Hello Sonarians,
 
Here's a fun one: VocalSync a track, then the playback stops working. If I disable plugins thereafter, playback will work. 
If I go back to enable Plugins (FX button) then I get the Audio Engine has been stopped unexpectedly. (ya think?)
Evil.
Any quick ideas how to solve this? Changing buffers does nothing. 
Latest Platinum, Win 10 mondo-box.
I have an Audient ID22 which sounds great as an interface.
Thank you.
