

MuseScore

fb3

VHV before	VHV after

Example 4

MuseScore

fb4

VHV before	VHV after

Also here I think it is fine, that the **fb spine is placed after the piano part and thus the numbers are displayed below the upper staff.

Example 5

MuseScore

fb5

VHV before	VHV after

Note that before there was a **recip spine as first spine. I'm not sure why the numbers in the oboe are not displayed. Probably the same issue as in example 1.

Example 6

MuseScore

fb6

VHV before	VHV after
syntax error	syntax error

Notice the **recip spine. I think that for this example the numbers of both staves should be grouped together and 8 1 should be the first data record of the fb spine.

WolfgangDrescher commented 11 months ago

With 9d4510c the results are now much better. But example 6 is still failing though.

Additionally I run the updated musicxml2hum script against the chorales by Niels Schiørring. The results have gotten much better, but I have found some other problems, especially with spine merges and the duration of rests. I will try to fix these as well.

WolfgangDrescher commented 11 months ago

I improved the detection for "slahed accidentals" by allowing vertical,back-slash and sharp-sharp as values in <prefix> and <suffix>.

This does comply with the specs in: https://www.w3.org/2021/06/musicxml40/musicxml-reference/elements/prefix/ https://www.w3.org/2021/06/musicxml40/musicxml-reference/elements/suffix/

Prefix should not contain vertical and back-slash but to keep it compatible with the existing code I allow them in <prefix> as well.

// ...
} else if (suffix == "flat-flat") {
    accidental = "--r";
} else if (suffix == "flat") {
    accidental = "-r";
} else if (suffix == "double-sharp" || suffix == "sharp-sharp") {
    accidental = "##r";
} else if (suffix == "sharp") {
    accidental = "#r";
} else if (suffix == "natural") {
    accidental = "nr";
}

Why does the accidental include r at the end when it is in the suffix? This will probably result in the data token being interpreted as a rest. If this is intended? Should I remove the r there?

craigsapp commented 11 months ago

The r is to "reverse" the position of the accidental:

WolfgangDrescher commented 11 months ago

In b45e76d I removed adding slicep->getDuration() to the duration for ryy@ tokens in data holes. I'm not sure if this is a good idea or if this will cause any other unexpected errors. But it solved may duration problems when importing the Schiørring chorales. Here is a demo MusicXML file: 011-den-lyse-dag-forgangen-er.musicxml.zip

WolfgangDrescher commented 11 months ago

d309393 does improve the handling of cross staff layers (same voice number). If notes are generally in the lower staff but occasionally also appear in the upper staff this works fine as I can add the the total number of voices of the new staff to the current voice index (in case multiple layers change the staff). But is does not yet work well when notes that are generally in the upper staff but occasionally are pushed to the lower staff. The stems are wrong, because the voice should be the new voice index 0 of the new staff and all other voices should be increased by +1 (or the number of voices that change their staff).

Do you have an idea how to solve this problem? MxmlEvent is not aware of the other voices so I cannot modify the voice index of all other voices that need +1 there.

Maybe using high voice indices such as 99 and 98 could be used for layers that need to be pushed in front of the voices index array. ThenreindexMeasure could resolve this. But it is a hacky solution.

7df2873 improves this behavior so that a voice (=same voice number) always has one staff to which it is assigned. If notes should be rendered in another staff than this "root staff" > and < signifiers and RDF**kern above/below lines are added.

Is it okay to push this to humlib like this? I could add an option to musicxml2hum so that this behavior has to be activated with -x / --cross-staff or similar.

Preserving voicing information as you are doing is better than changing the voice to the display staff. We will see what that does in the general case. Then perhaps -X and --no-cross-staff could be used to avoid this behavior.

So I should merge this PR now into humlib?

WolfgangDrescher commented 11 months ago

Yes, I'm happy with it for now. Example 6 of fb-examples.zip – where ideally figured bass numbers should be combined from all voices and stacked – is still not perfect, but it's a special case which I don't need right now. So it's ready for review and to merge. I can implement it, when someone needs it.
