Hi Ibanezer,
In one sense, it
can just be busing in the track pane, but in a larger sense the way I think of it is moving away from a point-to-point routing scheme to a point-to-multipoint scheme.
So, in older versions I could output any one track, or "point", to any SINGLE other destination: a bus or side-chain; thus "point-to-point". A track output or send, for example, could go to only ONE destination. Now, I can output any one track to lots of places via a patch point, thus "point-to-multipoint". So now a snare could go to a patch point and then that patch point could be the input for a drum bus, a snare-reverb input, and a highly compressed crush/disto bus. Certainly you could do that before with outputs and sends, but this way it's organized differently (I would say faster) and, if you'd like, can be contained entirely in the track pane.
In fact, since patch points can have multiple inputs, you could think of it as "multipoint-to-multipoint", but Sonar was kinda always that way (multiple tracks could feed a bus, e.g.)
