Re: How to handle changing transpositions

[Jan-Peter Voigt]

Hi Kieren,

I modified the example for the auto-transpose engraver a bit, so it uses 
a music and a global variable. I merged them in one Voice, so that the 
cue names are not printed twice. But that is not necessary for the 
transposition.
If the music is in concert-pitch and transposed to instrument-pitch midi 
is OK. In the other direction print is OK, but midi is wrong.
That is no problem to me, as I mostly enter music in concert-pitch and 
just have to display it in instrument pitch.
One thing to take care of: When music is used twice - for example via 
repeat unfold - every event is transposed multiple times.
That should be changed.

HTH
time to sleep now ;)
Best, Jan-Peter
