Hi Martin,
Sorry for the late reply.
Thank you very much for you help.
I should have clarified that the non-integer tempo marking is for metric modulation in the middle of the score(not shown below),
hence the situation is complicated for the midi, but I guess I will settle for the score for now.
I modified your markup a little bit to keep the tempo font consistent (with the other tempo marking without using \markup):
%%%%%%%%%%
\score {
{
\tempo \markup {
\concat {
\smaller \general-align #Y #DOWN
\note #"4" #1 \normal-text " = 72.5"
}
}
c'
}
%%%%%%%%%%
