dir="bounce" on pedal should show a star

[rettinghaus]

When using <pedal dir="bounce"> it sould look like

but only looks like

The code:

    <pedal dir="bounce" staff="2" tstamp="4"/>

Would result in the two symbols being rendered (when using in old-style pedaling)?:

That would be handy, but I can imagine complications related to implementing:

How would it be handled graphically across system breaks and barlines:

[rettinghaus]

If I understand this correctly it is basically one symbol, other than in your scan @craigsapp So it should be rather easy to accomplish. Align the "Ped" and print a star in front of it.

This is what lilypond would make out of it:

[lpugin]

How would a bounce be represented with lines when occurring at the end of a system? Does anybody have an example?

[craigsapp]

This is Etude Op. 10, No. 9 by Chopin.

Most of the editions put the pedal up aligned with the last 16th note of each beat. And if encoded as a bounce, then the old style Ped/* notation would put the pedal up on the previous system and the pedal down at the start of the next system.

In a modern pedal line, the bounce at a system break should probably also be split across the break as well: The up-line would be at the end of the measure at the last system (at the barline), and the down line would be at beat 1 of the next measure.

Notice that there is more space between the */Ped when it is across the barline in these editions found in IMSLP, probablyl because all of these editions put the pedal-up on the last note, so not really encoding as a bounce.

The first pedal up in measure 4 is interesting: it is one 16th note before the rest of the pedal-ups in its beat position...

The above is interesting since the pedalling cannot be viewed as a bounce (the pedal up is one 16th note before the next beat, and also interesting is that the pedal up is dropped where other editions start the simile/segue.

This is closer to a bounce concept as there is only a pedal down (implying that there must immediately be a pedal up just before it).
