I would like to change the trill speed in the midi output. I tried to change the "#(define..." like in the following code but without success. Any suggestion?
\version "2.19.81"
#(define ac:maxTwiddleTime (ly:make-moment 1/240))
\score {
\articulate {\time 2/4 c'2 \trill}
\layout {}
\midi {}
}
Thank you, g.
