Hi there,

I'm totally stumped.

I'm trying to accurately measure the latency of my system for research reasons. I send a signal from MacBook Pro (10.12.6) running Pro Tools 12.8.2 out of my Scarlett 18i20, then using a cable I plug the signal back into an input. When I record this input, the recorded signal is 1ms earlier than the waveform of the original signal being sent out

This doesn't change when I relaunch PT, when I try at a different sample rate, with delay compensation on or off, with a different signal, or when I change the hardware buffer size

There are no plugins being used, and no h/w insert delay

My rig is prophetic!!

I can only presume there's some sort of automatic latency compensation going on that is malfunctioning. Anyone know anything about this or how to turn it off?

Thank you kindly for your time!
