Default Track Record Latency

Attached is a simple session with a JS synth on track 1 which routed to track 2 (an audio record track).

When I trigger the JS synth with midi and recorded the output of the audio track there is over 2900 samples of latency on the audio print. If I turn latency compensation for the record track, the audio is about 400 samples early. I have turned off media buffering and anticipatory fx for those track. I have no idea why routing a track in Reaper would cause such an alarming amount of latency.

I get similar reading with third party instruments like Kontakt and Serum.
Both tests seem to be wildly out of time. The audio interface for this test is set to 512 samples so even if thee audio interface is internally adding some latency it should only be 512 samples not close 3000. I have tested this on multiple machines with different interfaces as well as the dummy audio interface. I have also tested this on a portable install.

Any ideas about how to get Reaper to have zero latency or at least compensate the audio correctly?

The reaper forum is by far the most responsive I've seen compared to other DAWs and the user base is much smarter. This one issue that hasn't been fully sussed her has been discussed af length in another topic.

Thanks for checking in.
