I'm building an external (my very first one) and it's working as

the variables set to get values from these arguments are set to zero.

The new instance routine prototype is this:
void *tabPowSine_new(t_symbol *s, short argc, t_atom argv)

Should be
void *tabPowSine_new(t_symbol *s, short argc, t_atom *argv)
, as argv is an array of exactly argc pointers to t_atoms.
