Can someone tell me how to do multiple tracks by...doing one track and playing it over to for example add a bass line? since sforge is a single track audio recording software....how do i use vegas 4.0 to create a whole somg if i am the only musician? Please advise...Stephen
With Vegas you record directly to one or more tracks, whilst listening to other tracks you have already recorded.
Sound Forge is not necessary at this stage - you can use it later to post-process single events if necessary, but most of these things can also be done in Vegas.
Have you read the help or manual? Sounds like you need to catch up on some of the basics of how a DAW in general works and how Vegas does these things.
There is a lot to learn here. You may even want to pick up the new book on Vegas written by Douglas Spotted Eagle.
You might have wanted to look under the "products" pages and you could have found more than you ever wanted to know. Here's a good place to start for a quick overview of features.
