creating a varying amount of functions

Hi,
I am trying to a varying number of functions to create and update visual cues in jitter. The patch converts midi into a list (coll) and I am trying attach each of the values (time (y) and pitch (x)) to a paintoval message that will then send itself to the jit.lcd but I want the program to create the right number of functions to control each of the midi notes. I have tried using poly but it causes a lot of cpu usage and reduces the lcd to snapshots. II have also used a gate the reroute the messages to different sub patches but it doesn't seem to be very efficient as I have to name the values, sends and receives for each subpatch copy.
Many thanks.
