Are you sure you packed the right patches? There's not a single
[block~] used in that archive according to "grep block *.pd".

Anyway for this kind of "recirculating delayline" your lowest delay
time is one block in Pd because of the feedback. See Miller's T&T book
for a longer explanation.

You probably want to use more "$0-" variables for send/receive and
delay names then. I would recommend to make it a habit to *always* use
variables prepended with "$0-" and only skip the $0- if you really
want global access deliberately. Personally I'm even using UPPERCASE
names for these.
