[PD] delay lines

Mathieu, just out of interest, what are the [phasor~] s used for?
Would I set up an array for both left and right traveling wave, or one each? and I don't understand how the data inside would be changing over time, if I use the excitation abstraction I have to put an impulse into , for example, the middle of an array, I don't understand how it would move along the array.
Sorry, I'm not a brilliant programmer, I have done digital waveguides in matlab, but I really don't like matlab and wanted to use a graphical real-time program, but Pd isn't as straight forward for delay lines.
