[MU4 Issue] Tempo wrong when initializing a score with compound meter

[cmaxreilly]

When initializing a score that make initial use of a compound meter, the tempo played is incorrect. For example, when you make a score in 6/8, and set the dotted quarter equal to 120 in the new score wizard, it actually sets the quarter note to 120. This is easily worked around by simply selecting the tempo, deleting one of the numbers, retyping the number, and clicking elsewhere in the score, as in my examples.

Steps to reproduce the behavior:

1. Create a new score
2. Set the time signature to a compound meter
3. Set the tempo with a dotted quarter equaling a bpm
4. Press done
5. Write some music
6. Bpm has been assigned to the quarter note, not the dotted quarter note.

The new score wizard should be capable of assigning initial tempo to the quarter note.

I'm thinking this is probably the same basic issue as #14678, would you agree? Basically, doesn't matter what the time signature is, or what note value you select in the wizard - the specified BPM values always assigned to the quarter note when it comes to playback.

Yes, that would seem to be the overarching issue!
