* if you add lots of individual patches the Input goes through each patch simultaneously and the output is the result of how each patch changes the sound i.e the Output is the result of how each patch individually processes the sound i.e output = Patch A + Patch B + Patch C
* but if you write a complex patch where Output A is then fed into patch B and then Output B is fed into patch C etc... that Output A is modified by B and Output B is modified by C... i.e at each step it is working with an already modified signal rather than the original audio input i.e A -> B == A {transformed} -> C == B {transformed} [meaning effects are cumulative]
The attached image shows the process with A -> B -> C as a chain and then as Individual patches.

Hope the question makes sense.
