The beat value in the transport menu normally reflects whatever Tempo mark I’ve set: e.g. crotchet, dotted crotchet, minim, etc.
However, if I set a più mosso instruction, then the beat value always shows as a crotchet.
E.g., in a 6/8 meter with a Tempo of dotted crotchet = 44, the più mosso shows 110% of q. = 44 as q = 73 !
This may be accurate but is unhelpful.
