I updated from Kontakt 8.7.1 where I did not have this issue to Kontakt 8.7.2 and now I am having this issue which after a search, seems to be something that people have had in the past…and now the present. Basically, any MIDI tracks that are about to trigger sounds in Session Percussionist cause the entire audio output of my system to go silent for some period of time… and then come back. If I keep the MIDI channels that will trigger sounds in Session Percussionist muted, then I don't have a problem. THis happens regardless if S.P. is being hosted in Komplete Kontrol or Kontakt. As of now, Session Percussionist is not usable. It was usable in Kontakt 8.7.1
