I found an interesting problem, I don't know if you have encountered it

The rising and falling marks in the score will be repeated in the bar, and the ideal effect is to appear once in the bar.

can you post the resulting GMN (and reduce it to the strict minimum)? Use https://guidoeditor.grame.fr/ for that.

@arshiacont This is the smallest gmn I can reproduce the problem

@zhwei8090 please next time reduce the example to the strict minimum reproducible on Guido Online Editor. For this one, only one measure is enough. Also pay attention to Copy/Paste issues and use correct github formatting. I did everything this time for you but I won't do this every time! ;)

This is the minimal example:

{
[ \staff<1> \barFormat<style= "system", range="1-2">
\clef<"g2"> \key<-1> \meter<"2/4"> \intens<"p", dy=-3.2hs> \tempo<"[1/4] = 88", dy=1.6hs> 
\stemsDown  c2/2
\slurEnd:1 \bar
\beamsOff b&1/4
\stemsUp \beamBegin:1  a/8 g/8
\beamEnd:1 ]
,
[ \staff<2> 
 \clef<"f4"> \key<-1> \meter<"2/4"> 
 (* measure 1 *)
  \acc( f#-1/8)
 {\acc( f#0/4), a/4, \acc( e&1/4)} 
 { f#0/8, a/8, e&1/8 } \bar
(* measure 2*)
\stemsUp g-1/8 
\stemsDown {g0/4, b&/4, d1/4 } 
{g0/8, b&/8, \acc( d&1/8)} 
]
}

@dfober I believe something is happening here: problem happening on measure one, staff 2 (accidental being repeated).

• If we remove one measure or the first staff problem disappears
• if we remove the barFormat the problem disappears

Any idea?

[dfober]

A more minimal example:

{
[ 
	\barFormat<style= "system">
	\clef<"g2"> \key<-1> \meter<"2/4">
	c2/1
]
,
[ 
	\clef<"f4"> \key<-1> \meter<"2/4"> 
  	f#-1/8
	{ f#0/4, e&1 } 
	{ f#0/8, e&1 } 

	g0/2
]
}

I had already seen that the problem disappears by removing the barformat.
It disappears also by changing f#-1/8 to f#-1/16 (i.e. adding a note after the second chord) .
On my side, nothing happens when removing one measure of the first staff...
I'll have a look.

@arshiacont Sorry, this is my question, pay attention next time
