So, here is a session I just created from scratch, using only the Precision Delay from UAD. (https://we.tl/YhyzoFenR6)
I named the song with the actual BPM and time signature that I saved in each Global Snapshot.
When you recall the snapshots directly or through the cue list I made going from song 1 to 5, Song one is properly recalled, as well as 2 and 3, but going to song 4 is recalling something really strange, as well as song 5.

And if you always go one step forward or Backward (like you would do in a sequenced show) if you do :

Song 1 = OK
Song 2 = OK
Song 3 = OK
Song 4 = not OK
Song 3 = not OK
Song 4 = still not OK
Song 5 = not OK
Song 4 = suddenly it’s recalling the right values !!!
Song 5 = not OK
Song 4 = OK
Song 3 = not OK
Song 2 = not OK
Song 1 = always Ok, because unsychronized (that’s my guess).

I tried to put the same time signature in every snapshot (1/4) and just move the tempo consequently to get the right time I was looking for, but it is still the same problem.

I think tempo changing is messing somehow with the time signature of this delay.

Any guess ?

Thank you very much.
