Different time signatures for parts playing together in the same piece
Is it possible in MuseScore to have different time signatures for parts playing together in the same piece? I'm sure there are works which do this. For example piece in 4/4 could have one part written out in 12/8 which would perhaps solve some issues with writing triplets, and also allow dotted rhythms in the 12/8 part. Actually the dotted rhythms in triplets in 4/4 are not too difficult, but maybe 12/8 would be easier.
Could arbitrary time signatures be used in different parts, and linked together - for eample 4/4 against 5/4?
Also - even if it is possible to do this for engraving in MuseScore, would the player be able to render such a score?
