我遇到了另一个chordbox问题，当定义的调音包含升调（或降调）时会发生这种情况。在下面给出的示例中，我定义了打开G和调音一样，但变调夹在第四品. 在第 4 品上放置变调夹，相对于开放 G 的调音是F#-BF#-BD#-F#。当我编译文档时，输出中会出现两个升号，这些升号位于指板螺母处定义的升号之后。例如，D# 后面的音符应该是 E，但在输出中却是 #D#。不幸的是，我不太熟悉 TiKZ 的具体细节，无法自行解决问题，但我想在 中定义的 for 循环或 if 语句中可能存在问题chordbox。

\section{Open G tuning}
With a \textit{capo} on the \textit{4th fret}, the tuning is
F$\sharp$, B, F$\sharp$, B, D$\sharp$, F$\sharp$, which actually is \textit{open B}.
\begin{itemize}
\item Chordbox~\ref{fig:b_chord} is correct.
\item In chordbox~\ref{fig:b6sus4_chord}, \#G should be G$\sharp$,
and \#D$\sharp$ should be E.
\item In chordbox~\ref{fig:e_chord}, x, E, \#A$\sharp$, E, \#G, \#A$\sharp$
should be x, E, B, E, G$\sharp$, B.
\item In chordbox~\ref{fig:e6sus4_chord}, \#A$\sharp$ should be B,
\#G$\sharp$ should be A, \#C$\sharp$ should be C$\sharp$.
\item In chordbox~\ref{fig:e_over_b_chord}, \#A$\sharp$ should be B.
\end{itemize}

答案1
该包使用\if测试将调整列表与需要用于打印节点的音高列表中的条目进行匹配。当调整列表包含诸如 之类的宏时，此方法不起作用\#。
相反，您可以使用\IfStrEq包xstring来进行字符串匹配。xstring已经被使用，chordbox因此使用该包进行检查也是有意义的。
需要重新定义的代码是 handler @typeset pitch。可以\pgfqkeys在加载包后使用语句进行重新定义。
序言中的相关代码：
\usepackage{chordbox}
\makeatletter
\pgfqkeys{/chordbox}{
@typeset pitch/.code 2 args={%
\pgfmathparse{{\cb@tuning}[#1-1]}%
\ifnum#2=0%
\pgfkeys{@replace symbols=\pgfmathresult}%
\else%
\foreach \p in {0,...,11} {%
\pgfmathsetmacro{\stringpitch}{{\cb@pitchnames}[\p]}%
\IfStrEq{\stringpitch}{\pgfmathresult}{%
\pgfmathparse{{\cb@pitchnames}[mod(\p + #2, 12)]}%
\pgfkeys{@replace symbols=\pgfmathresult}%
\breakforeach%
}{}%
}%
\fi%
}
}
\makeatother
结果：
