Hi Bob,

I don't have that UA-25EX here to check, but I do have some USB audio devices here.

I will get an error message in RealBand or Powertracks if I have not yet plugged the USB device into the computer and let the OS recognize the device *before* starting up RealBand.

That might be the same at your end, worth trying.

I'm always forgetting and find out the hard way. Closing down RB, connecting the USB device, then opening up RB *usually* works. Running XP SP3 on that machine. When it doesn't work, I reboot and try again, it usually works then.
