Hi Jacopo!
I think
\set Timing.tempoWholesPerMinute = #(ly:make-moment 24.715) % that is 98.86/4
should work for the midi output. At least it accepts floats. Combining it with
Michael’s solution for the markup should get you the complete \tempo
I might have heard sometime in the past that tempoWholesPerMinute got
internally rounded down the line. Do any of you in the developing team know if
this has been fixed?
Anyway, one other caveat to keep in mind is that it is much more common for
musicians to see a fractional tempo mark (printed in the score/part, regardless
of whether it is motivated by fixed electronics or film) as a reason to sneer
at the composer than for it to carry any useful information for their
interpretation.
