[Ken Fisher] "Are you saying there's no way to limit the number of audio tracks?"
If you drag media to the existing tracks it will use them. It's only when you drag the media to a new track that it makes both a new video and audio track. No there is no way to limit them. It just keeps making them depending on where you drop the media.
[Ken Fisher] "My problem or annoyance is when I do numerous voice-overs Vegas keeps inserting more and more audio tracks making the timeline harder to work with. "
I'm not sure how it's making new tracks. The way to do a voice over is to ARM the audio track that you want to record onto. Vegas will only record onto that track. You can even select an area of the track and have Vegas punch-in and out. Vegas is very rich in voice over capabilities and it can all be done on one audio track (I do this all the time).
