Hi all,
To clarify the problem (or to do just the opposite), here is a testfile with
a number of possibilities.
The file is made for 3 music lines in order to see a behaviour when an
automatic new line occurs.
This are my taughts on this
Bar 1 - multiple meters
bar 1 beat 2 and 3 signature change is this common?
bar 1 beat 4 the 'f' in the lower staff shows how confusing this is
bar 2: i vote OK
bar 3: autoamatic new line this i vote OK, but not the different signatures
in the instruments
bar 4: OK
bar 5: better
bar 6: rather not? or is it forbidden? Select one ot the 3 lines in the
source to see other behaviour.
bar 7: OK except on beat 3 (keychange on only 1 instrument, signature change
without bar line)
bar 8 and 9 : both OK or is there a preference?
bar 10: a meter without fraction
bar 11: Ok except the bass clef schould be repeated, is this possible?
bar 12: probably not.
