The alternate segno sign in musescore is shown incorrect.

The sign mustn´t be above the stave (like a normal segno) but attached (or overlayed) to the bar line of the bar it´s reffering to.

So the alternate segno must be shown more like a common repeat sign (or an akkolade) instead of a normal segno.

Once attached to a bar, it has to attach to the barline of the actual bar throughout and down the whole socre. (For it´s a system sign)

The upper and the lower end of the serpent must overlap the lines. (A size of 30 was alright in my case, but I had to attach it manually (not with strg + downarrow) because it wouldn´t have been symmetric.)

Like an akkolade the serpent would be stretched lenghtwise accross each voice of a register only interrupted if the register changes.

So maybe the code of musescore can combine the "jump features" of a normal segno with the layout characteristics of a repeat sign (akkolade). (Only with the serpent "winded round" the bar line)

This issue has already been mentioned in a 2014 thread. But hasn´t been executed so far. (The alternate segno still is nothing but a different design for a normal segno)

That´s the only way I know this sign is meant to be used (I never saw the serpent above the staff)

Thanks for filing it. And apparenlty you set yourself to also implement in? If not, better unassign yourself from this (and change prioroty to normal, major is reserved for serious restrictions in using MuseScore and corner case crashes, this feature here definitly doesn't qualify)

BTW: here's a possible workaround: add a new text style, as a copy of "Repeats Text Left", and change the vertical alignement from bottom to center then use that text style with this Segno Variation.

Actually getting this into the MuseScore source might even be the real fix?

As mebtioned in that thread, we are awaiting any information from an established authority to describe the most correct usage, since clearly examples exist showing multiple different usages, and Gould does not address the topic.

With the fact that there are multiple "correct" usages in mind, maybe the easier solution is to simply include multiple versions of this on the palette, one explicitly set to 0 vertical offset (or otherwise adjusted as necessary achieve that effect). I don't under the name text styling system so I can't say what's involved in doing that for 3.0. But I believe this could probably be accomplished directly in 2.1. Not sure how it would work if the user changed the vertical offset in the text style.

At least Lilypond seems to handle this Segno variation only on the bar line:

http://lilypond.org/doc/v2.19/Documentation/notation/bars#index-segno
http://lilypond.org/doc/v2.19/Documentation/notation/long-repeats#index…

in opposite to other repeat signs:

Without having another reference for the most correct usage we could compare the usage of the sign in other music notation programs.

Seems there it a) is bigger than our's and b) always goes with a double barline.
Makes me think we should implement it as a barline (with a jump tag/marker property), in addition to the 'real' segno variation, so we can have it both ways

For me the reason to implement this as an alternate barline style would be the fact that apparently this is intended to be used on all staves, not just the top as with normal segnos. How that looks internally in terms of whether there would also be a marker element is another matter.
