Thanks Trev, interesting reading, buy way beyond my capabilities.

Without some manipulation, it's said the Edirol UM-1X does not work with Windows 10.

This is not correct.
After my "brainstorm" earlier today, I realised that I've had the Win 10 laptop for a couple of years, and it worked successfully (on Win 10) in BIAB2019 & BB2020. (and still does). Just not BB2021.

I wouldn't imagine that PG Music would have made major changes to the "nerve centre" of BB2021 that would affect latency. And it doesn't appear to have affected anyone else.

So I'm back to square one.

Maybe I'll uninstall BB2021, reinstall BB2020 and then add the BB2021 upgrade.

Desperate people do desperate things. smile


Cheers,
