Hi David,

Ok so I am having the exact same problem when recording in BIAB or in Pro Tools. So let's stop assuming that I do not understand how to record the user track.

I have come one step further in understanding what's wrong. Yesterday and the day before I was suddenly able to record perfectly aligned tracks and completed 2 user tracks that work absolutely fine. Today I wanted to start the 3rd user track and did everything in the exact same way and the recording was out of sync again! I tried a clean file (Song_1m_Jazz_1.SGU) and again it was out of sync.

To be clear: at this point I am only recording inside BIAB!

Now earlier when recording suddenly worked I noticed that my Pro Tools was open and thought maybe that's the difference (because it is using the same interface). So now I checked but it was open now as well. So I tried with Pro Tools closed. No change. Restarted my Mac, made sure all sound related programs were closed. No change...

Again: at this point I am still only recording inside BIAB!

I tested by selecting the built-in in/output of my Mac and now the recording was in sync! But yesterday it was in sync with my interface as well! So it's clear that somehow there is a buffering issue somewhere as you mentioned that sometimes causes delays and sometimes not. Is there a buffer size setting in BIAB 2020 (because there is none in my 2018 version)?

grts, Carlo
