You don't say how long the delay is or whether it's always the same length. Is it the same as the delay time through Cubase? Does it change in length if you change the I/O buffer size in Cubase?

My guess is that it's something to do with bringing the outputs back through the board, and that you sometimes haven't got a completely independent path for that. Could there be an Aux or Bus fader occasionally not zeroed causing cross-coupling?

So the delay seems always about the same time, it’s only a few milliseconds but a big enough difference to notice. Such as Sunday our worship leaders voice was being heard just a hair after the band was. But a week ago it was the kick and snare that was off. With the set up i have now I’m running out of Cubase to the 31 and 32 outputs on the si expression 3 and using a mix to send out to the livestream. Sorry if this is confusing.

OK, well a diagnostic might be to double the Cubase I/O buffer size and see if the delay quadruples (double on input, double again on output).

Ok so the only option through the Soundcraft control panel is an ASIO buffer size. It is set to auto but it does not give me an I/O option. Also the in and out latency are exactly the same. I’ve attached a picture.

It's normal that the in and out late cues are the same.

What happens when you drop down the other options (down-arrow on the right)?

The Clock Source? It will not let me. It only gives me the computer option. The buffer size i can go from auto up to 4096

It's the buffer size that's of interest for this test. Since you don't know easily what Auto sets it to, try a run with it at 1024 and then another at 2048. See if there's any difference between the two, and, if so, the ratio between the two different delays.
