Other things to try in BiaB-

uncheck the 'fast generation' option
uncheck the 'use +/-' files option.
and
Disable the Lexicon in BiaB. I hate saying that, but I remember reading of many problems with that particular device. Deselect it as the audio input device and try generating as a test. If it is the cause maybe someone here can help get it set up correctly.

As John stated-
If you are using ASIO, which I think s required with the Lexicon, you shouldn't have two music apps open at once. ASIO is designed to be run one program at a time.


I do not work here, but the benefits are still awesome
