[PD] is there a way to send a bang precisely when a sample is looped using tabread4~?

So check while comparing each current sample [n] to the one before [n-1] for the moment [n] < [n-1]. You can do that with [expr~ if($v1<$v2, 1, 0)] and do for example the following:

In other words, pd by default does everything in 64-byte chunks (unless one manually alters this behaviour which with lower buffers results in a rapid increase in CPU overhead).
You mean like [block~ 1]?
