Attractor (Value)?

pls, can’t figure out what is the effect of ‘Specify Parameters’ input.

‘0_o’

i said effect, but realy: what is the purpose of that pin???

i was expecting that i could define different attractors for different spread slices in one-on-one fashion, but no, this isn’t the case. than what is it for? i can’t see any effect of changing it’s state.
