&gt; Hello all.<br>
&gt;<br>
&gt; I have another question, this time about percent repeats. I&#39;m <br>
&gt; repeating a long, complex keyboard figure which extends across both <br>
&gt; staves, and using a combination of MagnifyMusic reduction and percent <br>
&gt; repeats to keep things manageable. The only thing is that the repeat <br>
&gt; slashes only appear on one staff; I&#39;d like to mirror them in the <br>
&gt; other, just so things look symmetric.<br>
&gt;<br>
&gt; There&#39;s a function in the documentation for generating arbitrary <br>
&gt; percent figures in the score...<br>
&gt; makePercent =<br>
&gt; #(define-music-function (note) (ly:music?)<br>
&gt;        &quot;Make a percent repeat the same length as NOTE.&quot;<br>
&gt;        (make-music &#39;PercentEvent<br>
&gt;                          &#39;length (ly:music-length note)))<br>
&gt; ...so I assumed I could just substitute a RepeatSlashEvent for the <br>
&gt; Percent Event. Turns out I can&#39;t; it compiles fine, but throws an <br>
&gt; error when I try to use it.<br>
&gt;<br>
&gt; ERROR: Wrong type (expecting exact integer): ()<br>
&gt;<br>
&gt; I could just shove the repeat slashes into the middle between the <br>
&gt; staves, but I&#39;d rather have them mirrored if I could. Is there some <br>
&gt; way to make a function like this that works, or is there a completely <br>
&gt; different path that makes more sense?<br>
<br>
<br>
<br>
In the lower staff, instead of<br>
<br>
     s1 s1 s1<br>
<br>
use<br>
<br>
     \repeat percent 6 { \repeat unfold 16 { s32 } }<br>
<br>
You have to use \repeat unfold 16 { s32 } instead of s2 because<br>
the durations inside \repeat percent determine how many slashes<br>
are printed.<br>
<br>
Cheers,<br>
