I would like to have one instrument track play in one time signature and another instrument track play in another time signature simultaneously. I understand that adding signature tracks changes the overall meter for all tracks. How do you make time signature changes for individual tracks? I would like to have polymeter at any given point. I would like to have the metronome acting accordingly clicking multiple time signatures simultaneously.



This is not possible in Cubase. The Time Signature track is global.

What you can do is to make a sum Time Signature and use the Metronome presets to hear the one you want to. For example if you have 3/4 and 4/4, make 12/8 Time Signature.
