Usually what I do is to insert "invisible" \tempo marks to control midi
playback speed. Or more precisely, \tag them so that they are removed
from the typeset score, but included in the midi score. Something like
this:
myMusic = {
\tempo 4 = 120 % initial tempo
...
\tag #'midi \tempo 4 = 130 % tweak midi tempo
...
\tag #'midi \tempo 4 = 120 % set it back to "normal"
...
}
% Score for layout only
\score {
\removeWithTag #'midi \myMusic
\layout {}
}
% Score for midi only
\score {
\myMusic
\midi {}
}
