I don't understand why not doing this:

It seems to be the same thing.

from [poly] help file:

"The [poly] object takes a stream of pitch/velocity pairs and outputs 
triples containing voice number, pitch and velocity.
  You can pack the output and use the route object to route messages 
among a bank of voices depending on the first outlet.
  [poly] can be configured to do voice stealing or not (the default.)"
