It's a rather complicated setup, but here goes:

The UM1X interface is Y shaped with 2 DINS and 1 USB plug. One DIN goes to MIDI OUT on my keyboard, and the other goes to MIDI IN on the Ketron. The USB goes into the laptop. From the laptop the cable goes into the mixer, and then onto the amp.

Now here's the perplexing thing; I have two laptops, one has BB2020 and the other has BB2021. The BB2020 works perfectly, but if I disconnect the two cables and connect them to the BB2021 computer, the latency happens. Both versions are using the same song files.

I'm currently going through every setting, comparing the values set in BB2020 & BB2021. So far all of the settings are identical.

I feel that it's something very simple, but I'm getting frustrated because I can't find any variations, and I'm getting desperate to use BB021.

And Matt, yes, I've done Return to factory Setting, both "most" and "full"

And guys, I really appreciate you trying to help me out. Thank You.


Cheers,
Keith
