MPC Key 61 Problem with unison notes on different tracks

Hey, y'all. I was trying to make a choral type project with a bunch of voice plugins over a 4 or more tracks, but whenever I play a note on the subsequent tracks that hits a unison with a note that's already sounding, the sound doesn't play and it totally ruins the sound of the track. It's not even the exact same rhythm or plugin... Does anyone know how I can get around this?

Depends on the plugin, I guess. Might be a polyphony setting, maybe even from the MPC itself. Hard to tell without more details. Did you try creating another (new) program with the same plugin or are you just loading the exact same plugin program on several tracks?
