This is not right Pipeline and I went over this in your other thread about it. I know you're very good with computers and I hesitate to say this but you have overlooked something in your Windows Biab config. 4 seconds for the second Play is ridiculous. Remember the WASAPI thread? I got Biab down to 30ms using MME on Win 10 from hitting Play which while not "instant" is pretty darn fast. ASIO would be around 5-10ms which is probably where your Mac is.

Proof? Who else has this problem?
