Currently when I open up Kontakt Player, I am not getting any sound coming out of the midi piano on the screen. I'm having this issue with multiple instruments. I do see that it is receiving signal, but so sound comes out. There are a few files where it does play sound, but not all of the instruments or notes are sounding where they are highlighted in blue.
In addition, I do use Sibelius and all of my default sounds are playing there. I'm only getting this issue through kontakt and this happen when I open Kontakt player independently too.
