This is what I input, setting the auftact amount as 1 beat (a beat = an 8th note):
It returns a signpost as “6/8 (e, 3+3)”:
It made me think that the “e” = “eighth note”.
However, when I change the auftact amout to other values like 2 beats:
It still shows an “e” there:
Also, the values of “pick-up bar of” shows that things are valued in “beats”:
However, tests proved that these values are actually valued in crotchets (quarter notes).
In case of using 6/8 beat… if you want to set the afutact amount as 1 beat (a quaver, i.e. an 8th note), you have to choose the “1/2 beat” in the context menu:
If you choose 1 beat in the context menu, the actual auftact amount will become 3 beats:
Something seems to be weird here.
