Ive got a Delta 10/10, and vegas 4.0, and after the tracks have been recorded,
and the busses set to the master,everything is cool. no clicking or popping or
glitches.But the moment im done, i've saved tthe project,and i set it to render,
it renders nothing but a 7 second blank .wav file. Im utterly confused
Its not a demo or a pirated copy I assume? Make sure you haven't ticked the 'render loop region only' and its just rendering a 7 second blank. Also, make sure no tracks are 'soloed'. Start there.
It shouldn't have much to do with the Delta card.
