Just getting back to this now...that's right, changing out the kybd didn't accomplish anything. Here's what I know:
--I dont' have the latency problem in BIAB, only in RB
--it seems like using ASIO4All v2 is the only Audio Driver choice that I can get to work (MME and Windows Audio are the other options)
--When I open RealBand, or switch the Audio Driver to ASIO, or load a new file, I get a series of about 5 bleeps in my headphone
Mario, when you say "interface settings" what exactly are you asking about? settings in the driver control panel?
I'm going to shut down my browser to see if that makes a difference. Come back on the next message.
