List of bars with their time signature for the cycle. A cycle can be made of several bar with different time signatures, for example:
4/4 4/4 3/4
Represents a cycle of two 4/4 bars and a 3/4 bar, so 11 beats. Allowed time signatures are x/1, x/2, x/4, x/8, x/16.
Moreover, you can define a precise tempo for each bar, for example
4/4=120 3/8=90 7/4=100
The first 4/4 bar will be at tempo=120, the second 3/8 at 90 and so on.
