Frank,
The theory for this technique is here: http://crca.ucsd.edu/~msp/techniques/latest/book-html/node187.html (snip) Basically the whole construct below each [wrap~] is just the equation from there in Pd patch format.
Thanks Frank, the whole thing makes since now.
Not really: Numbers directly connected to [phasor~]'s first inlet get converted to a constant signal inside of [phasor~] automatically now. IIRC this wasn't the case for older versions of Pd, and then you had to use a [sig~] in between to do the conversion from message to signal.
Studying *nix in parallel with Pd, I am almost about to build a habit of assuming that anything looking obscure at first sight is there simply for "historical reasons" :)
Thanks again.
