Hi Noel,
Thanks for the response. I checked through as you suggested, but my window is different to yours, although I don't suppose that makes a difference as the speaker volume is set to 100%.

I tried MME and it worked, but the latency was terrible.
Now the strange thing is that I reverted to ASIO which fixed the latency AND the keyboard now works and shows on the THRU meter.
I then tried recording and it placed a new track with the recording on it !!
So it all seems good for the moment, but don't ask me why it works now and not earlier, maybe a couple of restarts sorted it out and it's working with ST2.5 with no perceptible latency.

I don't think I'll play with anything else while it seems to be working !

Another question: Have you had any luck with the ASIO Multi-client wrapper when using more than one interface?
Just thought I'd ask before screwing anything else.

Thanks again

Al
