some critics on repeats
I have seen a lot of printed scores and there I normally find a segno twice.
At the Point where to jump and at the Point where you jump from. At this point you also find the mark D.S. al....
I think this is because you can also have multiple segni and then it also makes sence to have different Kind of marks.
There are mainly two Versions of "segno".
One is the one you have in musescore the other one goes down the bar and Looks a bit like the § sign (with 5 eyes :) ). Ok difficult to describe, you may look up "dal segno" at wikipedia.de. I like the § segno and sometimes I would like to write more then one segno-jump. Then the next Problem appears, because then I would perhaps have the D.S. al O-O (O=Coda-sign) twice musescore would not be able to handle this.
Before testing musescore I have scarecly seen a mark "To Coda" and I do not really like that.
Also for the Coda - Mark you have it normally twice. Nothing changed about that during the last 40 years, at least not in Germany.
Ok, musescore is may be good enough to get printable scores, because it is possible to put segni or Coda as much as needed. But if we want to get the scores played like musicians should do then there are Problems, additional Problems.
Let me say I have a part that should be repeated and before the start of this part I put e.g. some pp. Inside the part I somewhen change to mf. What will happen when the part is repeated ? Musescore will jump back to pp instead of keeping the mf which was set later. The musician will hopefully not change to pp. But why should he ? He would not read the pp any more.
