Help with setting up repeats & DS

Be aware that you can use the play panel to temporarily override the tempo for tests such as these (speed up to 300%)

First: uncheck "play repeats" for the D.S. marking as you obviously don't want it to do so.

Next: it is important to understand that a Jump (such as the D.S.) in itself does not mean number of previous repeats + 1. If play repeats is checked, it means start from the earliest repeat in which the segno is present (which in this case was repeat 1). If play repeats is not checked, it means "play the last repeat".

Now according to standard notation the last repeat is the highest repeat number possible, not accounting for jumps. So it only looks at repeat barlines and their count. As you only have a single end-repeat barline at the end of volta one pairing up with the start repeat at the start of the score, the maximum number of repeats is 2.
And a volta meant to play on repeat 3 thus will be skipped when jumping back and playing that last repeat (number 2).

Solution:
1. Replace the D.S. with a D.S. al Coda
2. Add a To Coda to m31
3. Add a Coda to m34
4. Remove the volta 3
5. Select the first chord of m34 and turn of "play" for it (as this is basically the end of the tied note).
Optionally add grace chord before and tie that in for the visual effect.

Workaround to maintain current visuals:
1. Double click the D.S. al Coda to change its text, make it read "D.S." again
2. Select the To Coda and Coda and mark them invisible
3. Add a plain text line where volta3 was and adjust style settings to match those of a volta.
4. If you've used the grace note trick before, slightly adjust their position to the left as well as give the main chord segment a negative leading space to show a bit longer ties without displacing the main note.
