[PD] Fibonacci (got a strange problem in pd)

[Roman Haefeli]

hi

it is quite difficult to see, where the problem is located.afait it IS a
problem of exeution order, but it is not possible to SEE where it is,
because there are sometimes more than one connection per outlet. this
means, the execution order is not defined. in order to make the patch
more readable, insert a trigger-object as you used it after the
bang-button. you can also set 'f' (float), 's' (symbol), 'l' (list) or
'a' (anything) as a arguments.
and: do not use [del 1] to define the order. use [trigger] too.  in case
one bang follows another within less 1ms, the [del 1] is too slow (i
admit, this is true only theoretically, in fact the shortest time
between 2 bangs is 1.45ms because of the controlrate of pd
[64samples/44.1kHz]) .  the only way to be sure that your patch is
working correctly is using triggers, triggers triggers...... :-)
i attached a slightly redesigned version of your fibonacci-patch.
