Jean Abou Samra: Import snippet from LSR

Import snippet from LSR

Sometimes for short polyphonic pieces – and to make the source more readable –, it can be helpful to use <code>\parallelMusic</code>.

Troubles come with repeats that should be entered as

<pre>\parallelMusic #'(voiceA voiceB) {
\repeat volta 2 { mes.1 mes.2 ... mes.n } |
\repeat volta 2 { mes.1 mes.2 ... mes.n } |
}</pre>
so the code becomes less readable and the use of <code>\parallelMusic</code> less understandable.

This snippet is a workaround that shows another way to write repeats in <code>\parallelMusic</code> mode by simply adding a bar at the end of the score.

It also handles the wanted repeats in the midi output.
