Oh that’s a given, I’m talking about routing a signal through several pieces of hardware and/or software in a particular way.

For example: the drummer needs to hear a clicktrack and the bass, while the choir needs to hear the orchestra/themselves separate (and they want a little reverb). (Now take this and apply it to everyone on stage)

These kind of situations can get very complex and can get very high stakes.

For those matters in windows you rely on the software that comes with your hardware. Problem is those don’t always play nice together. Or they simply don’t offer the particular situation you need.

In Linux you can do anything you want. So much so that it sometimes adds unto the complexity.
