External control of poly~ properties

I'm having some trouble controlling parameters of a poly~ object I've created in the main patcher. In the patch I've built I have a poly~ object acting essentially as a bass drum, controlled by a rudimentary step-sequencing subpatch. The subpatch controls amplitude, which is sent with a "note" message to trigger the poly~. When I introduced controls over the frequency of the oscillator and the frequency of an svf~ filter, it seems as though the messages were only sent to the instance of poly~ occurring when the changes were sent. I attempted to resolve the issue by sending a bang at the same time as the "note" message to the numbers in the main patcher controlling pitch/cutoff in the poly~, thinking this would make sure the numbers were sent to all instances of the poly~, but this resulted in some other strange behavior. The patch is kind of involved but I can post it if need be. Any suggestions?
