when, after laying down basic drum track on track 1, I record guitar onto track 2 using simultaneous play & record, my track 2 records both guitar, & the drums from track 1. How can I get the program(vegas audio, btw,) to record the track 2 guitar discretely? Is this a sound card issue?
Double-click the little yellow speaker icon to bring up the sound card
mixing panel. Pull down the Options menu and click Properties, select
Recording and click OK. You will now see the inputs that your sound card
has. You probably have something like "Mixed Output" or "What You
Hear" selected. This means the card will record any and all sound signal
flowing through your computer. Check Line instead. This will make sure
that the only thing that your card records is the line input jack.
