I have touched on this before but still have the same problem.
My dynamic range is really only at one level at the moment.
I do use the dynamic markings such as ff~C1,100 in sibelius which is fine to apply to a section but when i place crescendos, diminuendos (hairpins) the dynamic level does not change during or after the note in which it is placed.
I did try using the sibelius plug-in (cresc. dim.) but again with no success.
There MUST be a way to cresc. and dim.
If anyone can help me on this i would be very greatful.
