Can anyone tell me what one is accomplishing when doing something like this:
[osc~ 440] | [+~] |\ x1 [+~] |\ x2 [+~] |\ x3 [+~] x4
In other words, the chain of [+~] that feed the previous object's output into both inlets of the next... what does this do exactly?
it adds a signal with itself: y=x+x=2*x
so the output of the 1st [+~] is x1=x0 (as the 2nd inlet~ is not connected) and the following [+~] will output: x2=x1+x1=2*x1=2*x0 x3=x2+x2=2*x2=2*2*x0=4*x0 x4=x3+x3=2*x3=2*4*x0=8*x0
so you could write the patch as:
[osc~ 440] | [*~ 8]
more often you see [*~] instead of [+~], which is a simple way to square the input.
