[PD] pause writing to delay line / hybrid of array and delay

You could have a looper feeding into a variable delay line whose delay is
A looper would be an N-sample feedback loop with some input feeding into
it, where the input gain and the feedback gain are mutually exclusive. That
would prevent new elements from being added and you'd have the same
recirculating material when you freeze it:
y[n] = Rx[n] + (1-R)y[n-N]
with R being 1 to write into it, or 0 to freeze it.
The output of the looper could then feed an N-sample delay line whose delay
is offset consistently to always point to the same buffer position:
delay[n] = (lineN[n] + element[n]) % N
lineN[n] = (1[n-1] + lineN[n-1]) % N
and element[n] is an int between 0 and N - 1 determining the array element
that is being output.
I don't have this in PD but here's the Faust implementation:
