exactly.

if you connect any other thing to that same input port the "zero-copy"
issue goes away :)

side-note to who might concern: it has been previously reported as a
qtractor bug though, when doing this kind of direct loopback in a
brainless bouncing scenario. fact is, it's one half of the problem (jack
zero-copy optimization)--the other half gets to which track bounces to
which first (ie. depends on process/track order) and that's definitively
a qtractor's under-the-hood issue but not one i call urgent atm.
besides, jack's "zero-copy" issue remains still, attotw

alas, i am not that convinced it is a jack bug. if one, say a jack
client, ever wants to allow a direct loopback, why doesn't he/she do the
appropriate code him/her-self? it's a lousy memcpy() away isn't it?
