What Voices do inside Drum Maps Setup?

Hello, I can’t find in the manual what the Voices menu does inside the Drum Maps Setup, I think that it limits the number of notes playing simultaneously for the same kit note; someone has a more in depth explanation about this option?

It’s not about limits.

I give you an example:
when you work in the Score Editor, with a drum staff set to polyphonic, the notes you input are placed in the voices according to your Drum Map settings.
