Hi,

I'm interested in playing a scorefile in my program. I've tried to use  
both the Score object in conjunction with the ScorePerformer object and  
the ScorefilePerformer object by itself; but none worked. I'm not really  
sure what I did wrong. I did something like this for the first method (and  
something similar for the second method):

score = [[Score alloc] init];
[score readScorefile:"/NextLibrary/Music/Scores/Emma.score"];
sp = [ScorePerformer new];
[sp setScore: score];
[sp activate];
[Conductor startPerformance];

It looks like it's correct, but I must be missing something. If someone  
can please tell me what it is that I'm missing, I would really appreciate  
it. Also I would like to know what's the difference between  
ScorefilePerformer and ScorePerformer. Thanks.

You are missing a connection from the ScorePerformer (actually, its  
PartPerformer's NoteSenders) to some Instrument object (e.g., Midi or a  
SynthInstrument or two...).  You should take a look at the examples:

/NextDeveloper/Examples/MusicKit/playscorefile
/NextDeveloper/Examples/MusicKit/playscorefilemidi

They show how to connect the individual parts in a Score file to  
SynthInstrument or Midi instances and how to configure the Orchestra and  
Conductor objects to work together.
