thanks !
yes, with [delay 0] it ensures to get the good result (same block)...
(also tried to get an undesired behaviour without [del 0], but didn't
succeed !)

i already used [delay 0] sometimes, but i don't see where it's role is
documented

i already knew [bang~] but with this object my doubt was always : "i know
that it will happen *every* block during message-domain computation, but
*when* in that block ? relatively to other "not-triggerred" objects like
[env~]..."

well, maybe i'm going too far with this... since you gave me a working
solution :-)

however, also sent this to the pd-list because i wonder if i'm the only one
to feel that this issue isn't very intuitive to solve...

cheers,
