You can change the time signature at any point in your Ableton project using time signature markers or by adjusting the time signature fields in the Control Bar.

What is a Time Signature?

A time signature indicates how many beats are in each measure and what note value constitutes one beat.

For example, a 4/4 time signature means there are four beats per measure, with each beat being a quarter note.

Changing the time signature can help create different rhythmic feels and is used in various music genres and compositions.
