Only one staff-line is displayed instead of 5

[mauxion]

My scorepartwise is displayed with only 1 staff-line despite the fact that I didn't specify in staff-details->staff-lines

I have this problem only with this file. All other my drum notes created with the same way displayed correct. And when I add staff-details->staff-lines to attributes it works as expected.

OSMD version 1.5.8

Expected:

Actual:

My settings:

backend: 'Canvas', drawTitle: false, drawPartNames: false, pageFormat: 'Endless', drawFingerings: false, drawCredits: false, drawMetronomeMarks: false, drawTimeSignatures: false, renderSingleHorizontalStaffline: true, autoResize: false, coloringMode: 0, pageBackgroundColor: '#FFFFFF', performanceMode: false, drawingParameters: 'compacttight', drawUpToMeasureNumber: Number.MAX_SAFE_INTEGER osmd.EngravingRules.RenderClefsAtBeginningOfStaffline = false

Here is file itself: (sorry for .txt format, can't upload .musicxml or .xml) SwingOnRide.txt

You should set osmd.EngravingRules.PercussionOneLineCutoff = 0.

We should probably think about not having one line percussion parts by default, though they are only used when there are 3 or less different tones by default, in which case they usually save a lot of space in scores with multiple parts while still being easy to read.

PercussionOneLineCutoff helped, thank you!

[mauxion]

but now I've got another problem. When I have multiple parts, one-line parts looks not correct. "Backbeat" part has staff-details->staff-lines 1.

Interesting, can you share the file again? We can probably check for the staff-lines attribute and better coordinate it with the positioning and PercussionOneLineCutoff. I haven't seen a score with both one line and multiline drums before.

@mauxion You can try changing PercussionXMLDisplayStepNoteValueShift, though I'm not sure why the notes are so far below the line in this case with default settings. It's possible that different programs export the line height / display step differently. I vaguely remember that it's not always the same mapping. But I could be wrong.

[mauxion]

Sure, here is a file TwoParts.txt

I'm not doing any export from program, this musicxml is generated by my software and I add\remove staff-lines intentionally because I do mix of rhythms\drum beats so I thought that it would be comfortable for user to see parts with one instrument on one line and parts with number of instruments on 5 lines.

This issue is not critical for me, but I really appreciate your help, thx.

JFYI: here is the idea of my app https://www.youtube.com/watch?v=CLCur9BLzFI now I'm working on web version made totaly with kotlin (kotlin multiplaform\koltin-js\kotlin-react)

Then maybe you're not setting display-step correctly. See here: https://www.w3.org/2021/06/musicxml40/musicxml-reference/elements/display-step/

Otherwise, as I said, try adjusting the shift.

I think the line should be an E if I remember correctly, like the bottom line of a treble clef.

thx, I'll do change for display-step in conjunction with adding staff-lines
