( What I specifically meant - which is practically no different then what you did - was just to type in @target 0 into the poly~ object box after @steal 1. I.e. initializing the object box with the attribute target 0. )
If it still doesn't work, just double check that you have the right midi input selected for notein (i.e. that you are in fact receiving notes) etc and if still in trouble do copy/paste once again both patchers so we'll have a look.
