The problem I have is when I am playing notes in a VST plugin I was using Spitfire audio BBC SO core in Logic Pro,the sound of the notes change in tone or sound out of tune and do not sound as they relating to that particular instrument(s). I have 2 key steps and happens with both units. I have run the same VST in ableton live 11 and there is no problems. Has anyone reported similar problems with the keystep and Logic Pro?
