FourPoints Script Not Working

[John Rofrano]

> Failed to add envelope point (point may already exist at that location).

Do you have an envelope point at the location already? I’m not familiar with the script but I assume you must first make a timeline selection and then it creates a 4-point envelope within the selection. Perhaps you didn’t make a timeline selection first? If you can point me to the script, I can take a look for you.

Here’s the current version of that script for Vegas Pro 8.

foreach(Track track in myVegas.Project.Tracks)

else

}


Just save it as “FourPoints.cs” and it should do the job for you. You do need to have a selection area (it will still work even if you don’t but won’t give you what you want) and a selected audio track.

Thanks Ed, I had the audio track and the event selected, but I didn’t make a selection area–that did the trick. Cool, your script will save me a lot of time editing, appreciate it a lot. Bill.
