[$1( is not the same as [$1]

[$0( is not defined at all (and thus set to 0)

$-args in objects are expanded to the arguments of the abstraction; the 
0th argument (which you cannot specify explicitly) is a "unique" number.

$-args in messages are expanded to the list-elements of the incoming 
list; there is no $0-element (well, this is wrong: $0 might be the 
selector of the list, but in the current implementation of pd it is not)

or use:

[vis_size 98 $1(

[s $0-cnv_in_01_01]
