Add the "%" Chord Symbol to repeat the previous chord

[lgvr123]

Your idea

Allow the "%" as chord symbol formatting option and play the previous chord when encountered during playback.

Problem to be solved

In jazz music sheets, the "%" is often used for clarity to say "repeat previous chord".

This sign is at the same time convenient for the musician because the repetition is made really obvious and for writer, because he has not to repeat the previous chord and can experiment without having to change the chord at several places.

Today, the sign "%" can be entered as a Chord Symbol, but MuseScore doesn't play as it considers that sign as an error. And therefore pieces where chords are repeated are not played back correctly. The workaround is to retype all the chord at every repetition but then we loose all the benefits of this sign.

Prior art

iRealPro supports that sign:

This repeat-last-measure sign already exists in the “Repeats & jumps” palette:

Unfortunately, though, it seems that this causes all kinds of havoc with playback of the chords in my 4.2.1 install on Linux. The chords, attached to the rests in the second staff, are not repeated when they should be, interfering with the next chord or playing even long after.

For debugging purposes, this is the file I created: https://musescore.com/user/8377306/scores/14769490/s/scrKtP.

This repeat-last-measure sign already exists in the “Repeats & jumps” palette:

Not exactly. It exists at the measure level. Not at the chord symbol-level.

If you want to reproduce this version of "Witch Hunt" (Wayne Shorter):

using "%" at the measure-level will not work. You need to be able to use it at the chord symbol-level:

Today, using that symbol at the chord symbol-level is feasible (although marked as error during editing).

But MU doesn't play any sound when encountering that symbol (as it is considering it as an error). This is what about is this feature request.

I also want this feature, see it requested numerous times in the Musescore forums: https://musescore.org/en/node/333521 https://musescore.org/en/node/272509 https://musescore.org/en/node/84066
