I got stuck redoing an lfo for polysynth where each voice has it's own lfo osces but the tables sit in a parent patch. Its easy to name the lfo tables $0lfo1 ,$0lfo2 . It is not so simple when putting the table in an abstraction that can be reused. I guess just name the table $2$1 and pass in the creation argument lfo1 $0. For some reason though other things got confusing inside the abstraction.
