Re: MIDI output trick

[Mats Bengtsson]

What LilyPond version are you using? In recent versions, there's no need to
use \applymusic, rather you can use the function \unfoldRepeats as 
described
in the section on "Repeats and MIDI".

Also, this function should not have any influence on the MIDI instruments.
I think you original problem was due to something else. Since you didn't
include any complete example, I cannot provide any more specific help,
but don't hesitate to send a new question to the mailing list with more 
details,
if you want to sort it out. Anyway, there should be no reason to unfold your
repeats by hand as you proposed below.
