poly~ drone synth

I am trying to make a polyphonic synth that drones on multiple notes that I play on [kslider]

I am simply copying the "ezsynth" poly~ subpatcher from the help file but have tried a bunch of variations. I can't for the life of me figure out the poly~ for this purpose.
I have searched the forum and have spent a few hours trying to figure it out from the documentation and I feel really stupid cuz I've been doing some really wonderful things with max lately but I can't figure out poly~ for this or another project. It's literally driving me insane. Please help
