Midi Keyboard sounds great, then rattles, then good.... ad infinitum

swill0101

I have a Yamaha p-95 midi out to Komplete Audio 6 MK2 and using Kontact. I can get a beautiful instrument sound through my connected amp and then the sound rattles, but on key to what I'm playing, then sounds good, then rattles in key…. back and forth. My use case is to play different instruments through my mac in performances. This happens if I use the keyboard in Kontakt or the physical keyboard

Sorry if this is overkill below….. just trying to cover the bases for those that would like to help me out. Thanks in advance!!
