I have a USB interface M-Audio Pro Fast Track Pro. I would like to
record the audio coming off of it in a separate file. There are
programs that allow this for regular PC soundcards; apparently they
create a temporary audio driver . The manual states that the MAFTP can
duplex, that is, record and play at the same time. But I haven't been
able to make this work with any of the programs. I want to record
streaming audio and similar on the same computer it is playing on.

I''ve tried changing drivers in various places until I'm blue. No
signal across any recorder so far.

Ideas?
