I try to use Faust as an imperative language and signals as arrays. To
calculate the shape of my waveform (my array) at time T, I use the
previous values (T-1 and T-2).
I must restart from scratch...
Thanks Oleg for your attention !

I have no idea what are you trying to do, but this code looks wrong in any case
or I am totally confused.
ba.take(i+1,[email protected](1/sr))
looks doubly wrong. ba.take() doesn't make any sense to me, I fail to understand
what it should do. Say,
process = par(i, 2, ba.take(i+1, 0));
is simply wrong and won't compile.
Also. [email protected](1/sr) refers to the same signal 'x' you are trying to
define,
this can't work. For example,
x = x@1;
process = x;
leads to the endless evaluation cycle, and perhaps this explains the crash.
