Multitap delay line implementation.
The arguments itime and igain set the position and gain of each tap.
The delay line is fed by asig.
a1 oscil 1000, 100, 1 a2 multitap a1, 1.2, .5, 1.4, .2 out a2
This results in two delays, one with length of 1.2 and gain of .5, and one with length of 1.4 and gain of .2.
