rechannelizing per voice, with pitchbend?

here is the situation. i have a guitar to midi converter, ideally you have a dedicated midi channel per string, in order to have dedicated pitchbend data per string. i am using 2 hardware synths (nord and evolver) that have max of 4 individual midi channels each. SO I made this patch that takes the 4 most recent voices and sends them to 4 channels. But, now the hard part, any ideas how I could put pitchbend in? The problem I am running into is - how to attach pitchbend data to the proper voice. They come in on the same channel together, but the way apply notes to new channels per voice, means I need to find a way to keep the pitchbend with the correct voice. Any tips?

screenshot of the patch. this is the part that takes voice 1 and sends it out channel 1. the entire patch is this x4.
