Fractional/Tuplet Time Signatures
As discussed in http://musescore.org/en/node/10903 I think it would be extremely beneficial for MuseScore to better support fractional and tuplet time signatures. Tuplet time signatures (4/3 or 4/6 etc, which would be four half notes from a half note triplet or four quarter notes from a quarter note triplet, respectively), although technically supported, are impossible to notate because you cannot split the bar into the desired space. Thus, if you were to place a quarter note in a bar of say, 5/6 (which would be 3 and a third quarter notes per measure) you would have that third of space showing, except with an infinite number rests as anything one third is not divisible by anything (1/2)^2.
Fractional time signatures would make this easier, as for example:
4/4 one. . . two. . . three. . . four. . . 5/6| one. . two. . three. . four. . five. . 4/4| one. . . two. . . three. . . four. . . | ||
is typically harder to understand than
4/4 one. . . two. . . three. . . four. . . 3+1/3/4| One. . Tri. . plet. . Three. . Tri. . 4/4| one. . . two. . . three. . . four. . . | ||
As triplets are used much more commonly than bars with a time signature denominator of six.
One option without this addition would be to find the lowest common multiple of the denominators of the two time signatures. For example, using the previous example above.
12/8 one. . . four. . . se'en. . . ten. . . 10/8| one. . three. . five. . se'en. . nine. . 12/8| one. . . four. . . se'en. . . ten. . . | ||
The only problem with that is that it might get lengthy, and be confusing. For a new example, with eleven-uplets. Say I want seven 11:4 quarter note eleven-uplets in a bar. Without fractional or tuplet time signatures, you'd have to write the song like this, even if just for one bar.
44/32 one...........12...........23...........34........... 28/32| one....5....9....13....17....21....24.... 44/32| one...........12........... etc
I think that is extremely difficult to comprehend (it took me at least ten minutes to figure out how to write it, plus a bit of paper and a calculator). Not to mention that every other bar in the song would have to have a quarter tied to a dotted 16th note for the traditional quarter in 4/4 (like the dotted quarter in 12/8 is equal to the quarter in 4/4 in the previous example).
Thank you for anything you can do to make a musician's life easier, and thank you for making MuseScore the incredible and probably best notation program in the world today.
