Converting or transforming a piece to a different time signature
I have a .mscz score in 4/4 time, and I want to convert it to 2/2 time (cut time).
Of course I want to change the time signature.
But I also want each measure to be replaced by two measures, quarter notes to change to half notes, eighth notes to change to quarter notes, etc., so that the new score is in a sense equivalent to the original.
What is that called, and where is the documentation on how to do it? Thank you.
I'm using 3.1.
