Distorted Sound when switching from Kontakt to Audiotrack

When I load any kind of instrument into Kontakt as a rack instrument,
play few notes and then click on an Audiotrack, not related to Kontakt, the sound gets distorted.

  1. Empty Template
  2. Load Kontakt plus an Instrument, ideal something non percussive as a Rack Instrument
  3. Create an Audiotrack
  4. Play some notes on the Kontakt Instrument
  5. Switch from the Instrument Track to the Audiotrack while Kontakt is still playing.
  6. Distortion
