Hi Rob,

The general principle is to use as many delay lines as you need. Multiple
delay lines with the same input signal are automatically optimized by the
compiler into a single delay line with multiple tap outs. For example the
Faust expression :

 _ <: @(7), @(11), @(13), @(17) :> _

takes an input signal *x[n]* and produces an output signal *y[n] =
x[n-7]+x[n-11]+x[n-13]+x[n-17]*. But only one delay line will be used in
the implementation.

Cheers

Yann
