I've based myself on the old QuickEnvelope to create a new, similar one. It doesn't have nearly as much options, because I tried to KISS.

Also, I don't know almost anything about JScript or C#, so if anyone could optimize it or even port it to C#, it would be awesome.

It just creates Volume Envelopes in all tracks if only one is selected or if more than one is selected, just creates on those. Also, I've grabbed just the function to delete envelopes and made a separate script just with it.

The original (seems to be almost lost, can't even remember where I got it): http://pastebin.com/f230f9eba

Here's an old version I last updated in 2005 that adds 4 points to an audio envelope. It may need to be updated to run properly in Vegas Pro 8/9.

//Change this line to change the distance between the points

  var trackEnum = new Enumerator(Vegas.Project.Tracks);

  while (!trackEnum.atEnd()) {

    var track : Track = Track(trackEnum.item());





    //Now check for Volume Envelope

    if (track.IsAudio() && track.Selected) {

      // Find the volume envelope on this track - add if needed

      var VolEnv = FindEnvelope(track, EnvelopeType.Volume);

      if (null == VolEnv) {

        VolEnv = new Envelope(EnvelopeType.Volume);

        track.Envelopes.Add(VolEnv);
